Source Separation - Case Study of a town Suryapet

Solid waste which is source separated can be easily handled as the separated waste streams can be directed to their respective treatment facilities like composting, recycling or waste to energy. However, source separation is not natural in the present day urban lifestyles; it requires effort. Success of source separation depends on education and environmental awareness among public, but these are not the sufficient conditions. Requirements for source separation and the probable causes for its failure in most cases can be understood with case studies, one such is the study of a town called Suryapet. I visited this town in South India as part of research for sustainable solutions to wastes in India; I selected this town because it was cited in numerous government and individual research reports for its successful composting practices.

Present situation in India

The latest table of Municipal Solid Waste (MSW) handling/processing techniques used in different Indian cities is present at the beginning of the blog, under the blog's header. Scroll down, play around the FILTER keys option for a variety of insights about the present situation of MSW management in India.
*************************************************************
Waste management was a house hold responsibility, but got transferred to centralized institutions due to shrinking living space and globalization. The Government of India (GOI) controls policy and regulations through Ministry of Environment and Forests (MOEF), Ministry of Urban Development (MOUD), Ministry of New and Renewable Energy (MNRE) and Central Pollution Control Board (CPCB). However, it is the responsibility of city administrations (municipal corporations) to enact these regulations, acting as a link between public and the government. GOI also provides the municipal corporations with tools like guides (National Master Plan for Development of Waste-to-Energy in India) and funding through initiatives like Jawaharlal Nehru National Urban Renewal Mission (JnNURM) to implement the regulations. Thus, municipalities are totally accountable to both public and the government and hold the most important role when it comes to waste management.
