Expanded polystyrene (EPS) foam, commonly known as styrofoam, the ubiquitous lightweight material used in packaging of electronic devices, food items and electric appliances, is popularly used because of its water and heat resistant properties. These properties likewise make it a preferred material for disposable food containers such as bowls, plates and coffee cups.

styrofoam-recycling

Due to its popularity, the global demand for EPS foam and its production is steadily increasing.  According to GBI Research, the global demand for both polystyrene and EPS increased to 14.9 million tons in 2010 from 13 million tons in 2000.1 This is expected to further swell to 25 million tons by 2022, 1.7% of which, or close to 400,000 tons coming from the Middle East.

The increase in EPS production necessitates intensified recycling efforts.  After all, a greater supply of EPS would result to more polystyrene waste, which, when disposed of in landfills take up significant space because of its bulk.  Furthermore, because of its light weight, it can easily be blown away and litter streets and water bodies, and clog storm drains. Being non-compostable and essentially non-biodegradable, it would take hundreds if not thousands of years for EPS to decompose.

The technology to recycle polystyrene already exists and recyclers have been producing goods from recycled polystyrene for years.  One of the reasons why polystyrene waste recycling is not very popular, even among recyclers, is the high cost associated with transporting the waste because of its volume to weight ratio.  A truckload of EPS foam actually contains very little polystyrene, with 95-98% of its content being air.

The cost can be lowered considerably by reducing the volume of the waste, preferably at the point of origin, before transporting to recycling facilities.  Volume reduction equipment offered in the market include balers, compactors and densifiers – these terms are sometimes used interchangeably by manufacturers – and the main differences in their processes are as follows:

1. Baling

Balers use hydraulic ram to compact EPS waste either vertically (from above) or horizontally (from the sides).  The resulting bales are tied with a strap or twine to keep them together and for easier handling and transport.

2. Cold compaction

The volume of EPS is reduced without using heat.  EPS waste is fed to a pre-breaker where it is broken into flakes of roughly 1 to 2 inches in size.  Using an auger or screw compactor, it is then compacted hydraulically into “logs” or blocks, achieving a reduction in volume of up to 98%.  The compacted polystyrene can be broken into size or transformed into pellets.

3. Thermal densification

Thermal densifiers such as StyromeltTM use heat to melt EPS and liberate trapped gases. The melted resin is then allowed to cool into briquettes or strands.  This process achieves a greater compaction rate than most hydraulic compactors and results to a product that is sterile.  There is, however, the issue of the release of vapours in the workplace and the smell created once EPS is heated. Most manufacturers resolve this by installing air filters on the equipment.

EPS-recycling

For companies, organizations or communities that receive and dispose of large quantities of EPS annually, buying or at least renting a volume reducing equipment could be a worthwhile investment.  With reduced volume, garbage skips need to be emptied less frequently, reducing labor and transportation costs. As the oil prices and demand for recycled polystyrene products increase, so does the price for compacted EPS.

Although the prices may vary depending on the quality, compacted EPS could sell at £350 (US$530) per ton, with some recyclers willing to pay more for large quantities.2,3  Some recycling equipment suppliers or leasers even buy the compressed product for a competitive price, easing the need to find a separate recycler to deal with.

Being thermoplastic, compressed polystyrene can be melted and remolded to different plastic products and recyclers are finding innovative ways to do just that.  It has been fashioned into CD cases, coat hangers, picture frames, toys and office supplies such as pens, stapler bodies and rulers.

Recycled EPS is also utilized to manufacture wood-alternative products such as interior decorative moldings.4  Such products are comparable to softwood but have the advantage of being both water- and mold-resistant, and of being impervious to rotting and decay.

Crushed polystyrene can be used as aggregates to produce lightweight concrete.  Rastra, a company based in Arizona, USA, produces Insulated Concrete Forms (ICFs) using 85% recycled EPS and 15% cement.5 ICFs are hollow foam blocks that are stacked and filled with concrete to form building walls.

Homes and buildings built with ICFs are more sound-proof, and provide greater thermal insulation, making cooling and heating equipment more efficient.  In South Africa, a new patented formula is being used to manufacture building panels from waste polystyrene, and plans are underway to build one million homes using the said panels.6

Recycling polystyrene certainly shows great promise and more ways of utilizing recycled polystyrene will likely be discovered in the future.  Hopefully, the promise of greater profit, not to mention a cleaner planet will encourage companies, organizations and governments to step up polystyrene recycling efforts.

World Habitat Day 2017: Affordable Homes

By | |
Leave a comment

World Habitat Day, observed every year on the first Monday of October, is meant to reflect on the state of our urban areas and the basic human right regarding provision of adequate shelter to all human beings. World Habitat Day (WHD) also aims to remind the planners and government officials of the collective responsibility for the habitat of future generations and a day to encourage grassroots action from civil society organizations to advocate for universal decent housing.

Each year, World Habitat Day takes on a new theme chosen by the United Nations based on current issues relevant to the Habitat Agenda. The themes of WHD are selected to bring attention to UN-Habitat’s mandate to promote sustainable development policies that ensure adequate shelter for all. These themes often promote important subjects such as housing and social services, a safe and healthy living environment, affordable and sustainable transport and energy, promotion, protection and restoration of green urban spaces, safe and clean drinking water and sanitation, healthy air quality, employment generation, improved urban planning, slum upgrading and better waste management.

The theme for World Habitat Day 2017 is Housing Policies: Affordable Homes. The purpose of WHD is to reflect on the conditions of our cities and towns and on the basic right of all to acquire an adequate shelter. It is also intended to remind the world that we all have the power and the responsibility to shape the future of our cities and towns.

This year WHD will focus on promoting at all levels of decision making on how to implement concrete initiatives to ensure adequate and affordable housing for all socio economic groups of people in the context of implementation of the New Urban Agenda based on Sustainable Development Goals.

An analysis of housing affordability over the last two decades reveals that despite increasing demand, owned and rental housing has been largely unaffordable for the majority of the world population mostly in developing countries. Around 1.6 billion people globally live in inadequate housing, of which 1 billion live in slums and informal settlements. While millions of people lack suitable homes. Ensuring housing availability and affordability is a complex issue of strategic importance for development, social peace and equality. Addressing the housing needs of the poorest and most vulnerable, especially women, youth and those who live in slums must be a priority in the development agendas.

The WHD is aimed at drawing the people’s attention towards the basic desire and need of poor people for an adequate housing. We need to understand that promoting sound housing policies is also crucial for climate change, resilience, mobility and energy consumption. For housing to contribute to national socio-economic development and achievement of the Sustainable Development Goals, the New Urban Agenda calls for placing housing policies at the center of national urban policies along with strategies to fight poverty, improve health and employment.

The WHD is aimed at drawing the people’s attention towards the need of poor people for an adequate housing.

The purpose of celebrating the WHD is to pay serious attention towards the need for better shelter all over the world, to share the priority of affordable and adequate housing, to bring the positive changes in the systems including policies and attitudes, to reflect on the states and towns and pay attention on the basic human rights for adequate shelter and to increase the awareness worldwide of joint responsibility for the future generation’s shelter.

