You probably have a difficult time imagining a world without plastics and everyday life would certainly be very different without them.
Pre-reading: The picture below is of the WEEE man. He is 7 meters tall and weighs 3.3 tonnes. He is constructed from the average amount of electrical and electronic products that one person throws away in their lifetime.
Can you identify some of the products? How many of these products contain plastic, do you think? Can you guess what WEEE is an acronym for?
In Everyday Life
The first man-made plastic was made in the middle of the 19th century and called Parkesine, but it is only in the last fifty years that the use of plastics has exploded. Their extensive use today has many positive aspects, but also far-reaching negative ones.
Plastic has many advantages.
- It is light-weight and therefore has low transportation costs.
- A car containing a large amount of plastic will weigh less and use less fuel.
- The volume of plastic waste is less than other materials that it can replace.
- The plastic industry is big and employs many people.
- It is relatively inexpensive to produce plastic and it can be adapted to the specific needs of the customer by using different additives.
- It is durable and has excellent insulation properties.
Pollution by plastic waste is a growing problem and is the biggest disadvantage of using plastic. Plastic is non-degradable and can therefore exist for a long time in a landfill. Plastic objects discarded in the environment cause problems for wildlife and pollute our countryside and seas. Although plastic can be recycled, Waste Online UK estimates that only 7% of the total plastic waste in the UK is currently being recycled. The different types of plastic have to be separated before recycling, which increases the costs.
In addition, the additives, which are added to plastics to give them the properties that the customer desires, can be harmful to the environment.
Modbury is a small town in the south-west of England which became famous world-wide in May 2007. All the traders in the town stopped supplying plastic bags and sold reusable biodegradable bags instead. In this way, they could contribute to reducing the amount of plastic waste. Modbury bans plastic bags
The BBC Natural History Unit made a film, Message in the Waves, which deals with Hawai'i and environmental problems. It shows some of the effects of pollution by plastic waste. This film so affected a local woman in Glastonbury, in Somerset, that she organized a group of people to do something about plastic bag pollution. Cotton shopping bags have now been produced for sale , Glastonbury goes plastic bag free (BBC News, 16 February 2008). Here in Norway, a Kragerø bank with the cooperation of a local artist, who was also influenced by the film, has produced reusable bags of sail cloth decorated by the artist. (From the newspaper, Varden, 31 October 2008)
