Introduction
Bengaluru
Scenario
Bengaluru scenario
• City generates 500MTday of MSW.
• An average of 0.5kg/day/capita with a population of about 10.8 billion.
• Facing problem due to existing disposal practices due to lack of
infrastructural facilities.
• Open dumping in the expanding city a serious problem to the structures
constructed on old dumping sites.
• Increasing population and growing IT sector local authorities are
struggling to provide a better SWM system.
• Bengaluru being a historical city have narrow streets and gully with high
population density
• Pockets of rural area amalgamated with developed city increased the
serious problem.
• The growth of vehicles on the road and traffic increased the problem.

BBMP
Present Waste
Management
Scenario
Present Waste
Management Scenario
• Bruhat Bengaluru Mahanaga Palike (BBMP), agency responsible for the
collection and disposal of solid waste.
• More effective and efficient approach BBMP is divided into different
administrative units
• 294Health wards under BBMP
• BBMP has two departments involved in solid waste management
1.Health Department
2.Engineering Department
• Health Department- collection, transport and disposal of solid waste
• Engineering Department-removal of construction and demolition waste,
provide technical and infrastructural facility to the above department.
3. Solid Waste
Generation
Solid Waste generation
▣ At present only 10% waste is recycled.
▣ Waste generation rate of Bengaluru city is 0.5kg/capita/day
▣ 500 metric tonnes of waste generated every day
▣ Acc. To studies it will increase by 10 times in next 20years
Characteristics of Municipal solid
Waste
▣ Biodegradable waste-55-60% of matter-decomposed to manure.
▣ Recyclable materials like paper, cardboard ,glass, metal ,plastic-16-25%.
▣ 15% of inert material goes to landfill.
▣ Characteristics of waste is changing with time.
▣ Due to city’s modest climate rate of decomposition is slow.

4. Collection
Collection
▣ Source segregation is still a concern but is picking up slowly with
awareness.
▣ BBMP manages 30% of MSW and 70% of MSW activity from source to
disposal.
▣ Collection carried out in 2 stages
□ First Stage-Primary collection in which solid waste is collected on
auto tippers and pushcart.
□ An auto tipper for every 10000 households, and a pushcart for
every 2000households
□ 2000Pourakarkikars re utilized(both BBMP and contractors)in the
door to door collection, street sweeping and transportation of
MSW.
□ Second Stage-waste collected from households brought to a
common point ,secondary location and then waste is transported
to landfill sites/compaction/recycling factories.
Collection
▣ BBMP assigned primary and secondary collection and transportation-
SHG’s(Self Help Groups) basically below poverty line women groups.
▣ Landfill sites operated by private sector on PPP(Public-Private
Partnership).
▣ Annually 250 cores spent on MSW(salaries of Pourakarkikars ,
contractors , tipping fees etc.)
5. Disposal
Disposal practices in Bengaluru
▣ City does not have any scientific treatment method facilities for waste
generated from industries around.
▣ Led to illegal and unauthorized dumping sites around the city.
▣ Waste generated by bulk generators(hotels , malls, markets, ) directly
collected and transported to treatment/disposal facilities.
▣ Treatment facilities developed around city and spread over entire zone.

pr=1.13#imgrc=WQfPU8oTJ3l6PM:
Sanitary Landfill sites
▣ BBMP can handle only 2100TDP of waste.
▣ Capacity of Mavalippura treatment facility-600TDP,KCDC(Karnataka
Composting Development Corporation)-300TDP and Tera -1500TDP
▣ For 100% waste processing of waste 6 new facilities sanctioned.
▣ These are wet waste composting plants-screening compost from
mixed MSW and provision to store non-compostsble/non-recyclable
materials.
▣ These materials used in co-incineration in cement industries/power
generations.
Illegal Dump Sites
▣ 60 dump sites
▣ Consists both municipal; and industrial waste from in and around city.
▣ BBMP and KSPCB(Karnataka State Pollution Control Board) have
closed the sites.
Transportation
push cart/auto-door to
door collection
waste collected at a
secondary point-trucks
Trucks transport to
waste disposal
sites/landfill
6. Issues
Major issues in transporting waste
▣ Open beds in trucks and tractors-spillage in transport-create nuisance.
▣ Loading of waste without protective gears-health hazards for workers.
▣ Secondary waste collection dumped on ground-no proper storage.
▣ Inadequate vehicles-not serviced properly.
▣ No proper maintenance of trucks/vehicles-out of service in short time.
7. Future options
Future options for Improper
Management of MSW
▣ Inappropriate plan for disposal of MSWM.
▣ Less expertise in modern techniques.
▣ Lack of technical and trained manpower.
▣ Lack of community manpower.
▣ Outdated management information system.
▣ Low budget
8. Suggestions
Suggestions for BBMP
▣ Construction and operation of properly planned sanitary
landfill through public private partnerships/private sector.
▣ Effective segregation of waste at source itself, and send the recyclable
separately to the respective processing units
▣ It is better to concentration on energy production through anaerobic
digestion and for land application rather than composting which is not
economical.

