Puttenahalli Waste Management Program
Location : Puttenhalli Lake, Bengaluru
Supported By : ThoughtWorks Technologies India Pvt Ltd
Bangalore was once called the city of lakes . For centuries the Puttenahalli Lake in J.P. Nagar had been a pristine water body, playing a vital role in maintaining the fragile ecosystem of the neighbourhood. Like many other lakes in Bangalore, this one too fell prey to indiscriminate exploitation and neglect. The easy availability of packaged food and the ever increasing use of plastics has led to dumping of waste in and around the lake and burning of dry waste. The residents are unaware that they are breathing in deadly dioxins and furans being released by burning of plastic waste.
The Puttenahalli lake waste management project aims to address the problem of waste being dumped and burnt in and around the lake by residences and shops on the periphery. There are low-medium income housing colonies around the lake where no proper door-to-door collection of waste takes place. The objective of the project is to create awareness about the ill effects of burning of non-biodegradable waste and establish source segregation practices and regular door-to-door collection in the areas around the lake with the aim to minimize dumping of waste around the lake and remove the black spots.

Saahas has always believed in the decentralized waste management model and our program in Hubballi successfully showcase this. Under this program, a Dry Waste Collection Center has been setup in Hubballi where the dry waste collected from the local community is sorted. The center is run by an entrepreneur who sells the high value dry waste and sends the low-grade non-recyclable waste to the nearest cement factory.
While high value dry waste like paper, cardboard, PET bottles, metal cans are sold to scrap dealers for good rates, the low-grade waste like multi-layer food packaging (covers of chips, chocolates etc), shoes, textiles etc end up in landfills. This kind of waste, however, has a very high calorific value and can be used to generate energy through a process called coprocessing.
The collection staff is incentivized to bring the non-recyclable low-grade dry waste to the center and entrepreneur is incentivized to send it to the cement factories. This prevents 100% of the dry waste from being sent to the dumping grounds in and around the town.
