Truly biodegradable plastics can be distinguished from so-called ‘oxo-fragmentable’ plastics through the use of labels and certification that adhere to acknowledged industry standards for biodegradation. The European standard for industrial compostable packaging EN13432, for example, is such a clear and specific option, and corresponding certification and labels such as the ‘Seedling’ logo (according to EN 13432) are available to substantiate the claims of biodegradability and compostability.
