Bio Mining

India’s cities are struggling to manage their waste as these dumpsites have already exceeded their capacity and cannot take in any more waste. They have also not managed to find land for installing waste-processing facilities. These dumpsites have emerged as pollution hubs in the middle of human settlements, as cities have grown over the decades. It has, therefore, become a necessity for the city authorities to reclaim the existing dumpsites in an environmentally sound and economically viable manner. Bio-mining is the scientific process of excavation, treatment, segregation and gainful utilisation of aged municipal solid waste lying in dumpsites typically referred to as legacy waste.”
It is a process of treating garbage or waste with bio-organisms or natural elements like air and
Sunlight. Over time, the biodegradable component of the waste gets decomposed through the
natural process, and the remaining part i.e. non-biodegradable material is then dealt separately.

It comprises 4 steps:
  • Excavation of legacy waste,
  • Stabilising the waste using bioremediation.
  • Segregation of excavated waste and then sustainable management and its safe disposal.
  • Themethods of bio-mining include Bioleaching, Bio-oxidation, Dump leaching, and Agitated leaching.
