我也有看到Q7的文件,如下:
14.4 Recovery of Materials and Solvents
14.40 Recovery (e.g. from mother liquor or filtrates) of reactants, intermediates, or the APIis considered acceptable, provided that approved procedures exist for the recoveryand the recovered materials meet specifications suitable for their intended use.
14.41 Solvents can be recovered and reused in the same processes or in different processes,provided that the recovery procedures are controlled and monitored to ensure thatsolvents meet appropriate standards before reuse or co-mingling with otherapproved materials.
14.42 Fresh and recovered solvents and reagents can be combined if adequate testing hasshown their suitability for all manufacturing processes in which they may be used.
14.43 The use of recovered solvents, mother liquors, and other recovered materials shouldbe adequately documented.
其中相对恰当的是14.41这点上,但是其涉及的是solvent,不是solution,不是liquor,我不知道是否是大家对于溶剂套用的误解????确实按照你们这种直接套用的方式,如果不建立标准,你如何控制每批直接套用的一致性??即使建立标准,那么是否会存在两套工艺,比如第一批,或者第十六批是使用的新鲜溶剂,而在期间的所有批次这是用的是套用溶剂,不同批次之间的溶剂系统都存在不一致,工艺的控制能一致???不知道楼主现在公司还是采取这种方式吗??国外认证或者国外客户审计有提出挑战没???非常感谢你的回答!!@石头968 @意林枫 @hongwei2000@蒲公英 @大呆子 还有各位大神讨论一下。
我个人认为需要区分几个概念,recycle,recover和reuse三个概念.
