The article discusses the challenges and opportunities in reimagining plastics waste as an energy solution. It highlights the inadequate recycling measures and environmental threats, particularly in developing nations, and emphasizes the significance of Waste-to-Energy (W2E) and Waste-to-Fuel (W2F) technologies, such as pyrolysis and gasification, for converting difficult-to-recycle plastic waste into dense-energy sources. However, it identifies a critical gap in current research: the emission of CO₂ during these processes. The article advocates for the development of CO₂ capture and utilization technologies to make W2E and W2F methods more sustainable. It also addresses the cultural and economic factors contributing to the rapid accumulation of waste plastics, the global trends in plastic production and waste generation, and the environmental and health impacts of microplastics. The article concludes by discussing innovative solutions like converting waste plastics into textiles, building materials, and 3D printing filaments, and the importance of managing direct CO₂ emissions through carbon capture and storage (CCS) or utilization (CCU). It emphasizes the need for political commitment and collaboration to address transboundary disposal issues and the economic benefits of implementing these technologies in economically disadvantaged regions.The article discusses the challenges and opportunities in reimagining plastics waste as an energy solution.
