What Is a Landfill Mining Plant?
A landfill mining plant is an integrated system designed for landfill mining and legacy waste processing, which excavates, screens, separates, and recovers aged buried waste from old landfill sites. It processes mixed materials such as decomposed municipal solid waste, plastics, metals, soil-like fines, textiles, wood, and inert debris through crushing, screening, magnetic separation, and density sorting to enable efficient old waste recovery.
As a key solution for landfill reclamation, landfill mining helps reclaim valuable landfill space while converting buried waste into reusable resources. Recovered metals can be recycled, combustible fractions can be processed into RDF fuel, and screened soil-like materials can be reused for backfilling or site restoration. This process not only creates economic value from historical waste deposits but also reduces long-term environmental risks such as leachate contamination, methane emissions, and land occupation.

Why Landfill Mining Matters?
Landfill mining is becoming an essential strategy for modern waste management and landfill reclamation. It enables operators to recover valuable materials from buried waste, extend landfill service life, reduce environmental liabilities, and transform old disposal sites into reusable land and resource assets.
Recover Valuable Resources: Recover recyclable metals, RDF fuel, soil-like materials, and recycled aggregates from aged waste to create new economic value.
Reclaim Landfill Space: Excavate and process legacy waste to release valuable landfill capacity for future waste management needs.
Reduce Environmental Risks: Minimize leachate contamination, methane emissions, and long-term soil and groundwater pollution risks.
Support Circular Economy: Convert historical waste deposits into reusable resources, reducing dependence on virgin raw materials.
Lower Remediation Cost: Reduce long-term landfill closure, monitoring, and environmental remediation expenses through active resource recovery.
What Materials Can Be Processed?
Landfill Mining Plants are engineered to process diverse legacy waste fractions commonly found in old landfill sites, including decomposed municipal waste, soil-like fines, plastics, metals, organic residues, and inert construction debris for efficient resource recovery and landfill reclamation.
Sorting Process
The flow includes waste excavation, feeding and pre-screening, trommel screening for size classification, magnetic separation for metal recovery, air density separation for light materials, manual or optical sorting for fine purification, RDF recovery, soil fraction refinement, and final material utilization or disposal.
With a processing capacity of 30–500 TPH and recovery rates of 70–90%, the system converts mixed legacy waste into reusable metals, RDF fuel, recycled aggregates, and soil-like materials, reducing landfill volume and enabling resource reclamation.
System Equipment
A landfill mining plant is composed of a heavy-duty feeding system, multi-stage screening units, and advanced separation equipment designed to handle highly mixed, wet, and decomposed waste. The production line focuses on stable material handling, efficient size classification, and high-precision resource recovery. With properly configured systems, recovery rates can reach 70–90%, significantly reducing landfill volume while maximizing metals, RDF fuel, and reusable soil fractions.
Provides stable and continuous feeding of uneven landfill waste, handling large and heavy materials up to 800–1200 mm.

Material & Final Products
Landfill mining does not simply remove waste—it transforms long-term buried materials into usable resource streams through multi-stage separation and refinement. The output structure is highly dependent on waste age, composition, and processing configuration, but generally includes recyclable metals, energy-grade combustible fractions, soil-like materials, plastics, and inert aggregates. These recovered materials reduce landfill volume and create measurable economic return through secondary utilization.
Challenges in Landfill Mining & Our Solutions
- Aged landfill waste often contains high moisture and sticky fines, leading to screen clogging and reduced throughput.
- → Anti-blocking trommel structure, reinforced screening media, and optimized material flow reduce sticking and improve continuous operation.
- Waste includes soil, plastics, metals, organics, and inert materials mixed in irregular proportions.
- → Multi-stage separation combining screening, ballistic separation, magnetic and density sorting enables stable fraction classification.
- Excavation and handling of decomposed waste generates odor emissions and airborne dust.
- → Fully enclosed conveying with negative pressure extraction and centralized filtration ensures compliant emission control.
- Random material distribution and contamination reduce separation accuracy and resource recovery rates.
- → Fine grading, staged sorting, and optimized process flow increase recoverable fractions and overall efficiency.
- Landfill sites often have uneven terrain, limited working space, and phased operation requirements.
- → Modular, skid-mounted system design allows flexible layout, fast installation, and easy relocation or expansion.
