Dispose according to the MSDS for the product. As a point of comparison, here is a MSDS for another flux: http://www.kester.com/MSDS/USA%20and%20Canada/English/Fluxes/MSDS%20135%20US%20(24Nov03).pdf

... which says: 13 Disposal considerations Product: Recommendation: Must not be disposed of together with household garbage. Do not allow product to reach sewage system. Uncleaned packagings: Recommendation: Disposal must be made according to official regulations.

We collect our liquid flux in a barrel and periodically have it carted by a hazardous disposal firm.

How about just posting who it is? If it is no cost then this would not be aproblem and everyone can benefit.

We're not sure about the application of powder flux for original poster to this thread, but a common application of powder flux is in brazing. This powder flux can be either metal bearing or just flux.

As an aside: Soldering and brazing are joining processes where parts are joined without melting the base metals. * Soldering filler metals melt below 840*F. * Brazing filler metals melt above 840*F.
