Abstract
A method for recovering resin from a fiber-reinforced resin provides a resin recovery method including the steps of: dissolving a resin contained in the fiber-reinforced resin in ethylene glycol, solid-liquid separating into a solution in which the resin is dissolved in ethylene glycol, and fiber, heating concentrating the solution to obtain a concentrated liquid, and cutting the concentrated liquid, in which upon heating concentration of the solution, the solution is concentrated at a temperature at which the resin contained in the concentrated liquid is melted, and the resin contained in the concentrated liquid to be cut is melted.
