The company URSA is the first on the market to present products that use LIGNIN technology and are only available from it. Sustainable lignin technology brings a new, environmentally friendly and high-quality insulation material.

“URSA goes green” is the long-standing vision of this company and represents its commitment to greater environmental awareness, which it implements in practice throughout the entire process of production activities.
The use of innovative technology marks the beginning of a completely new era that is bringing us closer to the sustainable development of insulation materials in the construction industry.
What is lignin?
LIGNIN is a natural polymer which is found in wood and other plants. It serves as a glue that joins the cellulose fibers and, among other things, ensures the strength and stability of the wood. In addition, it is resistant to UV rays, moisture, bacteria and fungi.
It is a by-product that is created during the production of paper and pulp and turns into resin. It is a renewable raw material available in large quantities without further degradation.
Why lignin in mineral glass wool?
Mineral glass wool looks similar to sugar foam. Quartz sand and recycled glass are melted and spun into thin threads. The only difference is that the mineral glass wool fibers don’t hold together by themselves – they need a binder.
Lignin is the champion in every comparison
The URSA range of products made from mineral glass wool using lignin technology presents the most natural insulating materials available on the market.
In this way, URSA contributes to the protection of the global climate and the health of the inhabitants. In addition, the insulation products of this company significantly contribute to the reduction of energy consumption and consequently reducing CO emissions2.
Years of intensive research made it possible to replace existing fossil fuels in the production of mineral glass wool.
New groups of premium products created with the help of lignin technology represent the beginning of a new technology for sustainable insulation materials in the construction industry.
Lignin is an environmentally acceptable alternative, the use of which in the future will be constantly upgraded and expanded to the entire range of products.
Premium properties of sustainable products produced with lignin technology:
- naturally degradable;
- contribute to a high quality of life;
- healthier indoor climate;
- they are biologically based;
- sustainable technology;
- products contain a high proportion of recycled material
Due to the quality of production, the products received international certificates: Blue Angel, EUCEB, RAL i EPD.
Lignin binder from UPM Biochemicals
For the production of two products – URSA SF 32 i URSA SF 34 – Kraft lignin is used, and the basic material is a product of the company UPM Biochemicals – BIO Piva 100.
UPM is present in major industry segments, such as renewable glycol end-uses that include textiles, PET bottles, packaging, refrigerants, composites, pharmaceuticals, cosmetics and detergents.
Renewable Functional Fillers (RFF) based on lignin are a viable alternative to deposited silica in a wide range of rubber and plastic applications.
UPM Biochemicals nudi innovative, sustainable and competitive biobinders based on wood that replace fossil raw materials and improve the impact on the environment in various applications.
Biobinders based on kraft-lignin, which is a waste product of wood processing, help in the transition from fossil raw materials to a more sustainable, CO-neutral future2.
UPM is building an industrial biorefinery in Leuna, Germany, which will process solid wood into next-generation biochemicals (liquid synthetic fuels).
