Plastic-Waste-Derived Char as an Additive for Epoxy Composite
AI summary Read the abstract
This review examines the use of char derived from pyrolyzed plastic waste as an additive for epoxy composites, summarizing how plastic-waste-derived carbonaceous materials can improve mechanical properties of resins while providing a more sustainable pathway for diverting plastic waste from the environment.
Tremendous amounts of plastic waste are generated daily. The indiscriminate disposal of plastic waste can cause serious global environmental issues, such as leakages of microplastics into the ecosystem. Thus, it is necessary to find a more sustainable way to reduce the volume of plastic waste by converting it into usable materials. Pyrolysis provides a sustainable solution for the production of carbonaceous materials (e.g., char). Plastic-waste-derived char can be used as an additive in epoxy composites to improve the properties and performance of neat epoxy resins. This review compiles relevant knowledge on the potential of additives for epoxy composites originating from plastic waste. It also highlights the potential of plastic-waste-derived char materials for use in materials in various industries.
