In recent years, the Chinese Academy of Forestry Research Institute of Forest Products Chemical Industry researcher, doctoral supervisor Fang Guigang in the field of pulp and paper fruitful, he led the team dedicated to research, sharpening deep plowing, opened up the high yield clean pulp industry in China's independent road, so that China's pulp and paper technology to the world.

Among the many honors, Fang Guigang's most important is the "key technology and industrialization of high-yield clean pulp production of mixed materials" project he presided over, which won the second prize of the 2019 National Science and Technology Progress Award.

"This is the highest honor in my personal research career." Fang Guigang said that this technology has overcome the worldwide common problem of making high-quality chemical-mechanical pulp from mixed materials, and the independently designed clean pulping production line has broken the situation of complete dependence on imports of high-yield pulping equipment, laying a solid foundation for China's clean pulping technology with independent intellectual property rights to go global and making China's pulp and paper technology impressive to the world again.

Dive into the pulp and paper clean technology

In March 1989, at the age of 23, Fang Guigang graduated from the Northwest Institute of Light Industry with a master's degree and was assigned to the Institute of Forestry and Chemical Industry, Chinese Academy of Forestry. From a young man with a dream to an international expert, he has been tirelessly exploring the road of scientific research for 33 years.

Fang Guigang said, "Scientific research is an indispensable part of my life, and I can reach the realm of forgetfulness when I work." He often says: "Treating technical problems, we must adhere to a rigorous attitude, we cannot pretend to know if we don't understand, and we must try to make ourselves grow into insiders."

It is with this spirit of hard work and rigorous academic attitude that he keeps reaping results on his journey to the peak of scientific research on clean pulping technology.

Fang Guigang has continuously presided over the national science and technology support (key R&D) projects from the 8th Five-Year Plan to the 13th Five-Year Plan, the national "948" project, the Natural Science Foundation inclined project, and more than 30 international cooperation projects. He has published more than 220 papers and edited 7 scientific and technical monographs.

In the international arena, he has conducted the first comprehensive and systematic research on the pulpability of more than 40 kinds of fast-growing woods such as Acacia, Eucalyptus, Poplar, Birch and Pine, providing an important theoretical basis for the development of high-yield clean pulp production technology; he has presided over the EU Fourth Framework Programme "Industrialization Technology Research on Biobleaching and Wastewater Treatment of Straw Pulp", which is one of the first projects at home and abroad to carry out biobleaching technology and promote the development of the technology. He is one of the early experts in domestic and foreign countries to carry out biological bleaching technology and promote industrialization application; cooperated with the University of Quebec in Canada on the project of "High-efficiency and low-cost treatment technology of paper wastewater", and the project team experts were awarded the Chinese Government Friendship Award by the State Council; in particular, he overcame the common problem of making high-quality pulp from mixed materials, and designed the first clean pulp production line independently, which broke the high yield pulp production technology. In particular, he overcame the common problem of making high-quality pulp from mixed materials and designed the first clean pulp production line independently, which broke the situation of complete dependence on imported high-yield pulp equipment.

He attaches great importance to the industrialization of scientific and technological achievements and their application. He has led his team to build 16 mixed material high-yield clean pulp production lines in Shandong and Fujian, and to upgrade 32 imported high-yield pulp lines, covering more than 70% of China's high-yield pulp production capacity. In the past 3 years, 18.7 million tons of pulp were made with this technology, increasing income for foresters by more than 22 billion yuan; new sales of 22.8 billion yuan, new profits of 2 billion yuan; saving 50 million cubic meters of high-quality wood, 180 million cubic meters of water, 6.96 billion kilowatt hours of electricity, and 150,000 tons of COD reduction.

Cultivate high-level talents in forestry and grass

As the national team of forestry and grass research in China, the Chinese Academy of Forestry not only undertakes major national forestry science and technology tasks, but also has the mission of training high-level talents for national forestry and grass science and technology.

Since he became the supervisor of master students in 1995 and doctoral students in 2003, Mr. Fang Guigang has trained more than 200 high-level talents for the country, including two visiting scholars of "Western Light" of the Ministry of Organization and eight Chinese dual-degree biology masters of UNESCO. Among them, there are two visiting scholars of "Western Light" of the Ministry of Organization, and eight Chinese double-degree Master of Biology of UNESCO.

He has several jobs and has heavy scientific and administrative tasks, so he has almost no rest throughout the year except for the Spring Festival when he goes home to visit his family. However, for the graduate students he supervises, he always comes to the lectures on call, follows the progress of the research, holds regular group meetings and communication meetings, summarizes and summarizes at the right time, and explains and solves the doubts in time.

