ClearAcoustic and thermal characterization of a novel sustainable material incorporating recycled microplastic waste
Researchers created a new eco-friendly foam material by embedding recovered marine microplastics into a bio-based matrix, producing an open-cell insulating material with strong acoustic and thermal properties. The innovation offers a potential path to upcycle hard-to-recycle mixed marine plastic waste into useful building and industrial insulation products.

Development of a Non-Structural Prefabricated Panel Based on Construction and Demolition Waste for Sustainable Construction
This study developed a prefabricated non-structural building panel by combining recycled microplastics with construction and demolition waste in mortar, finding that a 20% construction waste blend achieved compressive strength above 31 MPa and that panels with recycled materials showed up to 39 dB sound reduction and 21°C thermal improvement. The research demonstrates a practical pathway for diverting microplastic waste from the environment by incorporating it into building materials. Using microplastics as a construction input could help reduce both plastic pollution and the environmental footprint of the construction industry.
