Calumite International has a clear and obvious commitment to the community, the environment, and the people who are impacted by Calumite Slag.  We work tirelessly to minimize the environmental impact of glass production while creating the highest quality glass products.  And by reducing costs for glass producers we are creating more opportunities for consumers.

We have a responsibility to our environment, to this land, and to the people who call it home. From safety to quality we are all of one mind, to offer our highest and best in the pursuit of a better world.
