A biofriendly new material made from barley starch blended with fiber from sugarbeet waste—a strong material that turns into compost should it end up in nature—has been created at the University of Copenhagen. In the long term, the researchers hope that their invention can help put the brakes on plastic pollution while reducing the climate footprint of plastic production.
Toxicity might also be a concern if you compost it by throwing it into nature. This is my big gripe with all these alternatives: Are they less harmful than (micro)plastic?
