SDMC plans two biogas plants to process cow dung

NEW DELHI:

South Delhi Municipal Corporation

(SDMC) is planning to

install

two

biogas plants

at

Nangloi

and

Goyla Dairy Colony

in

Najafgarh

for processing

cattle dung

.

Under Swachh Bharat Mission, the corporation has finalised the tender to set up the plants with a daily capacity of 200MT each by March 2019. The work will be awarded by September-end. The move follows the Centre’s Solid Waste Management Rules 2016 that obliges a corporation to adopt a suitable process to process and disposal of cattle dung, and fruit and vegetable waste.

Each plant will cost around Rs 16 crore, said a senior official. “SDMC is expanding its waste processing, management and disposal capabilities.”

The private concessionaires will design, engineer, finance, construct, commission, operate and maintain the plants for 20 years. “The private concessionaires can sell the electricity produced from these plants to recover the money,” said the official.

The concessionaires will partner with cattle owners and pay them for the raw material. “This will also encourage the cattle owners to not dump the dung anywhere else. We have made them the third party in the tender conditions,” said the official.

The Nangli colony generates approximately 170TPD of cattle dung and Kakrola Dairy Colony around 50TPD. Delhi Agricultural Marketing Board will provide 15TPD of food and vegetable waste. “In many areas, the dairy waste is sometimes dumped in drains, triggering backflow,” added the official.

Under its one-year plan, SDMC wants to make Najafgarh a “zero-waste zone” by installing 10MT waste-processing units and eight decentralised composting plants. It will also set up two construction & demolition waste plants along with vermi-composting to treat green waste. SDMC has floated tender to build by March 2019 its second waste-to-energy plant at Tekhand with a daily capacity of 1,300MT.

SDMC generates around 2,800MT waste daily, out of which 2,600 MT is disposed of. The existing plant at Okhla has the capacity to process 1,300 MT waste daily. With the Tekhand plant, SDMC will be able to process 100% of its waste.
