Danisco developed an alternative and innovative process for making Xylitol, a low-calorie sweetener. Danisco simplified the process of creating Xylitol by utilizing a waste stream already in hydrolyzed form and therefore not needing to be broken down by acid hydrolysis, which is required in the corn cob based products utilized by many of their competitors. Danisco also co-located their production process with pulp and paper plants that already produced this hydrolyzed black liquor side stream used to produce Xylitol further reducing their impacts. Even better, the left overs of the side stream after the xylitol is extracted are fed back into the pulp and paper plant and used as a heat source for the pulp cooking, creating a circular life-cycle for the once waste product.
The use of LCA not only helped Danisco to evaluate their impacts in regard to this process, showing that they are nearly a magnitude better than the alternative process, but also provided them with credible claims now readily used by their sales and marketing departments to differentiate them in the marketplace .
