Abstract: With the implementation of waste classification, the generation amount of wet waste has been increasing. The wet waste mainly consists of household kitchen waste and food waste, both often treated by anaerobic digestion. During the waste sorting process, some paper towels may be mixed with wet waste and enter the anaerobic digestion system. The impact of low-dosage paper (5%, measured in TS) on subsequent individual and co-anaerobic digestion of kitchen waste and food waste was investigated. The results showed that the addition of paper increased the cumulative biogas production by 5.8% and 4.5% for kitchen waste and co-digestion groups, respectively. It also promoted an increase in NH4+-N concentration and pH recovery. In addition, it caused an increase in the relative abundance of cellulose-degrading bacteria, promoting the degradation of cellulose in the paper. Therefore, the mixture of some paper towels could promote the anaerobic biogas production performance of wet waste, so it may not be necessary to completely remove paper during waste classification process.
