Innovative Approaches to Address Plastic Pollution

This technical report outlines various innovative methods developed by researchers at NTU Singapore to tackle the pressing issue of plastic pollution. The report discusses the environmental impact of plastic waste, particularly focusing on e-waste and single-use plastics, which are difficult to recycle. It describes a method where discarded e-waste plastics, specifically acrylonitrile butadiene styrene (ABS), are repurposed to create a synthetic matrix for culturing cancer spheroids. This approach not only reduces plastic waste but also enhances biomedical research. Additionally, the report details a process for converting hard-to-recycle plastics into solid carbon and hydrogen additives for polymer foams, which can improve material properties and provide fuel. Furthermore, it presents a greener method for breaking down plastics using light-emitting diodes and a catalyst at room temperature, resulting in valuable chemical compounds. These advancements contribute to the circular economy and offer sustainable solutions to the plastic waste crisis.
