This KCl by-product often contains unreacted KF and organic solvents, complicating recycling efforts and leading to its classification as waste salt. Conventional methods for managing this waste salt typically involve landfilling, outsourcing treatment, and on-site regeneration. However, landfilling poses significant environmental risks, while outsourced treatment can incur substantial costs. In this context, on-site regeneration of KCl emerges as a promising solution that balances economic feasibility with environmental sustainability, underscoring the pressing need for innovative approaches to waste management in the fluorine chemistry sector.
