Carbon Science Solutions LLC (CSS) is a startup that transforms distillation waste (or "stillage") into a naturally derived concrete admixture in order to improve the workability of fresh concrete and to modify the properties of the hardened mortar and concrete.
We have partnered with the Center for Applied Energy Research (CAER) at the University of Kentucky (UKY) focusing particularly on these efforts as they relate to the production of bourbon and rye whiskeys, given their importance in the state's economy.
CSS has an option agreement for an exclusive license with UKY that covers two pending patents relating to the usage of stillage as described above. Stillage is readily available (likely for little or no charge) from distilleries. In Kentucky, for example, the cost of disposing of stillage by traditional methods has increased dramatically. The cost of alternative methods of disposal or use of the waste are also expensive, prohibitively so in many cases, and, in some cases, environmentally harmful.
The use of stillage liquid as an admixture has high impact potential on both the bourbon industry and the ready-mix concrete industry. This is accomplished by not only providing a solution for a growing concern about waste disposal from the bourbon industry but also providing a highly unique and "green" no-chemical approach to concrete admixtures.
Our data, which has been supported by testing data from two international concrete producers, demonstrates that using bourbon stillage liquids in a cementitious system as an admixture increases strength, improves rheology, reduces water use by up to 35% and lowers cement CO2 footprint by up to 30%.
We are working with a ready mix concrete producer to complete a full scale field demonstration.
