Foam boxes used in fruit and vegetable transport and the trays meat products are often packaged in, are made from a plastic called expanded polystyrene (EPS). EPS is manufactured using oil and petrochemicals. This type of EPS is used as it is an insulator against any temperature change, is durable, and protects because of its shock absorption. EPS is also very lightweight, consisting of 98% air (EPS recycling) and therefore as a form of packaging, its weight does not particularly affect the weight of the product. Today, EPS has many other uses such as building insulation and as a soil conditioner improving drainage and aeration.

However, resource consumption is minimal. Expanded polystyrene packaging uses less than 0.1% of the world’s oil, while over 86% is used for transport and within homes.

EPS Boxes | EPS Compactor | Hasswell TechnologyPolystyrene recyclers are able to remanufacture more than 99.9% of the EPS they receive, with the remainder being sent to landfill. However, in Australia, EPS recyclers are only located in State capitals and therefore it is necessary to be mindful of the waste it creates. While being chlorofluorocarbon (CFC) free and non-toxic, EPS is non-biodegradable (meaning it doesn’t break down in nature). Almost all foam consumer waste is disposed of in landfills, and although itis light in weight, it takes up a lot of space due to its bulkiness.

Recycling EPS has a number of stages: first it is segregated, compacted and collected. It then undergoes granulation into smaller pieces, blended with other granules and is melted. While melting, colour can be added and remoulding can take place. EPS trays and boxes can be remoulded to produce loosefill packaging, recycled into items such as video and CD cases, coat hangers, and plant pots and reused as an aggregate for lightweight concrete.

EPS Densifiers with Silo System

Expanded Polystyrene (EPS) Recycling is not difficult at all. There are several EPS compactor suppliers from Europe, USA and China that can help you reduce your polystyrene waste disposal costs drastically. Available compactors with capacities from 15 cubic feet of un-densified polystyrene per hour up to 600 cubic feet per hour.

Polystyrene, Expanded Polystyrene (EPS) or Styrofoam is 98% air and 2% air. How much are you paying to transport it to landfill? If you are spending more than USD50 a week disposing of EPS waste then it will pay you to have a EPS compactor. If you are loading up a van and taking your EPS to landfill think what else you could do with your time! It quickly fills skips and bins taking up large amounts of space but weighing almost nothing: pushing up waste disposal costs. Just think: you are paying your waste contractor to transport 98% air to landfill.

It is a huge problem for organisations in the food industry (hotels, restaurants, fast food), or buyers of supplies packaged in polystyrene (fisheries, hospitals, electronics industry, cruise companies, white goods suppliers). And yet polystyrene has a high price as a recycled product: anywhere between USD200 and USD400 a tonne when compacted. Many recyclers, traders, and Polywood product producers will buy your compacted polystyrene.

The smallest machine which compacts 15 cubic feet of Styrofoam per hour, up to 50:1 compaction, 95% reduction in volume. Density 25 lb per cubic foot once compacted. Huge reduction in waste disposal costs. Easily loaded by hand or via conveyor for larger installations. Variable block sizes depending on machine.

EPS Silo System For Highest Throughput

Styrofoam Densifier Silo

 

For people need silo systems to enable higher loading capacities. The oversized pre-crush hopper can be bucket-fed or conveyor fed. The pre-crush unit is connected to a simple air-blown system to fill a silo 300 cubic feet in capacity.

 

 

The silo can feed one or two compactors to increase the throughput even further.

This is an ideal solution for a recycler collecting Styrofoam from multiple sources or a high volume Styrofoam waste producer who wants minimal operator time.

