090011: Fabrication and Characterization of Biodegradable PLA-Zeolite Composites

Modified Atmosphere Packaging (MAP) enhances quality, extends the shelf life of perishable foods, and prevents loss revenues due to food spoilage. MAP is required because the balance and interaction of certain gases, such as carbon dioxide (CO2) and oxygen, with packaged foods contributes to either poor or high food quality. Advances in packag...

070021: Poly (1,4-benzodioxepin-3-alkyl-2,5-dione)s: Degradable Polymers with High Glass Transition Temperatures

Polylactic acid (PLA) is growing rapidly in popularity as an alternative to petroleum-derived plastics. It is biodegradable, thermoplastic, and derived from renewable resources. However, polylactides must be crystalline tor them to be dimensionally stable above 50° C, which is a characteristic that limits its use for some applications. Manipula...

050110: Biodegradable Plastics with High Glass Transition Temperatures Replace PET and Polystyrene

Beginning around 1995, the inventor took an interest in finding ways to make polymers from natural resources since it was apparent that petroleum-based polymers would eventually increase markedly in cost as the world reserves of petroleum diminished. An associate suggested they research making polymers from hydroxyl acids. This led to the idea ...

050009: High Impact-High Stiffness Bacterial Bioplastic

This technology is a new approach for producing biodegradable plastic that overcomes some prior limitation inherent in the use of Polyhydroxybutyrate (PHB). PHB is a desirable material because of its high crytallinity and water resistance. Crytallinity is when chains pack closely together in a regular way, allowing stronger intermolecular force...

040132: A Reactive Extrusion Process for Formation of Biodegradable, Bioabsorbable Co-Polymers of 1,4-Dioxan-2-one and a Cyclic Ester

Current methods for producing these polymers typically result in low conversion of monomer to polymer product. Removal of the monomer is a time and cost intensive procedure. Description This invention describes an approach to synthesize copolymers of 1,4-dioxan-2-one and a cyclic ester using continuous extrusion and an organometallic polymeriza...

040109: Novel "Green" Materials from Soy Meal and Natural Rubber Blends

Petroleum-based plastics are derived from a non-sustainable source, for which alternatives are presently sought. These plastics are also environmentally burdensome because they are not biodegradable. This and other drawbacks associated with petroleum-based plastics have led to increased research efforts toward the development of biodegradable a...

020043: Environmentally Friendly Polylactide-Based Biocomposite Materials for Flooring

The growing environmental awareness, increasing societal concern and new environmental rules and regulations have triggered a paradigm shift in designing and engineering of eco-friendly green materials for flooring applications. Polylactic acid (PLA) polymers or polylactides are useful biodegradable polymers because of their origin from renewa...

000020: Process for the Preparation of Polymers of Dimeric Cyclic Esters

Polylactic acid (PLA) is growing rapidly in popularity as an alternative to petroleum-derived plastics. It is biodegradable, thermoplastic, and derived from renewable resources. Presently, the preparation of crystalline materials requires enantiopure L-lactide, where lactic acid is produced by microbial fermentation, and the cyclic lactide mono...
