Abstract: Alternative technologies for the microbially mediated biological oxidative transformation (composting) of human wastes and other organic wastes are presented. Batch mode and continuous process composters are proposed to convert waste materials into a form that is a useful input for lunar agriculture. Each composting system provides environmental conditions necessary for composting. The waste materials are composted over a period of time and the resulting composted material is added to an engineered soil in plant growth chambers. Composting technology used in conjunction with a regolith-derived soil for agriculture allows organic wastes to be effectively recovered for re-use in food production.
