Repetitive fire incidents at the old saturated Adharwadi dumping ground in Kalyan, and the pressure exerted by local residents to close the dump yard with immediate effect, have prompted the Kalyan Dombivli Municipal Corporation (KDMC) to undertake a new project to decompose waste.

The civic body will soon start spraying a solution on the waste at the dumping ground that is expected to help decompose the wet waste accumulated at the dumping ground and reduce it to 30% in 40 days.

Currently, 75- 80% of the waste accumulated at the dumping ground is wet waste and the remaining is dry waste.

According to the civic body, around 550 metric tonnes of waste is dumped in the dumping ground daily without any segregation.

“We have come across a method that can help decompose the wet waste by spraying a solution on it. We will initiate spraying soon once the solution is ready and check what the result is,” said Govind Bodke, commissioner, KDMC.

The KDMC has taken up the new method as a pilot project and if successful, will implement it in a wider scale.

In March, a major fire broke out in the Adharwadi dump yard, which sprawls across a 15-acre plot along the Ulhas creek nearby the Durgadi bridge in Kalyan (West).

The fire released thick smoke in the nearby area for almost a week, leading to suffocation among the residents. In the fire’s aftermath the residents took to the streets, demanding closure of the dump yard.

Although the civic body assured preventive measures to curb fires, on April 19, the dump yard caught fire again.

On April 23, Sreeniwas Ghanekar, a Right to Information (RTI) activist from Kalyan, who is demanding immediate closure of the dump yard, wrote to the KDMC commissioner. He explained that a project he had undertaken — zero garbage —at his residential complex in Kalyan, helps decompose wet waste.

Following this, Bodke on Thursday paid a visit to a zero garbage project undertaken by the residents of Om Shrikant Sadan, a residential building in Agra Road, Kalyan.

After his visit, Bodke decided to carry forward Ghanekar’s project as a pilot project to decompose the waste at the Adharwadi dumping ground.

Ghanekar said this method of decomposing the waste is very cheap (see box).

“One can prepare the solution repeatedly as per the need. There is no need to buy the culture again and again. It is a one-time investment and is very cheap. We have been doing this in our residential building for the past two years and it has been successful,” said Ghanekar.

The waste decomposer (culture) is provided by the National Centre of Organic Farming, Ghaziabad.

Ghanekar said, “I have been writing to the civic body chief for the past two years to undertake this method and see the results but I never received a feedback. This is the first time the civic body chief showed some interest and has agreed to take it as a pilot project.”

Another resident of the building Advait Bapat, 38, said, “None of our waste goes out as it is decomposed at the terrace of the building. Waste is collected from every household and taken to the terrace for decomposing. This project can be adopted by every building in the city.”
