Corn-Based Plastics Reinforced by Lignin and Cellulose Nanofibrils (RFT 633)
Invention Summary
The increasing environmental impacts associated with petroleum-based polymers have intensified interest in renewable materials. Corn-based materials like start, zein, and polylactic acid (PLA) are notable alternatives. This technology focuses on a corn-based thermoplastic composition that incorporates lignin and cellulose nanofibrils to enhance it structural properties. By integrating these reinforcing agents, the composition achieves significantly improved mechanical properties and water resistance. The blend primarily includes corn-derived starch and zein, supplemented by variable quantities of lignin and cellulose nanofibrils, along with a plasticizer to aid processing.
Benefits
- Enhanced Mechanical Properties-the addition of lignin and cellulose nanofibrils strengthens the material, making it comparable to conventional plastics in terms of durability.
- Improved Water Resistance-these compositions are less susceptible to moisture, addressing a common weakness of many biodegradable plastics.
- Versatility in Manufacturing-suitable for various forming techniques including injection molding, extrusion molding, and 3D printing, allowing for diverse product applications.
- Environmental Advantage-offers a sustainable alternative to petroleum-based plastics, aligning with global trends towards reducing plastic waste and carbon footprints.
Applications
- Packaging Solutions-particularly suitable for food packaging where biodegradability is a desired trait
- Agricultural Applications-useful in making biodegradable mulch films, plant pots, and seed trays
- Consumer Goods-can be used in disposable cutlery, plates, and other household items that benefit from compostability
