Development of closed life support systems for water recovery, oxygen generation and food processing is achievable in the future. However, currently the possibility of partial reproduction of food components from metabolic products and biocomplex waste should be taken into account when advanced life support system development is under consideration. Studies on carbohydrate synthesis from products of life are of particular interest because carbohydrates hold the first place in terms of mass in the food. The paper discusses possible ways of carbohydrate synthesis by physical/chemical means. Separate stages of a carbohydrate synthesis process are considered.

The Regenerative Atmosphere Revitalization and Monitoring system (ARMS), been part of Integrated Life Support System (ILSS), is intended for maintenance in the manned modules of a necessary chemical composition of an artificial gas atmosphere (AGA) on base of the crew metabolism product transform to environment initial components. Generally, the ARMS structure includes the individual systems and units intended for: → oxygen generation; → carbon dioxide removal and it concentration; → trace contaminants removal; → carbon dioxide reduction with the goal to produce an additional quantity of water necessary to increase the degree of the oxygen loop clousure. The ARMS structure of the International Space Station (ISS) Russian Segment (RS) includes the Electron-VM Oxygen Generation System (OGS), Vozdukh Carbon Dioxide Removal System (CDRS) and SBMP Trace Contaminants Removal Means (TCRM) installed in the Service Module.
