From waste to worth: optimizing polycarbonate recycling for eco-friendly product development

The production of polycarbonate (PC) waste has become a pressing environmental concern due to the extensive use of PC materials across industries, including automotive, electronics, and construction. Despite its remarkable properties, such as high impact resistance, transparency, and heat resistance, PC contributes significantly to plastic waste accumulation, with only a small fraction currently being recycled. The durability of PC, while beneficial for product longevity, complicates natural degradation processes, leading to persistent waste in landfills and ecosystems. Furthermore, the breakdown of PC can release harmful substances, such as bisphenol A (BPA), posing risks to both environmental and human health. Reducing PC waste through effective reuse strategies not only minimizes landfill overflow but also preserves raw materials and lowers greenhouse gas emissions associated with virgin plastic production. This research investigates the reuse of PC sheets waste through a systematic characterization process, including thermal, molecular and flow analysis, to identify the most suitable recycled materials for eco-friendly products applications. This research identifies the ideal ratios for blending recycled PC with virgin PC to maintain structural integrity and aesthetic appeal. Additionally, the study investigates the feasibility of producing ecological PC with innovative design applications, such as eco-friendly furnishing accessories, emphasizing their mechanical performance and environmental benefits. The aim is to provide an example of ecological management of PC waste to promote circular economy principles, supporting industries in transitioning from linear production models to sustainable, resource-efficient practices, contributing to a greener future for PC applications.
