Legacy Waste Management (Bio-mining)

Landfills Shouldn't
Fill Lands Forever!

BioMining is the process of segregating the already-accumulated urban legacy solid wastes, helping in cleaning up legacy dump sites. This helps scientifically reclaim these lands for better usage. This is extremely crucial today, as the dump yards that were conceptualized originally to be outside the city are right at the epicentre of real-estate development these days. SWMS is one of the leading players in this space and has been working on about 9 sites spread across the state, including Pallikaranai, Sattangadu, Villupuram, Rasipuram and Thoothukudi.
SWMS has partnered with the Corporations of Tiruppur and Tirunelveli, and many other Municipalities to carry out the Primary and Secondary collection and transportation.
Beauty Shines Where Cleanliness Begins.

Our Process

Step 01

The legacy wastes are sliced into parallel vertical heaps for measurement.

Step 02

They are turned multiple times in a week to stabilize the wastes thereby stopping the production of leachate or methane.

Step 03

The dried and decomposed waste is subject to segregation via trommel, screening into different factions, and they are segregated into fine sand, stones, soiled plastics, rags, footwear, bottles, tires, heavy metals, decomposed paper, and more.

Step 04

Wastes like plastics, rags, and tires that cannot be repurposed are sent to cement factories as Refused Derived Fuel (RDF), laying roads, or pelletization

Step 05

The fine sand is taken by farmers and the coarse sand finds its application in land-filling and construction
