Abstract:

Rice husk is a kind of agricultural waste produced after rice processing, and one of the important biomass resources. Discarding, burying or burning of rice husk in open field directly will cause not only waste of resources but also environmental problems. Resource utilization is the development trend of effective utilization of rice husk, which is in line with the requirements of the sustainable agricultural development and green and circular agricultural development. Material utilization is a new way of rice husk resource utilization, which has become the focus of research at home and abroad. Therefore, on the basis of analyzing the properties of rice husk, this paper took rice husk board, rice husk-polymer composite and rice husk-cement composite as examples, reviewed the research progress on the performance of the composites and the material utilization of rice husk resources. Finally, the development direction of material utilization of rice husk resource was discussed, so as to provide reference for further research.

Key words: agricultural waste, rice husk, material utilization, rice husk board, rice husk-polymer composite, rice husk-cement composite
