An Introduction to Materials Recovery Facility

By | | ,
7 Comments

A Material Recovery Facility (MRF) is a building to receive, sort, process and store recyclable materials to be shipped and marketed to end-users. A materials recovery facility accepts materials, whether source separated or mixed, and separates, processes and stores them for later use as raw materials for remanufacturing and reprocessing. The main function of the MRF is to maximize the quantity of recyclables processed, while producing materials that will generate the highest possible revenues in the market. MRFs can also function to process wastes into a feedstock for biological conversion or into a fuel source for the production of energy. … Continue reading →

Freshwater shortage in the MENA region is posing a serious threat to economic growth, social cohesion, peace and political stability. Furthermore, today’s freshwater usage does not account for its present and future availability but rather is based on sectoral and geographical competing consumption needs. To make matters worse, this already dire situation is being exacerbated by the rapidly changing climate. Climate change affects water resources by its profound impact on water quantity, variability, timing, form, and intensity of precipitation. The MENA region, in particular, is highly vulnerable to the disruptive climate change effects because countries within this region are unarguably … Continue reading →

Saudi Arabia, the epicenter of global oil industry, has been showing keen interest in solar energy in recent years. Saudi Arabia has one of the world’s highest solar irradiation in the world, estimated at approximately 2,200 thermal kWh of solar radiation per m2. The country is strategically located near the Sun Belt, in addition to plentiful availability of empty stretches of desert that may accommodate infrastructure for solar power projects. Vast deposits of sand can be used in the manufacture of silicon PV cells which makes Saudi Arabia an attractive location for solar industry. “The resource is stunning; land is … Continue reading →

Climate change is not only affecting the economies of Arab world but also having detrimental impacts on the very fabric of society, through threats to public health and livelihoods. Climate change in the Arab world is also exacerbating social inequalities, hitting the rural poor the hardest. This is not a reason for complacency amongst the wealthy urban classes. Basic humanitarianism aside, history suggests that physical hardships can breed wider unrest: a body of evidence suggests that poor harvests caused by a major Icelandic volcanic ash cloud in 1783 triggered no less an event that the French Revolution. Extreme weather events … Continue reading →

Trash Talk from Doha

On arriving a few years ago from a town in the UK that boasts a university course in waste management, and a very efficient weekly recyclable waste collection from our houses, I was a bit shocked, like many Europeans by how difficult it was to recycle in Doha. Having had the moral obligation to recycle drummed into me since I was quite young, I felt guilty throwing away all my waste into one bin, destined to fill up a huge smelly hole in the desert, where it would take a long time, if not forever to biodegrade. The Real Picture … Continue reading →

And that’s a crucial aspect of building a greener global culture, considering eight million pieces of plastic enter oceans every single day, posing significant danger to marine life. One problematic product billions of people use every single day is the humble car tyre. It’s so easy to take them for … Continue reading →