In the process of teaching, he focuses on cultivating students' ability to analyze and think, ask questions and solve problems; with a forward-looking vision and a high sense of responsibility for the cause of forestry and chemistry, he devotes himself to supporting and helping students grow, and has trained a large number of excellent young and middle-aged scientific and technological backbone talents.

He always prepares his lectures carefully and incorporates the latest international research results and the latest research progress of his team into his courseware to ensure that students can relate theory to practice and keep abreast of the latest trends in the industry; at the same time, he maintains his early habit of writing on the board and, according to students' questions, draws plant cell structures and core components of equipment by hand on the blackboard to stimulate students' strong interest through a subtle and in-depth approach, which is loved by students.

As the preacher of students, Fang Guigang is also committed to the popularization of science and experience of the industry and the dissemination of knowledge. He has been invited for many times to conduct training for scientific researchers from France, Sweden and other countries in the forest industry; in cooperation with the Ministry of Commerce's foreign aid training, he has taught scientific researchers from third world countries for many years. As a member of the Steering Working Group of Light Chemical Engineering of the Steering Committee of Light Engineering in Higher Education, he has participated in the evaluation of the planning textbooks of light chemical engineering and the construction of first-class majors, golden courses and new engineering education reform projects. As the leader of domestic high yield clean pulp industrialization technology, he actively participates in academic conferences and shares cutting-edge scientific and technological achievements and industrialization transformation experience to teachers and students and domestic and foreign counterparts through invited reports and keynote presentations.

Over the years, Fang Guigang has optimized and updated the multi-step teaching and training model to support the personal development of professional postgraduates in all aspects, providing them with professional knowledge and ability reserves for their eventual scientific research positions in forestry, paper making, biochemistry, pharmaceuticals and other fields, and is known as a "guide" by students.

Committed to tackling the "neck" problem

In 2022, Fang Guigang has set a new goal for himself.

For China's forest and paper industry exists in the fiber raw materials dependence on imports, key technology and equipment dependence on imports and other "neck" problem, he will lead the team in the expansion of new paper fiber raw materials, reduce the amount of chemicals to reduce the amount of pollution, improve the proportion of chemical pulp copying to improve the physical mechanics and optical properties of paper and paperboard, key core equipment research and development He will lead the team to continue to carry out scientific and technological research in the areas of expanding new paper fiber raw materials, reducing the amount of chemicals, reducing pollution, improving the ratio of chemical pulp to improve the physical, mechanical and optical properties of paper and paperboard, and developing key core equipment.

Fang Guigang thinks, papermaking is a basic raw material industry that affects the people's livelihood, in continuing to adhere to the integration of forest and paper strategy at the same time, we should pay great attention to forestry "three leftovers", agricultural straw utilization problems.

In the use of forestry residues and agricultural straw pulp, he proposed three models: First, there are large OCC as raw materials for pulp and paper enterprises to take a high rate of chemical mechanical pulp technology route, new forestry residues, straw pulp line, used with OCC with the production of high-strength corrugated base paper and natural color packaging board, the preparation of waste made into type of granular fuel or organic compound fertilizer, etc., can be increased production without increasing pollution does not increase The second is a mixture of grass and wood cooking chemicals. Second, the grass and wood mixed cooking chemical pulping, can improve the black liquor evaporation concentration performance, in the traditional alkali recovery system to achieve smooth operation. Third, the existing chemical wood pulp enterprises to add grass raw material chemical mechanical pulp production line, supplemented by efficient removal of SS and pH control technology, the use of MVR technology to pre-process thick grass pulp black liquor, into the wood pulp black liquor alkali recovery system.

He believes that during the "14th Five-Year Plan" period, the key research directions that should be supported in the field of forest and paper integration are: key technologies and key equipment for forestry residues such as straw collection - baling storage and transportation - stock preparation, comprehensive utilization technologies for solid waste in stock preparation and pulp making process, large-scale high-density homogeneous pre-soaking technology and equipment, energy-saving high-density disk mill refining technology and equipment, and energy-efficient extraction and concentration technologies for waste liquor. The technology and equipment for efficient extraction and concentration of waste liquor, the technology and equipment for reuse of short process of middle section water treatment, and the technology for materialization of modification of high yield pulp.

He firmly believes that in the near future, forestry residues and grass pulp will make a greater contribution to alleviating the shortage of paper fiber raw materials in China, implementing the "energy saving and emission reduction" and "double carbon" strategies, improving the income of forest farmers and promoting rural revitalization.
