Performance of Glass Fiber Composites With Plastic‐Waste Pyrolysis Char as Filler

open access: yesPolymer Composites, EarlyView.
Valorisation of mixed plastic waste into carbonaceous char via pyrolysis, its integration as a microfiller in epoxy/E‐glass (GFRP) laminates, and characterisation to assess composite performance as a function of filler loading. ABSTRACT Plastic pyrolysis offers circular solutions for mixed plastic waste but leaves a carbonaceous char that is often ...

Pretreatment Effects of Conventional and Reactive Extrusion on LLDPE Waste Pyrolysis

open access: yesPolymer Engineering &Science, EarlyView.
Schematic overview of the pyrolysis study using original and pretreated LLDPE waste samples. Pretreatment was performed via twin‐screw extrusion at 450°C: without additives (REX), with peroxide (REX‐RO2), or with polypropylene (REX–PP). All four samples underwent pyrolysis at 450°C–475°C for 15–45 min.

Application of Non‐Isothermal Network Theory With Curved‐Channel Element Characteristics to Predict Melt Conveying in High‐Performance Single‐Screw Extruders

open access: yesJournal of Polymer Science, EarlyView.
This study presents a fast and accurate calculation tool to predict conveying of polymer melts in single‐screw extruders. Integrating generalized sub‐models into network theory allows to represent the complex screw shapes and material behavior more realistically. Tests on an industrial extruder show close agreement with experiments, outperforming older

Heating rate effect on the thermal properties of thermoplastic polyolefins

open access: yesBudownictwo o Zoptymalizowanym Potencjale Energetycznym
This study investigated the impact of two different heating rates (10 and 20 °C/min) on the thermal characteristics of three specific polymers: high-density polyethylene (HDPE), polypropylene (PP) and polyvinylchloride (PVC).

Impact of Commercial Polyolefin Architecture and Composition on Its Ability to Compatibilize High‐Density Polyethylene/Isotactic Polypropylene Blends

open access: yesJournal of Polymer Science, EarlyView.
This research elucidates the relationship between the molecular structure of commercially available ethylene–propylene copolymers and an ethylene/1‐olefin copolymer and its ability to compatibilize high‐density polyethylene/isotactic polypropylene blends. These findings indicate that the compatibilization of these blends with random copolymers benefits

Impact of Packaging and Recycling Systems on Material Recirculation: A Stage‐Decomposition Model

open access: yesPackaging Technology and Science, EarlyView.
A system‐level view emerges from decomposing recycling into four stages (participation, collection, sorting and process yield), diagnosing constraints and targeting interventions. Cumulative equivalent uses (CEUs) quantify long‐term retention, revealing marginal improvements at high baselines generate disproportionately larger gains than low‐baseline ...
