About this Research Topic
The field of process intensification has witnessed a continuous stream of advancements in cost-effective and eco-friendly technologies. The design of novel reactors controlling heat/mass transfer reactions or improving catalytic activities, and the application of hybrid schemes involving hydrodynamic cavitation, ultra-sound, and electro-pulsation, have proven effective for green solvent-based extractions, green waste valorization and wastewater treatments with minimal carbon footprint. Furthermore, the utilization of anaerobic digestion, multi-factor biorefinery processes, and thermos-catalytic reforming has opened new pathways for waste management and renewable energy production, contributing to tangible steps towards sustainability, whereas innovative cold atmospheric plasma uses have shown great potential in agriculture and biomedicine. Despite these remarkable advances, the implementation of process intensification schemes faces obstacles, particularly in terms of upscaling, reliability, and safety, which deter their adoption by small-scale businesses, especially in countries with weak industrial sectors. Additionally, each processing strategy is tailored to specific streams and optimized for outcomes within the economic realities of the stakeholders involved, making universal policymaking challenging. Hence, it becomes crucial to undertake scientific research and critically review available findings to provide evidence-based support for policymakers. By bridging the gap between research and application, we can drive the necessary transformation towards sustainability.
