Therefore, this study uses life cycle assessment (LCA) to compare the environmental impacts of chemical recycling of mixed plastic waste (MPW) via pyrolysis with the established waste management alternatives: m
In recycling, new raw materials are obtained via a mechanical (typically leading to regranulate) or chemical (typically leading to monomer building blocks) pathway. If polymer waste cannot be recycled, energy recovery is the preferred option. Landfill, the least-preferred option, should be avoided...
21,22,23,24 Before these treatments, chemical, mechanical, enzymatic or combined pretreatments are used to improve cellulose fibrillation, obtaining individual cellulosic fibers and decreasing energy requirements of mechanical treatments14,25,26,27,28,29,30,31. Among them, TEMPO-mediated oxidation is ...

The substitution of virgin biodegradable plastics by their recyclates leads to higher savings in the primary energy demand and reduces global warming impact. This review covers the current state of the mechanical, chemical, and bio-recycling of post-industrial and post-consumer waste of biodegradable...
However, FR-containing plastic waste is often landfilled or recycled for energy rather than new products [5,18,19]. Moreover, the recycled plastic waste is typically upcycled by adding FR additives as a route to Design from Recycling [5,20]. In general, two main alternatives are adopted ...
A planatizing equipment has solid abrasive particles suspended in a liquid suspension. The solid abrasive particles have on their outer surfaces tiny, hard but brittle working edges and points. The li
