India’s growing urbanization has led to an ever-increasing volume of municipal solid waste (MSW). With waste piling up in landfills, the challenges surrounding its management have become critical. Fortunately, biomining offers a sustainable and environmentally friendly solution to remediate these massive dumpsites, while also recovering valuable resources and generating energy. At Maan Enviro Technologies, we design and manufacture advanced solid waste management equipment, including state-of-the-art biomining plants that are changing the way waste is managed.
What is Biomining?
Biomining is the process of excavating and processing old, decomposed waste from landfill sites, often referred to as legacy waste. This waste typically consists of both organic and inorganic materials that have accumulated over the years.
The Biomining Process:
- Excavation of Legacy Waste: The process begins by excavating old waste from dumpsites.
- Microbial Treatment: Microorganisms are introduced to the waste to accelerate the digestion of organic material, breaking it down into more manageable components.
- Segregation of Waste: Once the organics are digested, the remaining inorganics, such as plastics, rubber, metals, and partly digested waste, are separated using equipment like trommel screens and air density separators.
- RDF Production: The inorganics are processed to create Refuse-Derived Fuel (RDF), which can be used as an alternative energy source, reducing reliance on fossil fuels.
- Final Output: This process not only clears the dumpsite but also transforms waste into RDF, making it a noble solution for waste management.
The Environmental Benefits of Biomining
Biomining offers numerous environmental advantages, making it an essential practice for modern waste management in India.
- Reduction of Landfill Space: By processing and reducing legacy waste, biomining helps clear up valuable land that can be repurposed for community use.
- Energy Recovery: Through the production of RDF, waste that would otherwise sit idle in a landfill is converted into a resource for energy generation.
Lower Greenhouse Gas - Emissions: Biomining reduces methane emissions, which are typically released by decomposing waste in landfills.
- Resource Recovery: Valuable materials like metals and plastics can be recovered and recycled, contributing to a circular economy.
- Groundwater and Soil Protection: Dumpsites are known to leach toxic substances into the soil and groundwater. Biomining mitigates this by properly treating and removing harmful waste.
Mangalore Biomining Success Story
One of the most notable biomining projects in India is the ongoing remediation of the Mangalore dump site, where 9 lakh tonnes of legacy waste is being processed. The facility is installed and being operated by Hydromech Technology in a joint venture with NACOF India Ltd.
The results? From the 9 lakh tonnes of waste, the project is producing 1.5 lakh tonnes of RDF, a clean energy source that is significantly reducing the landfill burden while contributing to sustainable energy production. The Mangalore project is a shining example of how biomining, combined with cutting-edge waste management equipment, can transform waste into a resource.
Why Biomining is the Future of Waste Management
With India’s rapid urbanization, more and more cities are looking to biomining as a sustainable solution for managing their legacy waste. The need for land reclamation, coupled with the growing demand for renewable energy, makes biomining an ideal solution for the future.
At Maan Enviro Technologies, we are proud to be at the forefront of this waste management revolution, providing tailored biomining solutions that benefit both businesses and the environment. Whether it’s designing trommel screens, air density separators, or complete RDF processing plants, we are committed to helping India build a cleaner and greener future.
