Biodegradable Materials - are capable of being broken down especially into innocuous products by the actions of living things. Examples are:
- Leaves
- paper
- wood
- plant matter e.g grass
- Toilet paper
- cardboard
- paper towels, napkins
- newspaper
- junk mail
- food scraps
- coffee grounds
- ashes
- yard waste
Bacteria are surprisingly adaptive organisms and can biodegrade a very wide range of materials which would not ordinarily be thought of as biodegradable. As bacteria can "eat" them they can be put into the biodegradable class as well.
It is fairly common knowledge that some bacteria adapt to eat heavy hydrocarbons from oil spills and are used to clean up this type of environmental problem. Similar bacteria can even eat asphalt in a high concentration of sodium chloride. Deep sea bacteria near black smokers (volcanic vents) consume toxic sulfides as a source of energy. Some bacteria even eat iron and sulphur compounds. Examples are Acidithiobacillus ferrooxidans (also known as. Thiobacillus ferrooxidans) and Acidithiobacillus thiooxidans (also known as Thiobacillus thiooxidans or Thiobacillus concretivorus) excreting iron and sulfuric acid.
