有色金属废料的短缺迹象正在增强 在日本，铝废料的价格正在上涨。由于建筑物拆除工程的停滞，废料的产生正在减少。有声音提到了中 资企业的增加。在与中资企业的废料争夺战中，日本国内企业落败的情况很多…… 经营铝废料的东京铝中心（东京江户川区）的社长江川壮一看着厂区内喃喃自语。"装载废料的卡车的 进出明显减少，越来越冷清了"。他说，在雷曼危机时，由于制造业萧条，废料多到几乎无处可去，但 如今即使提高收购价格也很难确保货源。 以日本关东地区为中心开展业务的铝废料批发商组成的团体——轻金属同友会的数据显示，2024年会员 企业的交易量同比减少3.4%，连续3年减少。2025年"交易量仍在持续减少"（轻金属同友会的会长藤原 秀也）。 背后原因是废料的产生正在减少。由于劳动力短缺，日本老旧建筑物的拆除工程推进缓慢。2025年叠加 酷暑，拆除工程陷入停滞。在易拉罐材料方面，受4月啤酒类涨价的影响，出货量减少，空罐的产生量 也随之下滑。 制造企业在内部回收利用有色金属废料的趋势正在扩大，这使得流入市场的废料的减少。从可循环经济 和去碳化的观点来看，有色金属废料不可或缺。例如，日本铝压延大型企业UACJ提出方针称，将推进 从公司内 ...
