Capable of being broken down by microorganisms under particular environmental conditions.
The word does not say where, how fast or how completely a material breaks down. In the United States, the FTC’s Green Guides apply their degradable guidance to biodegradable claims: an unqualified claim needs “competent and reliable scientific evidence that the entire item will completely break down and return to nature (i.e., decompose into elements found in nature) within a reasonably short period of time after customary disposal.” Unqualified claims for items customarily sent to landfills, incinerators and recycling facilities are deceptive, because those places “do not present conditions in which complete decomposition will occur within one year.”
In the EU, Directive (EU) 2024/825 lists “biodegradable” and “biobased” among examples of generic environmental claims, which it prohibits unless the trader can demonstrate recognised excellent environmental performance or the claim is specified on the same medium; its rules have applied in the Member States since 27 September 2026. The European Commission notes that bio-based plastics are “not necessarily biodegradable or compostable.”

Biodegradability comes up in packaging and materials work. Packaging development roles replace virgin plastics with recycled or bio-based materials, analyze recyclability and environmental impact with life-cycle assessment tools, and prepare for the EU Packaging and Packaging Waste Regulation. See current packaging development roles.
