Plastics are going “green,” but they will need some help to get there. Biodegradable polymers derived from renewable resources are attracting lots of interest and publicity, but that enthusiasm is counterbalanced by persistent questions of availability, cost, performance, and processability. All these issues are inter-related: Increasing demand will lead to more capacity, which will presumably lead to lower prices. But the foundation is market demand, which ultimately depends on whether biopolymers will have the performance properties and processability to compete with existing non-renewable plastics.
