WESSLING offers laboratory compostability tests to determine whether or not products are suitable for composting.
Our laboratory is certified by two different certification bodies : OK HOME compost, OK compost INDUSTRIAL and Seedling by TUV AUSTRIAa and HOME COMPOSTABLE by DIN CERTCO.
WESSLING is one of the first French laboratories to be certified by TÜV AUSTRIA, a certification body for compostability and biodegradability tests.
TÜV AUSTRIA issues the OK HOME Compost and OK INDUSTRIAL certifications according to the tests carried out (compostability in a domestic or industrial environment. Further explanations are made below.)
Our laboratory is the first and only French laboratory certified by DIN CERTCO for home compostability tests.
WESSLING, when carrying out compostability tests in its French laboratory, can have the tested product certified for you by TÜV AUSTRIA (OK HOME Compost, OK INDUSTRIAL compost, and seedling) and DIN CERTCO (HOME COMPOSTABLE).
Why be certified by third parties?
Certification bodies such as TÜV AUSTRIA or DIN CERTCO have extensive experience and expertise in their field. Being certified is proof of rigorous compliance with the applicable standards and good laboratory practice. It is a guarantee of quality. In addition, access to labels such as OK HOME Compost, OK INDUSTRIAL Compost or Seedling facilitates the marketing of products internationally (credibility, reliability, etc.).
In France, product compostability is currently regulated by two different standards: NF EN 13432 and NF T51-800.
The NF T51-800 standard defines the characteristics that a product must have in order to be considered compostable in a private or domestic context (OK HOME compost for TÜV AUSTRIA and HOME COMPOSTABLE for DIN CERTCO). NF T51-800 is based on NF EN 13432, which regulates characterisation of a compostable product in an industrial environment (OK compost INDUSTRIAL for TÜV AUSTRIA). The two standards differ because the composting conditions are slightly different. In a domestic setting, smaller volumes are composted at lower temperatures. This makes the process more difficult, so that the demands placed on the products to be composted are greater.
WESSLING offers tests on packaging products and other products, of plastic, paper or bio-sourced materials, to determine whether they are compostable in a domestic or industrial context.
WESSLING subjects products to the following successive tests. Packaging that has passed all four tests may be submitted to TUV AUSTRIA or DIN CERTCO to obtain the appropriate label.
The constituents and physical characteristics of the product must be determined.
Determination of the product's capacity to be consumed by an appropriate microbial flora, via the conversion of organic carbon into carbon dioxide.
Determination of the physical fragmentation of the product during composting.
Determination of the quality of the compost resulting from disintegration. Verification that there is no risk of residues of the product tested to human health, animal health and the environment.
Products tested by WESSLING and certified by a third-party certification body (like TUV AUSTRIA) are compostable by private individuals and/or in an industrial environment. In concrete terms, a domestically compostable product can put in any composter. The certified product will degrade in the composter in a few weeks or months, depending on its characteristics.
