    • SOLID WASTE MANAGEMENT ANDSOLID WASTE MANAGEMENT AND ITS UTILISATIONITS UTILISATION THANK YOU Presented By:Presented By: Sarita SahooSarita Sahoo PAPRIPAPRI
    • 22 Classification of WasteClassification of Waste This includes :This includes : (a) Municipal Waste(a) Municipal Waste (b) Industrial Waste(b) Industrial Waste (c) Bio Medical Waste(c) Bio Medical Waste
    • Classification of Municipal waste Waste Bio degradable Non Bio degradable • Organic Waste e.g. Kitchen waste, Vegetable, fruits, flowers, leaf litter, paper & packaging materials • Recyclable waste e.g. Plastic, glass, metal, gutka pan masala packing material etc. • Others

    • TYPE OF LITTER GENERATED & TIME (APPROX) TAKEN TO DEGENERATE Type of litter Approximate time it takes to degenerate the litter Organic waste such as vegetable and fruit peels, leftover foodstuff, etc. a week or two. Paper 10–30 days Cotton cloth 2–5 months Wood 10–15 years Woolen items 1 year Tin, aluminium, and other metal items such as cans 100–500 years Plastic bags one million years? Glass bottles undetermined
    • INDIAN SCENARIO
    • 77 Table: Physical Characteristics of Municipal Solid Waste in Indian Cities Population range (In millions) Nitrogen as Total Nitrogen Phosphorus as P2O5 Potassium as K2O C/N Ratio Calorific Value Kcal/kg. 0.1 to 0.5 0.71 0.63 0.83 30.94 1009.89 0.5 to 1.0 0.66 0.56 0.69 21.13 900.61 1.0 to 2.0 0.64 0.82 0.72 23.68 980.05 2.0 to 5.0 0.56 0.69 0.78 22.45 907.18 5.0 & above 0.56 0.52 0.52 30.11 800.70 Composition of Waste • India produces 42.0 million tons of municipal solid waste annually at present. • Collection efficiency ranges between 50% to 90% of the solid waste generated.
    • GENERAL RECOMMENDATION FOR WASTE MANAGEMENT Possible Waste Management Options : • Waste Minimisation • Material Recycling • Waste Processing (Resource Recovery) • Waste Transformation • Scientific landfilling – Limited land availability is a constraint in Metro cities.
    • GENERAL RECOMMENDATION FOR WASTE MANAGEMENT Processing / Treatment should be : • Technically sound • Financially viable • Eco-friendly / Environmental friendly • Easy to operate & maintain by local community • Long term sustainability
    • VARIOUS TECHNOLOGY OPTIONS RECOMMENDED FOR WASTE PROCESSING TOWNS GENERATING GARBAGE (ORGANIC) UPTO 50 METRIC TONS / DAY(MT/DAY) = VERMI-COMPOSTING BETWEEN 50 MT & 500 MT / DAY = VERMI-COMPOSTING + MECHANICAL COMPOSTING MORE THAN 500 MT / DAY = MECHANICAL COMPOSTING + REFUSE DERIVED FUEL(RDF) FROM REJECTS KEEPING IN VIEW THE TYPE OF THE CITY (INDUSTRIAL OR NON- INDUSTRIAL) OR BIO-METHANATION

    • Activities from source to disposal Waste from household activities Segregation of waste at generation source Biodegradable Non Biodegradable Door to door collection Transport to local dustbin by trolley Waste transported to dumping site Biodegradable waste to ravines Ragpickers segregate recyclable material Transport to local dustbin by trolley Non-biodegradable waste to identified dumping ground Waste transported to storage site Plastic polybag sold to authorised recyclers Ragpickers segregate recyclable material Non-biodegradable waste to identified dumping ground
    • Segregation of waste at generation source
    • Transport to local dustbin by trolley
    • Bio - Non bio degradable waste dumped separately
    • UTILIZATION OFUTILIZATION OF ORGANIC WASTEORGANIC WASTE BYBY VERMI COMPOSTINGVERMI COMPOSTING 1818
    • 1919 BENEFITS OF COMPOSTING: • As much as 80% waste of low & middle income countries is compostible - increases overall waste diversion from final disposal. • Improves recycling and incineration operations by removing organic matter from the waste stream. • Produces a valuable soil amendment-integral to sustainable agriculture. • Promotes environmentally sound practices - reduction of methane generation at landfills. • Reduces waste transportation requirements. • Flexible implementation - Household efforts to large-scale facilities. • Requires very little capital.
