Q1. What are the difficulties associated with disposing of massive amounts of Municipal Solid Waste (MSW)? How can we safely remove it from our living environment? (250 Words 15 Mark)
Answer:
According to the CPCB report, only 68% of the MSW generated in the country is collected of which, 28% is treated by the municipal authorities. Thus, merely 19% of the total waste generated is currently treated in India.
CHALLENGES DISPOSING OF DISCARDED SOLID WASTES
- Unscientific landfill management: Occasional fires due to methane production deteriorates air quality and health
- Lack of proper collection procedure: Results in wastes being accumulated at each and every corner of the city over time.
- Inefficient segregation: The effectiveness of segregation is reasonably low as unorganised
sector segregates only valuable discarded constituents - Lack of technology: Results in inefficient processing of collected waste
- Under capacity of processing facilities: New Projects for garbage processing facilities are stuck and lack facilities for composting of wet waste.
- Failure of waste-to-energy projects: India is still struggling to make waste-to-energy projects a success story because of the absence of economically feasible technologies.
- Lack of space: Haphazard urbanisation reduced the availability of segregation space required for waste management.
- Lack of appropriate level funding: Due to the financial crunch ULBs do not have adequate infrastructure to provide suitable solutions
- The indifference of citizens: Some of them throws garbage and other waste on road and other public places
MEASURES TO REMOVE TOXIC WASTES SAFELY FROM OUR ENVIRONMENT
- Decentralization of waste management: In Vellore, waste is collected in a decentralised manner and composted naturally
- Bioremediation And Biomining: Uses microorganisms and plants to convert hazardous chemical and biological waste into inert materials
- Recycling: Convert Waste into useful materials such as making railway sleepers from waste plastics
- Scientific Capping: Capping Should be done with underground pits that have a good bottom and sideliners to prevent the escape of leachate and gases.
- Waste-to-energy projects in PPP mode: E.g.: Timarpur Okhla Municipal SWM Project, India’s 1st commercial waste-to-energy facility, converts 1/3rdDelhi garbage into electricity
WAYS FORWARD
- Kasturirangan Report recommends an Integrated approach Principle of (5Rs) Reduce, Reuse,
Recover, Recycle and Remanufacture - Community awareness & door-to-door collection using Resident Associations and NGOs Centralised processing Facilities: incineration, gasification, pyrolysis
- Decentralised processing facilities: biomethanation, vermicomposting
- Common Regional Sanitary Landfill Facility to reduce the land requirement
Though the government plays a significant role in waste management, it should also be the responsibility of every citizen to improve the quality of the environment around him/her. The need of the hour is scientific, sustainable and environment-friendly management of waste.
