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1990年代以来，对实验室化学废物管理的关注就变得越来越重要。为了更好地管理实验室产生的化学废物，建议管理人员鼓励合作与交流的环境，从而重新使用化学试剂。所研究的机构实施了化学废物交换，其目的是捕获超过其有效期的试剂，这些试剂将被丢弃，并在内部供其他地区甚至其他机构使用。内部总共重复使用了1075种试剂，并向外部机构捐赠了4382项物品。在财务数据方面，2011年至2018年，内部经济为16,700.70美元，外部机构为62,633.11美元。在根据目的地比较废物再利用时，内部地址与外部地址相比有显着差异。某些类别的试剂具有更高的附加值，并且在重复使用时可提供更大的收益。通过化学废物交易所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；经济效益取决于材料的市场价值；所采用的策略避免了从大自然中去除原材料以生产新试剂的需要，并减少了与处理有关的费用和符合环境要求的最终目的地。通过化学废物交易所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；经济利益取决于材料的市场价值；所采用的策略避免了从大自然中去除原材料以生产新试剂的需要，并减少了与处理有关的费用和符合环境要求的最终目的地。通过化学废物交易所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；经济利益取决于材料的市场价值；所采用的策略避免了从大自然中去除原材料以生产新试剂的需要，并减少了与处理有关的费用和符合环境要求的最终目的地。
