DISCARDED MATERIAL MANAGEMENT SYSTEM

To provide a discarded material management system capable of grasping a material composition and a carbon footprint of discarded materials including a post-brazing discarded material generated after a brazing step in manufacture of a heat exchanger.SOLUTION: A discarded material management system includes a prediction unit 110 which predicts a change in a material composition of a post-brazing discarded material 215 generated after a brazing process among discarded materials 210 to 215 using brazing condition data and material reception data used in a brazing process of a heat exchanger 200. A management unit 100 grasps, in a real time, a material composition and a carbon footprint of each of discarded materials 210 to 215 on the basis of an amount of discarded component materials 210 to 213 generated in a component processing process, a post-assembling discarded material 214 generated after an assembling process of assembling a component after the component processing process, and discarded materials 210 to 215 including the post-brazing discarded material 215, and the material composition predicted by the prediction unit 110.SELECTED DRAWING: Figure 1 【課題】熱交換器の製造において、ろう付工程後に発生するろう付後廃却材を含む廃却材の材料組成とカーボンフットプリントを把握することができる廃却材管理システムを提供する。【解決手段】廃却材管理システムは、熱交換器２００のろう付工程で使用されるろう付条件データ及び材料受入データを用いて、廃却材２１０～２１５のうちろう付工程後に発生するろう付後廃却材２１５の材料組成の変化を予測する予測部１１０を含む。管理部１００は、部品加工工程で発生する部品廃却材２１０～２１３、部品加工工程の後に部品を組み付ける組付工程で発生する組付後廃却材２１４、及びろう付後廃却材２１５を含む廃却材２１０～２１５の量と、予測部１１０で予測される材料組成と、に基づき、リアルタイムで各廃却材２１０～２１５の材料組成とカーボンフットプリントを把握する。【選択図】図１
