This article looks at six products that are either eco-friendly or fashionable. One is the Watershed Block, a brick that is made using "fused soil and rock fragments" and contains only half the cement used in making a regular concrete block. Another product, the Monarch Cored Brick by CalStar, contains no Portland cement, is made from up to 37% recycled material, and emits only "15% the carbon dioxide of traditional concrete block production," according to CalStar.
