Description

Plasma-based technologies have emerged as transformative tools in energy storage and environmental pollutant management, gaining significant attention in recent years. Non-thermal plasma, in particular, offers a versatile platform for advanced energy conversion processes and is uniquely suited to integrate with low-cost, renewable electricity sources. This synergy enhances performance while delivering environmental and economic benefits throughout the conversion cycle. To maximize the conversion of greenhouse gases and waste materials, critical scientific challenges must be addressed, including the dynamics of collisions, mass transfer, activation, and control of reactive species at the gas-solid interface in plasma environments. Progress hinges on the development of optimized reactors and highly efficient catalysts tailored for non-thermal plasma applications.
 Despite these advances, several challenges remain, including reactor design, process matching, and the underlying mechanisms governing plasma-driven physico-chemical reactions. Integrated systems combining plasma conversion, catalysis, and separation have received limited attention but represent a promising area for innovation. This presentation highlights recent advancements in non-thermal plasma technologies for valorizing greenhouse gases and plastic waste, contributing to a greener circular economy. Key topics include the optimization of plasma physical processes, the development of gas separation membrane reactors, and the design of integrated plasma-catalysis-separation systems for enhanced efficiency and sustainability.
