Paper Fiber/Low-Density Polyethylene Composites From Recycled Paper Mill Waste: Preliminary Results, 1994 Recycling Symposium Proceedings
Brent English, James P. Schneider
A method is being developed to utilize large quantities of paper fiber/low- density polyethylene (LDPE) waste generated at pulp mills that recycle poly-coated paper. More commonly called “waste poly rejects”, this material comes from the recycling of paper coated with LDPE film, such as aseptic packaging (juice boxes) and other food containers. Research at the USDA Forest Service, Forest Products Laboratory in cooperation with private industry and the University of Wisconsin-Stout is addressing how this valuable resource can be reclaimed and recycled into value-added products using conventional plastic recycling technology, which involves dewatering, densification, and pelletization of the waste poly rejects, and conversion of the material into products. Full mechanical and rheological property tests are being conducted on the resultant composites at various stages of the process.
