NEW DELHI: The implementation of municipal solid waste management (MSWM) through the Public-Private Partnership (PPP) model in Indian cities will require the investment of $5 billion (around Rs 34,695 crore) per year, a joint report by industry chamber Assocham and British advisory multinational Ernst & Young (EY) said on Sunday. 

The study titled, "The big 'W' impact: effective urban waste management solutions in India" suggested the need for a comprehensive and forward-looking policy which can accelerate a shift towards a modern and healthy urban living.

MSWM is a fit case for the PPP model in India as urban local bodies are not financially and technically strong enough to manage solid waste, it said. The collection efficiency in urban areas of the country is poor at 70 per cent, and is still manual in nature, according to the report. It recommended the use of emerging technologies such as blockchain for waste management and sanitation.