Providing and improving housing is a gigantic task and cannot be dealt only by the governmental authorities. It require involvement of all stake holders including communities, NGOs and experienced developers to optimize urban densities and provide land zoning with efficient services and utilities that are environmental friendly and have minimum carbon footprint.

With the shortage of urban space, we need to develop in a sustainable manner to keep room for future growth and accommodate population in the coming decades. In the Middle East, the concerned authorities are giving due attention to the subject of planning and providing decent housing to citizens and to avoid any social, health and environmental problems.

Let us whole-heartedly support and celebrate the WHD and organize any activity or event in our own community including an awareness campaign, a fun activity, area cleanliness and get together in parks and public spaces.

Why Do You Need Eco-friendly Cleaning?

We’ve settled into a lot of different amenities over the years. From cars to washing machines to even the mighty toaster. Of course, just because we’ve built something doesn’t mean we’ve given up on trying to improve it in just about any way, shape, or form we can muster up. One of the newest ways to improve something that exists is to make it more friendly for the environment. One of the newest industries to get hit by the green wave would be the housekeeping industry.

What’s to gain from eco-friendly cleaning services? Lucky for you, I got to the bottom of it all:

Prevent The Creation Of Superbugs

All of these harsh chemicals that promise to kill 99.9% of germs sound great once you realize that all that’s left is what’s resistant to said chemicals and they now have their pick of the litter as far as resources in that area. These harsh antimicrobial products don’t offer any significant health benefits, while I personally consider the fact that they create an environment perfect for breeding superbugs to be the opposite of their intended effect.

Good Price To Value Ratio

Most of the industrial chemicals that are used for deep cleaning the house are quite expensive. By using eco-friendly cleaning products, Wimbledon cleaning services are able to provide their customers with affordable high-quality cleaning services that are safe for their health and easy on their pocket!

Better Air Quality

As nice as it is to have a house that looks livable, there isn’t much good in getting your home cleaned if it makes it unlivable thanks to all of the noxious fumes now circling in the air. Dry heat like that in Austin makes air already difficult to tolerate, any nasty extras come out twice as strong in that kind of climate. Often, people such as those interested in maid service Austin, have a desire to keep their air as crisp as possible to help beat the heat. No fumes, no worries, no hassle! Natural cleaning chemicals don’t have this effect which makes them great for those who suffer from allergies and regular breathing problems.

Sustainability

Most natural products are beginning to come in biodegradable or at least highly recyclable containers to further hammer in the full eco-friendliness of that product. It doesn’t get more eco-friendly than starting from the dirt and ending in the dirt, now does it? Another great thing about many natural cleaners is that they can be shipped highly concentrated and then diluted as needed, further reducing the amount of materials that had to be used.

If you have a penchant for keeping the planet as healthy as you possibly can, then it is a no-brainer that you should consider looking for an eco-friendly cleaning service as opposed to your regular harsh chemical style cleaner. Also try to invest in a maid service software.

If you’re lucky, you’ll manage to reduce your carbon footprint, your allergy medication bills, and your cleaning bill too. We’re becoming more and more aware of the fact that we have a limited amount of resources available to us and a surplus of people who need said resources; the eco-friendly movement is merely a natural continuation of our desire to get the most out of what we have now.

The Environmental Benefits of a Smart Home

By | | , , , ,

Smart home systems, with their extensive automation, sensing, and remote control capabilities, offer a lot of environmental benefits. If you’re not yet sure why this matters, consider that making your home more efficient will save you money as well as affect your carbon footprint. There are many ways to go about reducing your carbon footprint, and implementing smart tech in your home is a good place to start. Here are some of the ways you can use smart home devices to conserve energy and natural resources.

How Smart Home Systems Work for You

 

Temperature regulation

Smart thermostats are programmable, but the most advanced ones go beyond that, actually sensing what’s happening in the environment and adjusting to your behaviors. Simple programmable ones will help you save energy by kicking on the heat or AC only when you need it and adjusting the temperature when no one’s home. They offer more advanced programming than previous generations of programmable thermostats so you can set them for both weekday and weekend schedules, and you can also control them from your phone as plans change.

Some smart thermostats can sense if a door is left open and turn off the system in response, or even learn your heating/cooling preferences. Others can be connected to sensors in your home to trigger them to start or stop the HVAC system.

Home sensors

Speaking of sensors, there are various types of smart home sensors available for almost anything imaginable, such as light and temperature sensors, which will turn off lights and thermostats in case you forget. Leak sensors can be placed in out-of-the-way locations to catch leaks before you’d see evidence of them, saving you money in repairs and preventing water from being wasted.

The SmartThings motion sensor, for instance, can be placed anywhere in your home and programmed to turn on lights, set security alarms, adjust portable heating or AC, and other things based on your motion. Devices like this make forgetting to turn the heat down, the lights off, or the alarm on a thing of the past. Contact sensors can be placed anywhere something opens and closes to alert you if someone has accidentally left a window open or the fridge door isn’t shut.

Irrigation

Have a garden to water? Studies have found that smart irrigation systems can conserve from 30% to 50% of water used for this purpose. They do this by tailoring watering schedules to the needs of the landscaping and sensing environmental changes (an unexpected rainshower, for instance) that changes a garden’s needs, among other things.

There are a couple of types of smart irrigation systems, weather-based and soil moisture sensor systems. Weather-based controllers get hooked up to a network so they can monitor local weather conditions. Soil moisture sensors, as the name indicates, measure soil moisture content and transmit this information to a controller that determines when and for how long watering will happen.

Lighting systems

Smart lighting has a couple of components: the bulbs themselves and networked systems that provide automated or remote control of the lights being on or off. Start with smart lighting by replacing regular bulbs with something like Philips Hue bulbs, They’re LED, which is much more energy efficient, and offer remote control. Many of them offer temperature ranges, as well, so you can adjust the lighting environment as your needs change throughout the day. What’s more, LED bulbs are mercury-free; even efficient CFLs still contain this hazardous substance.

With a smart lighting system, you can remotely turn off the light in your kid’s room if they fell asleep without doing so, program lights to go on/off at certain times when you’re on vacation to give the appearance of being home without running them 24/7, and otherwise customize your lighting environment to provide only what you need while you need it.

Window treatments

Sometimes people forget how much of an effect passive cooling and heating via your windows can affect the indoor temperature. Smart window treatments can be hooked up to systems like Alexa and Google Home so they automatically adjust based on the time of day and your needs.

Such devices can provide energy conservation by taking some of the load off the HVAC system to maintain a steady temperature as well as helping out in other ways. For instance, if you have trouble getting out of bed in the morning, smart blinds can open when your alarm goes off so the morning sun can help wake you up. Blinds adjust themselves to block out sun in the summer and let it in during the winter. You can buy custom sets or upgrade your current window treatments with a kit.

Bottom Line

These are just a few ways smart home devices can be used for energy efficiency as well as increased convenience. The environmental difference such devices provide is not negligible, and neither is the cost savings: An EPA study found that just using a smart thermostat offered anywhere from a 10 to 30% savings on energy bills. Home electricity and water conservation, when implemented on a large scale, has the potential to significantly affect the pace of climate change. Start simple with a few smart light bulbs, or jump in with a central control hub such as Alexa and outfit your home with the range of smart devices available on the market.

