Pimpri-Chinchwad, the twin city of Pune has a landfilling and waste dumping site, called as PCMC Moshi Kachara Depot, spread over 45 acres. For over 50 years, organic and inorganic waste was being dumped at this site. By 2011, the site had filled up completely and there was no space left to add any more waste. The place was a mess with thousands of crows and crores of flies flying over the dumping ground and were also spreading infections into human inhabitations around it.
The unbearable stench coming from dumping ground was felt from over 5 kms away and it was huge problem as well as health hazard for people staying in those areas. Residents from those areas were agitating day in and day out to have the dumping ground remove the dumping ground from its place.
BVG India Ltd was given the responsibility to manage the PCMC Moshi Kachara Depot in 2011 and changed the entire scenario that existed for over 50 years. We scientifically compacted the garbage in the dumping ground in such a way that it can now be used for the next 50 years.
Then we initiated a scientific capping project at the site, in which we built a 70-metre-tall layered hill. The layers of the hill consist of a 5 mm thick layer of plastic at the very bottom so that no leachate seeps into the ground. Over that we created layers of sand, organic waste, crushed stones, plastic, etc and covered it with mud and soil. We put in pipes through the layers to pull out the gas and drain out leachate.
After we took over the management of the depot, we emptied the entire area and processed the garbage. 60 to 70% of the garbage was organic waste, the remaining being plastic, metal, and glass. The organic waste was sent for processing to convert it in manure. We set up a plastic to fuel plant that processes all the plastic waste collected in the dumping ground and converts it to burnable fuel. Metals and glass were sent for recycling and remaining garbage was used for landfill.
Everyday approximately 800 tons of garbage is collected and brought to the dumping ground. Earlier, this entire 800 tons of garbage was sent to landfill. Today only 100 to 125 tons of garbage is sent to the landfill and the remaining entire garbage is processed. Therefore, this dumping ground site will be available to take in and process garbage for the next at least 70 years. Along with the plastic to fuel plant, we also set up a plant to prepare briquettes from burnable material or residue garbage, also called as RDF.
The PCMC Moshi Kachara Depot is the only garbage dumping ground in the country that prepares fuel from plastic, undertakes scientific capping and has received awards from the Government and is a feather in India’s cap.
