Our compostable mailers are made from corn starch derived from waste corn, which is not fit for consumption, PLA (Polylactide, made from waste corn and other plants) and PBAT (Polybutyrate Adipate Terephthalate, a compostable polymer that adds flexibility and strength).
The timeframe to biodegrade will depend on the conditions it is subjected to. In industrial composting facilities they breakdown in less than 3 months. For home composting they break down in 6 to 12 months, so long as the compost is turned and watered properly.
Yes our compostable mailers are worm-food friendly! The home compostable certification in Australia includes a worm toxicity test that must be passed before they can be certified as compliant.
Peel off any adhesive labels and additional packaging. Then put the mailer in your home compost bin. Make sure you add water and turn the compost regularly. Turning the compost weekly is ideal. Your compost needs to be kept moist but not wet, so the amount of water will depend on where you live and what season it is. It's good to check the compost weekly and give it a short spray of water if it's not longer damp.
Because the mailers are designed to breakdown they need to be stored in a cool, dry place with the mailers sealed. If kept in these conditions they should last for 8 to 12 months in storage.
