Our ziplock bags are certified compostable under AS 4736 for industrial composting facilities.
However, due to the 150-micron thickness of the ziplock closure, the bags do not fully meet AS 5810 home composting requirements.
If disposing of the bags in a home composting environment, the ziplock closure must be detached and removed before placing the remaining bag material into the home compost bin.
