Founded in 1982, Sun Paper, a Shandong papermaking company, has led the industry's development over the past 30 years and has become one of the leading companies in China's papermaking industry. It is one of the few domestic companies with a diversified business model, implementing integrated forest-pulp-paper projects overseas, and is a leading integrated papermaking company in China with both dissolving and chemical-mechanical pulp.
The company currently possesses world-leading papermaking and pulping production lines, with business covering industrial paper, biomass-based new materials, and fast-moving consumer goods. Its main products include coated paper, uncoated graphic paper, kraft linerboard, household paper, dissolving pulp, and chemical-mechanical pulp. In 2018, the company's annual paper and pulp production capacity will reach 6.02 million tons.
The company pioneered continuous dissolving pulp cooking technology in the industry and extracts xylose and xylitol from hydrolyzate. The company has also applied for patents for the extraction of xylose and xylitol from dissolving pulp wastewater. It is estimated that 200,000 tons of dissolving pulp wastewater can initially yield 20,000-30,000 tons of xylose, truly maximizing the use of wood.
