Pimpri civic body gets 57 acres more for waste processing

Pune: The Pimpri-Chinchwad Municipal Corporation (PCMC) despite having 80 acres of garbage depot at Moshi has been permitted to have another 57 acres of land for waste processing and management by the state government. The PCMC will be implementing new waste disposal project on this 57 acres of land.

When the dumping of garbage at Urali is still a hot topic of discussion, the PCMC officials are saying that this plan is to have a waste processing and management site rather than another garbage dumping ground.

To decide on the land to be used for dumping the waste was to be done by December 2002, and to begin the project, the time PCMC had was till December 2003. It was then when the municipal corporation had finalised 57 acres of land at Punavale in survey number 24. Most of this land is actually owned by the state forest department.

But, in February 2005, this proposal was rejected by the standing committee and the corporation had to send the proposal to the state government. The decision of the state government only came last month and the corporation was informed that the standing committee decision was cancelled.

K Nagkumar, Chief of the Medical and health department said, "We will implement an environment friendly waste processing and management project at the site."

The PCMC now has to spend around 2.6 crore on land acquisition but the project will be funded by the Union government.

Biogas from sewage to produce electricity

N R Madhusudhan


BANGALORE: Managing sewage has given many a sleepless night to the officials of the Bangalore Water Supply and Sewerage Board (BWSSB), what with the city discharging 700 million litres of it daily.

After a dull public response put the board's plan of turning sewage into drinking water on the backburner, BWSSB is now setting its eyes on generation of biogas with the treatment of sewage.

“We are planning to use the biogas that would be produced from sewage for generating electricity. If all the sewage discharged in the city is used for this purpose, the current power crisis can be solved to some extent,” said a BWSSB official.

The BWSSB will construct 13 plants around the city to generate biogas from sewage.

Three of the plants will be constructed near the old sewage treatment plants.

The sewage will be directed into a specially designed bio-digester, which will facilitate the generation of biogas (mostly methane) from it. The biogas thus generated will be used as fuel for the generation of electricity, sources said.

Sewage becomes less toxic after biogas is generated as some of the poisonous gases are released in the process.

Thus, the residue can be used as manure.

After the process, the sewage water can be treated and used for non-potable purposes such as watering plants and washing clothes.

Tertiary-treated sewage is also considered safe for drinking after ultra-filtration, sources added.

The BWSSB had organised a seminar in June 2009 to create awareness about the generation of biogas from sewage, in which a delegation from the Swedish Energy Agency had also participated.

The idea of generating biogas from sewage had been discussed in the seminar.

BANGALORE: “Collecting waste unmixed from door to door, treating it as wealth, and recycling as much of it as possible is one of the best ways to minimise dumping problems, said Almitra H Patel, member, Supreme Court Committee for Solid Waste Management.

Presenting a paper on ‘Appropriate Urban Sanitation: Best Practices’ at a one-day workshop on ‘Sanitation, Governance and Technology Options’, she shared her experiences about zero dustbin and zero waste town project taken up in Suryapet and emphasised the need to collect waste unmixed, ‘wet’ every 24 hours and spoke about compost wet waste.

She said that keeping the waste unmixed even during transportation is a must and cities must collect only wet waste daily at doorstep for composting. Dry waste can be collected once or twice a week, she added.

Speaking about the solutions mentioned in the latest national policy ‘Municipal Solid Waste (Management and Handling) Rules 2000’ (MSW Rules), she explained the importance of procuring a waste processing and disposal site as per the MSW Rules. She said that it should be the immediate task for any city or town. “This applies to all towns and cities with over a population of over 20,000,” she added.
