Challenges of SWM

• Estimation

• Identification

• Collection

• Segregation

• Treatment

• Disposal

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

Current state

• 75-90% of waste generated is collected

• 60% is dumped at 60 known and unknown dumping sites around Bangalore

Composition of USW found at dumpsites (TIDE, 2000)

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

Our Objectives

• Physical survey of specific areas

• Map dumpsites

• Attempt to ascertain the source and age

Applications

• Provide current SWM status of the areas

• Can be fed to GIS

• Ground work for BBMP’s future SWM plans

Way point

Salient Feature of this way point

Approx. age of the

dumpImpact on environment

66, 67 &

68

Small dumpsite, signs claiming to de-silt

the lake bed and re-do the road7 – 28 days

De-silting is beneficial as it will check the overflowing of the

lake

74

Small dumpsites near settlements and

household waste7 – 28 days Degrading, mostly degrading organic waste and a little plastic

75Small dumpsite in a pit on the way

Within 7 days Plastic may cause asphyxiation in the animals that consume it

76Little accumulation at the road side

More than a weekPlastic will persist because its non-biodegradable and cause

soil degradation

77Plastic 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

79Plastic dispersed in a plantation area

(outside the map) More than 28 daysDisrupting 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

Salient Feature of this way point Approx. age of the dump Impact on environment

002Off 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

005Roadside 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 daysMalodor, unhygienic, may breed vectors, soil

degradation

008Construction debris, no garbage

More than 28 days Hindrance to plant growth

009Dustbin with a lot of trash outside it

Within 7 daysLack 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 daysPollution of the empty site, may cause choking of

animals if they ingest as it is mainly plastic waste

011Looked like a sorting area for plastic

waste Ongoing process No plant growth

012 – 014

Old dumpsites both sides of the road.

Garbage was mixed up and covered

in mudMore than 28 days

Seems to have stopped plant growth may have

increased toxicity of the soil

015Recycling/sorting unit in the

industrial area Ongoing process Beneficial

Bannerghatta Area (2nd two grids)

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

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

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

Thank you!
