Oh, I think it's stretching a bit to call it recycling, but it was nice of
them to tell you.
Most people over-skim their pots and "dross" usually contains a significant
amount of good metal. There are a number of mechanical devices which rely on
this and work by squeezing out the metal to get it back. 
A little while back someone or other promoted a new chemical additive for
aiding this process. Bemusingly, at least for me, there was quite a lot fuss
about this as I remember, including on this forum. I think one supplier even
got an award for it. Actually none of this is new - just another example of
recycling. These products/techniques were common from the earliest days of
wave soldering.
Footnote.
Ironically, the money/credit they get for their dross will go down
dramatically, as it really will be dross. [Assuming their recycler/supplier
has been playing an honest game with them.]

Subject: Re: [TN] Recycled solder?

My understanding is that they will do the recycling themselves, on site.
They said the recycling would be mechanical, not chemical, so maybe it is
just squeezing out the droww.  They also said it was an effort to be
environmentally conscious, but they are in China, so I'd think it's really
cost.

We are among their smaller customers, so I can't make a lot of demands.
They asked if we would accept boards made with recycled solder.  I suppose
the best I can do is reply with a list of concerns and ask for test results.

Thanks!

Pete