How Vacuum Technology is Used to Create Core Energy Storage Devices for e-Mobility: Lithium-ion Batteries

By | | , ,
Leave a comment

You’ve got one in your pocket right now. Indeed, lithium-ion batteries are found in small portable electronics such as smartphones and laptops, in addition to being the heart of electric automobiles and vehicles. They are also used extensively in spatial and aeronautical applications. But what exactly are lithium batteries, and why are they so hotly debated today? What role does vacuum technology play with lithium batteries?

Vacuum Technology is Used to Create Lithium-ion Batteries

What exactly are lithium batteries, and why are they so important today?

Modern lithium-ion batteries have lately become the focus of today’s key conversations and debates, owing to their popularity as the preferred technology for electric vehicles. Unlike other types of batteries, lithium-ion batteries have a far higher energy density and a slower discharge rate, allowing them to hold a charge for much longer. Along with e-vehicles, they can also be found in small portable electronics like smartphones and laptops, as well as in telecommunications and aerospace applications.

The mechanisms at work

As a revolutionary and cutting-edge battery technology, lithium-ion batteries use lithium ions as the main components in the battery’s operation and electrochemistry.

Lithium-based energy storage systems are constantly being optimized. They are intended to push e-mobility to the next level by lowering production costs and increasing mileage.  The transition to electric vehicles is, in actuality, the most recent and remarkable evolution in today’s highly competitive market. They have already been identified as the future of transportation and are expected to overtake the automobile industry over the next decade.

E-mobility is the road to the future

Climate change, fossil fuel use, and ecological sustainability all seem to have a close solution in the new technological innovations of e-Mobility.

The European Union has requested countries to stop producing gas-powered automobiles to defend a key pillar of the EU’s plans to lower net global warming emissions by 55% by 2030. As a consequence, today major automakers have begun to develop their own electric vehicles — we are all familiar with the automobile industry’s pioneer, Tesla — and their car technology is rapidly progressing. Vacuum technology has been critical in this industry and continues to be the driving force behind those advancements.

Vacuum technology and electric mobility

In the mobility industry, vacuum technology has a lengthy history. It started as an industry-wide innovation roughly 60 years ago and has been used to help the production of automotive batteries for decades.

Such a pillar will be used for many years to come. Vacuum technology is still having a vital function in the most recent e-mobility advancements with lithium-ion batteries.

Agilent is a designer and supplier of vacuum solutions, and it offers practical options for effective energy storage problems. It helps manufacturers all over the world create optimal lithium batteries and lithium battery technology. It also aids the quality control process with the use of certain equipment. Vacuum and leak detection technologies, for example, are necessary as a quality measure in a variety of industrial operations.

Vacuum Technology is providing energy to electric vehicles!

Vacuum is already being used in a variety of functional stages and processes related to electric mobility. The very first step starts with a vacuum: the electrolyte-filling stage of a lithium-ion battery, for example, is fundamental to ensure that the cell is evenly saturated with the electrolyte.

Let’s examine the stages where vacuum is paramount to creating the precious energy storing device.

Vacuum technology in more than half of the lithium battery manufacture process!

Agilent vacuum specialists have long supported lithium-ion battery manufacturing with specific equipment and technological research for production and quality control. They now have an essential role with their vacuum technology accounting for more than half of the stages in battery production.

The excellence of the production line has a significant impact on battery performance, longevity, and general performance. Agilent technologies and expertise constantly work to optimize resource usage and minimize process time while maintaining product quality.

The lithium ion batteries manufacturing process

Starting with raw materials, the process is divided into three major stages that result in the desired, finished lithium ion battery.  The three main phases are electrode manufacturing, cell assembly and cell finishing.

lithium-ion batteries manufacturing technology

Each of these phases is made up of four subphases. More than half of the entire process is carried out in vacuum conditions or with the assistance of vacuum and leak detection technologies.

Electrode manufacturing

Base material mixing

The materials are blended together in the first stage. Under vacuum, active material, binder, and conductive agents are mixed to achieve the desired homogeneity, viscosity, and purity.

Vacuum  helps to remove air bubbles, which improves battery electrical performance and charging capacity.

Vacuum drying

Drying the laminated lithium-ion electrodes under a vacuum ensures that there is no remaining moisture. The precise and careful drying process is designed to avoid damaging electrode microstructure.

Cell assembly

Electrode degassing

The laminated and post-dried electrode surface has air pockets that must be eliminated via vacuum treatment. Impurities, residual gas pockets, and oil residues affect electrical performance, therefore dry, hydrocarbon-free vacuum pumps are necessary for electrode surface degassing to achieve optimal results.

Explore Agilent’s scroll pumps and their powerful, yet delicate vacuum technology.

Cell finishing

Battery electrolyte filling

Filling takes place under a vacuum to provide a uniform distribution of the electrolytes within the cell, ensure electrode wetting, and avoid inefficiencies caused by trapped gas bubbles. Vacuum pumps for this procedure must be able to withstand electrolyte residuals. This process done under vacuum increases battery efficiency and longevity.

Battery housing

Battery housing is crucial in e-cars for several reasons, including robustness in case of crash, chassis integration, and a lightweight form factor. Housings serve as battery protection and must be refrigerated, corrosion-resistant, and electromagnetically protected. Helium leak detectors are utilized here to ensure that the aluminum die-cast battery casing is sealed and watertight.

Battery testing

To suit the changing needs of vehicle manufacturers, technological advancements have led to the production of many types of batteries. Li-ion battery cells can have a soft cover in the shape of a pouch cell or a hardcover in the shape of a cylindrical or square. The leak tightness of both the battery module and the final battery assembly is crucial for ensuring high-quality standards in longevity, performance, and secure operation of the battery. Agilent leak detectors and dry pumps provide cutting-edge performance in detecting potentially dangerous leaks during the battery production process.

يعد الشرق الأوسط من  اخصب الأماكن في توليد النفايات عالميا, ويعد نمط الحياة المسرف, و التشريعات غير الفعالة, و معيقات توفير البنى التحتية, و السلوكيات العامة غير المبالية, و انقص التوعية البيئية من العوامل الأساسية المؤدية لنمو مشاكل النفايات في الشرق الأوسط. كما يسهم مستوى المعيشة المرتفع  مقرونا بعدم توفر مرافق جمع والتخلص من النفايات في تحويل موضوع "القمامة"  الى "مسؤولية" .

العقبات الرئيسية

ان الأدراك العام للنفايات يتمحور حول اللامبالاة و عدم الاكتراث, و يتم التعامل مع النفايات  على انها(نفايات) و ليس (موارد). وهناك حاجة ملحة لزيادة الوعي لدى العامة حول القضايا البيئية, وممارسات ادارة النفايات الصلبة و المعيشة المستدامة. وتتصف  مشاركة العامة في المبادرات المجتمعية لأدارة النفايات بالخمول وذلك بسبب تدني مستوى الوعي البيئي و التعليم العام. للأسف ليس لدى أي من بلدان المنطقة الية فعالة  لفصل النفايات من المصدر.

