Sustainable Chain Extenders for Recycling Polyesters

Executive Summary Polyesters comprise a significant portion of plastics entering landfills. One issue that limits their recycling is natural degradation during melt processing which lowers their molecular weight and melt viscosity. Reactive chain extenders are often used in this case to build back the molecular weight of the polyester during reprocessing....

Repulpable Omniphobic Paper Packaging Solution

Executive SummaryTraditional grease- and water-resistant paper packaging solutions have significant environmental concerns. Water-resistant products using low-density polyethylene (LDPE) liners are not repulpable, increasing municipal waste footprint. Oil-resistance is often achieved using toxic per and polyfluoroalkyl substances, which have been associated...
