As a functional filler and reinforcing agent, carbon black accounts for more than 30% in tires. Its addition can improve tire wear resistance and anti-skid properties, reduce rolling resistance, and thus extend tire service life.
As a functional filler and reinforcing agent, carbon black accounts for more than 30% in tires. Its addition can improve tire wear resistance and anti-skid properties, reduce rolling resistance, and thus extend tire service life. However, this material derived from fossil energy has the disadvantages of high energy consumption and heavy pollution. In recent years, to enhance the environmental competitiveness of their products, tire manufacturers have been committed to improving tire rolling resistance to reduce vehicle fuel consumption. Given that the production of carbon black filler generates a large amount of greenhouse gases, many manufacturers are trying to use renewable raw materials such as lignin, rice husk, and corn starch.
Lignin is the second most abundant renewable carbon source on Earth after cellulose. Several promising application products of this renewable material that have been confirmed include resins, adhesives, binders, fillers, polymer modifiers, etc. One of the potential uses of lignin is to replace carbon black as a reinforcing filler and vulcanizing agent for rubber in tires. This renewable lignin raw material can not only reduce the demand for fossil materials and lower carbon emissions in tire manufacturing, but if it enters the global tire market in the future, it will help make significant contributions to the sustainable transformation of the entire transportation sector and even broader fields, and the energy consumption of tire manufacturing will be greatly reduced.
The Future is Here
Our integrated biomass refining project in Dulbert uses renewable raw materials such as corn cobs, reeds and other agricultural waste, as well as plant straws. Through three-element separation technology, lignocellulose particles and lignin particles in crude lignin are separated. The separated cellulose can be used to produce new-generation biochemicals such as bioethanol, pulp molding, and battery hard carbon anode materials. Lignin is treated by hydrothermal carbonization to obtain lignin derivatives with high carbon content and functional functional groups, which enable them to play a role in rubber substrates.
As a leader among various negative carbon solutions, the lignin rubber reinforcing agent RRA-DT1 officially enters the rubber and tire market as a renewable functional filler. As a new generation of renewable functional filler, RRA-DT1 is not only a brand-new material, but also represents an innovative replacement for the main functional fillers in current rubber and plastic products - fossil-based carbon black and precipitated silica. This breakthrough has achieved a major shift from fossil raw materials to renewable raw materials, demonstrating both its application value and innovative concepts in sustainable development, laying a solid foundation for the expansion of biomass refining business, and helping the sustainable transformation of transportation and other fields.
Lignin Rubber Reinforcing Agent RRA-DT1 Technical Manual
RRA-DT1 lignin rubber reinforcing agent has become the core material for rubber industry upgrading, relying on its ultra-high purity, precise particle size control, and green sustainability. Its technical parameters and performance advantages are as follows:
1. Ultra-high Purity and Chemical Stability
Using biological solvent refining technology, it achieves ultra-pure standards with impurity content <0.5% and ash content <1.2%. The unique molecular structure ensures excellent chemical compatibility with rubber matrices, effectively avoiding cross-linking side reactions caused by impurities and maintaining uniform dispersion in complex processes such as mixing and vulcanization. By strengthening the rubber network structure, it significantly improves the tensile strength (15%-20% increase), wear resistance (18% reduction in abrasion), and anti-aging performance (30% extension in anti-ozone aging time) of products.
2. Precision Particle Size Engineering Control
Based on nanoscale crushing technology, it realizes precise particle size distribution with D90 ≤15μm (supporting 5-20μm customized services). The highly uniform particle size distribution significantly enhances the dispersibility in the rubber system, optimizes the internal stress distribution of products, and improves the consistency of overall mechanical properties.
3. Full Life Cycle Green Attributes
Adopting a zero-sulfur emission biological refining process, the energy consumption during production is 40% lower and carbon emissions are reduced by 65% compared with traditional carbon black, complying with strict environmental standards such as EU REACH and US ASTM to help enterprises achieve ESG goals.
4. Excellent Cost-effectiveness
Under the same reinforcing performance, the comprehensive cost of RRA-DT1 is 12%-18% lower than that of traditional reinforcing agents. It significantly improves production efficiency and economic benefits by reducing vulcanization time, lowering mixing energy consumption, and other multiple approaches.

Biomass refinery integrated technology - Convert low-value feedstocks into high-value sustainable chemicals and degradable materials .This new technology innovatively uses new biological solvents to carry out selective physical dissolution and separation operations on biomass raw materials.
In the treasure trove of natural substances, cellulose holds a unique and crucial position. At the microscopic level, cellulose is a large-molecule polysaccharide formed by the linkage of glucose molecules. It has a "aloof" nature, being insoluble in water and not readily interacting with common organic solvents.
Hemicellulose, as a kind of biopolymer, is a mixture of highly branched low-molecular-weight homopolymers and heteropolymers. It is widely distributed in plants, accounting for about 15% - 20% in coniferous wood, and 15% - 35% in broad-leaved wood and gramineous grasses. It coexists with cellulose in the plant cell wall.
