Not that I will ever receive an answer, but I sent the information to Jim & John at J3 for their take on whether EMHI is making a play for the Cement market now, or if this is part of the (new?) plan.
GTGP only has a Joint Venture Agreement with Solucorp for the MBS cement plant market, as stated by GTGP itself. There is no exclusivity to it.
Regarding developing the market for MBS use in cement plants, GTGP has done nothing in this area as witnessed by the ZERO revenues with ZERO contracts that GTGP has had.
