摘要
This study summarized the current situation of waste paper in papermaking industry, analyzed the impact and challenge of the "Zero Import" policy of solid waste on the supply chain of papermaking raw materials in China. It was proposed that domestic waste paper and imported recycled fiber pulp board will still be an important proportion of China's papermaking raw materials in the future, which is of great significance to ensure the effective supply of fiber raw materials for China's paper industry. On this basis, the technical problems emerged during the high-quality recycling of waste paper fibers in terms of restraining strength performance decay, deinking, bleaching, and stickies control were reviewed, and the scientific research pertaining to the basic theory of waste paper fiber application and innovative solutions to the abovementioned technical problems in recent years were accentuated.
