According to Peter Bakker, President and CEO of the World Business Council for Sustainable Development “Cement production accounts for approximately 5% of worldwide man-made CO2 emissions” (World Business Council for Sustainable Development). This high output of greenhouse gasses is largely due to the energy required to mine and process the raw materials into a marketable product. Traditional Portland cement also uses as much as 6 gallons of water per bag, or 36 gallons per cubic yard, requiring nearly as much water by weight as the concrete mix itself (Portland Cement Association).  

As concrete is an essential building material, we cannot curb emissions by reducing production. In recent years many companies have begun researching greener alternatives to traditional concrete manufacture. Fly ash, recycled glass, and other additives have begun to appear in the market to replace some or all of the traditional limestone clinker. However, in many cases, as with the usage of fly ash, carbon emissions are still deeply baked into the manufacturing process.

The manufacturing and application of our products seeks to break the dependence on mined resources, by providing a green alternative to concrete that is made largely (up to 85%) from recycled materials, using a three-part mixture consisting of recycled crumb rubber, colored glass, and a bio-based or epoxy binder designed specifically for maximum performance for each product application.
