Today on Switched On we talk to Dr. Julia Attwood, Head of Advanced Materials for BNEF about bioplastics. Bioplastics comprise just about 1% of the plastics market right now, but its share is growing. Concern about plastic waste in the environment, climate change, and product sustainability has driven interest in bioplastics, though additional capacity has been slow-going.  Julia walks us through the basics and what could push bioplastics to be a more significant part of our daily lives.  Switched On is hosted this week by Mark Taylor and Dana Perkins.See omnystudio.com/listener for privacy information.
