Donald R. Allen received his Ph.D in Physics from Brigham Young University and has worked in product research and development, and engineering management for over 35 years. He is the Technology Director at BiologiQ, Inc., a developer and manufacturer of ESR resins and resin blends.


BiologiQ’s EcoStarch Resin (ESR) is a new type of thermoplastic starch (TPS) resin completely derived from renewable sources. This new ESR resin confers the benefits of thermoplastic starch resins, yet overcomes the challenges that have typically prevented widespread acceptance of TPS resins in the marketplace. The characteristics of ESR that make it unique will be presented. These characteristics include the ability to easily blend ESR with other polymers on existing process equipment, so that significant renewable content can be added to films and injection molded parts. The presentation will show that the addition of ESR can improve film mechanical properties, allowing for additional downgauging beyond traditional levels. The inclusion of ESR in LLDPE films increases the degradation rate of LLDPE films alone, as shown by test studies. The low cost of BiologiQ’s EcoStarch Resin in combination with its renewability, degradability and recyclability, and its ability to be blended easily into polymers provides a strategic advantage to plastics manufacturers worldwide.
