Abstract:Liquid package board (LPB) packages typically have the smallest global warming potential compared to other package solutions, but recycling of the integrated plastic and aluminum fractions of the packages is still limited. In the fiber recycling process the plastic and aluminum fractions with some residual fibers are concentrated to the repulping reject (Polyal). This study investigates composition and properties of repulping rejects from recycling of separately collected LPB packages. The rejects were modifie… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
