Bio-mining begins at Koothattukulam waste dump

Kochi: Kerala State Waste Management Project (KSWMP) launched bio-mining operations at the waste disposal site near the market in Koothattukulam municipality as part of efforts to scientifically clear accumulated legacy waste. Officials said around 4,344.76 cubic metres of waste stored at the site will be processed in the coming days.According to KSWMP officials, the bio-mining process will separate the waste into three categories — refuse-derived fuel (RDF), inert waste and bio-earth residue. The project is being implemented with support from the World Bank and Asian Infrastructure Investment Bank (AIIB). RDF is produced by processing non-recyclable municipal and industrial waste materials such as plastics, paper and textiles, and is commonly used as fuel in cement factories. Inert waste refers to non-hazardous solid waste that does not undergo major physical, chemical or biological changes, while bio-earth is the nutrient-rich soil residue obtained after bio-mining. "RDF will be handed over to cement factories, while the inert and bio-earth waste will be tested to ensure there is no contamination as per Pollution Control Board guidelines," a KSWMP official said. Officials added that the environmental and social impacts of the project are being monitored closely and that public consultations are being carried out to ensure smooth implementation. The municipality expects the entire waste removal process to be completed within 15 days.
