Outlines
🏗️ Goa's Second Integrated Waste Treatment Facility and Financial Assistance
The paragraph introduces Goa's second Integrated Waste Treatment facility in Kakura, South Goa, with a capacity of 100 tons per day. The project, supported by financial assistance from NABARD through the Rural Infrastructure Development Fund (RIDF), aims to improve waste management. The RIDF, launched in 1995-96, initially focused on infrastructure for irrigation and flood protection but has expanded to include waste management, recognizing its importance for rural development. The Kakura site was previously a waste dump, remediated in 2019, clearing 25,000 cubic meters of waste for this new facility.
♻️ Sustainable Waste Processing for 30 Local Bodies
This paragraph explains how the Kakura facility handles waste from around 30 local bodies, including four municipalities. The facility employs an integrated treatment approach, with separate processing lines for wet and dry waste. Waste is brought to the facility by trucks, weighed, and processed through conveyors. Waste is sorted into recyclable fractions, which are then weighed, stored, and sent for recycling. Light fractions are sent to the RDF storage area for co-processing in cement companies. The facility adopts advanced segregation techniques to maximize recycling and resource recovery.
🌱 Organic Waste Treatment and Biogas Generation
This paragraph details the treatment of wet waste at the Kakura facility. Wet waste is homogenized by screw conveyors and processed through an organic extrusion press. The organic pulp is transferred to a thermophilic digester, where it ferments and generates biogas. The biogas is scrubbed to remove H2S and used in biogas engines with an 800-kilowatt capacity. Excess biogas is flared off, and the generated electricity powers the facility, with the surplus exported to the grid. The remaining sludge undergoes dewatering and drying in solar sheds, producing high-quality compost.
🛠️ Final Waste Disposal and Environmental Safeguards
This section covers the final steps in waste management. The residual waste, less than 10% of the total, is disposed of in a scientifically constructed landfill, lined with HDPE and geotextile materials. Effluent from the facility is treated in an Effluent Treatment Plant (ETP) to reduce pollution before reuse. The treated water is used for gardening and fire safety. Odor control is maintained through biofilters, and air quality in sorting stations is regulated with air filters and cooling systems. The entire facility is monitored through a SCADA-based system and equipped with safety features, including a firefighting system.
🌍 Positive Environmental and Community Impact
This final paragraph highlights the outputs of the Kakura Solid Waste Management Facility, which include electricity, compost, recyclables, and RDF. The facility supports both village panchayats and municipal councils, contributing significantly to a cleaner and more sustainable environment in South Goa. The project is celebrated as one of the best practices in waste management in Goa, making a visible difference in the area. The paragraph concludes with a congratulatory message to the team for their role in driving Goa's green campaign and waste-to-energy initiatives.
