Waste treatment integration in space.
The circumstances and criteria for space-based waste treatment bioregenerative life-support systems differ in many ways from those needed in terrestrial applications.  In fact, the term "waste" may not even be appropriate in the context of nearly closed, cycling, ecosystems such as those under consideration.  Because of these constraints there is a need for innovative approaches to the problem of "materials recycling".  Hybrid physico-chemico-biological systems offer advantages over both strictly physico-chemico or biological approaches that would be beneficial to material recycling.  To effectively emulate terrestrial cycling, the use of various microbial consortia ("assemblies of interdependent microbes") should be seriously considered for the biological components of such systems.  This paper will examine the use of consortia in the context of a hybrid-system for materials recycling in space.
