Key Points

Fluoride-catalyzed depolymerization effectively converts end-of-life silicones into cyclic monomers, enhancing sustainability.
By altering solvents and volumes, the process can be fine-tuned for greater efficiency, achieving optimal monomer yields.
Chemical recycling methods were systematically assessed, revealing key interactions between catalysts and reaction conditions.
These findings support advancements in recycling technologies, potentially reducing reliance on virgin materials.

Implication

This research investigates the recycling of silicones using fluoride catalysts, suggesting improvements in chemical recycling methods.

Abstract

Recycling end-of-life silicones is of interest due to the high energy cost associated with producing new materials from virgin raw materials. This work explores the chemical recycling of various commercially...
