On a daily basis, when the shops at the popular veggie market on Station Road in West Mambalam got shut, JCB loaders and tippers roll in to clear the vegetable waste — mainly, veggie, which were useless and got deteriorated.
At the present, a big portion of this veggie waste goes to Shri Shankarlal Sundarbai Shasun Jain College for Women situated in T. Nagar, to operate a biogas plant, which contributes in the direction of the working of the college kitchen.
The biogas project helped replacing 6 out of 90 LPG cylinders utilized on a monthly basis by the college kitchen.
Sundara Meena, a faculty member at the college told media, “Students and the staff of the college would pass through the market while heading towards the Mambalam railway station. The place is littered with garbage and is slippery. We decided to use biodegradable waste from here for our biogas plant, as we knew that the biodegradable waste generated on the college campus would not be sufficient. The gardener of the college goes to the market every day and collects the vegetable waste.”
The biogas plant provides benefits to both dealers at the local veggie market and the educational institution.
As per Monica Sethiya, a member of the ENACTUS chapter of the college, “The plant produces 2kg of bio-gas for every 50kg of bio-degradable waste fed into it. A by-product is the slurry that can be used as manure. Wastes that are acidic and fibre-rich should be avoided. This includes banana leaves and peels of citrus fruits. Among cooked food, dairy products should be avoided.”
For every 50 kg of recyclable leftover, which gets added into the biogas plant, it fabricates 2 kilograms of biogas, and the byproduct is utilized as dung.
As per Sanitary Officer C Arivuchelvam and Inspector N Sivakumar, who supervise solid waste management in the municipal limits, these wastes are eco-friendly and do not produce a filthy stench that typically arises because of waste deterioration.
“Residents have been requested to send biodegradable waste for six days, and on Wednesdays, they can send non-biodegradable waste through the conservancy workers. The details of the new system are being disseminated to residents through awareness programmes. With cooperation from residents and commercial establishments in the coming months, the recycling of these wastes will bring in more greenery in the municipal limits,” the report said.
