However, only scarce information on the development of initial nutrient and heavy metal loads during processing is available. Therefore, this study investigates properties of source-separated MOW during treatment in a semi-industrial scale two-stage biogas plant and subsequent digestate composting including impurities removal. Data from 15 batch experiments was investigated by material and substance flow analysis. Results of this study have shown that about 40\% of nutrients contained in the MOW inflow are mineralized during anaerobic and subsequent aerobic treatment. A higher nutrient release was observed during the anaerobic treatment step. Additionally, impurities removal causes a significant reduction of final nutrient content. Heavy metal analysis confirmed a high heterogeneity of contamination levels. However, digestion and composting do not seem to significantly impact on total heavy metal loads in the substrate flow.}, language = {en} } @inproceedings{BurkhardtJordanHeinrichetal., author = {Burkhardt, Marko and Jordan, Isabel and Heinrich, Sabrina and Behrens, Johannes and Ziesche, Andre and Tietze, Michael and Busch, G{\"u}nter}, title = {Long term and demand-oriented biocatalytic synthesis of highly concentrated methane in a trickle bed reactor}, series = {Progress in Biogas IV - science meets practice, abstracts booklet of the international conference 8th-11th March 2017, University of Hohenheim, Stuttgart, Germany}, booktitle = {Progress in Biogas IV - science meets practice, abstracts booklet of the international conference 8th-11th March 2017, University of Hohenheim, Stuttgart, Germany}, publisher = {FNBB}, address = {Kirchberg an der Jags}, isbn = {978-3-940706-09-6}, pages = {84 -- 85}, language = {en} } @misc{BurkhardtHornTietzeetal., author = {Burkhardt, Marko and Horn, Oliver and Tietze, Michael and Niebling, Falko and Busch, G{\"u}nter and Hilse, Hagen}, title = {Biological methanation - economic feasibility and the next step by the anaerobic bio-reactive wall process (ABRW)}, series = {Conference proceedings - 10th International Conference on Renewable Energy Gas Technology}, journal = {Conference proceedings - 10th International Conference on Renewable Energy Gas Technology}, editor = {Held, J{\"o}rgen}, address = {Lund}, isbn = {978-91-981149-9-7}, pages = {42 -- 45}, language = {en} } @misc{HornTietzeNieblingetal., author = {Horn, Oliver and Tietze, Michael and Niebling, Falko and F{\"o}rster, Wenzel and Wolf, Martin and Hilse, Hagen and Nissen, Dirk and Nissen, Bernd and Lorenzen, S{\"o}nke and Szeimies, Martin and Vith, Wiktoria and Busch, G{\"u}nter}, title = {The WeMetBio2 project - construction, operation and evaluation of a pilot plant for biological methanation in northern Germany}, series = {Conference proceedings - 11th International Conference on Renewable Energy Gas Technology, 20-21 May 2025, Weimar, Germany}, journal = {Conference proceedings - 11th International Conference on Renewable Energy Gas Technology, 20-21 May 2025, Weimar, Germany}, editor = {Held, J{\"o}rg}, publisher = {Renewable Energy Technology International AB}, address = {Lund}, organization = {Renewable Energy Technology International AB}, isbn = {978-91-527-8377-1}, pages = {107 -- 108}, abstract = {Project presentation on the planned implementation of biological methanization using the patented trickle bed process on a farm in northern Germany.}, language = {en} }
