Upcycling Waste Polyoxymethylene to Value-added Chemicals Using Reusable Polymeric Acid Catalysts at ppm Levels

Key Points

• This research aims to upcycle waste polyoxymethylene into valuable chemicals using reusable catalysts.
• Used m-phenolsulfonic acid-formaldehyde resin as a polymeric heterogeneous catalyst.
• Employed biomass-derived alcohols and amines in the upcycling process.
• Successfully generated multiple value-added chemicals, including solvents and herbicides.
• Demonstrated the potential for low-level (ppm) catalyst effectiveness.
