Materials

What are you throwing away?

The right machine depends on the material. Moisture content and flame-retardant treatment matter most.

  • EPS styrofoam

    Ordinary expanded polystyrene from packaging and cushioning. Every densifier handles it.

  • Wet styrofoam

    Fish boxes and fishing buoys saturated with water — processed without drying, melting or preheating.

  • Flame-retardant EPS

    Flame-retardant insulation board, handled by cold-type compactors that emit no odour or gas.

  • Marine buoys & nets

    Buoys recovered from the sea, fouling and all, densified on a dedicated compaction line.

  • PSP · EPP · EPE

    Instant-noodle cups, cushioning foam and other expanded resins.

  • Polyurethane foam

    Polyurethane foam from sandwich panels and insulation.

Where it goes next

What happens after densification

Ingots produced on site are pelletised into recycled feedstock, or used for solid fuel, fuel oil, lightweight concrete and adhesives. A large share is exported.
