WIPO Patent Application WO/2010/090218
Kind Code:
A1
Abstract:
Provided is a method for processing a liquid crystal panel to be recycled using subcritical water, and separating and recovering glass and/or transparent electrode material from a liquid crystal panel. The method includes a step of obtaining the state of subcritical water by applying heat and pressure to the mixture of the liquid crystal panel, water and a chemical agent which improves at least one property selected from among the peel property of an organic material from the liquid crystal panel, the decomposition property of the organic material and the resolvability of the organic material. The glass and/or transparent electrode material is separated and recovered from the liquid crystal panel with low apparatus cost, low running cost and low consumption energy by employing the method.
