Using biodegradable and compostable plastic products such as biowaste bags, fresh food packaging, or disposable tableware and cutlery increases the end-of-life options. In addition to recovering energy and mechanical recycling, industrial composting (organic recovery / organic recycling) becomes an available end-of-life option. Compostability is a clear benefit when plastic items are mixed with biowaste. Under these conditions, mechanical recycling is not feasible, neither for plastics nor biowaste. The use of compostable plastics makes the mixed waste suitable for organic recycling (industrial composting and anaerobic digestion), enabling the shift from recovery to recycling (a treatment option which ranks higher on the European waste hierarchy). This way, biowaste is diverted from other recycling streams or from landfill and facilitating separate collection – resulting in the creation of more valuable compost. http://docs.european-bioplastics.org/publications/bp/EUBP_BP_En_13432.pdf Do (industrially) compostable plastics decrease the quality of the compost? Compostable plastics that are tested and certified according to the European standard for industrial composting EN 13432 are required to disintegrate after 12 weeks and completely biodegrade after six months. That means that 90 percent or more of the plastic material will have been converted to CO2 phone fax European Bioplastics e.V. Very short composting cycles may not be sufficient to allow for a full disintegration of some types of biowaste as well as for some compostable plastic packaging. However, leftover scraps (usually ligno-cellulosics) in composting plants are sifted out and added to the next fresh compost batch for another composting cycle where they fully metabolise to water, carbon dioxide, and biomass. e-mail web Marienstr. 19/20, 10117 Berlin +49.30.28 48 23 50 +49.30.28 48 23 59 email@example.com www.european-bioplastics.org http://docs.european-bioplastics.org/publications/bp/EUBP_BP_En_13432.pdf What is the difference between oxo-fragmentable and biodegradable plastics? So-called ‘oxo-fragmentable’ products are made from conventional plastics and supplemented with specific additives in order to mimic biodegradation. In truth, however, these additives only facilitate a fragmentation of the materials, which do not fully degrade but break down into very small fragments that remain in the environment. Biodegradability is an inherent characteristic of a material or polymer. In contrast to oxo-fragmentation, biodegradation results from the action of naturally occurring microorganisms. The process produces water, carbon dioxide, and biomass as end products. Oxo-fragmentable materials do not biodegrade under industrial composting conditions as defined in accepted standard specifications such as EN 13432, ISO 18606, or ASTM D6400. . The remaining share is biomass, which no longer contains any plastic. EN 13432 also includes test on eco-toxicity and heavy metal contents to ensure that no harmful substances are left behind. http://docs.european-bioplastics.org/publications/bp/EUBP_BP_En_13432.pdf http://www.european-bioplastics.org/bioplastics/standards/oxo-degradables/ http://docs.european-bioplastics.org/publications/fs/EUBP_FS_Standards.pdf http://docs.european-bioplastics.org/publications/bp/EUBP_BP_Additivemediated_plastics.pdf How can one distinguish oxo-fragmentable from biodegradable plastics? 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.
