Our Story

Big Blue Technologies (BBT) LLC is a privately-owned company based in Denver-Boulder greater area of Colorado and was established in May 2015. BBT is a spin-off from the University of Colorado at Boulder’s Technology Transfer Office, with an option agreement on licensing patents, trademarks, and trade secrets that are formalized under ARPA-E award number DE-AR0000404. BBT and CU-Boulder have examined the prior art on carbothermal reduction for producing magnesium and have determined the fundamental reasons for past failure. CU-Boulder has filed patent applications with a new understanding of this chemistry with underlying importance given to the method of condensation and recovery at high yields. This is the key to improved process efficiency and reduced production costs. The carbothermic route to commercial-scale magnesium production has been revived.
