Biodegradable plastics are a potential sustainable alternative to conventional petrochemical-based non-degradable plastics. Due to their lightweight, flexibility, durability, versatile applications, chemical inertness, electrical and heat insulation, and conductivity, plastics have become an essential material for many industries, with annual production currently exceeding 450 million tons. However, these materials are non-biodegradable, leading to detrimental consequences such as the formation of microplastics from improper disposal and the generation of toxic gases, including furans, dioxins, mercury, and polychlorinated biphenyls, from burning plastic waste. This results in environmental pollution, affecting land, water bodies, and the atmosphere. In response, studies where the focus has been on creating bio-degradable polymers such as polylactic acid, polyhydroxy alkanoates, Polycaprolactone, Poly(butylene adipate-co-terephthalate), and Polybutylene succinate, which were extracted from renewable resources or chemically modified as biodegradable polymers. Biodegradable polymers exhibit a wide range of properties and can now be modified to be used in various applications suitable for substituting some conventional plastic products. Thus, the article highlights the critical issue of environmental pollution caused by non-biodegradable plastics and provides a comprehensive overview of the synthesis processes, properties, novel applications, and challenges associated with the use of biodegradable plastics.
Fire-Retardant Wastepaper Reinforced Waste Polyethylene Composite: A Review
The increase in fire
outbreaks recently and the need for eco-friendly and fire-resistant materials
have inspired a wave of studies, focusing on producing innovative composite
materials with effective fire-resistant properties. This review delves into the
world of fire-resistant wastepaper-reinforced waste polyethylene composites.
Using wastepaper as a strengthening factor in polyethylene matrices, combined
with fire-retardant additives like nanoparticles, introduces a hopeful path for
waste management and improved material properties. This work carefully
considers the combining approaches, physical and mechanical properties,
fire-resistant mechanisms, and environmental impacts of these composites. The
review underscores the possible and potential applications, difficulties, and
prospects of such environmentally friendly materials in various industries.
Understanding these composites’ blending, attributes, and conceivable
utilization is essential for advancing maintainable and fire-safe material innovation
in pursuing a greener future.
