voc free flux

What do you guys do with your old, used VOC free flux?

Can you just send it down the drain? Or is it considered hazardous, and should be disposed of accordingly?

Thanks for your replies.

As a minimum, you should observe the recommendations for disposal in your flux supplier's MSDS. For one VOC-Free Flux, the MSDS says something like:

Waste Disposal Methods: Scrap material may be disposed of, by a licensed waste disposal company or incinerated, following Federal, State and Local regulations.

Absolutely, read the manufacturers MSDS. You do have it, don't you? We use Kester 971 and it reads Waste Disposal Methods: According to local regulations. Considered biodegradable. We did take the precaution of informing the local authorities and having a site inspection to explain our process and materials. As a result of this we have a letter authorizing direct discharge into the city sanitary sewer system. John Thorup
