The market size of lignosulfonate continues to expand, and my country’s research has made new progress

Lignosulfonate, also known as sulfonated lignin, is a by-product of sulfite papermaking wood pulp. Lignosulfonate appears as a yellow-brown solid powder or viscous slurry, contains aromatic odor, is easily soluble in water, and is insoluble in organic solvents. Lignosulfonate has the advantages of good diffusibility, low production cost, and wide source of raw materials. It is widely used in water treatment, oil mining, dyes, pesticides, synthetic rubber, electroplating industry, construction engineering and other fields.

In recent years, many enterprises and scientific research institutions in my country have continued to increase their investment in the research of lignosulfonates and have made many new progresses. In 2021, the research team of Liu Weifeng of South China University of Technology used lignin sulfonate to modify polyvinyl alcohol and successfully prepared a fully degraded lignin-modified polyvinyl alcohol composite material. The strength and toughness of this material have exceeded that of general engineering plastics. It is expected that in the future, with in-depth research and technological advancement, the application scope of lignosulfonate will be further expanded.

Lignosulfonate has a wide range of applications, including water treatment, oil mining, dyes, pesticides, synthetic rubber, electroplating industry, construction engineering, etc. In the field of water treatment, lignosulfonate has the advantages of strong adsorption capacity and good flocculation and sedimentation effect, and can be used for industrial wastewater treatment such as papermaking, electroplating, printing and dyeing; in the field of construction engineering, lignosulfonate can improve the fluidity of concrete. , avoid concrete cracking, reduce concrete hydration heat, etc., and can be used as concrete water-reducing agent.

According to the “2023-2028 China Lignosulfonate Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center It shows that, benefiting from the increasingly strong market demand, the development speed of the lignosulfonate industry is accelerating. In the global market, the global lignosulfonate market size will reach US$930 million in 2022, a year-on-year growth of 5.1%. In the local market, my country’s lignosulfonate is mainly used in the field of construction engineering. As urban infrastructure construction continues to accelerate, the demand for concrete applications continues to grow, which provides broad space for the development of my country’s lignosulfonate industry.

In terms of market competition, Canada’s Tembec is the world’s largest lignosulfonate manufacturer. The competitive landscape of my country’s lignosulfonate market is relatively fragmented and the industry concentration is low. Wuhan Huadong Chemical Co., Ltd., Tianjin Shengfujiang Chemical Sales Co., Ltd., and Wuhan Fengyao Tonghui Chemical Products Co., Ltd. are major players in my country’s lignosulfonate market.

Industry analysts said that lignosulfonate has the advantages of good diffusibility and low production cost, and is widely used in many fields. With the increasing research enthusiasm of Chinese enterprises and scientific research institutions, the application scope of lignosulfonate is expected to be further expanded. It is expected that in the future, as the level of technological innovation of local enterprises continues to improve, competition in my country’s lignosulfonate market will become increasingly fierce.
