Abstract
A method of reducing a concentration of PFAS in a solid waste is disclosed. The method comprises combining the solid waste with an alcohol solution to provide a mixture of a solid phase and a liquid phase in which the solid phase comprises insoluble components of the solid waste and the liquid phase comprises the alcohol solution and at least a portion of the PFAS. The solid phase and the liquid phase are then separated to provide cleaned solid waste and an alcohol solution comprising PFAS.
