Abstract: Furfural residue is the biomass waste in the process of furfural industrial production. In this paper, the sources and composition characteristics of furfural residue are firstly introduced. On this basis, the researches of furfural residue in the fields of biomass energy, composite materials, fine chemicals and agricultural supplies are reviewed, and the research progress in various application fields is analyzed and summarized. Finally, according to the characteristics of furfural residue, the existing problems and challenges in the application of furfural residue are pointed out and the high-value utilization of furfural residue are also prospected.
