A pilot project launched by the Confederation of Real Estate Developers Associations of India (CREDAI) in an apartment complex in the city has demonstrated that it does not take much to find a way out of the problem that has kept the Corporation on edge for over a decade. The ‘bio-bin’ system uses the aerobic microbial composting method to convert biodegradable waste into organic manure. The segregated waste collected from households is deposited in the aerated bins and treated with a microbial solution that triggers decomposition. CREDAI has employed a supervisor to operate and maintain the system that takes 20 to 30 days to convert the waste into manure.
