REDUCE THE CARBON FOOTPRINT OF YOUR GYPSUM BOARDS BY REPLACING PNS
Replacing fossil-based PNS fluidisers with Borregaard's bio-based Ultrazine CAF can significantly reduce the product carbon footprint of gypsum boards.1
A comparison based on publicly available Environmental Product Declarations (EPDs), including Borregaard's third-party verified EPD developed by NORSUS, shows that replacing conventional Poly Naphthalene Sulfonates (PNS)2 with Ultrazine CAF can reduce CO₂ emissions by up to 1.08 kg CO₂e per kg of product used (cradle-to-gate).
When transportation impacts are also considered, the total CO₂ savings may be even higher.
EPD-BASED Carbon footprint comparison: Ultrazine CAF vs. Industry Standard PNS
*GWP total (Global Warming Potential). Cradle-to-gate (A1-A3). 1:1 replacement.
Ultrazine is derived from wood, a renewable raw material that absorbs CO₂ during growth. As reflected in the EPD, the biogenic carbon stored in the raw material can exceed the greenhouse gas emissions generated during the production stage (A1-A3), resulting in a negative cradle-to-gate carbon footprint.
1 Lower product Global Warming Potential (GWP) can help manufacturers meet sustainability targets and reduce the embodied carbon of their gypsum boards. This is becoming increasingly important as Environmental Product Declarations (EPDs), the Energy Performance of Buildings Directive (EPBD), the revised Construction Products Regulation (CPR) (EU) 2024/3110, and future Digital Product Passport (DPP) requirements place greater focus on the environmental performance and carbon footprint of construction products.

Calculate your carbon footprint reduction
Use the calculator below to estimate the potential reduction in product carbon footprint when replacing PNS with Borregaard's Ultrazine CAF
Results are based on a 1:1 substitution ratio and publicly available EPD data. CO₂ savings are calculated using cradle-to-gate carbon footprint (A1-A3), and assume a saving of approximately 1.08 kg CO2 eq. per kg of product replaced when using a 40% solution. Actual savings may vary depending on product formulation and concentration.
