Subsequently, seven waste processing units were setup on CM’s directions in Seegehalli, Kannahalli, Subbrayanapalya, Doddabidarakallu, Lingadeeranahlli, Chikkanagamangala, and KCDC.Waste generated by hotels and restaurants is now sent to the MSGP waste processing unit, which has a capacity of converting 4000 tonnes of waste into compost. Apart from the waste, Bengaluru also generates 3500 tonnes of garbage.But here’s the problem: according to BBMP’s Solid Waste Management Department, at present more than 3170 tonnes of compost is piled up in the waste processing units along with more than 19,200 tonnes of Refused Derived Fuel (RDF) which is a type of fuel produced by shredding and dehydrating solid-waste using waste converter technology. RDF consists largely of combustible components of municipal waste such as plastics, wooden piece, nylon materials and others.Speaking to Bfirst.in, Sarfaraz Khan, Joint Commissioner, BBMP Solid Waste Management, put the BBMP’s dilemma into perspective. “The BBMP has a stock of 3,170 tonnes of compost across all 7 processing units,” he said. “The BBMP charges Rs2,200 per tonne of compost but farmers purchase it during a particular season. Also, most of them want a quick and a better yield, hence they use pesticides rather than use compost. But now, on the directions of Union government, the state agriculture ministry has to purchase the compost by giving subsidy. This will be discussed in the cabinet meeting and will be cleared soon.”But Sarfaraz Khan admitted that Refused Derived Fuel was a major concern as it can catch fire. “The recent fire at the Kannahalli waste processing unit was due to the RFD,” he said. Earlier, cement factories in Karnataka used to purchase the RFD but now they are not doing so. The state government had called for a meeting with cement factory officials and tried convince them but nothing came out of it.”The joint commissioner said two cement manufacturers in Kalburgi had come forward to purchase RFD but backed out due to transportation cost. “We have now decided to identify quarry on the outskirts to stock the RDF,” he added.
