Pilot project proposed at Vembarpatti in Natham block

Bhabha Atomic Research Centre (BARC), in association with the District Rural Development Agency, has planned to make the villages in the district litter-free and environment-friendly, by setting up bio-methanation plants to generate gas and produce organic manure using bio-degradable waste.

A pilot project has been proposed at Vembarpatti village in Sanarpatti union in Natham block. Kallimandhayam in Oddanchatram block and Sivagiripatti in Thoppmpatti unions have also been identified for implementation of the plan at a later stage.

Explaining the project to The Hindu , J. Daniel Chellappa, senior scientist, BARC, Chennai, said Rs.17 lakh-20 lakh would be needed to commission a one-tonne-capacity bio-methanation plant, which could process biodegradable wastes such as kitchen waste, paper, grass, cattle dung and dry leaves and agricultural waste to generate power.

It would not produce any garbage or effluent, and it would provide high quality organic manure and methane gas. The manure, which had high nitrogen contents, was an excellent soil conditioner, he noted.

Only about 400 square feet of land was required for the plant, which could produce two cylinders of methane gas and 50 kg of organic manure a day. Gas and manure could be produced from the 19{+t}{+h}day of the plant’s operation, he added.

The biphasic bio-methanation technology had high potential to solve the solid waste problem.

Biodegradable waste could be put to productive use. BARC would offer the technology, help commission the plant, and train rural people in its operation and maintenance, he pointed out.

Biodegradable waste from markets, hotels, marriage halls and slaughter houses could be brought to the plant.

Mr.Chellappa said de-centralised waste management would cut transportation cost of waste to dumps.

BARC was making plants with the capacity varying from 100 kg to 25 tonnes, he added.

DRDA Project Officer M.C. Pandiarajan said the pilot project would be replicated in other panchayats in the district after its success.

The DRDA would select one village in each of the 14 unions for setting up this plant.

A district-level committee had been formed for the execution of the project. Villages that could generate less than one tonne of bio-degradable waste would be clubbed together to establish a plant, he added.
