EPS Compactor ">Polystyrene (also known as EPS Foam or Styrofoam) is a highly popular plastic packaging material which finds wide application in packaging of food items, electronic goods, electrical appliances, furniture etc due to its excellent insulating and protective properties. Polystyrene is also used to make useful products such as disposable cups, trays, cutlery, cartons, cases etc. polystyrene recycling machine |
Despite the attractiveness of polystyrene, municipalities and organisations are facing a growing problem in disposal of polystyrene packaging and products. Being large and bulky, polystyrene take up significant space in rubbish bins which means that bins becomes full more quickly and therefore needs to be emptied more often. Polystyrene is lightweight compared to its volume so it occupies lots of precious landfill space and can be blown around and cause a nuisance in the surrounding areas.
Although some companies have a recycling policy, most of the polystyrene still find its way into landfill sites around the world. As per conservative estimates, hundreds of thousands of tons of waste polystyrene is produced in the Middle East and sent to landfills each year.
While it is estimated that EPS foam (or polystyrene) products accounts for less than 1% of the total weight of landfill materials, the fraction of landfill space it takes up is much higher considering that it is very lightweight. Furthermore, it is essentially non-biodegradable, taking hundreds perhaps thousands of years to decompose. Even when already disposed of in landfills, EPS can easily be carried by the wind and litter the streets or end up polluting water bodies. When EPS foam breaks apart, the small polystyrene components can be eaten by animals which can cause choking or intestinal blockage.
Polystyrene can also be consumed by fishes once it breaks down in the ocean. Marine animals higher up the food chain could eat the fishes that have consumed EPS, thus concentrating the contaminant. It could be a potential health hazard for us humans who are on top of the food chain considering that styrene, the plastic monomer used in manufacturing EPS has been classified by the US National Institutes of Health (NIH) and the International Agency for Research on Cancer (IARC) as a possible human carcinogen. Styrene is derived from either petroleum or natural gas, both of which are non renewable and are rapidly being depleted, creating environmental sustainability problems for EPS.
EPS Recycling Compactor
There seems to be a common misconception that polystyrene is non-recyclable. Being a thermoplastic, it can actually be melted and molded into many different plastic items. At present, the recycling of polystyrene (or EPS foam) basically follows the following process:
Compaction – EPS foam products are fed to a in order to reduce its volume. Some compactor systems have a compaction ratio of up to 50:1, which means that it can reduce the volume by up to 98%.
Shredding – Larger pieces are shredded into flakes. Packaging “peanuts” – small EPS foam pieces used to cushion fragile items – normally skip this step and are fed directly to the pelletizing machine.
Melting/Extrusion – The flakes are forced through pelletizing extruders where they are heated and melted, then allowed to cool in order to solidify. The resulting material can then be used, through reheating and melting, to produce clothes hangers, picture frames, DVD cases and numerous other plastic products.
