Integrated Municipal Solid Waste Disposal System (iMSWDS) for Bulk Waste Generators

Scientific management of Municipal Solid Waste has been one of the major thrust areas in urban India under the national flagship Mission Swachh Bharat Mission-Urban. In India, an estimated 62 million tonnes of Municipal Solid Waste is generated annually by 377 million citizens residing in urban areas. India’s urban population is expected to grow to 600 million by 2030 & to 814 million by 2050. Accordingly, India is set to generate 165 million tonnes of waste by 2030 and 436 million tonnes by 2050. As a result, the annual greenhouse gas emissions from Municipal Solid Waste is expected to go up to 41.09 million tonnes by 2030. This necessitates the importance of scientific solid waste management in today’s context.

Waste-to-energy is an option for sustainable solid waste management. It is the need of the hour to realise its potential as one of the most significant future renewable energy sources, which is economically viable and environmentally sustainable. For the developing countries where landfilling is the most preferred option for the management of solid waste, recycling of waste is seldom done, and hence, technological interventions for effective energy recovery from waste can be exploited to meet the increasing energy demands before all the fossil fuel reserves are depleted.

CSIR-CMERI has developed an integrated Municipal Solid Waste disposal system (i-MSWDS) for the disposal of solid waste in a scientific way in line with Solid Waste Management Rules (SWM) 2016 prescribed by the Union Ministry of Environment, Forests and Climate Change (MoEF&CC), Govt. of India. The CSIR-CMERI developed Decentralised Solid Waste Management Technology (DSWMT) has a design comprising of the following modules for bulk waste generators, i.e. Mechanized Segregation, Bio-Methanation, Composting, Briquetting, Pyrolysis and Plastic Agglomeration which tries and provides the solution for the management of every aspect of Solid Wastes.

Applications

• Urban Local Bodies (ULBs)
• Cantonment Board
• Railway and Defense Establishments
• Urban Agglomerations
• Gram Panchayat
• Industrial and Institutional Townships

The technology comprises of (a) Segregation plant for mechanized segregation of solid waste (100-125 kg/hr) (b) Biogas plant for producing biogas from organic fraction of solid waste (20 cum/day) & (c) Briquette Plant for making briquette from Agro Waste (50-60 kg/hr), d) Plastic Pyrolysis; e) Plastic Waste Re-Processing System.

Features:

• Complete disposal of solid waste in own premises and utilisation of value added products for circular economy,
• Discontinuation of transportation of waste to landfill sites thereby eliminating the chances of air, water and soil pollution,
• Mechanized segregation system to auto-segregate waste into bio-degradable waste, polymer waste, inert waste and metallic waste from mixed waste,
• Eco-friendly disposal of polymer waste through pyrolysis process,
• Re-processing of plastic waste to recycle used plastic scrap to produce plastic granules,
• Generation of biogas from organic waste and its utilization,
• Conversion of agro waste into briquette by mixing with the slurry of the biogas digester and utilization as fuel for cooking.
