  3. 3. Classification • Domestic waste • Factory waste • Waste from oil factory • E-waste • Construction waste • Agricultural waste • Food processing waste • Bio-medical waste • Nuclear waste
  4. 4. Solid Waste
  5. 5.

  7. 7. SOURCES OF WASTE HOUSEHOLDS COMMERCE AND INDUSTRY
  8. 8. SOURCES OF WASTE Agriculture Fisheries
  9. 9. Solid Waste in India • 7.2 million tonnes of hazardous waste • One Sq. km of additional landfill area every-year • Rs 1600 crore for treatment & disposal of these wastes • In addition to this industries discharge about 150 million tonnes of high volume low hazard waste every year, which is mostly dumped on open low lying land areas. Source: Estimate of Ministry of Environment & Forest
  10. 10. Growth of Solid Waste In India • Waste is growing every year • In 1981-91, population of Mumbai increased from 8.2 million to 12.3 million • During the same period, municipal solid waste has grown from 3200 tonnes to 5355 tonne, an increase of 67% • Waste collection is very low for all Indian cities • City like Bangalore produces 2000 tonnes of waste per annum, the ever increasing waste has put pressure on hygienic condition of the city Source: The Energy & Resources Institute, New Delhi
  11. 11. Projections on Waste Generation In India
  12. 12. Waste Collection in India • Primarily by the city municipality :- - No gradation of waste product e.g. - bio-degradable, glasses, polybags, paper shreds etc. - Dumps these wastes to the city outskirts • Local raddiwala / kabadiwala (Rag pickers) :- - Collecting small iron pieces by magnets - Collecting glass bottles - Collecting paper for recycling
  13. 13. Disposal of solid wastes • Sanitary land filling • Shredding • Composting • Incineration • Barging it out into the Sea
  14. 14. Managing Waste Recycling Benefits of recycling :- - Reduce environmental degradation - Making money out of waste - Save energy that would have gone into waste handling & product manufacture Saving through recycling :- - Making paper from waste saves 50% energy - Every tonne of recycled glass saves energy equivalent to 100 litres of oil
  15. 15. Managing Waste • Reduce Waste :- - Reduce office paper waste - Improve product design to use less materials. - Redesign packaging to eliminate excess material while maintaining strength. - Work with customers to design and implement a packaging return program. - Switch to reusable transport containers.
  16. 16. Managing Waste Reuse :- - Reuse office furniture and supplies, such as interoffice envelopes, file folders, and paper. - Use durable towels, tablecloths, napkins, dishes, cups, and glasses. - Use incoming packaging materials for outgoing shipments. - Encourage employees to reuse office materials rather than purchase new ones.
  17. 17. Managing Waste Donate/Exchange :- - old books - old clothes - old computers - excess building materials - old equipment to local organizations
  18. 18. Hazardous / Toxic Waste & Dumping Site • Industrialized countries have waste management problems • Developed countries have strict environment regulation norms • Most attractive option for them- to dump into developing countries
  19. 19. Collection & Recycling of Waste Materials
  20. 20. Recycling not a solution to all problems ! - Recycling is not a solution to managing every kind of waste material - For many items recycling technologies are unavailable or unsafe - In some cases, cost of recycling is too high
  21. 21. Solution : More Profit With Zero Waste • Exchanging output that are considered waste • Waste of one could be input or raw material for others
  22. 22. Problems in Dealing With Solid Waste • Education • Collection of waste • Technological interventions • Institutions & regulatory framework • Absence of mandatory standards for waste reduction • Market action for waste reduction Source: The Energy & Resources Institute
  23. 23. • Effects our health • Affects our socio-economics condition • Affects our costal and marine environment • Affects our climate EFFECT OF WASTE IF NOT MANAGED WISELY
