Kochi Corporation’s Brahmapuram biomining costs set to rise
Kochi Corporation will need to biomine an extra 126,000 tonnes of legacy waste, raising costs. The municipal body had previously agreed to pay ₹1,672 per tonne for 196,000 tonnes, costing ₹37 crore. The process involves treating hazardous waste with microorganisms to recover valuable metals. This will significantly increase the overall cost.