EPS packaging has a positive environmental record:

■ Ozone-depleting CFCs or HCFCs have never been used in the manufacture of EPS

■ The manufacture of EPS packaging is a low-pollution process

■ Computer-aided design ensures that the minimum amount of material is used to make an appropriate EPS pack

■ The excellent protection and insulation offered by EPS helps to prevent wastage and spoilage

■ EPS is 100 per cent recyclable and 100s of tonnes of EPS are recycled each month in the UK

■ EPS is inert and innocuous and provides stability in landfill because it does not biodegrade and leach chemicals into the water system or gases into the air that could contribute to global warming

■ The use of EPS for insulation in the construction industry helps to reduce the energy used to heat and cool buildings

EPS packaging offers outstanding performance that is cost-effective and totally reliable:

■ A moulded EPS pack is not damaged by moisture, damp or heat and continues to protect products whatever the external conditions

■ EPS is 98 per cent air making it one of the lightest packaging materials available anywhere

■ Outstanding shock absorption and compression resistance can be designed into an EPS package

■ EPS is an excellent insulator providing a thermal conductivity of 0.038 W/mK at 15g/l density and in-pack coolants can increase insulation performance

■ Fruits and vegetables retain their vitamin C content longer if they are packed in EPS

Every day of our lives EPS contributes to our safety:

■ EPS is used to make cycle helmets and child car seats because of its ability to absorb shock

■ EPS is used to package shellfish, fresh fish and other vulnerable foodstuffs ensuring that they arrive in our homes
fresh and safe to eat

■ Vaccines and other temperature sensitive medicines are packed in tested EPS packs; guaranting that the vaccines are both effective and safe to use

■ EPS is used in lifebelts and lifejackets to provide buoyancy

■ In combustion the amount of carbon monoxide and particulates given off by EPS is a small fraction compared to that
of wood or cardboard

■ EPS can be used by children in art and science classes — it is light, has no sharp edges and can be safely cut, scraped and painted

Polystyrene Properties

Polystyrene is the common name for the alkene polymer styrene, a petroleum by-product with the repeating formula H2C=CHC6H5. C6H5 is a phenyl group, which is comprised of a benzene ring with one hydrogen atom removed. Although first produced in the 1930s, styrene’s first significant role was in the production of synthetic rubber during the Second World War. It was not until after the war that the commercial use of polystyrene became prominent.

There are several forms of polystyrene. The first is made without any additives and is considered general-purpose polystyrene. In this form, polystyrene is a brittle, clear material that can be easily colored. This material is used for injection molding to make such things as CD cases, boxes, and ballpoint pens.

Polystyrene can also be blended with rubber to produce another useful material. While this material has reduced tensile strength and modulus, it displays an increased toughness that sustains high impact. This type of blended polystyrene is used for such applications as television and radio cases.

The forms of polystyrene most identifiable to the public are the extruded and expanded foams. The extruded foams are used in the making of food service containers, meat trays, plates, and cups. The expanded foams are used as packing material for the protection of fragile goods during shipping. Pentane and carbon dioxide are used in the manufacturing of these types of polystyrene foams.

Polystyrene is best known for its efficiency, cost-effectiveness, and sanitation. The material is lightweight, cushioning, and easily conforms to any shape. Therefore, it is ideal for protecting packaged goods during shipping. Polystyrene’s efficiency begins with the initial low cost of styrene. In most cases, only five percent of the final product is comprised of polystyrene while air makes up the other ninety five percent. Thus, a cost savings is demonstrated for industries using polystyrene products.

The exceptional insulating capabilities of polystyrene help prevent the spoilage and waste of food by maintaining the temperature of cold and hot food. Polystyrene packaging meets all of the U.S. FDA standards for food industry use. Service-ware made from polystyrene has been proven to be more sanitary than reusable service ware. Additionally, polystyrene service-ware products reduce water usage. To promote food safety, health officials advocate the use of singleuse food service ware. And, in the food industry, cost efficient polystyrene utensils and containers have replaced reusable, as well as paper, food utensils.

No Comments
Posted 15 Feb 2012 — by editor
Category Application

Recycled EPS packaging can be used either to make more packaging, or to make other products. In

order to make more packaging it is granulated and blended with virgin EPS foam beads to make new

EPS mouldings. It can also be blended with virgin crystal polystyrene and re-gassed to make EPS

loose fill packaging.

Other products that can be made from recycled EPS include:

• Video and CD cases

• Coat hangers

• Plant pots

• Hardwood replacement – used for garden furniture, picture frames and so on.
