I have been working in the biogas area for 25 years with applied research, by example technical and system evaluation for biogas plants. The work has been realized in pilot scale, farm scale and co-digestion plants with digestion of slaughterhouse waste and other industrial waste, sludge from municipal wastewater plants or pulp- and paper mills, food waste, manure and energy crop. Focus has been on pre-treatment as disintegration, and thermal hydrolysis as mixing of digester, post treatment of digestate by mechanical separation and evaporation and the energy and mass balances for the biogas plant.
I have also been working with bioethanol production from sugar beets.
