Biogas plant for Thiruvananthapuram market soon

According to reports, the Palayam market is likely to become self-reliant in terms of waste management with the commissioning of a high-capacity biogas plant capable of generating electricity in January. The work on the plant, which began in September, is nearing completion.

The rubble pack at the bottom layer has been made at a depth of 30cm. On the top of this layer, plain cement concrete (PCC) and reinforced concrete have been embedded at a depth of 15cm each. “We are now in the process of constructing the sidewall and the giant dome. The shaping of the dome requires some skilled work. We are hopeful that it can be completed soon,” said a Kerala state urban development programme (KSUDP) official, who is in charge of the project.

The bio-gas plant, the biggest among the ones being set up in city markets, will measure 9m in diameter and 5m in height. The digester of the plant will have a capacity to process two tonnes of waste per day. The biogas generated from the digester will be passed through a filter into the generator where it will be converted into electricity.

“Once the plant is ready, the electricity requirements of the market can be met with this plant. Also, managing the huge amount of waste will no longer be a problem for the corporation. The plant which will come up at Palayam will be much more advanced than the one currently at Sreekaryam,” chairman of welfare standing committee Palayam Rajan said.

The biogas plant at Palayam will be set up at a cost of Rs 26 lakh. The plant works on bio-methanization process where the organic waste is converted into methane, which in turn is converted into electricity.

The corporation is keen on getting the plant functional in the beginning of the New Year. The civic body has also initiated steps to set up similar decentralized waste treatment plants at Peroorkada, Kazhakootam and Manacaud markets. “The plant at Palayam will be the biggest since the amount of waste generated there is much higher than that produced in other markets,” Rajan said.

Corporation employees have been burying the waste generated from the market in pits so far. “We can’t go on like this forever. That is why we decided to speed up the work on the biogas plant at Palayam,” said a corporation official. The project is undertaken by a private NGO and is being supervised by KSUDP and the corporation.
