As India's cities continue to grow, the challenge of managing legacy waste—waste that has accumulated over years in open dumps—has become a major concern. These landfills not only occupy vast urban land but also release toxic leachate, methane gas, and harmful pathogens, posing serious risks to public health and the environment.
Enter biomining—a scientific and environmentally sustainable approach that is rapidly gaining momentum across the country. At DCC Group, we are at the forefront of this transformation, helping municipalities and industries adopt advanced technologies for bioremediation of Municipal Solid Waste (MSW) and land recovery.
What Is the Bio Mining Process?
The bio mining process involves the excavation, segregation, and treatment of old waste using a combination of mechanical and biological methods. Unlike traditional landfill management, biomining does not relocate waste to another site—instead, it treats it on location to reduce, reuse, and repurpose various waste components.
The key steps include:
Excavation – Legacy waste is mechanically removed from dumpsites using earthmovers.
Screening – Waste is passed through machines like trommel screens to separate inert material, recyclables, and organic fractions.
Bioremediation – Organic waste is treated biologically using natural microbes to stabilize it, a process known as bioremediation of contaminated MSW.
Resource Recovery – Recyclables are sent for processing, organic matter is composted, and the site is cleared for urban development or green restoration.
Types of Bio Mining Techniques
Biomining can be categorized into various types based on the waste composition and site conditions:
Mechanical Biomining – Involves heavy-duty equipment for excavation and segregation of legacy waste.
Biological Biomining (Bioremediation) – Uses microbes to break down and stabilize biodegradable waste components.
Chemical Biomining (Less Common in MSW) – Applies chemical agents to alter or stabilize harmful substances; more common in mineral recovery.
Hybrid Methods – Combine mechanical and biological techniques for faster and more effective results.
In the context of Municipal Solid Waste, biological and mechanical methods are the most widely used.
Bioremediation of MSW: A Closer Look
The bioremediation of MSW involves enhancing natural microbial activity to decompose and stabilize organic waste. In legacy landfills, organic matter often remains only partially degraded due to anaerobic conditions. Through bioremediation, DCC Group introduces aerobic microbial cultures and maintains proper moisture and aeration, speeding up decomposition and reducing odor, pathogens, and methane emissions.
This approach is particularly effective in bioremediation of contaminated MSW, where untreated waste contains hazardous substances mixed with biodegradable materials. Our controlled bioremediation systems ensure minimal environmental impact while enhancing resource recovery.
Environmental Benefits of Biomining
The long-term environmental benefits of biomining legacy waste are substantial:
1. Land Reclamation
Biomining makes it possible to reclaim land that was previously unusable. These lands can be repurposed into parks, commercial zones, or green infrastructure.
2. Reduced Groundwater Pollution
By removing and stabilizing decomposing waste, biomining reduces leachate that seeps into and contaminates groundwater supplies.
3. Lower Greenhouse Gas Emissions
The biological treatment of waste in aerobic conditions prevents the production of methane—a major greenhouse gas typically emitted by decomposing organic waste in landfills.
4. Improved Air Quality
Stabilized waste reduces foul odors and airborne disease vectors, improving the overall health of nearby communities.
5. Promotion of Circular Economy
Recyclables like plastics, metals, and RDF are recovered and re-enter the economy, reducing the demand for virgin materials.
