Observing that all machines at the city’s waste processing plant in Sector 25 have already completed their lifespan, the IIT-Roorkee has recommended setting up a modern 500 tonne per day (TPD) plant for dry and wet waste treatment.
“All machines are already 12 years old, which is practically the life of such machines. Both primary and secondary shredders are not in a working condition. The shredder is an essential component of waste processing,” said the report which has been submitted to the corporation.
What report says
“All machines are already 12 years old, which is practically the life of such machines. Both primary and secondary shredders are not in a working condition. The shredder is an essential component of waste processing,” said the report which has been submitted to the corporation.
“Though the existing scheme for solid waste processing is technically correct, it is only applicable to dry waste segregated at source. The plant should receive dry waste separated at source. Due to wet material, trommel screens are prone to blinding,” it further stated.
It has been observed that the plant was constructed in 2008 as per the municipal solid waste (MSW) 2000 guidelines. Now, it is mandatory to follow solid waste management (SWM) 2016 rules, which require segregated waste collection and processing.
“The best way is to set up a new modern 500 TPD plant for dry and wet garbage in the given plot. For wet waste stream, biological treatment will be required to meet the SWM 2016 rules. For dry or mixed waste, even after repairs/maintenance of existing machinery, shredder, trommels, etc., the existing plant will at best handle 60 to 65 TPD. Hence, if the corporation expects the plant to treat 200 TPD (40 per cent of 500 TPD), additional new equipment will be required,” the experts suggested.
Jaiprakash Associates Ltd had set up a municipal solid waste processing plant of 500 TPD, but it was recently taken over by the civic body on account of non-processing of the waste.
Since, the plant was not operated to its optimum capacity, the MC asked the IIT to conduct the site visit, assess the efficiency of processing machinery and suggest measures to improve the capacity of machines and the effectiveness of the plant.
