With the issues of environmental pollution and resource crisis have been captured more and more attentions, natural polymer with renewable, biodegradable properties receives increasing attention, the use of waste and renewable resources has become one of key subjects in the world. In nature, lignin is one of major renewable resources, its reserve second only to cellulose, and regenerates with the speed of 50 billions tonnes per year.
Though China is one of major lignin products manufacturers in the world, the research of lignin products is still at early stage. Three kinds of raw materials can be used to produce lignin In China, namely black liquor of papermaking, grain straw and by-products of cellulose fuel ethanol production, using black liquor of papermaking and grain straw as raw materials to produce lignin has been commercialized in China. At present, lignosulfonates are the main lignin-based product in China, with the output of over 400,000 tonne in 2009.
In this report, CCM International researches lignin industry in light of raw materials, technological development, application situation, etc. through study the entire industrial chain of lignin. To explore the above key aspects, you can find the answers to the following questions:
Information in the report can help readers grasp general production, application situation and R&D progress of lignin products in China, and can provide reference for readers' investment decision as well.
In China, three kinds of raw materials can be used to produce lignin, namely black liquor of papermaking, grain straw and by-products of cellulose fuel ethanol production. At present, most lignin manufacturers mainly adopt black liquor of paper making as raw material to produce lignin in China.
In recent years, black liquor supply has been gradually reducing because more and more non-wood pulp manufacturers have withdrawn from paper industry under stricter implementation of national environmental protection policy.
There are two kinds of technologies namely chemical method and enzymolysis method that can directly use grain straw as raw material to produce lignin.
Production cost is much higher by adopting chemical method than enzymolysis method to produce lignin, as only lignin components of grain straw can be utilized by chemistry method, while all the components of corn straw including hemicellulose, cellulose and lignin can be completely utilized, which can bring much profit to manufacturers.
The research on extracting lignin from by-products of cellulosic ethanol is at initial stage currently.
In this report, lignin indicates lignosulfonates, alkali lignin and high-purity lignin.
Currently, China is an important lignosulfonates production country in the world with total output of ** tonnes in 2010 (Jan.-Nov.). Currently, domestic production of some lignosulfonates still stays in experimental stage because of its immature production technology.
In recent years, consumption of lignosulfonates in architecture industry and ceramic industry saw uptrend, thanks to rapid development of real estate industry in China. In China, the demand for lignosulfonates will grow fast by about **% annually in the next several years, thanks to the increasing domestic demand from architecture industry and ceramic industry.
Output of alkali lignin has reached from **tonnes in 2006 to ** tonnes in 2010 est., with CAGR of **%. By Dec. 2010, there are nine active alkali lignin manufacturers in China, with total capacity of ** tonnes.
Currently, the market size of alkali lignin by output and sales value is smaller, compared with that of lignosulfonates in 2010. In 2010(Jan.-Nov.), consumption volume of alkali lignin is ** tonnes in China. Meanwhile, consumption of alkali lignin in architecture industry and coal slurry industry have reached ** tonnes and ** tonnes respectively, accounting for **% and **% of total alkali lignin consumption in China.
In 2010 est., the capacity and output of high-purity lignin have reached 42,000 tonnes and ** tonnes respectively. By Dec. 2010, there are only 2 active high-purity lignin manufacturers in China, with total capacity of ** tonnes.
High-purity lignin is mainly sold in domestic market, with consumption volume estimated to be about ** tonnes in 2010 est. In 2010 est. about ** tonnes of high-purity lignin are consumed in phenol formaldehyde resin, accounting for **% of total consumption.
There is only one active producer namely Changzhou Shanfeng manufacturing lignin polyether polyols with total capacity of **t/a in 2010. Its total output of lignin polyether polyols during January to November of 2010 in China is about ** tonnes.
As an emerging product, the consumption volume of lignin polyether polyols is very small with total consumption volume of only ** tonnes in China from January to November 2010. Among that, ** tonnes of lignin polyether polyols is consumed to produce rigid polyurethane foam during this period.
Currently, there is one main producer of lignin phenol formaldehyde resin in China, namely Changzhou Shanfeng. Jilin Laihe is a potential producer, who is estimated to formally enter lignin phenol formaldehyde resin industry at the end of December 2010.
Lignin phenol formaldehyde resin has become a substitute of oil-based phenol formaldehyde resin and is largely used in man-made board, various wood products, nylon, fiber reinforced plastics and foam plastic as adhesive. Besides, lignin phenol formaldehyde resin is also used in high temperature areas such as refractory material, friction material and casting industries as adhesive.
The technology of using the mixture of lignin and carbon black as raw material to produce reinforcing agent of rubber products will have good prospect in the future, mainly because of the lower production cost compared with that by using only carbon black as raw material to produce reinforcing agent, as lignin price is much lower than that of carbon black. But this technology won' t be commercialized in the future three years, because the research about this technology hasn' t achieved a large progress and few applications for patents about this technology have been approved currently.
