•Need to understand the model
•The model is simplifying the AD process
•No validation of biological parameters
•No information on the effect of inhibitory compounds
•No information on the effect on kinetics in differenttemperature ranges
•Requirement of detailed substrate definition
•The COD flow is rather complex
