Kolkata: New Town Kolkata Development Authority (NKDA) has taken up a pilot project to produce manure from organic waste.
The solid waste composting plant was inaugurated by its chairman Debashis Sen on Thursday.
The wet waste will be collected from the community market of New Town Kolkata Development Authority (NKDA).
This is a situ-solid waste composting plant for conversion of organic/biodegradable waste to compost. The capacity of the plant is 1 MT/day. Continuous feeding of waste shall be done for six days and on the seventh day, the compost will be taken out. 1 MT of waste produces 100 kg of compost.
Once the waste is fed into the machine, there will not be any foul smell. Basically, the moisture from the waste is removed and after shredding it into small pieces, the process of composting is fueled by micro-organisms at some controlled temperature.
If successful, the project will be replicated in other markets in New Town. This will drastically reduce the carrying cost of organic waste to the trenching ground.
This is a part of the green city project by HIDCO. Several steps have been taken by HIDCO to increase the green cover in New Town. The waste water has been recycled and the water is being used to water the roadside trees.
Scarcity of land has put a serious threat to solid waste management throughout the globe. In Bengal, the problem is acute as most of the civic bodies do not have land to expand the trenching ground.
The Dhapa dumping ground was set up by the British and KMC needs more land to extend the dumping ground. But no additional land is available.
To cope with the problem, KMC has installed compactors all over the city. Compactors are being installed in the districts by the state Urban Development department.
