According to the Central Pollution Control Board (CPCB), bio-mining is the scientific process of excavating, treating, segregating, and profitably utilizing aged municipal solid waste lying in dumpsites, also known as legacy waste. Swachh Bharat Mission (SBM) 2.0 has given cities with a population of less than one million a clear mandate to remediate existing legacy waste dumpsites by March 31, 2023. For cities with more than a million people, the deadline is a year later.

Bio-mining of legacy waste is going to gain significant traction across the country in the next few years fuelled by the financial assistance from SBM 2.0. Use of reclaimed land will also be a critical issue for city authorities to ensure best utility after necessary scientific investigations. 

Even before SBM 2.0, cities such as Indore, Bhopal, Ambikapur, Kumbakonam, and Tirupati had completed bio-mining projects. These cities' reclaimed land has been put to good use in a variety of ways. In Indore, for example, the land was used to build waste-processing facilities such as a bio-CNG plant, a material recovery facility, and a construction and demolition waste-processing plant. The remaining land has become a city forest.Management of legacy waste has created an ecosystem of technology-based solutions for deriving land as a resource from legacy waste dumpsites. But it came with its unique operational and technical challenges. 

We offer legacy waste bio mining services, which include excavating old dumpsite waste, processing legacy waste with a mechanized trammel and screen system, disposing of segregated components - inert, soil, RDF, rejects, and so on - in accordance with solid waste management guidelines, and clearing and handing over cleared land to municipal authorities. We currently manage two bio mining sites for legacy waste in Uttar Pradesh (Lalitpur and Etawa).
