Diversification of energy supply is generally regarded as desirable, particularly if directed to renewable energy and greenhouse benign technologies. Various opportunities are becoming available for the application of memebrane‐based gas separations, particularly for upgrading landfill gas. Although the trade‐off between permeability and selectivity is an inherent conflict of priorities for the design of membranes, research and development efforts have focused on selecting materials and developing synthesis processes to improve both selectivity and permeability. This paper considers the use of landfill gas as a significant global renewable resource, and the various methane (CH 4 ) purification technologies. The development of materials to enhance membrane‐based gas separations is also discussed.
