PORVORIM: Minister for Waste Management Atanasio alias Babush Monseratte said that the Goa Waste Management Corporation (GWMC) intends to set up 25 TPD + 25 TPD, that is, 50 TPD bio methanation facility with ancillary facilities for treatment of wet waste at Sonsoddo dump site.
Replying to the question tabled by the Curtorim MLA Alexio Reginald Lourenco, Monseratte said that the 50TPD bio methanation facility could be set up after the completion of remediation of the legacy waste dump at Sonsoddo.
“Presently, the process of preparing a detailed project report (DPR) and estimates is initiated by GWMC.
As per the information received from Goa Waste Management Corporation (GWMC), setting up of 25 TPD, + 25 TPD Biodigester plant at the existing remediation dump site will be done by GWMC as a deposit work from Margao Municipal Council,” he said.
He said the features of the bio-digester plant will be decided during the preparation of a detailed project report.
“In contrast, the remediation of piled-up garbage inside the existing shed and outside the periphery of the shed will be done by GWMC from out of the annual grant-in-aid released by the Department of Science and Technology and Waste Management,” the minister says.
He further said that as per the information received from Goa Waste Management Corporation (GWMC), the Remediation of Sonsoddo legacy waste dumpsite is under process, and as per the tender floated by GWMC in 2019, the rate is Rs 1840.80 per Cubic Metre inclusive of all taxes.
“However, the piled-up waste inside the existing Sonsoddo shed as well as along the periphery of the shed will be remediated at the existing Sonsoddo legacy waste dump site and by the present remediation contractor of GWMC,” he stated.
Further, he added; also, the work will be considered under the present remediation tender and will be executed at the same quoted rate plus escalation in cost as per tender conditions.
“As a short-term and immediate measure, GWMC has prepared the tender for the work of “Operation and Maintenance of Sonsoddo Waste Management facility at Margao” for treatment of 30 TPD wet waste. Also, GWMC has prepared the estimates for “Refurbishment of existing Sonsoddo shed and external road development work”. Both proposals and projected estimates have been forwarded to the Margao Municipal Council on 16/06/2022 for obtaining Administrative and Financial approval for floating the tender, as the work will be executed by GWMC as deposit works,” he says.
Moreover, he said, as a long-term measure, GWMC is preparing DPR and estimation for 25 TPD+25 TPD Biodigester plant to be set up at the existing remediation dump site after the land is handed to GWMC after completion of remediation of Sonsoddo legacy waste. GWMC shall prepare DPR and estimates for the short-term as well as long-term solutions proposed and shall conduct the tendering procedure after MMC conveys the Administrative and Financial Approval. GWMC shall set up the required facilities and monitor/handhold MMC during the operational period of the proposed facilities.
“As per tender condition, the time of completion for remediation work including disposal of inerts and compost but excluding disposal of RDF (Refused Derived Fuel) is 24 months excluding monsoon which is upto March 2023 and time for completion of disposal of RDF is 36 months excluding monsoon which is upto January 2025. (#Monsoon period is considered from 15th May to 16th October). Presently the remediation works at Sonsoddo dumpsite are suspended due to rains and same shall be resumed post monsoon. However, GWMC intends to complete the remediation and disposal of RDF at the earliest and much before the tender period,” he said.
The RDF generated is sent to Cement Plants for co-processing. Disposal of RDF depends on the intake capacity of Cement plants.
