US: CR Minerals has signed a contract with mining company Rio Tinto for the supply of mineral waste from the latter's subsidiary US Borax's boron mining operations in California. CR Minerals will use the waste to produce pozzolans to replace cement in local concrete production.

CR Minerals president Jeffrey Whidden said "We have been working with Rio Tinto for several years now to bring this concept to life. Taking what was once considered waste streams and turning them into usable products for the construction materials industry is part of the vision of our company."
