Fu-Tung Cheng explains that concrete's inherent durability goes hand in hand with "timeless design", sustainability, and, of course, functionality. Aesthetic design also must be well thought out if you don't want it to become outdated. Cheng Design Products Inc. in Berkley, CAis the birthplace of his timeless designs for countertops.
Sustainability in concrete includes using "recycled waste materials and using nontoxic water based finish."-Concrete Network
At Concrete Zen we "reduce the ecological footprint" by using VCAS which is locally supplied. Recycled glasscan also be used in the mix depending on the style of countertop. Our non-reactive stains are water based or soy based.--Elizabeth E.
