Two new biogas plants for India
South Delhi Municipal Corporation (SDMC) is planning to install two biogas plants that will process cattle dung, according to The Times of India. They will be installed at Nangloi and Goyla Dairy Colony in Najafgarh and will each have a daily capacity of 200MT by March 2019.
A senior official told Times of India that private concessionaires are set to design, engineer, finance, construct commission, maintain and operate the plants for 20 years; they will then sell the electricity produced, as to recover the money. Additionally, the concessionaires will work alongside cattle owners and pay them for the use of their raw materials. The official says that this will “encourage the cattle owners to not dump the dung anywhere else.”
Approximately 170TPD (tonnes per day) of cattle dung is to be generated by The Nangli Colony and 50TPD by the Kakrola Dairy Colony. The Delhi Agricultural Marketing Board will also be providing 15TPD of food and vegetable waste.
SDMC has a one year plan to make Najafgarh a “zero-waste zone” through the installation of 10MT waste processing units and eight decentralised composting plants. Two demolition and construction waste plants, as well as vermi-composting to handle green waste, are to be set up by the company.
