Chapter 7: Patented and Commercialized Ionic-liquid-based Processes for Waste Valorisation

Chapter 7 provides an overview of examples of patented and/or commercialized ionic liquid applications, with particular emphasis on waste valorisation. First, a general overview on the evolution of ionic-liquid-based processes and products within commercial and industrial settings is given. Then, by focusing on waste valorisation applications, a survey of patents available is provided along with representative commercial cases. The production of high-quality chitin and related products from shrimp shells, the ionoSolv and the Ioncell processes, and a new route for polyethylene terephthalate (PET) recycling are highlighted.
