Green Countertops: Low Carbon Concrete

Concrete is often considered a paradox to green builders. It is considered extremely sustainable (fBeachstone Katahdin Vanity Counteror example it is able to be reused, and can last significantly longer than other materials), yet 1 out of every 20 tons of carbon dioxide comes directly from cement factories. All over the world, experiments are being done to try to create a low carbon concrete. Fly ash is often used in the US as a greener alternative in limestone-based portland cement, however with decreased coal production, there will be a decrease in the amount of available fly ash.

There may be other options though. Beachstone Sustainable Surfaces is a company located in Maine that focuses on making vanity tops and tile shower accessories using 100% post-consumer recycled glass aggregate. Their product is no-VOC and the concrete binder used in it also is recycled. The company is working to develop a calcium free white cement with 40% fewer greenhouse gas emissions to decrease the environmental impact of their counter-tops. Read more here.
