KCDC INVOLVES IN ECO-FRIENDLY TREATMENT OF CITY GARBAGE AND AGRICULTURE WASTE THROUGH PRODUCTION OF COMPOST BASED ORGANIC MANURE AND VERMIN COMPOST IN BENGALURU
WASTE PROCESSORS NEED BIO-FILTERS TO QUELL THE STINK
BENGALURU: Karnataka Compost Development Corporation is involved in Eco-friendly treatment of city garbage and agriculture waste through production of Compost based organic manure and vermin compost. Karnataka Compost Development Corporation is involved in Eco-friendly treatment of city garbage and agriculture waste through production of Compost based organic manure and vermin compost.? This Corporation was established in 1975 as one among thirteen such plants in India based on World Health Organizations technology as per the directions of Government of India to 22 States in accordance with the recommendation of Shri Sivaraman Committee constituted on the subject.
groups ready with quality compost do not know how to reach farmers
Shri.M.Venkatesh, Vice Chairman of KCDC, said, Due to the lack of a proper channel for collection and distribution, compost turned out by communities is being sold off at throwaway prices in 10 and 20 kgs available and plastic bags were in 40% control and compost plant at Kudlu in Bengaluru, subsidy from Rs.3000 to Rs 800, Rs 15 Crores fund from state Government but still it was in use.
An organic farming , with run Farm in Doddaballapura, was buying organic compost from a government outlet until realised that the quality was not up to the mark. That’s when chanced upon a gated community in in Town, which had surplus organic compost to offer. Buying the compost from them and does not mind.
Composting is not an easy task. Especially for communities that have very little or no support from the city corporation for setting up the infrastructure, facilitating daily operations or distributing it to the end user, the farmer.
This in turn leads to the farming community using cheap chemical alternatives. “The government needs to reduces subsidies on harmful chemical fertilisers and instead divert it towards organic composts to encourage more communities in the city to take this up as a social initiative,” says M.Venkatesh.
Due to the lack of a proper channel for collection and distribution, compost turned out by communities is being sold off at throwaway prices. “We have to sell our compost at Rs 2 a kg because we cannot store it or package it. The same quality compost in a retail store is available at Rs 20-40 a kg,” says a farmer , a waste champion who has been driving composting at in city since 2012.
To set up a sustainable composting unit, the initial processes involve sunk costs like setting up the right infrastructure, civil works and land. This is followed by monthly costs of running the facility which includes electricity, manpower and maintenance, points out which has been running its leaf-litter composting unit since 2011.
The 800-strong community produces 30 tonnes of leaf-litter a month and sells it under two categories (coarse compost at Rs 4 a kg and fine compost at Rs 8 a kg).
The composting unit has reached the self-sustaining mode after five years. Today, it sells compost worth Rs 50,000 per month through the use of social media and a network of buyers in the city.
“The BBMP has to help communities make composting a self-sustaining activity. It needs to incentivise it by buying back at subsidies rates, set up a proper channel of collecting and then distributing it to the farming community,”says.
BBMP’s joint commissioner (solid waste management) says that the volumes of compost from communities have not yet reached a large scale.
“If large communities which have bulk compost to sell come to us, we are more than willing to help them with marketing and distribution through the Karnataka Compost Development Corporation,” he said.
While all the seven waste processing units commissioned to tackle the city’s garbage are located close to residential localities, the civic corporation’s plans to use bio-filters to quell the bad odour emanating from them are far from ready . Biofiltration is the process by which pollutants that are released into the atmosphere are made to pass through a layer of micro-organisms that break them up and eliminate the odour.
The state government, under pressure to deal with the garbage crisis, spent Rs 440 crore to set up municipal solid waste management units at seven locations -Sigehalli, Kanahalli, Doddabidarakallu, Subbarayanapalya, Chikkanagamangala, Lingadheeranahalli and an extension of the Karnataka Compost Development Corporation (KCDC) unit near HSR Layout. They have a combined capacity to handle 4,600 tonne of waste every day . A backlash from HSR Layout residents over the bad smell prompted authorities to announce in last November that bio-filter systems would be installed in the unit.
As a pilot, four bio-filters were installed at the KCDC unit but are of little use without ducting. The civic body has issued a show-cause notice to the contractor responsible for the ducting work.
The initial deadline to get this up and running was February 18 but was extended to February 29, March 15, March 30 and April 25. “While the filters are ready , ducts to suck the odour remain undone. We are tracking the progress every day,” said BBMP’s special commissioner for solid waste management.
In fact, the BBMP’s expert committee on solid waste management has distanced from the bio-filter pilot. “We weren’t consulted about this,” committee member said.
Authorities claim that this is the first time a civic body is using bio-filters in municipal solid waste management. “The filters have been designed by the Indian Institute of Science Education and Research . “Once the KCDC pilot takes off successfully , bio-filters will be installed in the remaining six units.”
