To evaluate various technologies available for the onsite processing of wet waste by bulk generators and individual households, the Karnataka State Pollution Control Board (KSPCB) has formed a high-level technical committee consisting of both Bruhat Bengaluru Mahanagara Palike (BBMP) officials and KSPCB officials.
Since the wet waste is still not being effectively managed in the city, the committee has invited proposals from city based agencies that possess technologies for the onsite management of wet waste generated by bulk generators and individual households. The proposals will first be evaluated by the high level technical committee and a meeting would be called with the selected agencies to better understand how they will function.
According to the notification, the proposed technology used by the agencies should be implementable across a large domestic segment, and is in conformity with the Solid Waste Management Rules, 2016.
Dr Shanthi Tummala, one of the committee members, says, “The official notification asking for proposals from service providers with details about their technology being used is out. They will have to clarify in the proposal whether they are using the bio-methanisation process or the aerobic or anaerobic method. Once the proposal is accepted, they will have to apply and subsequently a meeting will be called for service providers where they will be given a chance to explain their methods. The committee will then evaluate them on details like what infrastructures will they require what quantity they can process per day and their previous case studies of installations.”
Once the committee is satisfied with the service provider, it will be approved. She says that this step was taken after a number of apartment complexes complained that even after paying high amounts to agencies; the quality of their compost from wet waste was poor. “We got to know a number of people are being cheated by some agencies who charge high amounts yet the quality of compost formed from the wet waste is as bad as ash and then these agencies would never be answerable. So we wanted to know how these agencies propose to function. Once selected, their details will be uploaded on the BBMP and KSPCB website so that people can approach them directly,” she says.
