- Styrene is an
aromatic monomer, and polystyrene is an aromatic polymer.
- Polystyrene is
the most recycled form of disposable food service packaging.
- Polystyrene is
being collected in school and corporate cafeterias, restaurants,
grocery stores and/or at curbside in 40 states and sent to
reprocessors around the country.
recycling is particularly successful in institutional settings.
Polystyrene / EPS is PS Foam that use Pentane gas (C5H12) as the
- There are
different types of plastics, ones which can be remoulded termed as
thermoplastics, such as polystyrene (PS), poly-propylene(PP,
polyamides (nylons), polycarbonate(PC), poly-ethylene(PE) and
- Polystyrene is a
polymer made from the monomer styrene, a liquid hydrocarbon that is
commercially manufactured from petroleum. At room temperature,
polystyrene is normally a solid thermoplastic, but can be melted at
higher temperature for molding or extrusion, then resolidified.
Polystyrene (EPS) is a lightweight, rigid cellular plastic that is
made from the polymerisation of styrene monomer.
- Polystyrene Paper
(PSP) is a PS Foam which produced by extruding process as another
- EPS and PSP Foam
are made of Polystyrene, which is thermoplastic, so that it will
become again a polystyrene plastic when recycled.
- PS pallet from
recycled foam will be produced in various kinds of plastic products
e.g. video and tape cassette and ruler. The other way to reuse EPS
Foam is to mix the regrind beads with the new expanded bead for
re-production in molding process.
EPS waste can be reground and mixed with concrete to produce new
building products such as Rastra and prefabricated concrete blocks.
polystyrene is being used in egg cartons and sandwich containers.
- It is desirable
to recycle polystyrene foam to reduce the amount of plastic in
- In terms of
global warming, EPS plays a positive role in reducing carbon dioxide
- EPS has become
over the year a commodity of premium importance in building and
packaging markets. EPS contains 98 % of air, which makes it
difficult to recycle due to the high transport costs.
- It is
conservatively estimated that well over 300,000 tons of waste EPS
are produced on an annual basis in the UK. In the USA according to
the EPA over 377,579 tons of Polystyrene are produced in California
- Reducing the
amount of landfill space EPS takes by up to 95% would be reason
enough to thermally compact and densify this material.
- It is estimated
that approximately 15.2 million pounds (58 percent) of the 26.2
million pounds of EPS packaging recycled during some year were
remanufactured into new EPS packaging.
