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.