تعاني ادارة النفايات الصلبة في الشرق الأوسط  من قصور التشريعات و سوء التخطيط. ولا يتوفر في الكثير من الدول  تشريعات للتعامل مع موضوع النفايات, اضافة الى عدم كفاية التمويل, وغياب خطط أدارة النفايات, و  ضعف التنسيق  بين الجهات ذات العلاقة, وعدم توفر القوى البشرية المؤهلة, فضلا عن  ضعف القرارات الفنية والادارية , مما يؤدي بمجمله الى عدم قدرة تلك الدول على تنفيذ استراتيجية متكاملة لادارة النفايات في المنطقة. تسند صلاحيات ادارة النفايات في العديد من البلدان الى الشركات التابعة للحكومة و البلديات و هذا بدوره يؤدي الى عدم تشجيع مشاركة القطاع الخاص والرياديين في هذا القطاع.

على الرغم من تشديد  الأسلام على جوانب  تقليل النفايات, الا انه ولسوء الحظ فان  معدلات توليد النفايات للفرد في البلدان العربية هي من الاعلى في العالم.  بسبب عدم توفر المرافق المناسبة لتجميع النفايات والتخلص منها,فأنه من الشائع في المنطقة أن ترى النفايات ملقاة عشوائيا في الاماكن المفتوحة  والصحارى و المسطحات المائية. علاوة على ذلك فان قلة الوعي وتقاعس الناس عن تقليل نفاياتهم وفصلها عند المصدر وادارتها باسلوب صحيح يشكل  قضية حرجة أخرى

يحتاج النظام المستدام لادارة النفايات  الى  مشاركة واسعة من العامة, و تشريعات فعالة, و تمويل كافي, اضافة الى ا ممارسات وتكنولوجيا حديثة  لادارة النفايات. يأمل الأقليم في تحسين سيناريوهات ادارة النفايات عن طريق فصل النفايات في المصدر, و تشجيع مشاركة القطاع الخاص, وتطبيق أنظمة اعادة التدوير و توليد الطاقة من النفايات, وتطوير منظومة تشريعية و مؤسسية قوية ومؤثرة.

بصيص الأمل

في السنوات الاخيرة, قام عدد من البلدان مثل قطر و دولة الامارات العربية المتحدة, بانشاء مشاريع طموحة لادارة النفايات الصلبة, الا ان فعاليتها لم تؤكد بعد. و بشكل عام, تخطو دول المنطقة خطوات بطيئة ولكن ثابتة نحو التصدي لتحديات ادارة النفايات وذلك من خلال الاستثمارات الكبيرة في مثل هذه المشاريع, و ايجاد تكنولوجيا جديدة و رفع مستوى الوعي العام. غير ان سرعة التقدم والانجاز غير متوافقة مع معدل زيادة توليد النفايات في المنطقة. ان الادارة المستدامة للنفايات تعد تحديا كبيرا لصانعي السياسات, و المخططين الحضريين و غيرهم من الجهات ذات العلاقة, و هناك حاجة الى خطوات فورية لمعالجة جبال النفايات المتراكمة في مدن منطقة الشرق الأوسط.

Why Electric Vehicles Are the Future of the Automotive Industry

By | | , ,
1 Comment

Electric vehicles have come a long way since their invention in the 1830s. What was once a novelty for the Chicago World’s Fair is now a common sight on major highways. With Tesla now modernizing the industry, EVs are more attainable than ever in the world’s market.

Still, high price tags and a lack of charging stations at pit stops keep many car users from making the switch. Of the over 280 million cars in the U.S, only 2 million are fully electric or hybrid vehicles. So why are so many predictions pointing to EVs in the automotive industry?

Electric Vehicles Pros and Cons

Read on as we explore why EVs are instrumental to the future of the industry and the pros and cons of EV ownership in 2022.

Electric Vehicles Pros and Cons

Most conversations on EV ownership start with gas prices and end with charging stations. Yet many fail to explore the true impact of EVs and how initial setbacks to the industry are only temporary issues. A family of EV charging stations already exists at many gas stations along major roads.

With over 200 miles at full charge and portable charging plugs available, the initial fears of EV ownership are quickly rectifying themselves. Still, the benefits of an EV will vary based on location, average mileage, safety features and the make of the car.

Below, we detail the common and uncommon pros, cons, and misconceptions of EV ownership.

Pros

Skipping prices at the pump is the most popular pro for purchasing an electric vehicle. With gas prices always fluctuating, the initial cost of an EV is said to pay itself with the money you save from avoiding gas stations.

The second greatest pro rests in the eco-friendly nature of most EVs. Even hybrids that run on electricity and gas production have more environmentally friendly emissions than a normal gas-powered car. As the world shifts to a more environment-friendly manufacturing perspective, EVs are the natural evolution.

Though many worry about the charging capabilities of cars, a full charge from home can last over 200 miles. This is perfect for community use and short road trips. Utilizing mobile and turbo-charged charging stations can take you even further, with quick charges available in 30 minutes.

Some may worry about the cost of charging your EV at home through an at-home charger or chagrin station. Though a full charge from a depleted battery will take 48 hours to fill, it will only cost you 6$, or a little over ¢10 every kilowatt-hour.

So long as time isn’t a restraint for your commute, the at-home full charge is efficient and cost-effective.

Cons

Tesla is the current king of electric vehicles, servicing high-quality EVs at even higher prices. This makes it hard for other automotive manufacturers to break into the EV world, even if their vehicle can rival a tesla. Though Toyota has earned the #2 spot for EV production and sales, its product output fails to match Tesla.

Like Apple products dominated the early 2000-2010 markets, Tesla’s status as king of EVs creates elitism at a cost. Without true competitors, Tesla can continue to charge an arm and a leg and keep the market inaccessible for the average American.

Additionally, EVs aren’t currently compatible with rural or long-drive use. A fully electric vehicle isn’t feasible for driver-focused commuters in less populated areas if the area does not support local charging stations. Hybrid vehicles can overcome this issue, but overreliance on gas eliminates the benefit of your electric vehicle.

Looking to the Future

Though their numbers are limited in the current market, the potential behind electric vehicles is extensive. Sources suggest within the next ten years; the EV market will jump from 2 million to over 18 million. Though the growth may not rival the current output of gas-powered vehicles, the steady growth hints at a more EV-friendly world.

With major obstacles such as cost and lack of public charging stations taken care of, the electric vehicle market will finally reach more average American consumers. A surge in hybrid and fully electric vehicles will reduce reliance on fossil fuels, improve air pollution, and lower the average cost of living. Less money on gas can open wallets to invest in new experiences and opportunities in your new electric vehicles.

It may take a few years for the EV to become a true automotive rival. Still, with growing interest, investments, sales, and visibility, the electric vehicle will soon become a common sight during your next road trip.

Why We Need to Use Technology to Fight Climate Change

By | | , ,

Climate change is a colossal challenge, and it can seem like individual actions won’t be enough to tackle it, or that we don’t have the resources necessary. But neither of those are true. There are many individual actions we can all take that will help change the course of climate change. Many technologies available at both consumer and industrial levels can play a role, from simple things like switching to LED lights to complex processes such as building wind farms for renewable energy.

With so many people consuming our valuable resources, science says humans are a main cause of climate change. Rapid changes in climate due to human activity have been seen since the industrial revolution. There are other contributors to climate change, such as deforestation and land use practices, but our technological development is unquestionably a major contributor as well.

