A great deal of our modern way of living literally rests on the simple use of cement. Without this useful substance we could not produce concrete, the fundamental ingredient of our houses, buildings and skyscrapers. Unfortunately, one of the costs of making cement is that it is highly damaging to the environment. To obtain the raw materials for cement requires quarrying, which has various impacts on the surrounding ecosystems. During the production process of cement, CO2 emissions come from both the heating of calcium carbonate as well as from the machines needed for production. This production process has also been found to release heavy metals such as cadmium, mercury and thallium into the atmosphere. To offset these hazardous effects, CERATECH, an Alexandria, Virginia based company, has created KEMROK – the eco-friendly cement.

KEMROK is cement that is composed of 5% renewable materials and 95% cast-off ash. This is doubly helpful because the cast-off ash would typically end up in a landfill and it also prevents the need for new raw materials to be used. By using these materials, KEMROK is virtually carbon neutral, whereas typical cement production creates one ton of CO2 for every ton of cement produced. It also does not require the decomposing of limestone, which produces CO2, nor the use of fossil fuel burning machines for heat. KEMROK should be the cement of choice for any company intent on meeting regulations for “Green” status or LEED certification.
