Outline of Final Research Achievements

Semi-arid land in Central Asia has been facing an environmental problem in reducing crop productivity due to salinization, caused by climate change and poor irrigation control. The salts in the salinized soil are mainly Na2SO4 or NaCl in Uzbekistan (Na2SO4: 28 %, NaCl: 23 % accounted for the land). The option to improve the soil condition in FAO guideline was to cultivate salt-accumulating plants.In this study an anaerobic digestion system was performed to evaluate the degradation of such plants to obtain biogas whilst separating the saline supernatant from the solid fraction.
Salt-accumulating plant biomass at 70 g/L concentration could be degraded by two distinct AD reactors being fed NaCl and Na2SO4-NaHCO3. Kinetic parameters were estimated by simulating experimental data-sets using a developed model. For the NaCl system 65 % of the fed COD was converted to methane gas, whereas 54 % in the Na2SO4-NaHCO3 system was converted to methane and another 11 % was observed to be sulfide.
