A large group of BMP researchers directly addressed this problem during a workshop held in Leysin, Switzerland, in June 2015. The workshop resulted in a new set of guidelines for BMP tests published in 2016, which is the subject of the present commentary. The work has continued with two international inter-laboratory studies and one additional workshop held in Freising, Germany, in 2018. The dataset generated by the two inter-laboratory studies were used to refine the validation criteria for BMP tests. Based on these new results an update to the original guidelines is proposed here.}, language = {en} } @article{HafnerKochCarrereetal.2018, author = {Hafner, Sasha D. and Koch, Konrad and Carrere, H{\´e}l{\`e}ne and Astals, Sergi and Weinrich, S{\"o}ren and Rennuit, Charlotte}, title = {Software for biogas research: Tools for measurement and prediction of methane production}, series = {SoftwareX}, volume = {7}, journal = {SoftwareX}, issn = {2352-7110}, doi = {10.1016/j.softx.2018.06.005}, pages = {205 -- 210}, year = {2018}, language = {en} } @article{HafnerAstalsHolligeretal.2022, author = {Hafner, Sasha D. and Astals, Sergi and Holliger, Christof and Koch, Konrad and Nielsen, Lisa and Refsahl, Lina and Weinrich, S{\"o}ren}, title = {Assessing the value of kinetic results from biochemical methane potential tests: Reproducibility from a large inter-laboratory study}, series = {Cleaner Chemical Engineeering}, volume = {4}, journal = {Cleaner Chemical Engineeering}, issn = {2772-7823}, doi = {10.1016/j.clce.2022.100065}, year = {2022}, language = {en} } @article{JustesenAstalsMortensenetal.2019, author = {Justesen, Camilla G. and Astals, Sergi and Mortensen, Jacob R. and Thorsen, Rasmus and Koch, Konrad and Weinrich, S{\"o}ren and Triolo, Jin Mi and Hafner, Sasha D.}, title = {Development and Validation of a Low-Cost Gas Density Method for Measuring Biochemical Methane Potential (BMP)}, series = {Water}, volume = {11}, journal = {Water}, number = {12}, issn = {2073-4441}, doi = {10.3390/w11122431}, year = {2019}, language = {en} } @misc{HafnerKochCarrereetal.2019, author = {Hafner, Sasha D. and Koch, Konrad and Carrere, H{\´e}l{\`e}ne and Astals, Sergi and Weinrich, S{\"o}ren}, title = {Software for measurement and prediction of methane potential (Poster). 4th International conference on monitoring and process control of anaerobic digestion plants, Leipzig, M{\"a}rz 2019}, year = {2019}, language = {en} } @misc{WeinrichDeloryAstalsetal.2022, author = {Weinrich, S{\"o}ren and Delory, F{\´e}lix and Astals, Sergi and Koch, Konrad and Hafner, Sasha D.}, title = {Simple kinetic models for clear comparison of anaerobic digestion at different scales and operating conditions. 17th IWA World Conference on Anaerobic Digestion, Ann Arbor, USA, Juni 2022}, year = {2022}, language = {en} }
