Context: The CSIR-CMERI developed Municipal Solid Waste Processing Facility has not only helped achieving Decentralised Decimation of Solid Wastes, but has also helped create value-added end-products from waste.
- The changing ecological scenarios requires special attention to address the issue of ‘Sustainable Processing of Municipal Solid Waste’.
- This CSIR-CMERI MSW Technology envisions a Zero-Landfill and a Zero Waste City in addition to developing Job-Creation opportunities.
Features of Municipal Solid Waste Processing Facility
- Bio-methanation Plant: CSIR-CMERI has started an innovative technology of producing the Biogas from grass and weeds and Vermi-composting of Slurry of the plant process.
- The Bio-Digestion process adopted has minimum pollution factor.
- The MSW facility has special disinfection capabilities to help Break the COVID Chain through UV-C Lights and Hot-Air Convection methods.
- The Smokeless Stove has also been developed to utilize these briquettes.
- Such stoves have the benefits of Reduction in import of LPG and reduction in pollution.
- Towards targeting a Zero landfill, the latest technology being used by Institute is Pyrolysis process wherein conversion of plastics into gas and fuel are done.
- Heavy oil, gas being used in pyrolysis helps in obtaining self-sustainability.
- Through Plasma Gasification Process also eco-friendly disposal of solid wastes is processed without formation and reformation of toxic dioxins and furans.
- Solid Waste Disposal using Plasma Arc convertes wastes into plasma state for proper disposal.
- Wealth out of waste: The residues generated having good carbon content are used in agriculture as fertilizer and non-usable are utilized to make bricks for construction purposes.
- The Solar energy technology, which can also feed the surplus Energy Supply onto a Mini-Grid.
- It can result in drastic reduction of expenditure related to Transportation Logistics and can help reductions in CO2 emissions, by reducing fossil fuel usage.
- It is the natural process of recycling organic matter, such as leaves and food scraps, into a valuable fertilizer that can enrich soil and plants.
- Fondly referred to by farmers as “black gold,” compost is rich in nutrients and can be used for gardening, horticulture, and agriculture.
Benefits of Composting
Reduces the Waste Stream
Cuts Methane Emissions From Landfills
Improves Soil Health and Lessens Erosion
- Reduces Personal Food Waste
Disadvantages of composting:
- The mixed nature of wastes in the current scenario can easily lead to infiltration of heavy metals into agricultural produce.
- Ineffective processing of Wastes are the root of all diseases as the dumped Landfills become the Contamination Hubs for Pathogens, Bacteria and Viruses.
- They also cause emission of Methane Gas, especially during the churning mechanisms deployed during Composting processes.
- Composting also does not yield impactful economic returns for the entrepreneurs.
