Technical Abstract: Agricultural and environmental application of biopolymers and bioplastic blends is currently an active area of research at USDA. Polymeric materials with predictable properties and controlled performance are being developed by blending starch with other low-cost renewable polymers. Renewable polymers derived from crop residues and industrially processed fruits and vegetable wastes have been utilized to produce wood adhesive, mulch films, packaging materials, biodegradable cast films, and melt-extruded composites. In particular, an overview will be presented to discuss the development of: (1) starch-PVOH melt-extruded films and (2) a starch-PVOH crosslinked wood adhesive for use in interior wood construction. Data will be presented to show the changes assessed in the structure and properties of polymers in a complex matrix and their environmental fate both in their native state and after various chemical, biological, or physical modifications.
