everyday
home-compostable
breakdown can occur in an ordinary household compost system
not when This claim is false for products that need industrial heat or controlled moisture.
professional
compostable
material meets conditions for becoming usable compost
not when Compostable is a narrower claim and often requires a certified facility.
professional
industrially compostable
certified breakdown requires a commercial composting process
not when The phrase should not suggest the item will decompose in soil or landfill.
formal
bioerodible
technical writing concerns gradual breakdown in a biological environment
not when Bioerodible is specialized and may describe surface loss rather than complete decomposition.
formal
decomposable
the broad ability to break into simpler matter is enough
not when Decomposable does not say biological action is responsible or that residues are safe.

biodegradable packaging
Biodegradable packaging still needs clear disposal instructions.
biodegradable material
The biodegradable material broke down under the certified test conditions.
fully biodegradable
The manufacturer documented that the film is fully biodegradable in industrial compost.

Biodegradable does not by itself state the required conditions, time, certification, or safety of residues. Those facts must be supplied separately.
