1 SOLID WASTE MANAGEMENT IN BANGALORE CITY, CHALLENGES AND POSSIBILITIES - A CASE STUDY WITH RESPECT TO SELECTED LOCATIONS Aparna Arun, Student Shashank Shrishrimal, Student Antony P. U. HOD, Zoology Christ University

2 Challenges of SWM Estimation Identification Collection Segregation Treatment Disposal

3 Challenges in our city Quantity of waste 3600 tons Lack of awareness/civic sense Throwing outside the bin Burning Lack of segregation Stagnation of untreated leachate Identification of illegal dumpsites

4

5 Current state 75-90% of waste generated is collected 60% is dumped at 60 known and unknown dumping sites around Bangalore

6

7 Composition of USW found at dumpsites (TIDE, 2000)

8 Possibilities Processing to be researched more Increased frequency of landfills Segregation of wastes Ground survey of dumpsites on the outskirts Biomethenation or vermicomposting of the organic waste

9 Our Objectives Physical survey of specific areas Map dumpsites Attempt to ascertain the source and age

10 Applications Provide current SWM status of the areas Can be fed to GIS Ground work for BBMP s future SWM plans

11 Bangalore City (with major roads)

12 Method and Material

13 Salient features for observations made in grids Way point No. Salient Feature of this way point Approx. age of the dump Impact on environment 66, 67 & 68 Small dumpsite, signs claiming to de-silt the lake bed and re-do the road 7 28 days De-silting is beneficial as it will check the overflowing of the lake 74 Small dumpsites near settlements and household waste 7 28 days Degrading, mostly degrading organic waste and a little plastic 75 Small dumpsite in a pit on the way Within 7 days Plastic may cause asphyxiation in the animals that consume it 76 Little accumulation at the road side More than a week Plastic will persist because its non-biodegradable and cause soil degradation 77 Plastic waste, roadside More than 28 days May spread to the surrounding areas 78 Huge dumpsite with burnt garbage dispersed all over the area, the borders of the dumpsite were raised which seemed to keep it hidden from the road More than 28 days, regularly burnt Release of toxic gases due to the burning of the garbage, degradation and choking of the soil, burning of plastic along with organic waste, destruction of habitat, loss of greenery 79 Plastic dispersed in a plantation area (outside the map) More than 28 days Disrupting the aesthetics, plastic waste is choking the soil, causing degradation 80 Chikka Tirupati Within 7 days Malodor (based on the number of animals) 81 No trash - 82 More than 28 days Dumping of garbage into water body

16 Salient features for observations made in grids Way point No. Salient Feature of this way point Approx. age of the dump Impact on environment 002 Off Bannerghatta main road to the left construction site Habitation loss 003 Dustbin with trash outside it 7 28 days Lack of civic sense 004 On the way to the zoo, roadside dump (mostly plastic) Within 7 days Lots of plastic, harmful for the environment 005 Roadside trash 7 28 days Chokes the growth of plants and is polluting the environment 006 Dustbin with trash outside it Within 7 days Lack of civic sense 007 Off the road, to the left in an empty plot on the way back from the zoo. Many pipelines were present. Garbage spread around More than 28 days Malodor, unhygienic, may breed vectors, soil degradation 008 Construction debris, no garbage More than 28 days Hindrance to plant growth 009 Dustbin with a lot of trash outside it Within 7 days Lack of civic sense, will be spread by cows, dogs and wild animals 010 On the Bannerghatta Anekal road. Small garbage dump between houses of a settlement Within 7 days Pollution of the empty site, may cause choking of animals if they ingest as it is mainly plastic waste 011 Looked like a sorting area for plastic waste Ongoing process No plant growth Old dumpsites both sides of the road. Garbage was mixed up and covered in mud More than 28 days Seems to have stopped plant growth may have increased toxicity of the soil 015 Recycling/sorting unit in the industrial area Ongoing process Beneficial

18 Bannerghatta Area (2 nd two grids)

19 What we discovered Rural less frequent but larger dumps, mostly organic Outside BBMP limits dug common pits Jigni industrial area seemed to have plastic sorting facilities

20 Conclusion Since most of the waste is organic, vermi-culture and biomethenation can be implemented successfully Identification of more area for land-filling is becoming a major need

21 Acknowledgements We would like to thank a few individuals without whom this project would not have been possible Dr. Antony P. U., HOD, Zoology at Christ University for giving us the opportunity to do this project Dr. Chanakya H. N. for mentoring us throughout the project Shwetmala for guiding us And the entire team at CST for their invaluable assistance

22 Thank you! Any questions?
