A whole day and Philips consumer gear hasn't been mentioned!

I've read that one cause of poor flow soldered joints was the steadily accumulative presence of dissolved copper in the bath, resulting in a raised melting point slushy bath with poor adhesion and tendency to dry-jointing. It's understandable that bean-counters would want to keep process going as long as possible with a given charge of solder, but surely there would be provision for salvage return and refinement of what must have been a valuable quantity of alloy?
