Purebase Corporation is in discussions with Fortera Corporation regarding the proposed terms of a commercial plant agreement. Purebase and Fortera recently entered into a non-binding term sheet and are working towards a definitive agreement that sets the terms of a collaboration to design, construct and operate a commercial facility at Purebase's headquarters in Ione, California. Fortera is the owner of know-how and intellectual property related to its ReCarb process for the production of calcium carbonate cements.
For the past six years, Purebase has been working with universities, state Departments of Transportation and a private development testing facility to develop alternative supplementary cementitious materials to be used to replace a portion of cement in the production of concrete. Historically, coal fly ash has been the most common replacement for cement, but it is primarily generated by coal-burning power plants which are also high in carbon emissions.
