23 Mar 2022 --- Researchers at NC State University, US, have developed a new biomaterial that could help solve the worsening problem of plastic pollution. Lokendra Pal and Lucian Lucia, professors in the Department of Forest Biomaterials, have discovered how to convert leftover sawdust powder and agro-residues into styrofoam-like packaging material. “Our technology represents a significant breakthrough in enhancing [environmental and economic] sustainability while meeting the cost and performance targets needed to make a paradigm shift from plastics-based single-use items, mainly packaging,” the researchers tell PackagingInsights.“We know this material is not only recyclable and environmentally compatible, but also biodegradable in saltwater. It will simply disappear over time and consequently provide nutrients to aquatic life.”The researchers say the wood-based material could someday replace the plastics found in many single-use items. With support from the Chancellor’s Innovation Fund, Pal and Lucia are currently conducting pilot trials, in advance of testing and commercialization by potential industry partners. The researchers say they are currently focused on manufacturing packaging and foodservice products.Pal and Lucia say current pilot trials include high throughput standard molding processes and the evaluation of commercial viability. “Further, we are looking into developing a continuous process utilizing 3-D printing. Currently, we have two major focus areas – peanut packaging and foodservice items. For the foodservice sector, we are focusing on plates, bowls, cups, utensils, and various other items.”
