Abstract:     Solid Waste Management has become a major environmental issue. Bengaluru city had 56.86 lakhs of the population in 2001 (erstwhile Bengaluru Mahanagara Palike). The BBMP (Bruhat Bengaluru Mahanagara Palike) came into existence from 2007 with the merger of 7 City Municipal Councils, 1 Town Municipal Council and 110 villages into BMP and the administrative area increased from 200 sq kms to 800 sq kms. The present population of around 10 million accounting to a population density of 12500 persons/sq.km. The per capita MSW generated per day in Bengaluru is about 500 grams and MSW generation in the city has increased from 2500 tons per day to 4500 tons per day in a span of 10 years. In the present scenario, the urban waste is one of the major contributors to the urban environmental pollution and public Health. Municipal solid waste is one of the most challenging tasks being handled by Urban Local Bodies. The rapid urbanization, industrialization and changing lifestyles are complicating this issue even more. Bengaluru is facing this critical situation which has resulted in significant increase in Municipal Solid Waste generation in the last few years. This paper addresses the detail activity of the Solid waste management in BBMP, Bengaluru. BBMP is collecting MSW directly from households through the door to door collection mechanism. Segregation of MSW at the source is being promoted for effective handling and recycling of waste. The BBMP has taken up initiatives for streamwise handling of different categories of MSW like construction of Ward wise Dry Waste Collection Centers (to collect all types of dry waste with remuneration), Decentralized Wet Waste Processing Centers like Biomethanisation plants, Small Composting units, Green waste shredders for parks & palletisation plant for tender coconut shells & sugar cane waste etc. The BBMP is establishing composting plants to ensure 100% processing of its wet waste & also working on different strategies to make effective use of nonrecyclables. For effective handling, BBMP is in the process of separating the bulk waste generation stream which contributes to about 30% of MSW by facilitating the bulk waste generators to handle waste on their own.
