Effect of different waste recovery systems on the overall waste generation rates for an Advanced Life Support System
This work demonstrates how studies of life support systems can be used to advance the understanding of environmental principles. Efficient waste recovery systems that are developed for the Advanced Life Support System used in space explorations can be utilised on Earth. As an example, we explored three different ALSS scenarios, each having different waste recovery technologies. The results are compared in terms of the overall waste generation rates. It is concluded that physicochemical waste recovery systems, with their low level of uncertainty in operating conditions and high recovery efficiencies, are the best choice for a 600 day mission to Mars.
