In this study, we aim to validate the reaction network with an idealized experiment. We want to show that 1) rate controlling parameters are identifiable from the measured data by inverse modeling, and 2) that this network is able to predict the measured emissions in the experiment given the initial conditions. In the experiment, cabbage is used as substitute for waste, and partial pressures of CO2 and CH4, cumulative production of gas, Volatile Fatty Acid (VFA), NH+4 and pH are measured. Different mass transport limitation between regions of hydrolysis and methanogenesis are imposed on the system. Once validated, the network can be validated for less ideal systems and eventually be used for upscaling. In this conference proceeding, we present in short the biogeochemical reaction network, our experimental set up and discuss the expected experimental results by forward modeling.
