Globally there are a number of Certification regimes in place to cover the recognised compostability of products, the majority of which are location / regionally specific.  The first of these to be recognised was the European EN13432 – 2000 certification regime for compostable products.  This was followed by the North American ASTM D6400 – 2004 and the Australasian AS 4736 – 2006.  Each of these standards are similar in coverage but have region specific requiremental differences and management programs.  The most widely recognised management programs for EN13432 – 2000 are provided by either TUV Vincotte (Austria) {Ok Compost} or Din Certco (Germany) {Seedling Logo}.  The ASTM D6400 – 2004 (BPI) program is provided by Biodegradable Products Institute in the USA and the AS4736 program is provided by the Australasian Bioplastics Association (ABA) {Australasian Seedling Logo}.

Because We Care is the holder of a wide variety of certifications issued by these organisations and provides access to them for clients that it manufactures products for.

Other certification regimes in place that Because We Care participates in include {OK Compost Home & 4 Star Bio-based Product} (TUV Vincotte) {Europe} BNQ 0017-988 {Canada} and AS5810 – 2010 Home Compost {Australasia}

Both AS 4736 and AS 5810 have an additional testing requirement over the other regimes which is commonly known as the worm test.  This testing regime requires that the compost resulting from the primary tests conducted to meet EN13432 and ASTM D6400 be put through a series of further tests to determine the quality of the resultant compost.   To achieve this outcome several sets of worms are placed into the compost on a “go / no go” basis where they must show an increased number and an increased weight from when the test commenced and in comparison to a set in commercial compost or the test fails.  Similarly a set of rye grasses undergo a similar test where they must also show an enhanced growth profile with a similar comparative outcome required.