With so many people consuming our valuable resources, science says humans are a main cause of climate change. Rapid changes in climate due to human activity have been seen since the industrial revolution. There are other contributors to climate change, such as deforestation and land use practices, but our technological development is unquestionably a major contributor as well. Exploring innovative solutions like direct air capture becomes crucial in mitigating the impact of human activities on the climate and working towards a more sustainable future.”

Given that our technologies are not going anywhere, the best thing we can do with them is harness the full extent of their possibilities to mitigate the harm to the planet we have already created. And, at our current point, we need to use everything available to us in the fight against climate change; we’re running out of time. Let’s look at some of the ways technology can help us fight climate change.

Carbon reduction

One of the most promising technologies right now is negative emission tech. It aims to remove carbon from the atmosphere to offset the carbon going into the atmosphere. Of course, there are many ways to reduce how much carbon we put into the atmosphere, like reforestation and changing land-use practices, but those take time, and we don’t have a lot.

Carbon capture technology can help us reach a net-zero state by 2050 (or ideally, by 2030) if it is deployed soon. Currently, in pilot stages are machines that remove carbon from the air and store it underground, and other technologies are in the works.

Smart home tech

Remember when we said there were individual actions to take? One of the most promising is to use smart home tech, such as thermostats, lighting systems, utility meters, and leak detectors, to improve the energy efficiency of our homes.

Eventually, these local systems can be hooked up to smart city systems for more effective energy deployment, waste management tracking, and traffic management, among other possibilities. As the capabilities of the Internet of Things develops, both smart home tech and city-wide smart systems will become effective tools in tackling climate change.

Information and communication

As climate change progresses, severe weather events are becoming more and more common, and these events are costly and life-changing for many. The better we can do in predicting and managing severe weather, the more our recovery efforts will succeed. This kind of tech, for the most part, doesn’t do anything to change the direction of climate change, but it does help humans deal with the consequences.

Some examples of this tech are satellite systems using solar power and early warning systems via mobile networks. Information and communication technology is also being used to track environmental changes, such as temperature and sea level, to mitigate adverse effects on people and animals.

Machine learning and AI

AI is on the leading edge of our technological development and holds great promise for scientists working to better understand and address climate change and its effects. A recent research paper from professionals at Cornell University discusses ten ways AI can help in the fight against climate change. Those include creating low-carbon materials, making transportation more efficient, creating more tools to support individual changes to reduce carbon footprint, and designing more efficient electrical systems.

Artificial Intelligence can provide invaluable assistance in environment protection and resource conservation

One of AI’s other significant contributions is that it helps climate scientists build better prediction models so they can learn more about precisely how our actions are affecting the planet and what changes will be most effective. If you want to know about the benefits of green AI, click here.

Energy production

Greenhouse gases are, of course, produced in large part from our reliance on fossil fuels, which means a paradigm shift in energy production and use is in order if we’re to effectively address climate change. Wind farm tech is already taking hold, but there’s still much to be explored with solar power and how to efficiently store the energy generated from solar panels. Another promising line of investigation is nuclear power, which can produce carbon-free energy. We’re not there yet, but there are companies exploring how to do this safely, such as General Fusion in Canada.

Another type of tech in the works for energy production is the smart grid, which would be able to route energy efficiently and integrate renewable energy systems on a larger scale.

Climate change is a big problem, but there’s hope on the horizon in the form of new and emerging tech. Although different organizations predict different critical deadlines (2030 and 2050 being the two currently discussed), some are pushing for more aggressive action that uses available technology to its fullest extent. The Environmental Defense Fund, for instance, is calling for a 45% reduction in oil and gas methane emissions by 2025, which they claim is possible due to increased digitization in the industry. Technology, when harnessed, is one of the most powerful tools we have to successfully contend with the crisis we’re facing.

Waste-to-Energy Outlook for Jordan

4 Comments

A “waste crisis” is looming in Jordan with more than 2 million tons of municipal waste and 18,000 tons of industrial wastes being generated each year at an annual growth rate of 3 percent. Alarmingly, less than 5 per cent of solid waste is currently recycled in Jordan. These statistics call for a national master plan in order to reduce, manage and control waste management in the country. The main points to be considered are decentralized waste management, recycling strategy and use of modern waste management technologies. Currently there is no specific legal framework or national strategy for solid waste management in Jordan which is seriously hampering efforts to resolve waste management situation.

Waste can be converted into energy by conventional technologies (such as incineration, mass-burn, anaerobic digestion and landfill gas capture). Municipal solid waste can also be efficiently converted into energy and fuels by advanced thermal technologies, such as gasification and pyrolysis. Landfill gas capture projects represent an attractive opportunity for Jordan as huge landfills/dumpsites are present in all cities and towns.

A 1 MW pilot demonstration project using municipal solid waste (MSW) through landfill and biogas technology systems was constructed and commissioned in 2001.  The project was expanded in 2008 to about 4 MW.  Jordan plans to introduce about 40-50 MW waste energy power projects by 2020. However, biomass energy projects offer a low potential in Jordan because of the severe constraints on vegetation growth imposed by the arid climate. It has been estimated that animal and solid wastes in Jordan represent an energy potential of about 105 toe annually, but municipal solid waste represents a major fraction with a gross annual production rate of more than 2 million tons.

More than 80% of actual total manure generation is concentrated in 4 northern Governorates Al Zarqa, Amman, Al-Mafraq and Irbid. More than 80% of cattle manure is being produced in three northern Governorates Al-Zarqa, Al-Mafraq and Irbid. More than 80% of poultry manure production is located in 5 northern Governorates Amman, Irbid, Al-Zarqa, Al-Mafraq and Al-Karak. An exception is sheep manure. More than 90% of sheep manure is available in three Governorates Aqaba (40%), Al-Mafraq (25%) and Al-Zarqa (25%).

Conclusion

In Jordan, waste-to-energy can be applied at small-scale for heating/cooking purposes, or it can be used at a large-scale for power generation and industrial heating. Waste-to-energy can thus be adapted rural as well as or urban environments in the country, and utilized in domestic, commercial or industrial applications.

نصائح لتحسين جودة الهواء في الأماكن المغلقة

يعتبر تلوث الهواء في الأماكن المغلقة واحدا من أكبر المخاطر على الصحة العامة في جميع أنحاء العالم بسبب تزايد عدد الأمراض المرتبطة بالمباني. وجدت الدراسات أن تركيز الملوثات في الأماكن المغلقة هو أعلى بكثير في الداخل مما هي عليه في المناطق المفتوحة (الخارجية)، وتقارب النسبة مرتين إلى خمس مرات وفي بعض الأحيان مئة مرة أعلى من المستويات في المناطق المفتوحة (الخارجية). وبما أن معظم الناس يقضون 80٪ – 90٪ من حياتهم في الأماكن المغلقة، فإن جودة  الهواء في الأماكن المغلقة لها تأثير كبير على الاستدامة.

يؤثر انخفاض جودة الهواء في الأماكن المغلقة على نوعية حياة السكان في المباني، ويؤدي إلى زيادة المخاطر الصحية، وأيضا زيادة المسؤولية على مالك المبنى، حتى انه يقلل من إنتاجية السكان، ويقلل من قيمة المبنى المالية. وبإمكان سوء نوعية/جودة الهواء في الأماكن المغلقة ان يتسبب بحدوث بمرض “متلازمة  مرض المباني”، وهي حالة طبية مرتبطة بضعف الصحة والتغيب المزمن.

