Biomining and bioremediation to be used for waste disposal by GHMC

By the utilization of bio-mining and bioremediation techniques at the Jawaharnagar legacy dumpsite, the Greater Hyderabad Municipal Corporation (GHMC) aims to ensure that solid waste is disposed of in an environmentally friendly and sustainable manner.

In the case of legacy dump sites, biomining is most often aided by bioremediation, a unique process that involves microbial degradation of organic waste by adding organisms that facilitate composting. In order to treat legacy waste and reclaim old dump sites, the Central Pollution Control Board (CPCB) recommends ‘bioremediation.’

In an effort to accomplish this undertaking, GHMC has invited a request for proposal (RFP) bid from reputed firms for the disposal of legacy waste from the Jawaharnagar dumpsite.

Through bio-mining and bioremediation, old dump yard material can be converted into reusable resources. In order to grow microorganisms that treat pollutants, environmental conditions will be altered.

Bio-mining and bioremediation of the already capped legacy dumpsite will be the main activity, followed by the removal of various layers of the capping for land reclamation, disposal of recovered materials with appropriate disposal certificates, and disposal of residual solid wastes in engineered landfills.

Another key activity that will be taken up at Jawahar Nagar will be the construction of a leachate treatment plant for managing the leachate generated by existing gas vents and stabilizing the soil of the reclaimed land.

It is expected that the project will be completed within 36 months, including a three-month period for site preparation and mobilizing workers and machinery.

Besides capping the dump yard, the State government had also put in place a 20MW waste-to-energy plant. Additionally, Leachate treatment funds were also approved. The Ministry of Environment and Forest approved the construction of another 28 MW of waste to the energy plant at Jawahar Nagar in December 2021.
