The fact that plastics make up less than one percent of municipal waste in Indian cities (as compared to eight percent of waste in Western Europe) is unlikely to mollify the municipal engineers who deal first-hand with the problems they cause.
They quote figures showing that while the manufacture of 1000 one litre plastic bottles consumes 57 percent less fuel than that of glass bottles, the manufacture of 1000 plastic bags consumes 32 percent less fuel than that of paper bags.
Of the types of plastics recycled in India, PVC (polyvinyl chloride) accounts for 45 percent, LDPE (low-density polyethene) for 25 percent, HDPE (high-density polyethlyene) for 20 percent, PP (polypropylene) for 7.6 percent and other polymers such as PS (polystyrene) for 2.4 percent.
Traditional materials currently being replaced by plastics include paper bags, leaf packaging for food in Africa and India, clay containers for food and water, and natural local building materials.