ويعود سوء نوعية الهواء في الأماكن المغلقة إلى عوامل عديدة منها على سبيل المثال لا الحصر: عدم ملائمة تصميم المباني، والتهوية غير الكافية، وتدفق الغازات من المركبات العضوية المتطايرة من الأثاث والسجاد والدهانات ومواد التنظيف ومن التنفس البشري. كما تساهم الذرات المتطايرة مثل ذرات القماش والغبار والعث والعفن والبكتيريا وحبوب اللقاح ورذاذ الطيور والحيوانات في سوء نوعية الهواء في الأماكن المغلقة. وتشمل المؤشرات المستخدمة لقياس نوعية الهواء في الأماكن المغلقة : الجسيمات الكلية والمركبات العضوية المتطايرة و الفورمالديهايد وثاني أكسيد الكربون وأول أكسيد الكربون والأوزون (O3) ودرجة حرارة الهواء والرطوبة النسبية. إن تركيز ثاني أكسيد الكربون في البيئة الداخلية أو الأماكن المغلقة هو مؤشر على وضع التهوية إن كانت كافية أم لا.

في منطقة الشرق الأوسط، يعيش معظم الناس في أماكن مغلقة في أجواء ذات هواء مكيّف. مع النمو السكاني السريع، وإزدياد عدد المركبات على الطريق، بالإضافة الى ارتفاع درجة الحرارة، وأنشطة البناء المتزايدة، والعواصف الرملية، فإن تركيز تلوث الهواء في المنطقة  يعد من بين أعلى المعدلات في جميع أنحاء العالم.

وحيث أن الهواء في البيئة الداخلية يعكس أيضا نوعية الهواء في المناطق المفتوحة ونسبة تلوثها فإن انتقال ملوثات الهواء الطلق إلى البيئة الداخلية  يمكن أن يعرض الساكنين فيها إلى أوضاع صحية خطيرة. وبالإضافة إلى ذلك، توجد العديد من مصادر التلوث في الأماكن المغلقة في مواد البناء، ومواد التنظيف، العفن والنمو البكتيري، والرذاذ المتطاير من المفروشات ، والتشطيب والأدوات أو المعدات.

نصائح لتحسين جودة الهواء في البيئة الداخلية

كما أسلفنا سابقا فإن نوعية الهواء في الأماكن المغلقة تتأثر بتركيز تلوث الهواء في الخارج، بالإضافة إلى المصادر الداخلية للتلوث، والتي تكون بالعادة من خصائص البناء أو من عادات سكان هذا المباني. ومن شأن التصميم المناسب للمبنى واستراتيجيات التحكم في النظام الميكانيكي وكذلك تغيير سلوك السكان أن تحسن نوعية الهواء في الأماكن المغلقة وكذلك الصحة والراحة ورفع الأداء والإنتاجية لدى سكان المباني. وللعلم هناك مجموعة من الاستراتيجيات المتبعه لتحسين نوعية الهواء في الأماكن المغلقة:

تصميم مناسب: تغليف البناء، اتجاه البناء، موقع دخول الهواء، وموقع أنظمة التهوية الميكانيكية ، كل هذه العوامل بإمكانها المساهمة في تحسين نوعية الهواء في الأماكن المغلقة. لذان يجب أخذها بعين الاعتبار خلال مرحلة تصميم المشاريع حتى تتم مراقبة المصدر الرئيسي للتلوث في المبنى بأكمله.
تصميم للتهوية الميكانيكية الشاملة: إذا تم تصميم نظام تهوية صحيح فإنه يمكن أن يؤمن إدخال وتوفير الهواء من الخارج بكميات كافية إلى المناطق المغلقة. يتم بالعادة اتباع معايير صناعية  مثل (ASHRAE Standard 62) في معظم أنظمة تقييم المباني الخضراء، لضمان نوعية الهواء في المناطق المغلقة.

في منطقة الشرق الأوسط، يعيش معظم الناس في أماكن مغلقة في أجواء ذات هواء مكيّف

استخدام التهوية ذات النمط المختلط: إن الدمج بين أنظمة التهوية الميكانيكية والطبيعية المستخدمة في المباني، مثل أنظمة التحكم الآلي في النوافذ والنوافذ القابلة للتشغيل، يمكنه أن يساعد في الحفاظ على جودة الهواء في الأماكن المغلقة.
إدارة نوعية الهواء أثناء البناء: خلال مرحلة البناء، يمكن لبعض البكتيريا أن تنمو على مواد البناء بسبب تعرضها للرطوبة، كما يمكن أن يتراكم الغبار والرذاذ بسهولة على مواد البناء إذا لم تكن محمية. لذلك يجب حماية نوعية الهواء من خلال حماية مواد البناء من الغبار والرطوبة.
استخدام مرشحات (فلاتر) الهواء عالية الكفاءة: هذه الفلاتر تقوم بمنع انتقال المركبات العضوية المتطايرة في الهواء الطلق، والغبار، وأنواع الرذاذ والأوزون إلى الأماكن الداخلية. إن استخدام مرشحات (فلاتر) عالية الجودة مثل MERV أثبت بانه الأكثر فعالية في تصفية الغبار في الهواء الطلق والملوثات العالقة.
الصيانه الدورية لمرشحات (فلاتر) HVAC (نظام التسخين، التهوية، وتبريد الهواء): إن استخدام المرشحات وعدم صيانتها وتنظيفها يمكن أن يسبب تهيج الحواس. ولذلك يجب عمل جدول صيانة دورية لهذه المرشحات (الفلاتر).
استخدام المواد ذات الانبعاثات المنخفضة: إن استخدام المواد التي تحتوي على مستوى منخفض من المركبات العضوية المتطايرة مثل السجاد الداخلي والأرضيات المطاطية والمواد الأخرى للأرضيات والسيراميك والأطراف والألواح الجبسية، أو استخدام مواد مانعة للتسرب والمواد اللاصقة الأخرى. هذا إضافة إلى استخدام المواد ذات المستوى المنخفض من الفورمالديهايد، يمكن أن تكون مفيدة.
إجراء عملية تنظيف شاملة للمباني: يساعد التنظيف الشامل للمباني قبل إشغالها بالسكان على التخلص من الملوثات الداخلية فيها ويساعد على استبدال الهواء الداخلي الملوث بالهواء النقي من الخارج.
برنامج التنظيف الأخضر: يكون باختيار مواد التنظيف المصنوعة من مواد منخفضة الانبعاثات وتحديد برنامج تنظيف أخضر للحد من التعرض للتلوث.
شاشات رصد ثاني أكسيد الكربون: تثبيت ودمج شاشات لمراقبة ثاني اكسيد الكربون في نظام التهوية  لتنظيم دخول الهواء النقي وفقا لطلب ساكني المباني. من خلال القيام بذلك، يمكن زيادة تدفق الهواء تلقائيا إذا زاد تركيز ثاني أكسيد الكربون عن مستوى محدد.

