Potential improvement in the mechanical performance and thermal resistance of geopolymer with appropriate microplastic incorporation: A sustainable solution for recycling and reusing microplastics
Researchers tested whether microplastics of various sizes could be incorporated into geopolymer, a cement-like construction material, as a way to recycle plastic waste. Adding small amounts of microplastics actually improved the material's strength and heat resistance up to 400 degrees Celsius. This approach offers a potential solution for trapping microplastics in building materials rather than letting them pollute the environment and threaten human health.
