The management of MSW is going through a critical phase in India, due to the unavailability of suitable facilities to treat and dispose of the larger amount of MSW generated daily in metropolitan cities.
Various studies reveal that about 90% of MSW is disposed of unscientifically in open dumps and landfills, creating problems to public health and the environment. Hence there is need to handle MSW in a scientific way in order to reduce its impact on environment.
In urban areas, the major fraction of MSW is compostable materials (40–60%) which can be used to generate compost through processing. Hence there is a need to separate compostable material from the MSW.
Traditional (manual) or semi-automated techniques for sorting the MSW can recover low levels of separate materials from mixed municipal waste streams and mean considerable content going to landfill.
AEGIS offers Mechanized MSW Sorting System to convert complex and varied – even dirty – municipal solid waste streams into separated output which can be used for further processing like generating compost. The mechanized system has advantages of reduced labor cost, high efficiency and low material loss.
AEGIS conceptualized and commissioned first of its kind of MSW handling project for Coimbatore Municipal Corporation. The entire project was meant to treat 600 tons per day (TPD) of MSW in the city of Coimbatore in Tamil Nadu, India. The total waste was to be treated to produce compost and the rejects from the process to be disposed off in the existing landfill.
This project would result in reduction of greenhouse gas (GHG) emission due to avoidance of methane that would have been generated from the MSW disposed off in the existing landfill in the absence of the project activity.
This was the first project in India where it was proposed to install mechanized receiving and presorting station for 600 TPD of MSW. AEGIS conceptualized the mechanized system in close consultation with the client and their process consultants. Subsequently the system was installed and commissioned by AEGIS on turnkey basis.
The system supplied consisted of network of around 470 meters of special purpose, chain type belt conveyors and trommels with variable speed hydraulic drive and PLC based control system.
