Solid waste plant

  1. 1. SOLID WASTE PLANT • BY- • GAURAV SINGH • ME-09 • SRMSCET
  2. 2. What is waste?• Waste includes all items that people no longer have any use for, which they either intend to get rid of or have already discarded.• Additionally, wastes are such items which people are require to discard, for example by lay because of their hazardous properties.
  3. 3. EXAMPLES• household rubbish, sewage sludge, wastes from manufacturing activities, packaging items, discarded cars, old televisions, garden waste, old paint containers etc.
  4. 4. Types of wastes• Municipal Waste (including Household and Commercial)• Industrial waste (including manufacturing)• Hazardous Waste• Construction and Demolition Waste• Mining Waste
  5. 5. ...• Waste from Electrical and Electronic Equipment (WEEE)• Biodegradable Municipal Waste• Packaging Waste• End-of-Life Vehicles (ELVs) and Tyres• Agricultural Waste
  6. 6. ...• Waste from Electrical and Electronic Equipment (WEEE)• Biodegradable Municipal Waste• Packaging Waste• End-of-Life Vehicles (ELVs) and Tyres• Agricultural Waste
  7. 7. Basic contents
  8. 8. Facts and figures In INDIA, Solid waste – 30 million tonnes/year Liquid waste – 4400 millioncubicmetres/year Municipal solid waste- 0.25 to 0.66 kg/person/day (avg.45).
  9. 9. Method of waste treatment• Landfill- burying the waste.• Incineration- burning the waste to residue and gaseous products.• Energy recovery- using it as a mean to generate energy.
  10. 10. Technologies of waste recovery
  11. 11. Anaerobic digestion/ biomethanation1. anaerobic biodegradation of wastes.2. production of biogas & effluent.3. generation of power through turbines & engines.4. also used as soil conditioner & manure
  12. 12. Combustion/Incineration• Burning of wastes in presence of oxygen at high temperature (around 800ºC).• Generated heat(steam) is used in turbines to produce power.
  13. 13. Landfill Gas recovery• Organic fractions of waste slowly volatilizes and decomposes to produce landfill gases.• The gas contains a high percentage of methane (about 50%).• Used for direct heating/cooking applications.
  14. 14. Pyrolysis/Gasification• Organic material is heated in absence of air until the molecules thermally break down to become a gas comprising smaller molecules.• The gases produced by pyrolysis mainly comprise carbon monoxide (25%), hydrogen and hydrocarbons (15%), and carbon dioxide and nitrogen (60%).• Gases are used in I.C. engines & turbines.
