Aiming to achieve minimal waste, South Delhi along with West Delhi joins hands
Solid waste is rapidly becoming a major pollutant. Instead of mere disposal, solid waste may be considered a resource for reclamation or by-product manufacture. Overall systems for processing and recovery of Solid Waste may include three major component subsystems: size reduction, separation and recovery processes. There are various kinds of solid wastes but here we have ‘Municipal Solid Waste (MSW)’. South Delhi Municipal Corporation is aiming to achieve 100% processing of solid waste by 2021, for which it inaugurated another biomethanation plant of five metric tonne capacity at Dwarka Sector-14, costing around Rs.174 lakh.
The zero discharge plant with minimal requirement of water for cleaning can process biodegradable waste products to produce 250 kilowatts of electricity every day and 75-kilogram organic manure” said a senior SDMC official. The process goes this way: The waste (fuel) is burned, releasing heat. The heat turns water into steam in a boiler. The high-pressure steam turns the blades of a turbine generator to produce Electricity. An air pollution control system removes pollutants from the combustion gas before it is released through a smokestack. The South Corporation aims to achieve four such plants this year. One of them is already constructed at Punjabi Bagh and the second was inaugurated in Dwarka on Saturday, June 6th, 2019. The rest two are planned at Sarita Vihar and Vasant Kunj. These will be opened by July and August end, probably.
“The plant at Dwarka can be shifted to another site, anytime. The electricity generated by the plant will be fed to grid through net metering. Besides reducing the load on sanitary landfills, the plant will help reduce the emission of carbon dioxide and methane during the generation of electricity, considering there will be no incineration of material,” said a senior SDMC official. SDMC presently generates around 2,800 MT of waste daily, of which 2,600 MT is collected and disposed of. The existing waste-to-energy plant has the capacity to process 1,300 MT on a daily basis. We can clearly see how huge these efforts are to make our surroundings cleaner and healthier. Recycling and reusing waste products to generate electricity on a daily basis is something productive as well as smart.
