In nature, different materials biodegrade at different rates. If you throw your apple core into the bushes along with a steel toy car, your apple core will have disappeared in a few months and your toy car will be rusty but still recognisable. It may take many years before the toy car disappears entirely. To be able to work effectively, most microorganisms that assist the biodegradation need light, water and oxygen. Temperature is also an important factor in determining the rate of biodegradation. This is because microorganisms tend to reproduce faster in warmer conditions. Many products that are biodegradable in soil – such as tree trimmings, food wastes and paper – will not biodegrade when we place them in landfills, because the artificial landfill environment lacks the light, water and bacterial activity required for the decay process to begin. The Garbage Project is a study of waste conducted by a group at the University of Arizona, USA. The project has unearthed from landfill hot dogs, corn cobs and grapes that were 25 years old and still recognisable, as well as newspapers dating back to 1952 that were still easily readable!

The most common type of plastic shopping bag – the kind you use to get at supermarkets – is made of polyethylene, a person-made polymer that microorganisms don't recognise as food. So, if there is no CO 2 production for plastic in respirometry tests, where does the 500-year estimate come from? Although polyethylene bags don't biodegrade, they do photodegrade. When exposed to ultraviolet radiation from sunlight, polyethylene's polymer chains become brittle and start to crack. This suggests that plastic bags will eventually fragment into microscopic granules. Scientists do know that many plastic break down into microplastics, as of yet, however, scientists aren't sure how many centuries it takes for plastics to completely break down and 'disappear'. That's why some people give a 500 year estimate, while others prefer a more conservative 1000 year lifespan. According to some plastics experts, all these figures are just another way of saying ‘a really, really long time’.
