Chennai:
The biodegradable waste of Chennai could soon be generated into power and manure with the launch of the pilot biomethanation plant in Pulianthope using Bhaba Atomic Research Center technology in the next 45 days.
The pilot plant, which was inspected by Barc scientists and Chennai Corporation officials, will have the capacity to convert two metric tonnes of biodegradable waste into 40 kv of power besides generating manure.
Speaking to Express, BARC scientist S P Kale, the brain behind the Nisarg Runa technology that is likely to be replicated in other parts of the country and state, said that the main aim is to ensure that biodegradable waste in kitchen should be processed and returned to the nature so that the next generation can keep enjoying the same natural richness being enjoyed today.
He said the plant will be using the food generated from hotels and bio-degradable wastes across the city. “It will be converted into a homogenized slurry before feeding into a pre-digester where it will undergo partial digestion of various organic acids,” he said.
“Then it will pass through main digester from where 80 to 100 metre cube of biogas will be produced. The slurry will be flitered and used as manure,” he said. It will also generate 160 to 170 kg of manure.
The initial investment is around Rs 40 lakh and it is likely that the project would be replicated in other parts of the city, he added.
Interestingly, Barc has set up 160 plants in various parts of the country. “Kerala and Maharashtra have 130 such plants,” said Kale.
Interestingly, the Barc scientist is totally against the incinerator technology which he feels is scientifically not advisable. “It is like short circuiting the nature,” he says.
The project is executed by Hubert Eurocare Systems (an associate of Hubert Stavoren B V Holland). J Jenish Jeyakumar, senior engineer of the firm said that the company’s proposal of nine more projects in the city is under consideration of Chennai Corporation.
