Apparatus for reclaiming glass substrate

An apparatus (10) for reclaiming a glass substrate being conveyed in an approximately horizontally supported state by a conveyor, the apparatus comprising a first alkali solution treatment part (12), an acid solution treatment part (14), and a second alkali solution treatment part (16), the parts (12), (14), and (16) having been arranged in this order in the defective-substrate conveying direction. In the first alkali solution treatment part (12), a defective substrate conveyed from a substrate introduction part (11) is sprayed with an alkali solution to remove the resinous layer which is an uppermost layer. In the acid solution treatment part (14), the defective substrate rinsed in a water rinsing part (13) is sprayed with an acid solution to remove the metallic layer which is an interlayer. In the second alkali solution treatment part (16), the defective substrate rinsed in a water rinsing part (15) is sprayed with an alkali solution to remove the resinous layer which is a lowermostlayer. With this glass su
