By definition, most chemicals are biodegradable because they’re capable of being broken down by the action of living things, such as microorganisms. Current international guidelines stipulates that the entire package should be completely broken down and returned to nature within a “reasonably short period of time”
Foodware ONLY claims to be biodegradable when it has NO:
- evidence of being certified to have met international standards;
- information on how long the decomposition takes and the by-product that is left behind. This is very much dependent on the composition of the material and the environment in which the decomposition occurs. Biodegradability is not only based on the feedstock of the product but on the chemical signature, that is the way the plastics are put together.
