Certification mark for biodegradable plastic during composting



Plastic that undergoes degradation by biological processes during composting to yield CO2, water, inorganic compounds and biomass at a rate consistent with other known compostable materials and leave no visible, distinguishable or toxic residue.

Basis of certification (test Requirements):

The certification mark is awarded within the framework of voluntary testing and certification. It demonstrates that the product has been tested and certificated by the third-party organization TUV SUD. The certification mark is only affixed to the products that undergone inspection by TUV SUD Product Service and comply with the criteria quoted below.

Key STATEMENTS of the certification mark:

  • ≥ 90% Biodegradation rate

    Breakdown of an organic chemical compound by micro-organisms in the presence of oxygen to carbon dioxide, water and mineral salts of any other elements present (mineralization) and new biomass or in the absence of oxygen to carbon dioxide, methane, mineral salts and new biomass. The biodegradation rate shall not less than 90%.

  • ≥ 90% Disintegration rate

    Physical breakdown of a material into very small fragments: The plastic product or material shall disintegrate during composting such that any remaining plastic is not readily distinguishable from the other organic materials in the finished compost. Additionally, the plastic product or material shall not be found in significant quantities during screening prior to final distribution of the compost. The disintegration rate shall not less than 90%.

  • Ecotoxicity tested

    Ecotoxic effects on 2 higher plants shall be determined by comparing compost produced with and without addition of packaging material. The seedling germination rate of the finished compost and the plant biomass in the compost shall be no less than 90 % of that of corresponding blank composts to which no test or reference material was added at the start of testing.

  • Toxic substances tested

    This test refers to the negative effects on the quality of the resulting compost, it is the concentrations of regulated metals and other toxic substances in the plastic product or material shall be less than 50 % of those prescribed for sludges, fertilizers and composts in the country where the final product will be placed on the market or disposed of.

  • Type tested

    The voluntary certification mark with the statement „Type tested“ is issued for products and components. The certification mark demonstrates that the product/component was tested and certified by the independent third-party organisation of TÜV SÜD Product Service for conformity with the essential technical safety requirements. The certification criteria vary depending on the products in question.

  • Production monitored

    Periodic surveillance and/or monitoring of the manufacture of a product constitutes the basic premise for certification that includes the award of a certification mark. Certification always requires product testing and regular factory inspections.

    As a third-party expert organisation, TÜV SÜD Product Service verifies that the manufacturer is able to maintain consistent quality in line with the requirements throughout high-volume production and has established the necessary quality system, including incoming goods inspections, lists of materials and final product testing.

    In addition, calibration of the necessary measuring and monitoring equipment must be ensured. Surveillance and/or monitoring covers the testing of safety-critical components and other materials used. If unauthorised changes are made to the product, the certificate will become invalid and the TÜV SÜD certification mark may no longer be used.