Integrated solid waste managemet of bangalore

  • 4. Bengaluru scenario • City generates 500MTday of MSW. • An average of 0.5kg/day/capita with a population of about 10.8 billion. • Facing problem due to existing disposal practices due to lack of infrastructural facilities. • Open dumping in the expanding city a serious problem to the structures constructed on old dumping sites. • Increasing population and growing IT sector local authorities are struggling to provide a better SWM system. • Bengaluru being a historical city have narrow streets and gully with high population density • Pockets of rural area amalgamated with developed city increased the serious problem. • The growth of vehicles on the road and traffic increased the problem.
  • 6. Present Waste Management Scenario • Bruhat Bengaluru Mahanaga Palike (BBMP), agency responsible for the collection and disposal of solid waste. • More effective and efficient approach BBMP is divided into different administrative units • 294Health wards under BBMP • BBMP has two departments involved in solid waste management 1.Health Department 2.Engineering Department • Health Department- collection, transport and disposal of solid waste • Engineering Department-removal of construction and demolition waste, provide technical and infrastructural facility to the above department.
  • 8. Solid Waste generation ▣ At present only 10% waste is recycled. ▣ Waste generation rate of Bengaluru city is 0.5kg/capita/day ▣ 500 metric tonnes of waste generated every day ▣ Acc. To studies it will increase by 10 times in next 20years
  • 9. Characteristics of Municipal solid Waste ▣ Biodegradable waste-55-60% of matter-decomposed to manure. ▣ Recyclable materials like paper, cardboard ,glass, metal ,plastic-16-25%. ▣ 15% of inert material goes to landfill. ▣ Characteristics of waste is changing with time. ▣ Due to city’s modest climate rate of decomposition is slow.

  • 12. Collection ▣ Source segregation is still a concern but is picking up slowly with awareness. ▣ BBMP manages 30% of MSW and 70% of MSW activity from source to disposal. ▣ Collection carried out in 2 stages □ First Stage-Primary collection in which solid waste is collected on auto tippers and pushcart. □ An auto tipper for every 10000 households, and a pushcart for every 2000households □ 2000Pourakarkikars re utilized(both BBMP and contractors)in the door to door collection, street sweeping and transportation of MSW. □ Second Stage-waste collected from households brought to a common point ,secondary location and then waste is transported to landfill sites/compaction/recycling factories.
  • 13. Collection ▣ BBMP assigned primary and secondary collection and transportation- SHG’s(Self Help Groups) basically below poverty line women groups. ▣ Landfill sites operated by private sector on PPP(Public-Private Partnership). ▣ Annually 250 cores spent on MSW(salaries of Pourakarkikars , contractors , tipping fees etc.)
  • 15. Disposal practices in Bengaluru ▣ City does not have any scientific treatment method facilities for waste generated from industries around. ▣ Led to illegal and unauthorized dumping sites around the city. ▣ Waste generated by bulk generators(hotels , malls, markets, ) directly collected and transported to treatment/disposal facilities. ▣ Treatment facilities developed around city and spread over entire zone.

  • 17. Sanitary Landfill sites ▣ BBMP can handle only 2100TDP of waste. ▣ Capacity of Mavalippura treatment facility-600TDP,KCDC(Karnataka Composting Development Corporation)-300TDP and Tera -1500TDP ▣ For 100% waste processing of waste 6 new facilities sanctioned. ▣ These are wet waste composting plants-screening compost from mixed MSW and provision to store non-compostsble/non-recyclable materials. ▣ These materials used in co-incineration in cement industries/power generations.
  • 18. Illegal Dump Sites ▣ 60 dump sites ▣ Consists both municipal; and industrial waste from in and around city. ▣ BBMP and KSPCB(Karnataka State Pollution Control Board) have closed the sites.
  • 19. Transportation push cart/auto-door to door collection waste collected at a secondary point-trucks Trucks transport to waste disposal sites/landfill
  • 21. Major issues in transporting waste ▣ Open beds in trucks and tractors-spillage in transport-create nuisance. ▣ Loading of waste without protective gears-health hazards for workers. ▣ Secondary waste collection dumped on ground-no proper storage. ▣ Inadequate vehicles-not serviced properly. ▣ No proper maintenance of trucks/vehicles-out of service in short time.
  • 23. Future options for Improper Management of MSW ▣ Inappropriate plan for disposal of MSWM. ▣ Less expertise in modern techniques. ▣ Lack of technical and trained manpower. ▣ Lack of community manpower. ▣ Outdated management information system. ▣ Low budget
  • 25. Suggestions for BBMP ▣ Construction and operation of properly planned sanitary landfill through public private partnerships/private sector. ▣ Effective segregation of waste at source itself, and send the recyclable separately to the respective processing units ▣ It is better to concentration on energy production through anaerobic digestion and for land application rather than composting which is not economical.
