450 tonnes of mixed waste gets processed in this plant every day

 Waste is segregated using machines; wet waste composted

Workers in hats and boots stand beside a big machine, while a few stand in a corner sipping hot tea. Hard to believe that they are working inside a shed where 450 tonnes of garbage from the city is being segregated by a machine ahead of it being processing.

For the past 20 days, each day 450 tonnes of garbage has been sent to the waste processing plant at Chigaranahalli in Doddaballapur taluk. MSGP Infratech Pvt. Ltd. established the plant on 15 acres of land.

With deadline to stop sending garbage from the city to Mandur landfill round the corner, Bruhat Bangalore Mahanagara Palike (BBMP) is banking on this unit to take some load and set an example for other such units to emulate. By November-end, this unit will be able to process around 500 tonnes of waste every day, officials said.

According to project manager Pushkar, for the first time, composting is being done in a closed shed. Waste is segregated using machines and wet waste is then composted. The leachate is used to hasten the composting process. “Waste is composted on a concrete floor, so there is no leachate contamination. The waste that is not composted is first segregated manually. Plastic, glass and metals are recycled, while the remaining waste is converted into Retrieved Derived Fuel (RDF) that is sold to factories,” he said.

Mohan Lal, BBMP’s Assistant Executive Engineer, told The Hindu that a scientific landfill to dispose of the inert material was being set up. The unit has been established as per the Municipal Solid Waste Rules, 2000 and norms of the Karnataka State Pollution Control Board. There is no habitation in the three-km radius around the landfill.

BBMP sources said the unit has been set up at Chigaranahalli in just three months’ time. “Since the composting and all other activities happen inside a shed, there is no stench. The unit can be scaled up, if required, in future to process more waste,” sources added.

The Mysore City Corporation (MCC) is planning to activate the nine zero waste management units set up in different zones of the city soon to reduce pressure on its existing garbage treatment plant in Vidyaranyapuram here.

Mayor R. Lingappa, who led a delegation of councillors and officials of MCC to various zero waste management units here on Thursday as part of its initiative to create awareness about segregation of waste, said he had convened a meeting on Friday to discuss the modalities to start the units as soon as possible.

Mr. Lingappa said the city generates about 450 tonnes of waste every day and the existing garbage treatment plant can process barely 200 tonnes. “If all nine units start functioning, the pressure on the treatment plant at Vidyaranyapuram will come down,” he said.

Also, he said he will discuss the matter with councillors and officials to work out modalities for treating the waste generated in each ward within the particular zone.

M.K. Somashekar, Krishnaraja Assembly Constituency MLA, and D. Made Gowda, former MLC, were also part of the delegation that visited the zero waste management unit at Kumbarkoppal.

The unit collects around three tonnes of waste everyday and generates a revenue of Rs. 15,000 to Rs. 20,000 a moth by selling the manure at Rs. 600 a tractor load, said an MCC official.

 

Vadsar waste site yet to be scientifically shut

Vadsar waste site yet to be scientifically shut

 

VADODARA: The ugly sight of the officially discontinued municipal solid waste (MSW) disposal site at Vadsar greets one along with stench despite Vadodara Municipal Corporation (VMC) considering plans to close it scientifically. Over two years back, the VMC had considered developing the place as a garden or a similar recreational facility but precious little has been done.

The Vadsar site was in use since 1991 and its use was discontinued after remaining operational for nearly two decades. Even after it was closed, residents in the area and environmentalists complained about unauthorized dumping and environmental hazards that it presented. Environmentalists have time and again raised the issue of how the site was leading to ground as well as air pollution as garbage was burnt at the site.

In 2012, VMC had considered a scientific closure of the site by sealing its sides and top to ensure that water did not percolate in it. It was also proposed to put a layer of earth on the site and then develop a garden or a similar recreational facility there in a public-private partnership (PPP) mode.

The scientific closure would have lead to the civic body getting a large tract of land for use in place of the dumping site that one sees today. But the project was abandoned at the preliminary stage itself and little was heard about it subsequently. A senior VMC official said that while some firms with expertise in the field did come forward, it came to light that the costs of the closure were too high. "There were some reservations regarding the PPP mode as it would have amounted to giving the land to the private partner for use," said the official. He added that the civic body was still considering closing the site using some economical means.
