INTRODUCTION
Interest in biobased and biodegradable polymers is increasing, due to concerns about managing carbon emissions in a sustainable manner, and the environmental requirements for the safe and effective disposal of polymers (like plastics) after use when they enter the waste stream (1). Starch and cellulose polymers derived from biofeedstocks are also increasingly being used, either directly or as blends with other biobased and biodegradable polymer materials (2), (3). Blends of polycaprolactone (PCL) and starch offer cost-performance benefits with increased biodegradability: Starch can enhance the biodegradability and reduce the cost, whereas PCL offers ...
