Efficient way to turn waste into resource
A staggering amount of waste is generated every day in every town and city, and the local bodies are grappling with logistics for its disposal. The problem arises as the government and individuals fail to see waste as a potential source of energy and agricultural input in the form of manure.
The Bangalore Corporation, which recently made waste segregation mandatory at the household level, is showing the way for the rest of India. It is setting up 12 Nisargruna biogas plants across the city to convert biodegradable waste into methane and organic manure.
The Nisargruna biogas plant is based on technology developed by the Mumbai-based Bhabha Atomic Research Centre (BARC).
Such plants are being constructed at local levels too. Tata Consultancy Services (TCS) is planning to construct 4 tonnes a day capacity biodegradable waste conversion plant at its sprawling centre at Siruseri IT Park near Chennai. It already has similar plants operating at other locations. IIT Madras has already cleared a project for a plant with 1 tonne per day capacity. The Chennai Corporation recently initiated preliminary discussion with BARC.
