Objective:
Hydrofluorocarbons (HFCs) and fluorinated polymers (fluoropolymers) are widely used as refrigerants, foaming agents, insulating materials, and coatings. The negative impact of HFCs and fluoropolymers in the environment is under increasing scrutiny. HFCs are potent contributors to global warming, while it has been suggested that fluoropolymers can breakdown into small chain poly(fluorinated) alkyl substances (PFAS), known to be damaging to health. Current methods for disposal of F-gases and fluoropolymers are both highly energy-intensive and costly. Arguably a better approach would involve the chemical recycling of these molecules and materials. This would not only prevent their release into the environment it would also provide an alternative means to source fluorine atoms that does not rely on mining finite mineral resources (e.g. CaF2, fluorspar). Underpinned by ERC StG and CoG projects and more than 10 years of experience in the field, my lab recently developed a breakthrough technology that allows simple, cost-effective method for recycling HFCs and fluoropolymers. In this project, we will translate and commercialise this technology allowing the fluorine content of both HFCs and fluoropolymers to be reused to generate commercially relevant fluorochemicals this activity marks an important step toward a new circular economy for fluorine.
