  5. 5. Classification of Wastes <ul><li>Solid waste- vegetable waste, kitchen waste, household waste etc. </li></ul><ul><li>E-waste- discarded electronic devices like computer, TV, music systems etc. </li></ul><ul><li>Liquid waste- water used for different industries e.g tanneries, distillaries, thermal power plants </li></ul><ul><li>Plastic waste- plastic bags, bottles, buckets etc. </li></ul><ul><li>Metal waste- unused metal sheet, metal scraps etc. </li></ul><ul><li>Nuclear waste- unused materials from nuclear power plants </li></ul>
  6. 6.

  7. 7. Growth of Solid Waste In India <ul><li>Waste is growing by leaps & bounds </li></ul><ul><li>In 1981-91, population of Mumbai increased from 8.2 million to 12.3 million </li></ul><ul><li>During the same period, municipal solid waste has grown from 3200 tonnes to 5355 tonne, an increase of 67% </li></ul><ul><li>Waste collection is very low for all Indian cities </li></ul><ul><li>City like Bangalore produces 2000 tonnes of waste per annum, the ever increasing waste has put pressure on hygienic condition of the city </li></ul><ul><li>Source: The Energy & Resources Institute, New Delhi </li></ul>
  8. 8. Waste Collection in India <ul><li>Primarily By The City Municipality </li></ul><ul><li>-No gradation of waste product eg bio-degradable, glasses, polybags, paper shreds etc </li></ul><ul><li>-Dumps these wastes to the city outskirts </li></ul><ul><li>Local Raddiwala / Kabadiwala (Rag Pickers) </li></ul><ul><li>-Collecting small iron pieces by magnets </li></ul><ul><li>-Collecting glass bottles </li></ul><ul><li>-Collecting paper for recycling </li></ul><ul><li>MCD- Sophisticated DWM (Delhi Waste Management) vehicle </li></ul>
  9. 9. How Solid Waste Affected Us In Recent Years? <ul><li>Cloudburst in Mumbai (2005) clogged the sewage line due to large no. of plastic bags </li></ul><ul><li>Blast in the Bhusan Steel factory at Noida, caused due to imported scrap from Iran </li></ul><ul><li>Reduction in the number of migratory birds due to consumption of contaminated foods </li></ul><ul><li>Stray animals dying on streets and farmland due to consumption of plastic bags, which blocks the food movement in their stomach </li></ul>
  10. 10. Hazardous / Toxic Waste & Dumping Site <ul><li>Industrialized countries have waste management problems </li></ul><ul><li>Developed countries have strict environment regulation norms </li></ul><ul><li>Most attractive option for them- to dump into developing countries </li></ul>

  13. 13. Collection & Recycling of Waste Materials
  14. 14. Managing Waste <ul><li>Recycling: Processing of a waste item into usable forms. </li></ul><ul><li>Benefits Of Recycling: </li></ul><ul><li>-Reduce environmental degradation </li></ul><ul><li>-Making money out of waste </li></ul><ul><li>-Save energy that would have gone into waste handling & product manufacture </li></ul><ul><li>Saving Through Recycling: </li></ul><ul><li>-Making paper from waste saves 50% energy </li></ul><ul><li>-Every tonne of recycled glass saves energy equivalent to 100 liters of oil </li></ul>
  15. 15. Recycling Not A Solution To All Problems! <ul><li>Recycling is not a solution to managing every kind of waste material </li></ul><ul><li>For many items recycling technologies are unavailable or unsafe </li></ul><ul><li>In some cases, cost of recycling is too high. </li></ul>
  16. 16. Solution: More Profit With Zero Waste <ul><li>Exchanging output that are considered waste </li></ul><ul><li>Waste of one could be input or raw material for others </li></ul><ul><li>Evolving a closed system- matter & energy circulate within </li></ul><ul><li>System was not designed to be so </li></ul><ul><li>The system of exchange evolved in 10 years </li></ul>
  17. 17. Problems In Dealing With Solid Waste <ul><li>Education & voluntary compliance </li></ul><ul><li>Collection of waste </li></ul><ul><li>Technological interventions </li></ul><ul><li>Institutions & regulatory framework </li></ul><ul><li>Absence of mandatory standards for waste reduction </li></ul><ul><li>Market action for waste reduction </li></ul><ul><li>Source: The Energy & Resources Institute </li></ul>
