Research progress on furfural residues recycling: A literature review

Millions of tons of furfural residues from the furfural industry are produced every year in China. Proper recycling of these residues is highly desirable as it may reduce associated environmental problems and increase the economic viability of the furfural industry. Research progress on furfural residues recycling is reviewed. The residues have high potential for agricultural applications such as organic fertilizers, soil conditioners, artificial soil and culture media, as well as for the production of activated carbon, bioenergy, and for biobased chemicals such as ethanol.
