Modern biofuel cells for waste recycling in life support systems
Innovative ways of treating urea in waste water reprocessing for long duration space exploration are being considered. Urea is very stable and therefore there are few effective ways for its decomposition. The feasibility of the use of the enzyme urease is to catalyze the hydrolysis of urea to ammonia and carbon dioxide is discussed, including a methodology, potential problems, the capabilities and advantages of such a system.
