PROBLEM TO BE SOLVED: To provide a system of effective utilization of a waste gypsum board in which a processed product is produced with a waste material from the waste gypsum board and the processed product is utilized therein.SOLUTION: There is provided a database which stores: waste information such as types and amount of waste material of waste gypsum boards processed product information such as types and amount of processed products produced with the waste material of the waste gypsum boards and practice information such as types and amount of the processed products to be used in practice sites. The type and amount of a processed product which is required for practice are calculated with the practice information. The type and amount of waste material of a waste gypsum board required for the processed product are determined, and the type and amount are stored. The information regarding the type and amount of the processed product from the waste gypsum board is shared between a discharging company and users so that a user company may effectively utilize the waste material of the waste gypsum board as the processed product produced from the waste material provided by the discharging company in a practice site.COPYRIGHT: (C)2014,JPO&INPIT【課題】廃石膏ボードの廃棄物から加工製品を製造、使用し、廃石膏ボード廃棄物を有効に利用できるようにするシステムに関するものである。【解決手段】廃石膏ボードの廃棄物の種類、数量などの廃棄物情報、廃石膏ボードの廃棄物から作製される加工製品の種類、数量などの加工製品情報、及び、施工現場で使用する加工製品の種類、数量などの施工情報を記憶するデータベースと、施工情報から施工に必要な加工製品の種類、数量を算出し、該加工製品に必要な廃石膏ボードの廃棄物の種類、数量を決定する種類、数量とを備え、排出事業者における廃石膏ボードの廃棄物から製造した加工製品を、使用業者として施工現場で廃石膏ボードの廃棄物を有効に利用できるように廃棄石膏ボードの加工製品の種類、数量の情報を排出事業者と使用者に共有する。【選択図】図1
