Pulping and papermaking industry of China has always been facing the shortage of fiber resources. Even worse, with the implementation of the restriction policy on importing solid waste from abroad, the gap of fiber raw material in papermaking industry is further increased. In recent years, high yield pulping has attracted more and more attention because of its advantages, such as wide adaptability of raw material, high compact process, and low investment in equipment. In this paper, the high yield pulping method was firstly introduced, its characteristics in terms of pulping process and fiber slurry were discussed, and the development status of high yield pulp (HYP)was analyzed. Then, the application research progress of HYP was systematically discussed. To be specific, the application status of HYP in traditional paper and paperboard was summarized, and it was emphasized the high-value application of HYP in moulded pulp packaging material, higher value-added paper products, functional composites, and high-performance paper-based materials. Finally, the development of HYP by considering its process improvement and the demand of paper-based functional materials was forecasted.
