Legacy waste management system

What is Legacy Waste Management?

Legacy waste management involves the scientific handling, processing, and remediation of old, untreated waste dumped over years in landfills or open dumpsites. This waste poses serious environmental and health threats due to its long-term degradation and potential to release toxins into soil, water, and air.

In India, managing legacy waste has become a top priority under Swachh Bharat and Smart City initiatives. Modern legacy waste solutions, including biomining of legacy waste, help in recovering resources like RDF (Refuse Derived Fuel), recyclables, and inert material reducing landfill load and reclaiming valuable land.

What is Legacy Waste?

Legacy waste refers to old, accumulated waste that hasn’t been treated or disposed of properly. It includes household waste, plastics, construction debris, industrial byproducts, and sometimes hazardous materials often found in dumpsites across cities.

Legacy Waste Processing: How Our Plant Works

At Arcler, our legacy waste recycling plant follows a structured and efficient process designed specifically for Indian dumpsite conditions. Unlike fresh waste processing, legacy waste management in India begins with screening, as the waste is already aged and mixed. Here’s how the process works:

1. Primary Screening (100 mm Trommel / Screen)

The legacy waste is first passed through a screening system (typically 100 mm). This helps in dividing the waste into three major fractions based on size:
< 20 mm → Mostly inert material like soil, sand, and fine particles
20 mm to 80 mm → Organic material & small Combustible fraction (plastics, textiles, organic residue) Need to explain what to do with this fraction → Combustible fraction & bigger inert
The fine inert fraction (<20 mm) is separated early, reducing load on downstream equipment.

Handling of Oversized Fraction (> 80 mm)

The material larger than 80 mm is sent to a ballistic separator or wind shifter. This stage is critical for:
Removing heavy inerts like stones, bricks, and debris
Separating light combustible materials from heavy rejects
Reduce landfill waste with waste-to-energy conversion
After this step, the cleaned combustible fraction is recovered for further processing.

Recovery of Combustible Fraction (20–80 mm + Processed Oversize)

The combustible materials obtained from:
20–80 mm screened fraction
Output from ballistic separation
are combined and prepared for size reduction.
This fraction is rich in plastics, paper, textiles, and other high-calorific materials ideal for fuel production.

Primary Shredding

The recovered combustible waste is fed into a primary shredder. This step:
Reduces size of mixed materials
Ensures uniform feed for further processing
Improves handling efficiency

Fine Shredding for RDF Production

After primary shredding, the material undergoes fine shredding to achieve the desired particle size.
This stage ensures:
Consistent output size
Better calorific value
Compliance with fuel requirements
The final output is Refuse Derived Fuel (RDF), widely used in cement plants and waste-to-energy facilities.
Primary Shredder : First Step of Size reduction to make uniform material
Screening : Separating required size of material fraction
OBMC (Over Bend Magnetic Separator) : To remove metals
Air Density Separator : To separate out Light & Heavy Fractions
Fine Shredder : As Secondary Shredder, it delivers required consistent quality of RDF

Biomining of Legacy Waste and What’s Found in Legacy Dumpsites

Biomining of legacy waste is a sustainable and scientific method used to process old, untreated waste lying in open dumpsites. This technique involves the use of mechanical separation and biological treatment to recover useful materials, reduce environmental hazards, and reclaim valuable land.

In India, biomining has become a key solution under urban waste remediation programs, helping municipalities manage large-scale dump yards in an eco-friendly manner. The goal is to recover resources like Refuse Derived Fuel (RDF), recyclables, and inert material, while minimizing the volume of waste that ends up in landfills.

Common Types of Waste in Legacy Dumpsites:

Legacy waste is usually a complex mix of:
Household waste (organic and plastic materials)
Industrial byproducts
Construction and demolition debris
Inert waste like sand, stone, and clay
Ferrous and non-ferrous metals
Hazardous and electronic waste in some cases

Biomining helps safely process these waste streams by separating valuable fractions from inerts and contaminants. It’s one of the most effective legacy waste solutions used for large-scale dumpsite cleanup in India.

Compliance and Environmental Benefits

At Arcler, our legacy waste management solutions are designed to meet all required environmental and regulatory standards in India. We follow the guidelines laid out by the Central Pollution Control Board (CPCB) and support the initiatives under the Swachh Bharat Mission for effective dump site remediation.

Our processes ensure full compliance with waste management rules while promoting sustainable recovery methods like biomining and RDF generation. We also maintain proper documentation and reporting throughout the waste processing cycle to help our clients meet legal and environmental obligations.

Key Environmental Benefits:

Reduction in Landfill Volume

Biomining helps reduce the size of legacy dumpsites, freeing up valuable land for future use.

Pollution Control

By safely treating old waste, we prevent harmful leachate and gas emissions from contaminating soil, air, and groundwater.

Resource Recovery

Materials like RDF, metals, and recyclables are extracted and reused, promoting a circular economy.

Improved Public Health & Hygiene

Removing decades-old waste from urban areas significantly lowers health risks for nearby communities.

Frequently Asked Questions

What is legacy waste and how is it different from regular waste?
Legacy waste refers to old, untreated waste that has accumulated in open dumpsites over the years. Unlike regular municipal solid waste, legacy waste often includes a mix of household garbage, plastics, construction debris, industrial residues, and sometimes hazardous materials. It remains unprocessed and poses long-term environmental and health risks.
What is biomining of legacy waste and how does it work?
What kind of waste is found in legacy dumpsites?
Legacy dumpsites often contain a mix of household waste, industrial byproducts, plastics, construction and demolition debris, metals, inert materials (like sand and stone), and in some cases, hazardous or electronic waste. These materials need specialized processing for safe disposal or recovery.
