  6. 6. The Sada Zero system
  7. 7. The processSegregated resource in Collected in large bagshomeGoes to recycling factory Sold to scrap dealerWe no longer call it waste. We call it resource, because it isnow valuable recyclable or reusable material.
  8. 8. Segregation categoriesSeparation of home waste into:1. Wet waste – from kitchen, garden2. Dry resource. - Paper + cardboard - Plastic + metal - e-waste + glass
  9. 9. Collection methodWet waste – collected in dustbin, given to wastecollectors daily, as before1. Kitchen + garden waste2. Bio-medical waste (cotton, sanitary pads, condoms, syringes) wrapped in newspaper.Dry resource – collected in 3 different bags,given on weekends1. Bag 1- Plastic + metal2. Bag 2 - Paper + cardboard3. Bag 3 – e-waste + glass
  10. 10. Collection in apartment complexes1. Residents store segregated resource in their respective flats for whole week.2. On collection day morning they dump the resource in 3 drums.3. Drums are locked the whole week, only opened for a 1-hour window oncollection day.4. Dumping in drums is under supervison of Sada Zero volunteer, who notesdown the homes that are giving the resource.
  11. 11. The collection Gaadi Designed to be non-motorized, silent, non-polluting.Version 1 – too small Version 2 – too small, heavy Version 3 - big enough, still too heavy.
  12. 12. The destinationWet waste Same old dumpPaper & plastice-Waste & glass Ash recyclers
  13. 13. The people - collectorsSame team. Now called resource collectors (RCs).We thought they were the best people – they know thelocality, the process, places to sell the resource.They sell the resource, keep the whole money.Now earn Rs. 1000 a month each from sale ofresource.Dont have to wade throughmixed waste to recover Resource.They segregate the 3 categoriesinto 10.
  14. 14. The people - volunteersResidents of Sadashivanagar.Total around 30 people.Meet every alternate Tuesday.Distribute various tasks (enrolling new volunteers,performing skits to educate residents, coordinate withresource collectors..).
  15. 15. Starting on a new streetWe start segregation on a street whenwe have 3 volunteers for it (who need beresidents of the street).Enrol volunteers, train the volunteers.Map the homes – get house nos., names,mobile nos. on a mapping sheet.Do a presentation for the residents to explainthe Why and How of segregation.Distribute bags to homes.Decide on a date and time for weeklycollection.
  16. 16. Weekly collection systemThe day before the collection day, send SMS reminder tohomes to keep bags ready.Till a street hits 65 % Full segregation + bags at gate,volunteers walk with Gaadi on collection runs, note downhomes doing partial segregation, full seg., not at gate.Typical time 1 month.After this, volunteers do a maintenancewalk once a month to supply lost bags,record habitual not givers.Every weeks % for various streets isTracked as a graph, put up on internet.
  17. 17. Some rules we followVolunteers collect resource personally:- Erase stigma associated with garbage.- Social pressure on people to participate.- Get people involved in civic issues, by example.System must be self-sustaining, run by resourcecollectors. Only motivation is money from sale of resource– they keep 100 %.Should benefit resource collectorsin various ways – health, time, money.Take things 1 step at a time, in phases.Dont try to fix everything at once.
  18. 18. By now youre thinkingWhy arent these idiots doing anything about thewet waste ?We dont want to bite off more than we canchew.Phase 1 : Dry waste segregation in 7 streets(300 homes). Done.Phase 2 : Extend to 10 more streets. Doingnow.Phase 3 : Stop waste accumulation in streets,from homes and passers by.Phase 4 : Community compostingof wet waste, leaves.
  19. 19. Some challenges – ideas welcomeCollection % : Full segregation + bags at gate doesntseem to go beyond 70 %.Collectors : Still have to micro-manage them oncollection days. Issues with punctuality.Collection vehicle : Still experimenting, trying to make alight-weight, non-motorized, cheap vehicle.Space : Looking for public place to store collectionvehicle, do sorting, store unsold resource.
