Space Habitat Waste-to-Biogas Digester

A crewed deep-space habitat can't afford to treat organic waste as dead weight — this simulator models an anaerobic digester that turns food scraps and other biomass into usable methane. Real first-order microbial kinetics, an Arrhenius temperature law and a C:N-ratio inhibition curve drive a live 3D tank where rising bubble instances trace the biogas production rate itself. Tune feed rate, temperature, retention time and feedstock C:N ratio and watch the biogas yield, methane fraction, recoverable energy and volatile-solids degradation respond exactly as the underlying kinetics dictate.
