Mercury has value although because it's so hazardous the shipping permits for it exceed the value. Nobody in the local area takes it.
Sounds like no one pays for it... Many household products contain mercury, from CFLs to button batteries to some thermometers. While mercury isn’t recyclable, many of these products are. You will likely have to utilize your local household hazardous waste (HHW) facility or events to properly dispose of and recycle items containing mercury.
Call them and ask them. This is a q&a about the place, I'd check the website for their price list
