Compostability tests for "OK HOME compost"

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.

TÜV AUSTRIA certifications for compostability

OK HOME compost, OK compost INDUSTRIAL & seedling

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.) 

DIN CERTCO certification for compostability

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.).


Domestic and industrial compostability: two different standards

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.

What tests are used to determine if a product is compostable?

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.

What tests are used to determine if a product is compostable?

01 Identification and chemical characterisation of product components

The constituents and physical characteristics of the product must be determined. 

Chimical tests are made

02 Biodegradation of the product

Determination of the product's capacity to be consumed by an appropriate microbial flora, via the conversion of organic carbon into carbon dioxide.

03 Disintegration of the product

Determination of the physical fragmentation of the product during composting.

04 Ecotoxicity test

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.

Compostable products: what are they exactly?

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.
