What is polystyrene?

Polystyrene (Styrofoam in the USA) is a strong plastic created from erethylene and benzine that can be injected, extruded or blow molded, making it a very useful and versatile manufacturing material. Most of us recognize styrofoam a form of foam polystyrene packaging. Polystyrene is also used as a building material, with electrical appliances (light switches and plates), and in other household items. 

For more go to how  polystyrene was invented

 How is Polystyrene (styrofoam) made?
Polystyrene (styrofoam) is extracted from oil. Thousands of small units of styrene, called monomers, link together to form large molecules of polystyrene by a process called polymerisation.

Expanded polystyrene starts as small spherical beads with a typical diameter of 0.5-1.5mm. They contain an expanding agent;

When the beads are heated with steam, the agent starts to boil, the polymer softens and the beads expand to about forty times their initial size. After a maturing period to equilibrate temperature and pressure, the pre-foamed beads, which now have a closed cellular foam structure, are placed in a mould and again reheated with steam.

The mould can be designed to meet any requirements of the customer. The pre-foamed beads expand further, completely fill the mould cavity and fuse together. When moulded, nearly all the volume of the EPS foam (in fact 98%) is air. This is what makes EPS so lightweight and buoyant.

Polystyrene – the quick facts

It contains styrene which is according to some is  a toxic carcinogen that does leach into from the container into the contents – your coffee for example – try this site for an in depth discussion of the issue. 

As with all plastics it  lasts an incredibly long time. Consequently plastic cups and clam shells can be seen littering the environment the world over -  litter that doesnt biodegrade.

It causes the death of  animals  who accidentally ingest it.

In the old days in couldnt be recyled now it can but facilities are limited. Though of course that may well change in the future

Polystyrene and the OZONE LAYER

There are other issues with polystyrene the expanding agent that causes the styrene to puff up affects the ozone layer

However, despite EPF’s popularity and unique features, it has recently come under attack because of the gaseous methane derivatives—chlorofluorocarbons (CFCs)—used to foam it. CFCs are inert, and harmless to humans and the environment upon their release. However, long after their first use, scientists realized that CFCs contribute to the depletion of the ozone layer as they decompose. The ozone layer is a layer of the atmosphere that protects the earth against harmful ultraviolet rays from the sun. In 1988 representatives from 31 nations signed the Montreal Protocol, a treaty with which they resolved to halve CFC production by 1998. This agreement brought EPF to the world’s consciousness as a threat to the ozone layer. While foam packaging is responsible for less than three percent of the CFCs being released into the atmosphere, EPF reduction has been targeted as a way to lower CFC levels, and new technology that explores ways to produce EPF without CFCs has flourished.

However environmentalists disagree see rebuttal

As with all plastic the arguments are split between the producers and the environmentalists and can be very basically summarised as follows: superlative product with a myriad of wonderful applications, recyclable and above all completely inert and safe – consumerism gone mad and leacher of carcinogenic chemicals.

But whichever your school of thought all agree that its looks nasty, is polluting the environment and lasts a very long time.

So lets not use it to make throw away items.

Disposing of polystyrene

As with all plastic polystyrene does not biodegrade. Instead it hangs around for years creating everlasting litter and problomatic pollution.

the boffs are working on the problem and here are their solutions

Recycling

Polystyrene is difficult to recycle. Difficult but not impossible …

For those of you who insist on using plastic cups there is  the  save a cup recycling system

For the other stuff there is a  process for recycling  polystyrene that uses  the styromelt system.

The Rest

Polystyrene that ends up as litter has to be picked up – by the council – you pay the cost or by decent folk who care about the environmnet.

I’m not sure I can “have a nice day” if there is this much Styrofoam in the garbage. Read more about why Polystyrene is hazardous to your health and to the environment ask rosie
