Systems and methods for body-proximate recoverable capture of mercury vapor emitted during cremation of human remains having dental amalgam fillings containing mercury. In various embodiments, one or more recoverable mercury sorbent packets comprise a combination of nanoparticles of one or more chalcogens and a particulate refractory material contained in a refractory material packaging. The recoverable packets capture and contain elemental mercury vapor emitted during cremation from dental amalgam fillings containing mercury. The recoverable packets are placed external to the body and within the combustion chamber during cremation, and not within the flue or exhausts exiting the combustion chambers. In various embodiments, the recoverable packets are positioned within the casket or primary combustion chamber, and may be preferably positioned proximate the head and neck of the body with the aid of selectively-refractory containment structures. After cremation, the mercury laden recoverable sorbent packets may be removed from the ashen remains of the body, and optionally the mercury may be recovered and the sorbent packet reprocessed for reuse.
