Plastics recycling. Asian workers with a pile of plastic pens which will be recycled for their Polyvinyl Chloride (PVC) content. Recycled PVC can be used to make new plastic items. The advantage of recycling is that PVC plastics release toxic chemicals if they are disposed of by being burnt or by being left in landfill waste dumps. Photographed in Mumbai (Bombay), India.
