The term “biodegradable“ is often used without clearly stating its meaning. It is important to always mention the environmental conditions where the biodegradation happens and how it takes place. Biological degradation depends on natural microorganisms. That is why any statement on the biodegradability can only be given for the respective environmental surrounding, which can be e.g. an industrial composting facility, a home-compost heap or agricultural soil. General statements on the environmental degradability cannot be regarded as reliable. The proof of the complete biological degradability is verified by independent certificates based on approved standards.
For this proof, different countries assign specific test certificates which are based on different standards and ratings:
1. EU: DIN EN 13432
2. USA: ASTM 6400
3. Japan: Green PLA
4. Australia: AS 4736
In different countries, there are special certification methods which independent institutes use to test biopolymers according to their biological degradability, chemical safety and eco-toxicity. Only when a material meets the clearly defined test criteria in standardized test conditions may it be marked e.g. as compostable or biodegradable in the soil.
