In typical parlance, the term biodegradable means something different from compostable. Biodegradable simply means that the object can be broken down by bacteria or other organisms, whereas ‘compostable’ in the plastics industry is defined as being able to break down in an aerobic environment maintained under specific controlled temperature and humidity conditions. Compostable means capable of biodegradation in a compost pile, making the material visually indistinguishable and decomposing into carbon dioxide, water, inorganic compounds and biomass at a rate consistent with that of known compostable materials.

The inclusion of “inorganic material” excludes the end product from being considered compost or humus, which is purely organic material. In fact, the xxx criterion required for a plastic to be called compostable under the ASTM definition is that it must disappear at the same rate as other things that are already known to be compostable under the traditional definition.

Plastic bags can be made “oxo-biodegradable” by being made from a common plastic polymer (i.e. polyethylene) or polypropylene and mixed with an additive that causes the polymer (polyethylene) to degrade and then biodegrade due to oxidation.

Most bags made from plastic are made from corn-based materials, such as polylactic acid blends. Today, biodegradable plastic bags are as strong and reliable as conventional (mainly polyethylene) bags. Many bags are also made from paper, organic materials or polycaprolactone.

“The public thinks biodegradable is something magical,” despite the widespread use of the term, according to Ramani Narayan, a chemical engineer at Michigan State University in East Lansing and a scientific advisor to the Biodegradable Plastics Institute. “It is by far the most commonly used and most often misused and misapplied word in our lexicon. In the Great Pacific Garbage Patch, biodegradable plastics break down into smaller pieces that can more easily enter the food chain by being consumed.”
