Background:
Decentralized wet waste processing has the potential to reduce GHG emissions caused due to transportation of waste to centralized facilities, as well as ensures that the resources in the waste are recovered either in the form of compost or biogas. It also compares favorably in the capex and opex cost compared to large centralized systems. However, the non-availability of land, high manual labor and nascent technologies act as barriers to the successful implementation of decentralized solutions. Kasa Kendra is a community waste processing unit established by BBMP in the heart of Koramangala. The center has a dry waste collection center, a Kasa Rasa unit of Saahas, and a couple of biogas units

Objectives: 
The objective of this intervention is to expand the capacity of one of the biogas units so that more waste of the ward can be locally processed and the gas can be supplied to the nearby restaurants. Along with the expansion of capacity, new methods of purification, feeder systems, and digester designs have been tried out. Regular monitoring and comparison of expected to actual yield are being carried out to ensure that the plant operates as per the planned efficiency. An entrepreneur is successfully running this facility by charging the nearby restaurants for the gas supplied to them. 

A 300kg biogas unit was also set up at a community kitchen in Chennai. The kitchen is being run by a NGO which provides catering services to the offices near it. The waste from the kitchen is fed to the biogas plant and the gas generated is used in the kitchen, thus saving expenses towards LPG.
