Sustainable Processing of Municipal Solid Waste: ‘Waste to Wealth’

The CSIR-CMERI developed Municipal Solid Waste Processing Facility has not only helped achieving decentralized decimation of solid wastes, but has also helped create value-added end-products from abundantly available redundant stuffs such as dry leaves, dry grass etc. The MSW Processing Facility is developed for disposal of solid waste in a scientific way following the Solid Waste Management Rules (SWM) 2016 prescribed by Union Ministry of Environment, Forests and Climate Change (MoEF&CC), Govt. of India. The primary focus of CSIR-CMERI is to unburden the common households from the segregation responsibilities through advanced segregation techniques. The mechanized segregation system segregates solid waste into metallic waste (metal body, metal container etc.), biodegradable waste (foods, vegetables, fruits, grass etc.), non-biodegradable (plastics, packaging material, pouches, bottles etc.) & inert (glass, stones etc.) wastes. The bio-degradable component of the waste is decomposed in an anaerobic environment popularly known as bio-gasification. In this process biogas is liberated through conversion of organic matter. The biogas can be used as fuel for cooking purpose. The gas can also be utilized in gas engine for generation of electricity. The residual slurry from biogas plant is converted to compost in a natural process known as vermi-composting by introducing earthworms. The vermi-compost is utilized in organic farming.
