BARC develops state-of-the-art kitchen waste management plant

MUMBAI, Apr 3/2004:

The Bhabha Atomic Research Centre (BARC) here has developed a state-of-the-art kitchen-waste disposal plant, which is perhaps the first of its kind in the world.
Named ‘Nisarga Runa’, the plant is already operational on an experimental basis at the BARC complex at Trombay and is being used to dispose the bio-waste generated in the canteens of the premier research organisation.

Talking to UNI, senior scientist with the nuclear agriculture and biotechnology division of the BARC Dr Sharad Kale, who played a major role in developing the plant, said two by-products are generated from the kitchen bio-waste. He said one by-product named ‘Nisarg Jyoti’ is a high quality methane gas that can be used for cooking and the other is weed-free fertilizer suitable for kitchen gardens and agriculture fields.

"Hence, we named the concept kitchen back to kitchen", Mr Kale said, adding that municipal bodies like the Brihanmumbai Municipal Corporation (BMC), the biggest civic body of Asia and the Navi Mumbai Municipal Corporation (NMMC) have shown keen interest in the project.
He said the plant would be a maintenance-free and will be beneficial for big societies, hotels and corporations.

Talking about the cost of the plant, Dr Kale said a plant with the capacity of processing five ton bio-waste per day could be set up merely with an investment of Rs six to seven lakh. He said the project, which can be set up in a 300 sq mts area, would break-even in two years time. Dr Kale said five to six cylinders of high quality methane gas could be generated from the plant and that can be used back for cooking food.

He said the fertilizer generated is weed-free and is a very good soil conditioner. Moreover, there is no presence of any heavy metals in the fertilizer.

Explaining the entire process, he said the bio-waste like leftover food is first mixed in a huge bin and made into liquid form by mixing it with water. Then the hot water used is heated through solar panels. For the entire process, no pumps are used and the plant is so designed that the entire material travels because of gravity, he added.

He said vermiculture is also a popular mode of disposal of bio-waste, but added that his model is better as vermiculture requires time and huge pits are needed. (UNI)
