The objective of the present study is to develop anaerobic co-digestion process which satisfies features required to achieve sustainable development by adjusting the component of feedstock and modelling of anaerobic digestion process. Three features were proposed for waste treatment that were processing capacity, energy production capacity and stability. There were analyzed from the viewpoints of the mass circulation, the biogas yield and the modelling of anaerobic digestion process respectively. The developed process fulfilled the processing capacity and the energy production capacity because the feedstock made from food waste and paper had high total solid content and optimal C/N ratio. The mathematical model of anaerobic digestion process was developed to describe the dynamic behavior of anaerobic digestion process. Applying the model and the estimated parameters to the experimental period, the model revealed the fermentation state and predicted biogas yield accurately.
