Popis:	A pilot model of a bio-technical life support system (BTLSS) including human and plant wastes has been developed at the Institute of Biophysics SB RAS (Krasnoyarsk, Russia). This paper describes the structure of the photosynthesizing unit of the system, which includes wheat, chufa and vegetables. The study substantiates the simultaneous use of neutral and biological substrates for cultivating plants. A novel physicochemical method for the involvement of human wastes in the cycling has been employed, which enables the use of recycled products as nutrients for plants. Inedible plant biomass was subjected to biological combustion in the soil-like substrate (SLS) and was thus involved in the system mass exchange; NaCl contained in native urine was returned to the human through the consumption of Salicornia europaea, an edible salt-concentrating plant. Mass transfer processes in the studied BLSS have been examined for different chemical components.
