Recently, soaring global silver prices have ignited a seemingly niche yet profitable industry—the recycling of medical CT waste films. Since traditional CT films are coated with a silver-based photosensitive layer, the surge in silver prices has significantly increased the value of recycling these waste materials, with prices in some regions even doubling.Previously, discarded CT films from hospitals were often treated as general waste or left idle. However, silver is a precious metal with strong demand in electronics, solar energy, jewelry, and other fields. After extraction and purification, it retains substantial economic value. Specialized recycling companies now use chemical processes to extract silver from the films, reducing resource waste and generating additional revenue for medical institutions.This trend highlights the sensitivity of the precious metal recycling market. Tight global silver supply and growing industrial demand have driven up silver prices, turning silver-containing waste into a valuable resource. It is important to note that such recycling activities must comply with environmental regulations to avoid secondary pollution. If silver prices remain high, the recycling of waste CT films is likely to continue gaining momentum.
近期，国际银价持续攀升，带动了一个看似冷门却利润可观的行业——医用CT废胶片回收。由于传统CT胶片表面涂有含银感光层，随着白银价格暴涨，废胶片的回收价值也水涨船高，部分地区回收价格甚至实现翻倍增长。过去，医院产生的废旧CT胶片多作为普通废品处理，或堆积闲置。然而，白银是贵金属，在电子、光伏、珠宝等领域需求旺盛，回收提纯后仍有较高经济价值。目前专业回收企业通过化学方式提取胶片中的银，既降低了资源浪费，也为医疗机构创造了额外收益。这一现象也反映出贵金属回收市场的敏感性。全球白银供应紧张及工业需求增长推动银价走高，进而使得含银废弃品“变废为宝”。需要注意的是，此类回收活动需符合环保规定，避免二次污染。未来，若银价保持高位，废胶片回收行业或将继续升温。
