The promise of environmentally friendly bioplastics that degrade naturally and can then be recycled and reused for productive purposes is largely unfulfilled. Most makers of bioplastics are not following through on what needs to done to ensure bioplastics don’t end up adding to the growing amount of plastics waste that is harming ecosystems in oceans and rivers and across landscapes. Fulton Schools Assistant Professor Taylor Weiss, who is developing algae-based plastics, says bioplastics need to processed at facilities specifically designed to do proper recycling so they don’t become just more greenhouse gas emitting garbage.
