If you don't have your own compost setup at home, consider checking out starting your own. Australian residents can even save up to 80% through their local council. Check it outhere.
If that's not an option for you you can start one through your workplace by teaming up withPlanetArk or at home with your local neighbourhood withShareWaste. Otherwise, find a local compost facility withPlanetArk.
Otherwise check with your local council and see if they allow for compostable materials in their green bins or worst case it can go into landfill.
