Green synthesis and sustainable processing routes

This perspective analyses last year's trends in green synthesis and sustainable processing routes from the viewpoint of the leading emerging industrial directions and needs. After briefly introducing the future scenario, the aspects discussed regard carbon neutrality and defossilization of the chemical industry, electrification of the processes and introduction of low-carbon H₂ routes. Some elements of artificial leaf and solar-to-X technologies, as well as e-chemistry, are also discussed. Trends, opportunities, and personal concerns regarding some directions are presented. The aim is to give clues to analyse this complex topic rather than offer a state-of-the-art and in-depth discussion of the presented examples.
