Bio‐Polyethylene and Polyethylene Biocomposites: An Alternative toward a Sustainable Future

Macromolecular Rapid Communications, Год журнала: 2024, Номер 45(14)

Опубликована: Апрель 10, 2024

Abstract Polyethylene (PE), a highly prevalent non‐biodegradable polymer in the field of plastics, presents waste management issue. To alleviate this issue, bio‐based PE (bio‐PE), derived from renewable resources like corn and sugarcane, offers an environmentally friendly alternative. This review discusses various production methods bio‐PE, including fermentation, gasification, catalytic conversion biomass. Interestingly, bio‐PE volumes market are expanding due to growing environmental concerns regulatory pressures. Additionally, biocomposites using agricultural as filler materials, highlights demand for sustainable alternatives conventional plastics. According previous studies, addition ≈50% defibrillated abaca fibers into matrix compatibilizer, results highest Young's modulus 4.61 5.81 GPa, respectively. These have potential applications automotive, building construction, furniture industries. Moreover, advancement made abiotic biotic degradation is elucidated address their impacts. Finally, paper concludes with insights opportunities, challenges, future perspectives utilization biocomposites. In summary, can contribute cleaner future.
