Cyanide Filter Disposal

How are copper cyanide tank filters handled for disposal by most platers.

(1) Are they just accumulated and hauled away as some kind of F007+ coded hazardous waste

(2) Do they get treated in some kind of cyanide destruct to become decharacterized waste to be hauled off with other noncyanide tank filters and or non cyanide sludge.

Any Info appreciated.

Unless you had some method to mechanically cut up and otherwise triturate the filters, it would be unwise to try and destroy the cyanide and try to throw the filters into the trash.

I suppose someone, somewhere is throwing them in the dumpster, but I only know of the ones who fill drums up for proper disposal as in (1) of your letter.

Also, technically, you are classified differently (from the DEP standpoint) when you process the filters that way, I'm not sure of the logic, but there may be some sense in it, since it requires process control and documentation.
