Aerosols 

 

 

 

 

 

One? Two? Nonsense! Go round and count. You probably have more than ten. According  to market researchers, you should have more. Worldwide, people are buying more and more aerosols. But apparently most German customers still think aerosols are dangerous to the environment. Maybe others think that aerosols cannot be recycled. What is the truth about these fears?

 

 

They provide good, safe storage and convenient use. Farmers spray on pesticides with aerosols, the police use aerosols to spray surfaces for fingerprints, cleaners use them to remove chewing gum from clothes or streets.

 

 

It was invented in the 1920s in Norway, but it did not become widely used until the 1940s. After the Second World War, consumption rose steadily.

In 1988 environmentalists found that a chemical in aerosols was damaging the ozone layer. In 1990, however, scientists developed a new kind of aerosol which does not contain the damaging chemical.

 

 

Most people still think aerosols damage the ozone layer. Some even believe that it is not possible to recycle aerosol cans. And in fact, it is difficult because most cans are still made from aluminium which does not stick to a magnet.

It is therefore very hard to extract aerosol cans from unsorted garbage.

 

 

Renewable Energy

In the next years we could increase the amount of energy we get from renewable sources, such as sunlight, wind, water and the tides. Saving energy and using energy more efficiently could cut our energy need by fifty per cent.

Acting along these lines could dramatically cut the pollution we produce, and help to slow down the global warming.
