Plastic Bottle Compactor - Plastic Recycling

Plastic (PET Bottle) Recycling

PET bottles "polyethylene terephthalate" is the preferred packaging for soft drinks, fizzy drinks, juice and water. This results in large waste problems. For breweries, large volumes of discharged products need to be destroyed regularly in order to eliminate the risks of the bottles being resold again. For waste collectors handling and transport is difficult and expensive, as there is a large discrepancy between weight and volume.

Compact the PET Bottles

Our plastic bottle compactor is a great solution to both problems. When plastic bottles have been through the screw compactor their volume have been reduced 8:1. This results in an easier and cheaper transportation, as well as guarantees that the bottles cannot be resold. Plastic recycling becomes easier and cheaper with the plastic bottle compactor, since in most cases the compacted bottles can be sold for recycling.

RUNI screw compactor compacts and separates continuously the bottles while the liquid is pressed out into a tank or the sewage without making the surroundings dirty. To avoid bridging an agitator can be installed in the hopper. The machines are equipped with sensors for automatic start and stop and can be fed manually, via conveyor belt or tilt container. The compacted bottles are pushed directly into a container.

  • How do you compact plastic bottles?
    Full or empty plastic bottles, cans or tetra pak can be fed into the compactor and are then squeezed until there is no more liquid or air in the bottle.
  • How much can you compact a PET bottle?
    After compacting PET bottles, they achieve a density of approx. 250 kg/m3, which is pretty heavy, and now the PET bottles can be transported and recycled.
