This laboratory focuses on both basic and applied research, using biomass (including biowaste) to produce biowaste, and the research of the subsequent processes, such as biogas purification. We do modelling and evaluation of the processes of anaerobic transformation of biomass into biogas and digestate, which may both be used in energy production. We provide basic analytical service for biogas stations and we also evaluate biogas technologies. We test methane production from non-traditional substrate. We also investigate the biomass aerobic degradation process, i.e. composting. New bioreactors, especially lower capacity ones, are being developed.
