Abstract

Provided are products of manufacture and methods for the removal of gaseous methane and carbon dioxide, for example, for the removal of environmental or atmospheric or anthropogenically produced gaseous methane and carbon dioxide. Products of manufacture as provided herein comprise living emission abolish filters (LEAFs) for the removal of methane and carbon dioxide, where the “living” component of the “emission abolish filter”, or biofilter, comprises a methane-capturing bioagent, optionally comprising halophilic methanotroph bacterium. Products of manufacture as provided herein are manufactured as arrays, sheets, microfibers and/or microbeads comprising immobilized living, active methane-capturing bioagents, optionally comprising halophilic methanotroph bacterium. In alternative embodiments, the methane-capturing bioagents are enclosed or immobilized in or onto a crystal gel matrix or a nanoshell. Products of manufacture as provided herein can replace gas flares, flare stacks or a gas combustion devices, or are used with a methane scrubbing system.
