Key findings: The study is still ongoing, but the abstract indicates that the use of extruded waste recycled plastic as a partial replacement for coarse aggregates in concrete is being investigated.

"Structural analysis and gasification reactivity of coals obtained from slow pyrolysis of extruded coal chips and recycled plastic" (2024) ( Marais et al., 2024 )
Methodology: Coals obtained from slow pyrolysis of extruded coal chips and recycled plastic were analyzed for their structural properties and gasification reactivity.
Key findings: The research is still ongoing, but the abstract indicates that structural analysis and gasification reactivity of coals derived from slow pyrolysis of extruded coal chips and recycled plastic are being investigated.

"Green composites using recycled plastic bags and pineapple fiber waste" (2022) ( Gandara et al., 2022, pp. 1709–1724 )
Methodology: Recycled plastic bags (PEr) were extruded greece telegram data with pineapple fiber waste (PR) to create green composites. The composites were characterized using various methods including FTIR, TGA, mechanical and water absorption tests.

Key findings: The addition of PR to PEr improved the tensile modulus and stiffness of the composites, but reduced the impact strength. The use of a binder had little effect on the mechanical and thermal properties and slightly reduced water absorption.

“ (PCR) from chlorine tank” (2022) ( Thonglor & Charoeythornkhajhornchai, 2022 )
Methodology: High-density polyethylene (HDPE) plastic waste from chlorine tanks in the fisheries industry was mixed with virgin HDPE plastic pellets in various proportions. The thermal, rheological, mechanical and physical properties of the blends were evaluated after extrusion for up to 80 cycles.
Key findings: The thermal properties of the mixtures did not change and 20 recycling cycles were found to be the maximum suitable for PCR without significantly affecting its rheological properties, mechanical properties and product color.

“Preparation of composite materials using recycled high-density polyethylene plastic for railway sleepers” (2023) ( Zhang et al., 2023 )
Methodology: Recycled high-density polyethylene (HDPE), polypropylene (PP), mica, glass fiber and a compatibilizer were extruded and used to produce composite materials for railway sleepers. The mechanical performance and microstructure of the composites were evaluated.
Key findings: Composites containing 62.5% glass fiber and 20% PP demonstrated excellent performance for the production of sleepers, with significant improvements in flexural strength, flexural modulus, tensile strength, compressive strength, and stiffness compared to the original composite materials without glass fiber.
