Yes – in a compost environment the pouch will break down in 26 weeks into water, co2 and biomass, just like other organic materials such as paper. This pouch has been independently tested and accredited for eco-toxicity, disintegration, and biodegradation to known standards such as OK Compost Home, Seedling, ABA and Cré. Because the zipper is ‘Industrial’ compost certified only, this means the process may take longer than 26 weeks for this part of the pouch.
