Kitchen Countertops / September 10, 2018 / Anthony Williams
Sustainability: The cement in concrete is derived from heating limestone, which is a carbon-intensive process that creates gas emissions. However, slag cement, fly ash and silica fume — all industrial waste by-products that are carbon neutral — can replace more than 50 percent of the cement, reducing emissions and improving the concrete’s ecofriendliness.
The basics: Recycled paper countertops are composed of postconsumer wastepaper, nonpetroleum-based resins and pigments. This mix is heated and compressed into a dense, monolithic slab with a feel that’s often compared to a warm, soft stone — like soapstone. The primary manufacturers, PaperStone, Richlite, ShetkaStone and Kliptech, all offer several colors, though the material typically is available only in medium to dark hues, all in a smart-looking matte finish.
