I would like to know what other shops are doing with their router dust.
All of our rout dust is separated from our drill dust but some of our
rout dust contains dust from the scoring operation, some is just from
routers. Currently, we ship all the rout dust as hazardous waste
because a sample we took showed 4.9 ppm lead which is right at the
maximum limit allowed of 5 ppm. We are thinking about taking other
samples from both of our collection containers (one with just rout dust
and the other with rout/scor dust) to see what the lead content
currently is in each but are wondering if it would be worth the trouble
just to see if we can get it reclassified as non-hazardous waste.
Thanks for your response.

Allen,
Because we plate a fair amount of gold, our router dust has some value
for being reclaimed. We send it to Hallmark Refining (north of Seattle,
WA) for gold reclaim. We pay about 0.75 $/lb for the processing and
then the gold value is used to offset the processing cost. Sometimes we
make money and sometimes we pay a little.
After the gold has been removed, the residues are sent to someone like
ASARCO or NORANDA for further processing for lead and other metals. The
utility of this process to you would be based on how much gold you plate
(and then route through!)
