Starch-based bioplastic that is said to be biodegradable and sustainable is potentially as toxic as petroleum-based plastic, and can cause similar health problems, new peer-reviewed research finds.
Bioplastics have been heralded as the future of plastic because it breaks down quicker than petroleum-based plastic, and is often made from plant-based material such as corn starch, rice starch or sugar.
The material is often used in fast fashion clothing, wet wipes, straws, cutlery and a range of other products. The new research found damage to organs, changes to the metabolism, gut microbe imbalances that can lead to cardiovascular disease, and changes to glucose levels, among other health issues.
The authors say their study is the first to confirm “adverse effects of long-term exposure” in mice.
Unfortunately, most bioplastics are more like 300 years, which yes, is significantly better than 300 thousand years, and with industrial compost heaters you can push those 300 years down. But I’ve also had to come to terms that my failed 3D prints will likely outlive me (although I do collect the waste to hopefully recycle someday). I don’t print that much compared to most in the hobby, but it is something I consider before I print things.
That said, I’m not going to let perfect be the enemy of good, and the biodegradability of bioplastics is still exponentially better than petroleum plastic.
