Biodegradation depends on environment
Temperature, moisture, oxygen and microorganisms all matter.
Compostable is a more specific claim
Standards can specify breakdown and residue requirements under defined composting conditions.
Time scale matters
Almost any organic material can eventually change, but useful claims need realistic conditions and times.
Disposal systems matter
A material is only useful as 'compostable' if the local system can actually process it.
