Panaji: The Goa State Urban Development Agency (GSUDA) has come to the rescue of the Corporation of the City of Panaji (CCP), with an ‘approved proposal’ to set up a biodigester facility near the sewage treatment plant at Tonca.
The CCP is presently facing a problem of ‘inadequate mechanism’ in treating its wet waste.
The GSUDA has already taken government’s approval to set up Rs 1.50 crore worth biodigester plant, of 10-15 tonne capacity, funded under Corporate Social Responsibility, on a government land in Tonca.
The proposed plan is a part of the compliance with the NGT order, directing the state government to designate at least three major towns or cities in the state and at least three panchayats in each district as ‘model’ towns, and make them fully compliant, within next six months, with the Solid Waste Management Rules, 2016, and Plastic Waste Management Rules.
The city presently generates 28 tonne of wet waste, of which one truck of eight tonne is sent to Saligao plant and remaining 20 tonne of wet waste is processed at the organic waste management facility, located opposite Heera Petrol Pump at Patto, which is four times more than its handling capacity.
The plant would take at least two months to come into existence. And, during this time gap, the CCP has to adopt decentralised approach for waste management using economically feasible and proven technologies that support segregation and safe disposal of wet waste and also push for lasting behavioural change by involving the local community groups.
A biodigester (also known as a biogas plant) is a large tank wherein biogas is produced through the decomposition/breakdown of organic matter through a process called anaerobic digestion.
It is called a digester because organic material is eaten and digested by bacteria to produce biogas.
The biogas can be utilised for power generation, and with quality refinement to obtain biogas with 95 per cent methane content, which can be used as vehicle fuel.
