  • ORGANIC MATERIAL REMOVING METHOD AND METHOD OF PRODUCING RECYCLED MATERIAL
    Publication number: 20180371205
    Abstract: An organic material removing method includes a removing step of circulating a heated treatment liquid, in a unidirectional flow, to a plate-shaped composite material containing an inorganic material and an organic material decomposable by the treatment liquid, thereby contacting the heated treatment liquid, in a unidirectional flow, with the plate-shaped composite material to remove the organic material, wherein the composite material is arranged such that the treatment liquid comes into contact with at least a part of a plate surface of the composite material.
