Often made of plant-based matter, compostable plastic is a material capable of breaking down into carbon dioxide, water and biomass at a rate comparable to cellulose. Compostable plastics decompose completely in a composting environment and do not leave any toxic material behind.
The words biodegradable and compostable are often used interchangeably but there are some differences between the two. Both will decompose in a composting environment, however biodegradable products may leave a toxic residue behind. Almost all compostable material is biodegradable, but not all biodegradable material is compostable. Read more here!
Yes. All certified compostable materials will break down when placed in a composting environment in a home or commercial facility.
If you have a home composting facility, you can dispose of the bag in there. If not, you can drop it at one of 150 industrial composting and organics recycling facilities in Australia that accept compostable plastics. Some councils provide composting facilities through their kerbside waste collections – either through green organic and garden waste bin or through dedicated organic recycling service.

Please don’t throw your bag in the rubbish bin. Compostable plastic will not break down in landfill. They require air and moisture to properly decompose, so it’s up to you to ensure your compostable bag ends up in a composting environment.
No, you shouldn’t throw away compostable bags with general recycling. This creates an additional step for the recycling plant to sort out bioplastics from recyclable plastics and it may never end up in a composting facility.
The speed at which your bag decomposes depends on its material makeup and the composting facility it is deposited into. As a general rule of thumb, all Because We Care Australia products will completely compost in 90 to 180 days.
Because We Care Australia products meet the Australian standards for home and industrial composting, which means you can dispose of our bags in either place safely. The real difference is the time it takes to break down. An industrial facility will break down the material faster because there is more movement; the piles are consistently turned over and they reach higher temperatures.
All Because We Care Australia bags are made from renewable plant-based materials. Our film bags, including Doggy Bags, T-shirt Bags and Bin Liners are made from corn starch compostable materials. Our reusable non-woven bags, such as our wine and tote bags, are crafted from tapioca starch.
