All that gas

Highlights By Garima Prasher The Bruhat Bengaluru Mahanagara Palike (BBMP) has a brand new scheme in the works to make use of organic municipal solid waste.

The Palike is all set to sign a memorandum of understanding (MoU) with an Indore-based company to set up BioCNG plants in the city under a publicprivate partnership. With a capacity of 500 tonne per day, two plants will be set up in Chikkanagamangala and Karnataka Compost Development Corporation premises in Bommanahalli in collaboration with EverEnviro Resource Management Private Ltd. The facilities will function based on the bio-methanation model.

 “EverEnviro will set up two plants of 500-tonne capacity each in BBMP limits. While we are waiting for the government’s approval, the plants are being set up to reduce fossil fuel consumption and promote CNG-based vehicles to reduce air pollution in the city. Needless to mention, it will also manage the city’s organic waste,” said BBMP special commissioner for solid waste management Dr Harish Kumar. The plants are expected to begin operations in 18 months.

The MoU will be signed soon; the BBMP has requested the company to expedite the process and start functioning within one year. With this, Palike has now decided to do away with its proposed waste-to-energy plants that were at various stages of development across the city. In its bid to solve the city’s garbage menace, the BBMP, had announced the establishment of six waste-to-energy units in and around the city in 2020. While a 14.5 MW plant in Kannahalli was expected to process 1,000 MT of mixed waste per day, a 2 MW unit in Doddabidarakallu was scheduled to convert 100 MT of mixed waste into energy every day.

BBMP had also proposed to partner with Firmgreen Enterprises and NEG to establish two different plants at Mavallipura to process 1,600 MT of mixed waste. While the former was expected to process 1,000 MT alone to produce compressed natural gas (CNG), the other 9 MW plant was proposed to convert 600 MT of waste to energy. Two more waste-to-energy units were expected to come up in Seegehalli and Lingenahalli. According to officials, the concept of generating energy from waste using conventional technology is an idea difficult to sell. While most of the companies that agreed to set up these plants do
