So-called “bioplastics” are marketed as an environmentally friendly alternative to conventional, petroleum-based plastics. They can be made from renewable feedstock, might be bio-degradable or even both. The question is however if these biomaterials are safer than conventional plastics with regard to the chemicals they contain. A new study published today in the journal Environment International addresses this question. Scientists have analyzed everyday products made of bio-based and/or biodegradable materials now report that the chemicals these alternatives contain are similarly toxic like those in conventional plastics.
