XIVIA® is produced according to the DuPont Wood Based (DWB) concept, which is unique to DuPont. Its production is an example of the circular economy: XIVIA® uses a by-product of the pulp and paper industry that is, itself, derived from sustainable forestry.
A recent update of a third-party reviewed Life Cycle Assessment (LCA) confirms that XIVIA®’s carbon, water, and land use footprint is 80% to 93% lower than conventional xylitol.
Overall, the environmentally superior performance of the DWB integration concept isn’t only due to the use of the wood-based side stream as feedstock. The DWB concept is simply more efficient—and the circular economy model means a considerably lower use of chemicals and energy in comparison with corncob-based xylitol.
By replacing corncob-based xylitol with wood-based XIVIA® xylitol, the carbon footprint of a chewing gum containing 25% xylitol can be halved.
The United Nations Sustainable Development Goals address the global challenges we face and are the blueprint to achieve a better and more sustainable future. XIVIA® supports at least four of these goals:
