Bio-based solutions for construction

Borregaard is the world-leading producer of bio-based lignin-based biopolymers and cellulose fibrils for use in concrete, gypsum board and mortars.

Our lignosulfonates and cellulose fibrils product Exilva® are bio-based alternatives to synthetic polymers and can contribute to improved resource efficiency in construction applications. 

Derived from sustainably managed forests, our construction products offer a beneficial carbon dioxide (CO₂) balance. Every kilogram of additive used withdraws CO₂ from the atmosphere due to photosynthesis. As an example, when used in concrete our lignosulfonates capture more CO₂ than what is required for their manufacture. Additional CO₂ reductions are achieved from water and cement reduction in the concrete mix design while maintaining the required concrete performance. 

Environmental Product Declaration (EPD)

We offer independently verified Environmental Product Declarations (EPDs) for our liquid and powder lignosulfonates from our different sites around the world. Learn more about Borregaard's approach to EPDs here.

United Nations' Sustainability Development Goals

Borregaard’s biopolymers for construction support the United Nations’ Sustainable Development Goals number 9, 11 and 12 by improving resource efficiency (lower CO₂ emissions, less water and cement usage). This, in turn, contributes to more sustainable building.