Leave a comment

Market enthusiasts have rightly said not everyone possesses the art of running a business but if you think you can be the one, the recent craze of online shopping has made it easier for you. Now setting up a business does not cost you your lifetime wealth, time, or even test your technical expertise. A recent marketing survey has shown that around 17.2% of the retail sales are composed of eCommerce selling accounts whereas online shopping in itself is expanding at the rate of 13.7%. So if you are looking for any motivation on how to set up an online store along with your brick and mortar business, now is the time.

steps to launch a sustainable online store

From creating a fusion of your own to selecting from the diverse range of businesses like selling products, dropshipping, warehousing, wholesaling, or even private labeling, eCommerce comes with a pool of options. To further simplify your needs in setting up an online store we have discussed five main steps to launch an ecological yet sustainably running online store.

1. Product/Niche Selection Accuracy

In order to begin with how to set up an online store, the foremost step is to find the product or niche which is the soul of your online selling platform. Here you must select the option which is rare or holds a significant touch of your individuality yet meets the demand and supply nature of the market in the longer run.

By choosing the term right niche or right product we mean that your selected option must show your individuality with the spice of uniqueness. As it will ultimately be the reason for your store’s ecological success.

2. Filling The Industry Gaps

Though when you will first step into the ocean of e-commerce retailing you would feel all the right niches are already taken. That’s totally a matter. With the usage of apt keyword research for niche selection, conduction of S.W.O.T. analysis, and efforts you can still find the unfulfilled gaps and demands of consumers. And yes, here you’ll rise and begin to serve as a consumer’s hero or their true savior.

In order to be more accurate with findings of industrial gaps you can hop on to:

  • Researching through social media the complaints requests or recommendations of consumers.
  • Hopping on google trends to contrast or compare the search volume of products.
  • Studying top sellers and finding out what their consumers ate missing or complaining about.

3. Forum Preferences

After the selection of a niche, the most crucial step is to identify which form of eCommerce platform you want in the search of how to set up an online store. To ease the confusion you can also go for eCommerce service providers or builders but before that select which form of eCommerce, you are willing to have. The options include;

  • Buying a domain with the hiring of professional developers to start it from scratch
  • Getting a domain with the option of an open-sourced eCommerce forum
  • Simply purchasing an established online platform

4. Designing The Interface

Though the idea of judging the book by its copper is considered shallow by many, in the case of how to set up an online store you must care about how the online store will give its first impression. That can only be created through designing a picture-perfect yet user-friendly website interface. Make sure your selected layout or theme is the actual depiction of your business’s nature whereas customized forms of layouts may offer you the following options to design the site;

  • Customization of text sizes
  • Addition of branded assets with high-resolution visuals
  • Color scheme configurations
  • Embedment of social media handles
  • Experimentation with listing of products with diverse and creative page layouts

5. Mastering Marketing

Wait, your struggle has just begun as the main task of promoting your site has arrived i.e. marketing the platform. The idea of promotion has become the easiest with the help of marketing your platform through different online channels, SEO ads as well as social networking advertisements.

Ways to Make Your Business Eco-Friendly

Ads highly help in increasing the visibility of your brand’s content as well as uplifting your revenues. Firstly, you can earn from running ad campaigns through google ad revenue. Secondly, you can generate bigger sales as the more the ads will be run around different sites the greater will be the visibility, and the higher will be the number of viewers who are your ultimate potential buyers.

With the higher recommendation of other digital marketing methodologies, you can also opt for blogging, online advertising, and running social media campaigns.

The Bottom Line

The scope of setting up an online business has been increasing with each passing hour with the uncanny indulgence of digitization in mundane lifestyles. Having said that 50% of the time of today’s generation is spent on mobile phones which is a good touchpoint to connect with a variety of interactions all around the funnel.

Setting up an online store is yet another example where one can easily generate higher profits especially if following ecological business practices. So don’t forget to go green and shine as bright as the queen!

هل تعاني من متلازمة الابنية المريضة

بالرغم من التقدم الذي أحرزه العالم في مجالي البيئة والصحة إلا أنه يواجه أزمة بيئية وصحية غير مسبوقة. ‏من المعروف أن الصحة هي من أغلى وأثمن ما يملك الإنسان, كما أنه من المعروف أن البيئة التي يعيش فيها الإنسان تؤثِّرعلى صحَّته بشكل مباشر وغير مباشر ,لذلك فإن لتنمية الوعي البيئي تأثيراً ملحوظاً على خلق وتعزيز السلوك البيئي الصحي السليم لدى الأفراد.

يعد المسكن من إحتياجات الإنسان الخمسة الضرورية كما صنفها الإسلام ,يمكن لتلوث عناصر البيئة مثل الهواء أن يؤدي إلى مشاكل صحية عديدة؛ فعلى سبيل المثال: يمكن للملوثات الموجودة في الهواء الداخلي في المنزل أن تسبب ظواهر مرضية مختلفة, منها " متلازمة المباني المريضة" .تشير الداراسات أن 30% من بنايات العالم هي بنايات مريضة ,لكن ما هي متلازمة المباني المريضة ؟

لقد تم التعرف على ظاهرة متلازمة المباني المريضة أو Sick Building Syndrome"" في السبيعنيات من القرن الماضي مع بدء إنتشار إستخدام المعدات الكهربائية . يستخدم مصطلح " متلازمة المباني المريضة " عندما تظهر مجموعة من الأعراض المشتركة على عدد من الأشخاص المتواجدين في داخل بناية معينة أو في جزء من البناية وتختفي هذه الأعراض في حال مغادرتها. ولقد وجد أن النساء يعانون منها أكثر من الرجال وهي أيضا موجودة بكثرة بين العاملين في داخل المكاتب والأماكن المغلقة مثل المدارس,أو المكتبات ,أو المتاحف, وبالرغم من التقدم العلمي في مجال الصحة البيئية إلا أن هذه الظاهرة لا زالت غير مفهومة.

كيف لي أن أعرف إذا كنت أعاني من SBS

يكون المبنى مريضاً ويسبب المرض لمستخدميه في حال  :

الأعراض المؤقتة والمتعلقة بالمدة التي قضاها المريض في بناية معينة أو في جزء منها.

إختفاء الأعراض في حال مغادرة المريض البناية.

موسمية الأعراض فهي تتعلق إما بالحرارة أو بالبرودة .

ظهور الأعراض على أكثر من واحد من زملاء العمل أو سكان المنزل .

الأسباب

لا يوجد سبب وحيد إنما تنتج هذه الظاهرة المرضية عن مجموعه من العوامل المرتبطة بآثار سمية للملوثات المتواجدة في داخل البناية وبتراكيز عالية .إن إغلاق النوافذ وإستخدام المكيفات الهوائية صيفاً أو إستخدام التدفئة المركزية أو مدافئ الغاز أو الكاز شتاءً يؤدي إلى سوء التهوية، وهذه أجواء ليست بصحية خاصة مع تواجد المدخنين في البيت.

