A compostable product is made from renewable raw materials and is capable of composting in to the natural elements in a composting environment, leaving no toxicity in the soil within 12 weeks.
For packaging products to be accepted at a commercial composting site they will need to meet internationally recognised compostability standards either EN13432 or ATSM D6400.
The composting process consists of mixing the product with food waste and using heat, water and oxygen to break the material down. After 12 weeks at least 90% of the material will pass through a 2mm sieve.
