“…The consecutive technological subsystem of physical-chemical treatment of biological wastes for obtaining nutrient solutions for growing cultivated plants on hydroponics, developed in IBF SB RAS with respect to closed ecosystems of space purposes, consists of three main reactors: "wet incineration", urea decomposition and H2O2 synthesis. A simplified scheme of the technological process is shown in Figure 1 [3,7,8]. The method of biowaste fertilizer preparation for phototrophic link of closed-loop LSS uses nitric acid HNO3 due to its synthesis in the existing chain of LSS circular processes and alkali -KOH due to its predominance in urea dialysis products [9].…”

The integration of closed biotechnological cycles in life support systems (LSS) of autonomous transport systems (ATS) is a critical solution for deep space and planetary exploration. Prolonged autonomous existence of integral ecosystems depends on the degree of cyclic use of substances and the coefficient of closure of the ecosystem's mass-exchange processes. In missions lasting over two years, it becomes more beneficial to reproduce necessary substances inside the system instead of relying on external supplies. This research aims to explore the integration of closed biotechnological cycles, with a focus on the biotechnological cycles of methane and carbon dioxide, in the LSS ATS to achieve a high coefficient of closed circulation of substances and nature-like features. Two methods of ATS crew waste processing are described, and the potential of using methane for additional oxygen generation and food protein biosynthesis in the closed-loop cycle of substances transformation is investigated. Additionally, the possibility of applying methane biooxidation technology to existing biotechnological processes of feed and food protein production using methanotrophic bacteria in terrestrial conditions is discussed as a potential method for producing food animal protein in LSS ATS.
