What makes bioplastics different from compostable plastics?

Bioplastics differ from compostable plastics primarily in their feedstock origins and degradation capabilities. Bioplastics can be non-biodegradable or partially biodegradable, originating from both bio-based and fossil sources. They are defined as being derived from biological materials, regardless of biodegradability^[4]. Compostable plastics, however, are specifically designed to break down under industrial composting conditions, adhering to strict standards that ensure they decompose within a defined time frame, typically in such facilities rather than home compost bins^[6].

Common misconceptions include the belief that all bioplastics are compostable or that they will biodegrade in any environment; this is not the case, as many require specific conditions to decompose efficiently^[4].
