These research lines cover novel technologies for resource recovery (e.g. N- and P from urine), as well as microbial desalination processes. So far, our team has achieved remarkable progress with stabilizing urea from urine via both electro-membrane systems, as well as with bioelectrochemically assisted tecniques. Moreover, details on microbial desalination kinetics and energetics was thoroughly presented. The research is supported by the János Bolyai Research Scholarship of the Hungarian Academy of Sciences (HAS).
Electro-fermentations are electrochemically assisted fermentations systems, in which the present electrochemical environment supports higher product yield, selectivity and kinetics. Although it is a quite new area of bioelectrochemical systems, its potential is beyond question in various technologies, such as enhancing dark fermentation of waste, or pure culture fermentation of ethanol, lactic acid, etc.
Oxidative electrolysis of fermentation-based organic acids result in value-added components, such as alkanes, alkenes, esters, alcohols, aldehydes, etc. The so-called Kolbe-electrolysis of medium chain carboxylic acids aims to produce mainly alkanes, which could be utilized as fuels / fuel additives. A 1-year research project (EKÖP) on this topic was funded by the National Research, Development and Innovation Office in Hungary.
Cellulose ionogels are formed with the interaction of cellulose and ionic liquids. Such solid materials can be formed with novel properties, such as flexibility, high ionic conductivity, unique mass transfer properties. Starting from 2025, a 4-year long research project (Starting_24 of the National Research, Development and Innovation Office in Hungary) has been funded for the investigation of using cellulose ionogels as novel selective membrane materials in Microbial Fuel Cells and Microbial Electrolysis Cells.
