The Trichy Corporation has signed a memorandum of understanding (MoU) with a private cement factory to supply the city’s inert waste (non-recyclable and non-saleable) for reuse. The MoU is expected to help the corporation dispose of at least three metric tonnes of waste per day to the cement factory near Samayapuram where the waste shall be used as refuse-derived fuel (RDF) in furnaces. As the corporation’s dump yard in Ariyamangalam is undergoing biomining project to reclaim the 47.5 acre of land for better use, it is crucial for the local body to prevent fresh waste from heading there. The waste received from residents and commercial units across the city are being sent to 31 micro compost centres (MCC), where the degradable waste is converted as manure while non-biodegradable waste is sold to scrap dealers.
However, the third type of waste, inert waste including thermocol, rags and artificial leather find no takers. To solve the issue, the corporation roped in Dhandapani Cements (Maruti), a local cement manufacturer here to collect the inert waste for free on a daily basis for the next five years. “We do not have adequate space to stock the inert waste. Such MoUs with factories will help us utilise our land and human resources for better use,” a sanitary official said.
With the latest MoU, which is the third-of-its-kind, the civic body has increased the quantum of city’s inert waste being used as fuel from 17 MT to 20 MT per day. Besides the cement firm, the corporation, since February 2018 has been sending inert waste to Ultratech and Dalmia cement factories in Ariyalur. Waste having calorific value more than 3,500 KJ/Kg (amount of heat released) will only be accepted as RFD by the cement factories. “On rotational basis, inert waste collected and segregated at 31 MCCs will be sent to the cement factories through our trucks,” the official added. Corporation sources said that they will try to rope in more cement factories to utilise the waste.