كذلك فإن العديد من البنايات تعاني من ضعف التصميم أوالصيانة أو ضعف نظام التهوية وهوعادة المسبب الرئيسي للمشكلة,حيث أن ضعف نظام التهوية يؤدي إلى تراكم الملوثات المختلفة والذي بدوره يؤدي إلى رداءة  نوعية الهواء الداخلي في البناية مقارنة مع نوعية الهواء في خارجها حتى وإن كان موقع البناية في مكان يعاني بشدة من تلوث الهواء الخارجي, كما أن سوء التهوية يؤدي إلى إستنشاق المرضى لهذه السموم طوال الفترة التي يقضونها في داخل المبنى. ومن الجدير بالذكر أن التعرض لتركيزات منخفضة جداً من أنواع محددة من الملوثات الداخلية مثل المركبات العضوية المتطايرة تعمل في التسبب في أعراض المرض. من خلال الدراسات وجد أن  أسباب ظاهرة متلازمة المباني المريضة يمكن إيجازها فيما يلي  :

1. الملوثات الكيميائية :

1-1الملوثات الكيميائية الداخلية : مثل الأوزون الناتج عن آلالات الطابعة والتصوير, ودخان السجائر والغازات الصناعية المتصاعدة من السجاد والملابس ,إعادة طلاء البيت بأطلية محتوية على الرصاص, كما أن الإستخدام المتكرر للمنظفات الكيماوية أو المعطرات الصناعية يساهم في تلوث البيئة الداخلية للمنزل.

1-2  الملوثات الكيميائية الخارجية :  سخام السيارات.

2. العوامل الفيزيائية : ضعف التهوية, درجات الحرارة العالية , تغيير درجات الحرارة خلال اليوم , الرطوبة المنخفضة, الذبذابات,ضعف الإضاءة, الغبار ,إستخدام شاشات العرض لساعات طويلة.

3. العوامل البيولوجية : إن إنخفاض معايير النظافة تؤدي إلى تراكم الملوثات البيولوجية مثل حبوب اللقاح وحويصلات الفطريات وعث الغبار و العفن,والبكتيريا القادمة من المرحاض , والحشرات .

4. العوامل النفسية : الضغط والتوتر وضعف أخلاقيات الفريق العامل .

 

الأعراض

 من المهم ملاحظة أن مريض "متلازمة المباني المرضية" قد يعاني من بعض أو جميع الأعراض التالية :

  1. الصداع.
  2. الدوخة.
  3. صعوبة التركيز.
  4. تهيج الأنف والحنجرة والعيون .
  5. الغثيان .
  6. التعب العام و الإعياء.
  7. السعال.
  8. طفح جلدي .
  9. الحساسية للروائح.

 

مخاطر التعرض للبناء المريض

من المهم أن تكون قادراً على التعرف على أعراض SBS والتعامل معها بسرعة, حيث أن واحدة من القضايا الأكثر إشكالية والمتعلقة بـ SBS هو التشخيص الخاطئ وبالتالي عدم المعالجة والتي تؤدي إلى إزدياد حجم المشكلة, إذا واجهتك هذه الأعراض ولم تختفي حتى بعد مغادرة المبنى  فإن هذا قد يكون دليلاَ أنك تعاني من مرض يسمى ( Building-related illness( BRI

  • هل تعلم أنه يمكن أن يكون لـ  SBS  أثار نفسية طويلة المدى على شكل إكتئاب ,أو القلق أو حتى جنون العظمة؟

 

ما الذي يمكنني القيام به حيال SBS

تتلخص الحلول بتلافي المسببات ,عليك البدء بإتخاذ الإجراءات اللازمة إذا كنت تعتقد أن منزلك مريضاً،حيث أنك تحتاج إلى تحسين نوعية الهواء الداخلي, فبمجرد أن توقف بيتك عن إصدار هذه السموم فإن الأعراض المرضية ستتوقف تلقائياَ.أما على صعيد العمل, فإن متلازمة الأبنية المريضة تؤدي إلى إرتفاع غياب الموظف وإنخفاض كفاءته بالعمل , لذلك فإنه يجب التشاور مع زملائك لمعرفة ما إذا كانوا يعانون من نفس الأعراض, وفي حالة وجود الأعراض فإنه يجب تفحص المبنى من قبل خبير مؤهل,حيث أن ضعف تصميم المكاتب و ضعف صيانة أنظمة التهوية لها أن تضاعف الآثار الصحية السلبية للعوامل الملوثة. 

تمتلك الطبيعة أدوات فعالة جداً لتنظيف الهواء, حيث أن أشعة الشمس لها أثر العجب في تنظيف الهواء. لا بد من أن يكون هنالك منافذ كافية لدخول الشمس والهواء,فمن المهم جدا التركيز على التهوية الطبيعية الجيدة وبشكل دوري خلال اليوم حتى في أيام الشتاء القارصة البرودة ,كما أنه يجب الإهتمام بالنظافة العامة للبناية وهذا لا يعني الإسراف في إستخدام المنظفات إنما إستخدامها بإعتدال, أيضاً يجب التأكد من صحة إستخدام المواد المنظفة وتخزينها بعيدا عن أية مواد أخرى, كما يجب تفحص أنظمة التدفئة والتكييف والتبريد والتهوية وبشكل دوري.

لحسن الحظ أن هنالك بدائل طبيعية والتي تعمل على تنقية الهواء في الأماكن المغلقة مثل المنزل,حيث أنه يوجد أنواعاً من النباتات تعمل كمنقية للهواء الداخلي حيث أنها تقوم بإمتصاص المواد السامة من الجو. كما أن للنباتات تأثير ايجابي على الصحة النفسية فلقد أثبتت فعاليتها في زيادة التركيز والنشاط وفي التخفيف من الإرهاق والتوتر. ليس هذا فحسب, بل تفوق النباتات الخضراء شاشات الحماية أهميةً في التخفيف من تأثير الموجات الكهرومغناطيسية الضارة الصادرة عن الالكترونيات.مايلي قائمة بهذه النباتات لإختيار المناسب منها:

  1. زنبق السلام Peace Lily.
  2. Pothos Golden.
  3. أجلونيما Chinese Evergreen.
  4. نبتة الثعبان .Snake Plant
  5. الأقحوان الداخلي Daisies.
  6. أضاليا داخلية .Chrysanthemum
  7. Australian Umbrella Tree.
  8. الدارسينا Dracaena.
  9. Aloe Vera.
  10. السرخس Boston fern.

 

التوصيات

 يقضي الإنسان معظم يومه في داخل المباني أو البيئات المغلقة, ولقد أصبح الهواء الداخلي عرضة للتلوث مما يسبب أعراضا مرضية كما في " متلازمة المباني المريضة ", تسبب هذه المتلازمة الصداع والإجهاد الشديدين للمريض كما أن لها آثاراً سلبية واضحة على الصحة الجسدية والنفسية وتؤدي إلى تراجع الإنتاجية في العمل. تتلخص الحلول بتلافي المسببات ,كما تمتلك الطبيعة أدوات فعالة لتنقية الهواء, فالحرص على التهوية الطبيعية الجيدة حتى في فصل الشتاء مع ضرورة التأكد من دخول الأشعة الشمسية للمنزل بإعتدال له أثر العجب لحل المشكلة, أيضا يمكن إستخدام النباتات الطبيعية والتي من السهل العناية بها كمنقي طبيعي للهواء الداخلي ,كما أنه يجب عدم الإسراف في إستخدام المواد والمنظفات والمعطرات الكيماوية مع ضرورة مراعاة الحفاظ على معايير النظافة العالية.
