Biodegradable

When a product is biodegradable, it can, via bacteria or other living organism, be broken down back into natural elements that disappear into nature, and do not damage the soil. Biodegradable matter is generally materials from plants, animals and other substances originating from living organisms, but it can also be artificial materials that are similar enough to organic matter to be put to use by microorganisms, like biodegradable plastic.

It is important that the material is put in the right environment, or it will not biodegrade.
