CRSI: Recycled Materials
Likewise, cement often is replaced by supplemental cementitious materials that otherwise would enter the waste stream. This contribution by reinforced concrete in providing recycled materials is recognized by LEED. More than 7 million tons of scrap steel is recycled into reinforcing bars every year, virtually the entire feedstock. This recycling avoids a massive energy expenditure — one ton
