Lignin Based

Deep within the cell walls of every plant, there is a powerful substance, which provides the second largest source of renewable carbon on Earth. As a renewable material, we believe that lignin will eventually replace fossil materials and completely transform the way we use natural resources to produce products.

What is lignin?

Lignin is a complex plant-derived polymer that exists in the cell walls of almost all terrestrial plants. Plants are composed of 20-30% lignin, where it acts as a natural and robust adhesive. It binds cellulose and hemicellulose together, giving wood its hardness and resistance to decay. After cellulose, it is the largest source of renewable carbon in the world.

This powerful substance found in nature is a very complex raw material. As the saying goes, "You can make anything with lignin, but you can't make money from it." In the past few decades, this situation has been changing. With the development of biomass refining technology, lignin can be extracted and transformed, thus creating new and efficient applications. It will change the sustainability performance of your products and help you fundamentally improve your carbon dioxide footprint.

Applications of lignin

Lignin has many uses in various industries, including rubber tires, carbon black, construction, dyes, plastics, and pharmaceuticals. Refined lignin can replace the fossil-based phenolic substances used in resins, such as in plywood, oriented strand board (OSB), laminated veneer lumber (LVL), medium-density fiberboard (MDF), paper lamination, and insulation materials. Other potential uses include carbon fibers and carbon storage energy, etc.

Application fields of lignin

Lignin is widely used in various industries. The applications of lignin and its modified products mainly include the following aspects:

● Construction and roads

● Carbon black and rubber

● Petrochemicals

● Textiles and dyes

● Pesticides and fertilizers

● Animal feed

● Cosmetics and pharmaceutical intermediates

● Hard carbon for battery anodes

● Can be used to produce lignin-based phenolic resin (LPF)

Sunaswan is currently dealing with lignin in different forms: free-flowing brown powder (dry lignin), wet powder (wet lignin), and liquid lignin (with a concentration of 40%-60%). The cooperative base in Dorbod is experimenting with a low-sulfur lignin, which can be used in refractories and soil conditioners.

End use and Main Advantages

Through the integrated biomass refining technology, renewable materials such as agricultural crops and plant straws are used as raw materials. Non-forestry plants such as bamboo, shrubs, reeds, and even weeds are also applicable. There is no need for any additional tree felling, and no waste will be generated. It can replace fossil-based materials in different industries and applications.

Sunawan Replaces Fossil-based Raw Materials with SQ Series Products

The world is shifting from fossil materials to more sustainable solutions. Legislators, companies, and consumers are all looking for more environmentally friendly alternatives. But can all current fossil-based solutions be replaced? Yes, we believe they can, and one solution is the SQ series of products.

SQ Series is made from lignin, which is one of the main components of plants and agricultural crop straws. It is renewable and bio-based, and can serve as a responsible alternative to many fossil-based materials.

Today, SQ Series is used in a variety of applications, from replacing phenol in plywood resins to developing bio-based and biodegradable polymers. It is even used to replace a portion of the oil-based binders in asphalt.

By using nature's own natural adhesive, our customers can create new products that are more sustainable, have a lower carbon footprint, and reduce their dependence on fossil materials.

Excellent Material Quality

SQ Series is a high-purity kraft lignin material with excellent dispersibility and a long shelf life. In order to reduce the environmental pollution caused by the spray drying process, the liquid lignin we launched provides customers with a more effective delivery method and solution. Liquid lignin can be packaged in bulk barrels, tank trucks, and liquid bags. Overall, the packaging and transportation of lignin will now be easier and faster, and our customers do not need any additional equipment. For example, ten years before we introduced liquid lignin to the market, in China, which is the largest producer and market of carbon black in the world, carbon black production companies had been using powdered lignin as a granulation adhesive dispersant. Our liquid product has saved labor and working hours for their workers. There is no longer any dust in the workshop, nor are there any torn packaging materials scattered around. Just this one point has reduced the production cost for our customers.

Purchase Lignin from a Sustainable Development Leader

SQ Series is an ideal choice for companies looking for sustainable alternatives to fossil products. There is no need for any additional tree felling to produce lignin. Our products are 100% sourced from renewable agricultural crops and plant straws. These biomass raw materials from nature are inexhaustible. With the support of advanced biomass refining technology and the three-element separation process, lignin products can be obtained that are comparable to those using traditional trees as raw materials, and are even better in some aspects. The discovery, utilization, and development of new technologies have re-endowed agricultural waste with value, while preserving forest resources.
