Abstract: This disclosure includes a gas-permeable element formed or at least partially placed in a packaging or medical device containing sensitive or odorous products for regulating an atmosphere in the packaging or medical device. The gas-permeable element includes an active structure formed from a mixture including particles of an active material, and a fibrillated polymer as a binder. The fibrillated polymer is a polymer to which shear has been applied which holds the active material by entanglement. The gas-permeable element includes a molded thermoplastic gas-permeable envelope surrounding the active structure in fluid communication with the atmosphere of the packaging or medical device in which the gas-permeable element is placed. Also disclosed is a method of manufacture of the gas-permeable element.

Abstract: 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.
