Abstract
Provided is a method for recycling supercritical waste liquid generated during a process of producing a silica aerogel blanket, and a method for producing a silica aerogel blanket reusing supercritical waste liquid recycled thereby. The method for recycling supercritical waste liquid and the method for producing a silica aerogel blanket reduce the production costs and prevent the deterioration in thermal insulation performance of a silica aerogel blanket by adding a metal salt to the supercritical waste liquid by the recycling method.
