Concern over the management of chemical wastes from laboratories has been gaining importance since the 1990s. For a good management of chemical wastes generated from laboratories, it is recommended that managers encourage an environment of cooperation and exchange, thus reusing chemical reagents. The institution under study implemented the Chemical Waste Exchange, whose objective is to capture reagents past their expiry dates that would be discarded and make them available internally to other areas or even to other institutions. A total of 1075 reagents were reused internally and 4382 items were donated for external institutions. As for financial data, between 2011 and 2018, the internal economy was US$16,700.70 and for external institutions it was US$62,633.11. When comparing the waste reuse according to the destination, an internal address showed a significant difference when compared with the external use. Some categories of reagents have greater added value and provide even greater benefits when reused. The strategy of capturing and making available expired reagents through the Chemical Waste Exchange is positive; it helps the management of the waste generated; the economic benefit will depend on the market value of the material; the adopted strategy avoids the need to remove raw material from nature for the production of new reagents and reduces the costs related to treatment and environmentally appropriate final destination.
自 20 世纪 90 年代以来，人们越来越关注实验室化学废物的管理。为了实现实验室化学废物的良好管理，建议管理人员鼓励合作和交流的环境，从而再利用化学试剂。本研究机构实施了《化学废物交换》，其目的是捕获过期的试剂，这些试剂将被丢弃，并在内部提供给其他区域，甚至是其他机构。共有 1075 种试剂在内部被重复使用，4382 件物品被捐赠给外部机构。就财务数据而言，2011 年至 2018 年期间，内部经济为 16700.70 美元，而外部机构为 62633.11 美元。当根据目的地比较废物再利用时，与外部使用相比，内部地址存在显著差异。一些试剂类别具有更高的附加值，再利用时会带来更大的好处。通过《化学废物交换》捕获和提供过期试剂的策略是积极的；它有助于管理产生的废物；经济效益将取决于材料的市场价值；所采用的策略避免了为生产新试剂而从自然界中提取原材料，并降低了与处理和环境适宜的最终处置相关的成本。
