Compost plant project gathers momentum

HUBBALLI: The twin cities will get compost plants soon. The Hubballi-Dharwad Municipal Corporation (HDMC) has expedited the process to construct the plants. While a 300 TPD capacity plant will come up in Hubballi, a 150 TPD capacity plant will be constructed in Dharwad.
HDMC sources told TOI that the twin cities generate 400 tonnes of solid waste per day. The waste processed by way of vermi-composting is 100 tonnes per year. The quantity of solid waste disposed at the dump site is 360 TPD. To address municipal solid waste management, it is establishing mechanical waste treatment and disposal facilities for treating mixed waste. The plant in Hubballi will be constructed beside the Karwar Road, while a 150 TPD plant will be constructed at Lakkamanhalli (Hosayallapura) in Dharwad. Sources said municipal waste primarily comprises of organic material such as yard waste, refuse from vegetable markets, food waste from hotels and restaurants, green and horticulture waste, cow dung and dairy waste. The organic content tends to decompose, leading to odour being emitted and pollution.

Compost can be produced by processing organic and biodegradable waste. Composting will reduce the volume of waste normally disposed in landfills, which will decrease harm to the environment. Mahesh Gowda, executive engineer (SWM), said that the plant in Hubballi will be built at an estimated cost of Rs 4.16 crore, while the one in Dharwad will be constructed at an estimated cost of Rs 2.89 crore. "A tender has been invited to build the compost plants. The plants will produce organic compost which can be used for agriculture. The compost will be supplied to farmers at a nominal price," he said.

HDMC sources said the annual report of the Karnataka State Pollution Control Board had highlighted the pathetic state of solid waste management in the twin cities. The report stated that the mixed waste is collected and transported directly to the dump yards. "A total 90% of the waste collected is transported to the dump site. No secondary storage facilities are available in the city. Scientific waste processing is not done by the authorities; instead, waste is dumped at a site," said the report.
