Working of a Modern Biogas Plant

Biogas plants are decentralized energy system that can lead to self-sufficiency in heat and power requirements, and at the same time reduces environmental pollution. A biogas plant stabilizes organic waste through natural biological process in the absence of air and transforms waste into biogas and biofertilizer. Such facilities are well-suited to wet organic material and are commonly used for treating biodegradable waste materials such as waste paper, grass clippings, leftover food, sewage and animal waste. The components of a modern biogas plant includes manure collection, anaerobic digester, effluent treatment plant, gas storage, and CHP or electricity generating equipment. Working of … Continue reading

Medical Wastes in GCC

There has been a growing awareness of the need for safe management of medical waste all over the world. Medical Waste are generated by all health sectors including hospitals, laboratories, diagnostic and research centers, dental and medical clinics, blood banks, mortuaries and autopsy centres, veterinary hospitals, industrial laboratories etc. Medical wastes which pose the greatest risk to human health are infectious waste (or hazardous medical waste) which constitutes 15 – 25 percent of total healthcare waste. Infectious wastes may include all waste items that are contaminated with or suspected of being contaminated with body fluids such as blood and blood products, used catheters … Continue reading

The Concept of Generalised Extended Producer Responsibility (GEPR)

The notion of Extended Producer Responsibility (EPR) has been part of the waste policy for a long time, particularly within the OECD countries. According to the OECD, EPR “aims to make producers responsible for the environmental impacts of their products throughout the product chain, from design to the post-consumer phase” [1]. EPR alleviates the burden of Public Administrations for managing end-of-life products, while -if properly designed- incentivising waste prevention and recycling. Current Limitations of EPR After years of implementation it can be argued that Extended Producer Responsibility has not in fact been so extended. Several limitations are common: a) producer … Continue reading

Top Tips to Make the Most of Your Scrap Metal Recycling

Scrap metal is a valuable commodity in high demand by small and large corporations. This is why many people have become interested in recycling scrap metal. It can be good for the environment because when the metals are recycled, they’re less likely to end up in landfills, thereby reducing environmental pollution. Moreover, recycling scrap metal can help conserve energy used in manufacturing. Instead of making new metals from scratch, people and businesses can use recycled ones, reducing energy consumption and reliance on new resources. Yet aside from the ones mentioned, scrap metal collection can be a great way to earn … Continue reading

This infographic will provide more insights into medical waste management situation in the Middle East.

Medical Waste Management in MENA

Healthcare sector in MENA region is growing at a very rapid pace, which in turn has led to tremendous increase in the quantity of medical waste generation by hospitals, clinics and other establishments. According to a recent Ministry of State for Environmental Affairs report, Egypt generated 28,300 tons of hazardous medical wastes in 2010. In the GCC region, more than 150 tons of medical waste is generated in GCC countries every day. Saudi Arabia leads the pack with daily healthcare waste generation of more than 80 tons. These figures are indicative of the magnitude of the problem faced by municipal authorities in … Continue reading

Introduction to Composting

The composting process is a complex interaction between the waste and the microorganisms within the waste. The microorganisms that carry out this process fall into three groups: bacteria, fungi, and actinomycetes. Actinomycetes are a form of fungi-like bacteria that break down organic matter. The first stage of the biological activity is the consumption of easily available sugars by bacteria, which causes a fast rise in temperature. The second stage involves bacteria and actinomycetes that cause cellulose breakdown. The last stage is concerned with the breakdown of the tougher lignins by fungi. Central solutions are exemplified by low-cost composting, as discussed … Continue reading

Trends in Recycling of EPS Foam

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. 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 … Continue reading

Waste Prevention in Middle East – Prospects and Challenges

The best way of dealing with waste, both economically and environmentally, is to avoid creating it in the first place. People and businesses that use resources wisely not only save money but also have much less impact on the environment. That is why waste prevention rightly occupies the top spot in the so-called “Waste Hierarchy” set out in EU and national waste legislation.  Waste prevention is about the way in which the products and services we all rely on are designed, made, bought and sold, used, consumed and disposed of. For example: Making products that are more durable, repairable, re-usable … Continue reading

Qatar is counted among the world’s fastest growing economies. Municipal solid waste management is one of the most serious challenges faced by this tiny Gulf nation on account of high population growth rate, urbanization, industrial growth and economic expansion. The country has one of the highest per capita waste generation rates worldwide which is as high as 1.8 kg per day. Qatar produces more than 2.5 million tons of municipal solid waste each year. Solid waste stream is mainly comprised of organic materials (around 60 percent) while the rest of the waste steam is made up of recyclables like glass, … Continue reading
