4-Stage Waste Separation & Recovery

From toxic dumpsites to clean, high-value resources. Every ton is stabilized, sorted, and recovered with zero waste sent back to landfills.

Stage 01 · Bio-Stabilization

Decontamination & Odor Elimination

What It Achieves: Safely neutralizes raw, rotting dumpsite waste before sorting—stopping foul odors, preventing dump fires, and drying the material so machines can process it without clogging.

Engineering Specs Excavated waste is laid into aerated windrows and sprayed with bio-culture inoculants. Slashes moisture from >55% down to <25%, destroys toxic volatile organic compounds (VOCs), and cools hot leachate.
Stage 02 · Mechanical Sorting

Multi-Deck Trommel Screening

What It Achieves: High-speed rotating sieves automatically sort mixed waste by particle size, separating large debris from valuable burnable fuel and rich organic bio-soil.

Engineering Specs Sequential rotary trommels with calibrated aperture decks (100mm, 50mm, 16mm, and 4mm) tumble and divide material into oversized rejects, intermediate RDF combustibles, and fine mineral fractions.
Stage 03 · Air & Magnet Sorting

Air Classification & Metal Extraction

What It Achieves: Uses high-velocity air streams to separate light plastics for green fuel while extracting 99.5% of recyclable scrap metal, leaving only clean stone rubble.

Engineering Specs Aerodynamic air knife separators float lightweight plastics (RDF) away from heavy masonry and glass. Overband cross-belt neodymium magnets capture 99.5% of ferrous metals.
Stage 04 · Resource Recovery

Zero-Landfill Product Dispatch

What It Achieves: Turns 100% of excavated waste into revenue-generating commodities and reusable industrial materials—sending zero waste back to landfills and freeing up prime urban land.

Engineering Specs Sub-4mm fine fraction is enriched with mycorrhizal nutrients for agriculture; high-calorific RDF is baled for cement kilns; polymers are baled for upcycling; and inert gravel is dispatched for road base.
