Biodegradable resources

Biodegradable materials organically break down into natural elements relatively quickly. These materials depend on microorganisms, UV light exposure and hydrolysis to naturally dissolve the original material into water, carbon dioxide, methane, biomass or other inorganic compounds.

Not all biodegradable materials can degrade in all environments. Depending on design, the materials may biodegrade more effectively in treatment plants while others may do better in soils. It is important to consider how these materials will be handled at end-of-life and whether they will end up in an environment that promotes biodegradability.

Note: Biodegradable materials are not the same as compostable, bio-based or renewable resources.
