Tiruchi Corporation has appointed a project management consultant to oversee and expedite the implementation of the upcoming bio-compressed natural gas (Bio-CNG) plant at the Ariyamangalam dump yard.According to officials, the consultant will monitor the project’s execution, ensure that quality standards are maintained during construction, and supervise the facility’s operations for three years after commissioning. A Chennai-based firm has been selected, and a sum of ₹48.49 lakh has been sanctioned for the purpose.The Bio-CNG plant was proposed in 2023 under the Swachh Bharat Mission 2.0 as part of the Corporation’s efforts to transform the decades-old Ariyamangalam dumpyard into a sustainable waste-processing hub. The project, estimated to cost ₹30.78 crore, is to be developed on four acres of reclaimed land within the dumpyard premises.Officials said the project was essential amid the rising fuel demand and the need for sustainable energy alternatives., and the appointment of a consultant would ensure the timely and efficient execution of the facility.Once operational, the facility would process 100 tonnes of biodegradable wet waste generated daily and convert it into compressed natural gas (CNG). The gas produced is expected to be used as fuel for vehicles.At present, the Corporation has outsourced the collection, segregation, transportation, and processing of municipal solid waste from all 65 wards to a private agency. Around 400 to 450 tonnes of solid waste are generated and collected every day across the city.While non-biodegradable dry waste is transported to the dumpyard for processing, segregated wet waste is handled at 36 micro-composting centres operated by the Corporation. The proposed Bio-CNG facility is expected to enhance the city’s waste-processing capacity by converting organic waste into a valuable energy resource.A contractor had been identified to implement the project under the public-private partnership (PPP) model. The plant would be developed under the Design, Build, Finance, Operate and Transfer (DBFOT) model, with preliminary work expected to commence shortly. Published - June 04, 2026 07:02 pm IST
