Our bin liners are made from a compostable resin named Mater-Bi produced by Novamont, an Italian research company dedicated to environmental alternatives to polyethylene-based plastics. Mater-Bi is an innovative family of bioplastics that uses substances obtained from plants, such as but not limited to, non-genetically modified corn starch, and biodegradable/compostable polymers obtained both from renewable raw materials and fossil raw materials. Novamont’s policy is to acquire and use exclusively natural, non-GM, raw materials (such as starch).
No, the liners are certified compostable and contain a variety of compostable polymers so they can safely be eaten by worms and microorganisms, leaving no toxic residues or microplastics behind.
Yes, in an active compost environment, our liners will break down within a matter of weeks and at the same rate as your food scraps. Success of home composting depends on how rich your compost is and the conditions unique to your compost bin and your location, including outside temperatures, moisture levels and the number of active microorganisms. The bags break down at normal compost temperatures and don’t need to be heated to high temperatures to break down. Yes, these bin liners can be placed in a worm farm sporadically however, they are much better suited for the compost bin. If placing in a worm farm we recommend chopping the bags into little bit so it is easier for the worms to break down.
It will break down anywhere oxygen and microorganisms are present and microorganisms are everywhere. If a bin liner becomes litter today, it only has a matter of weeks to reach the marine environment, whereas plastic bags remain in the environment for hundreds of years. Our number one goal is offering an alternative to plastic bags. If we can divert just one gram of plastic away from landfill then we’re happy. Even if they don’t make it into a compost bin, they’re still better for the environment as a whole because they don’t break down into microplastics and they have a lower carbon footprint than plastic which is made from oil – a non-renewable resource.
Yes, when you try them you’ll see the strength of a BioBag is comparable to a normal plastic bag and the technology is improving all the time.
