Scalable biomaterial-based bioreactors are described. In one embodiment, the bioreactor may comprise perforated plates stacked such that the assembled bioreactor has the necessary manifolds and chambers to transport gas and liquids to a biomaterial contained within the bioreactor, and to remove the reaction products. In another embodiment, single use bioreactors are described. Methods of operating the bioreactors are also described.
