Giving Cars a Second Life
Mention the word “recycling” and few of us think of cars, But in a world of limited space and resources, recycling everything — even cars — is very important.
Once a car reaches the end of its life, it is taken apart and any parts that can be reused are sold off. The remaining metal is melted down and sold while all the useless materials are just thrown away.
Usually, seventy-five percent of the car can be recycled．But new environmental rules in Europe say that at least eighty percent of old car parts must be recycled by 2006 and ninety-five percent by 2015.
To achieve this, someone has to find a way to recycle plastics, which are usually just thrown away. Fortunately. British scientists have come up with a solution. Through a new recycling process, they break down the plastics into gas, oil and a small amount of carbon (碳) and fibre. This is a big step forward for the car companies, who want to use more plastics to improve a car's efficiency (功率). Companies like BMW are also hoping to use more plastics that are easier to recycle.
