The use of Calciment to treat heavy metal containing waste is described by the EPA as pozzolanic stabilization or fixation. This process has been specified as the "Best Demonstratable Available Technology" (BDAT) for treating heavy metal waste as required by the RCRA Land Disposal Ban. In this process the alkalinity or pH is adjusted so heavy metals are rendered insoluble. Cementing reactions which further reduce leachability as determined by the TCLP test.

Calciment is used at commercial waste treatment facilities, landfills, private and Superfund sites where waste fixation is required.
