BBMP Advances to natural gas production

Bengaluru: BBMP is ready to start the operation of waste processing units at full capacity. Along with this, it is also thinking of producing natural gas (CNG) to overcome the odor problem.

Waste processing has become a major problem in the city and BBMP is taking strict measures to find a solution to it. As directed by the High Court, wet waste processing will be carried out at full capacity in all the seven units from next week. Joint Commissioners of Zones are entrusted with the management of each unit.

Although about 2700 metric tons of wet waste is generated daily, it is able to be fully treated. The opposition of the locals, the people's representatives are demanding that they do not bring other people's garbage in their constituency. Thus, three out of 8 units were closed during the election. The Special Commissioner of Solid Waste Department has informed the Joint Commissioner that all the units should be operational in the next two weeks.

 Only about 1000 metric tonnes of wet waste is currently being processed in the processing units. The rest is landfilled as mixed waste. Processing plants are being started with the intention of almost stopping this. If fully operational it will be able to process more than 2200 metric tonnes of wet waste.

CNG production: 

As all seven processing units start up, there will be a smell. It takes 40 days for wet garbage to become compost. This causes some problems. Therefore, BBMP plans to convert these units into natural gas (CNG) generating units.

 The processing units are not able to process at the full capacity allotted to them in the present situation. Machines are losing their capabilities. Only 70% processing is possible. Thus, a plan has been drawn up to produce CNG in these units. This will get rid of all the problems you are experiencing now, including the smell. Also, the BBMP officials said that since CNG has a high demand and value, the corporation will also benefit financially.

GAIL India is going to set up a CNG plant from wet waste at Mandur, which is about to start. It has a capacity of 300 metric tons.

Don't bring garbage here: MLA Somasekhar

Waste should not be disposed of in Kumbalagode, Banashankari 6th phase including Doddabidarakallu, Kannalli, Seegehalli processing units under Yeshavantpur Assembly Constituency and other areas of the city, MLA ST. Somashekhar wrote a letter to BBMP Chief Commissioner.

If city legislators say that other garbage should not come to their constituencies, processing will not be possible. The High Court does not agree with this. Special commissioner of solid waste management Harish said that all the waste treatment units will be started.

Responsibility to the joint commissioner!

"Seegehalli and Subrayapallya processing units have not been functioning for a few years and the machines have broken down. They are said to be repaired and fully operational in the next two weeks. We have to process the wet garbage as there is a High Court order. All the powers have been given to the Joint Commissioner and they has to give the information to the High Court. Therefore, all the processing units will start working immediately,'' said Special Commissioner of BBMP Solid Waste Management Department. Dr. Harish Kumar.
