The seedling logo is a symbol that the product’s claims of biodegradability and compostability as per AS4736 has been verified.

The ABA launched Australian Standard 4736-2006, compostable and biodegradable plastics – “Biodegradable plastics suitable for composting and other microbial treatment” which is known as the ‘seedling logo’ certification system throughout Australia and New Zealand. The seedling logo clearly identifies and differentiates packaging materials as biodegradable and compostable. To be certified compostable and carry the seedling logo, suitable biopolymer materials must undergo a stringent test regime outlined by AS4736 and carried out by recognised independent accredited laboratories to the AS4736 standard.

Owing to the comparatively smaller volume of waste involved, the temperature in a garden compost heap is lower and less constant than in an industrial composting environment. This is why composting in the garden is a more difficult, slower-paced process.

TÜV AUSTRIA’s answer to this challenge was to develop OK compost HOME to guarantee complete biodegradability in the light of specific requirements, in your garden compost heap.
