The common kitchen waste treatment methods include incineration, landfilling, anaerobic digestion, and composting. Anaerobic digestion can generate bioenergy (biogas), and thus has grabbed great interest. However, odor emission is a great concern as it causes public complaints. Biological method for odor control is green and cheap. In this study, related papers have been collected and analysed with VOSviewer. The important research direction has been identified by deeply revealing the study focus and the research results. It has been found that the bioenergy production rate is highly associated with kitchen waste composition and anaerobic digestion conditions. Moreover, it can be seen that the addition of an agent in the digestion could prevent odor generation. For external odor emission control, bio-tricling is more suitable compared to others. This paper has reviewed the anaerobic digestion of kitchen waste for bioenergy production and its odor emission, as well as the currently used biological methods for odor gas emission control.
