World leader in determining biodegradability and compostability

Hands with compost

OWS now also accredited for home composting tests and biobased testing

Since the 1990s, OWS has been recognised as a lab by DIN CERTCO for performing industrial composting tests. Since then, OWS has already helped hundreds of customers in carrying out the necessary tests and obtaining the eponymous logo.

In June 2013, DIN CERTCO extended the certificate and OWS was also recognised to perform home composting tests and biobased tests.
