PVC, also known as Polyvinyl Chloride or Vinyl, is one of the most widely used plastics worldwide due to its chemical stability and durability. PVC products have an average lifetime of 30 years, with some reaching 50 or more years.  This means that more PVC products are reaching the end-of-life and entering the waste stream, and the amount is likely to increase significantly in the near future. The Middle East will ultimately have to deal with increased PVC waste as it is one of the markets expected to have high growth rates for PVC consumption, with developing countries in the … Continue reading →

The State of Qatar has one of the highest per capita waste generation rates worldwide. In 2012, Qatar generated 8,000 tons of solid waste daily (this is excluding construction and demolition waste which amounts to 20,000 tons additional waste per day).  This number is predicted to reach 19,000 tons/day in 2032, with an annual growth rate of roughly 4.2%.1  Most of these wastes end up in landfills – in 2012, more than 90% of Qatar’s solid waste were sent to landfills although the government is intensifying its efforts to reduce this amount.  This percentage is extremely high compared to many … Continue reading →
