Our knock tube bags fit snugly into standard knock tube systems, while effectively capturing and containing used coffee grounds. Made from Ecopond – a synthetic biodegradable bioplastic combined with plant starch, these certified compostable knock box bags are designed for the circular economy. 

• Our knock tube bags are made from a synthetic biodegradable bioplastic combined with plant-starch – Ecopond.
• These compostable knock box tube liners are certified home compostable to Australian Standards (AS5810) and commercially compostable to Australian Standards (AS4736). That means these compostable bin bags are accepted wherever municipal organic waste collection services exist. If the trash bags end up in the environment, they will biodegrade more rapidly than conventional plastic bags.
• Bioplastics have a 6-month shelf life from purchase and must be stored out of direct sun and below 35°C.
