Abstract: Systems and methods for producing and extracting a gas from a wastewater fluid including multiple sheets or layers that form a composite membrane. The composite membrane includes a sandwich structure in which a dry matrix layer is surrounded by a first layer including a first immobilized bacteria and a second layer including a second immobilized bacteria. The first immobilized bacteria and the second immobilized bacteria can be configured to produce a gas from one or more compounds in a wastewater fluid. The dry matrix layer can be configured to receive the gas from the first and second layers, and the gas can be extracted from the membrane. The hydrophobic coatings can be disposed between the dry matrix layer and one or both of the first and second layers. An adhesive interface can be disposed between the dry matrix layer and one or both of the first and second layers.
