Is there a market for calcium fluoride waste products?

Hi peoples!

We are actually developing a wastewater treatment system and we will surely produce a lot of calcium fluoride sludges from our process. Instead of disposing of these wastes into a landfill, I came with the idea it could be possible to recycle these sludges into a sellable product as our wastewater stream species are limited (fluorides and slight amount of sulphates, ammonium and chlorides).

Does anyone knows if there is a market for calcium fluoride sludges coming from wastewaters operations ?

You need to start with your environmental regulatory agency to find out exactly what their regulations are because your waste product is probably an environmentally regulated hazardous waste, and the paperwork and liability may make recycling impractical.

In the U.S. we had a vibrant young "chemical waste exchange" industry 20 years ago, but some bad starts (Times Beach), chemical paranoia, and EPA regs apparently made recycling of waste products so impractical that they killed off that industry. I don't know of any chemical waste exchanges remaining in the U.S., so your question would probably be moot here.

Please excuse a bit of "current-events" humour...

But you can probably sell your waste to the City itself for inclusion in our water supply. Isn't that the usual way to get rid of toxic fluoride-based wastes?

Really, I'm sorry. I couldn't help myself. ;-)
