As a residue of anaerobic compost fermentation, biogas residue is rich in nitrogen, phosphorus, potassium, and other signi cant elements required for plant growth. As well as medium and trace elements such as copper, iron, manganese, and zinc, and its resource utilization can reduce the environmental impact pollution which is of great significance for creating a resource-saving and environment-friendly society. Based on summarizing previous research, the article expounds on the characteristics of biogas residue, the way of resource utilization, sorts out the problems existing, and proposes countermeasures.
