Recycling of PET Plastic Bottles

Like all other modern urban centers, the Middle East also faces challenges in environmental protection due to tremendous tonnage of plastic waste produced in different forms. The gross urban waste generation from Middle East countries exceeds 150 million tons per annum, out of which 10-15 percent is contributed by plastic wastes. The burgeoning population, growing consumption, and an increasing trend towards a “disposable” culture, is causing nightmares to municipal authorities across the region and beyond. Plastic consumption has grown at a tremendous rate over the past two decades as plastics now play an important role in all aspects of modern … Continue reading

The Significance of E-Waste Management

E-waste is the fastest growing waste stream, and its disposal is a major environmental concern in all parts of the world. More than 50 million tons of e-waste is generated every year with major fraction finding its way to landfills and dumpsites. E-waste comprises as much as 8% of the municipal solid waste stream in rich nations, such as those in GCC. Globally only 15 – 20 percent of e-waste is recycled while the rest is dumped into developing countries. However, in the Middle East, merely 5 percent of e-waste is sent to recycling facilities (which are located in Asia, … Continue reading

Solid Waste Management in the Middle East – Major Challenges

Middle East is one of the most prolific waste generating regions of the world. Solid waste management in the Middle East is bogged down by major challenges like lavish lifestyles, ineffective legislation, infrastructural roadblocks, indifferent public attitude and lack of environmental awareness. High standards of living are contributing to more generation of waste which when coupled with lack of waste collection and disposal facilities have transformed ‘trash’ into a liability. Major Hurdles The general perception towards waste is that of indifference and apathy. Waste is treated as ‘waste’ rather than as a ‘resource’. There is an urgent need to increase … Continue reading

Waste-to-Energy Outlook for the Middle East

High-income Middle Eastern countries like Saudi Arabia, UAE, Qatar, Bahrain and Kuwait are counted as world’s largest waste producers in terms of per capita waste generation which is more than 2kg per day in some countries. The urban waste generation from the region has now crossed 150 million tons per year which has forced policy-makers and urban planners to seriously look for sustainable waste management solutions, including recycling and waste-to-energy. Let us take a look at solid waste generation in major countries across the Middle East region: Country MSW Generation (million tons per annum) Saudi Arabia 15 United Arab Emirates … Continue reading

A Quick Glance at Composting Methods

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 lignin by fungi. Types of Composting There are 3 broad types of composting methods—anaerobic composting, aerobic composting, … Continue reading
