Cement, steel collaboration scales zero-emissions clinker production

Cambridge University researchers have conducted the first scrap-metal trial melt in the Materials Processing Institute (MPI) Cement 2 Zero project, aiming to prove the potential of cement clinker production using graded, recycled concrete material as flux in electric arc furnace (EAF) steel milling. The project entails a collaboration of MPI and Cambridge; construction materials producers CELSA Steel UK, Day Aggregates…

Steelmakers’ carbon emissions study template suits cement counterparts

By Don Marsh A new study, “SMA/CRU Emissions Analysis,” concludes that the output of Steel Manufacturers Association (SMA) members—electric arc furnace (EAF) operators in the U.S.—has a carbon intensity approximately 75 percent lower than that of peers running traditional blast furnaces. The EAF process underpins nearly 100 percent of concrete reinforcing steel and 70 percent of overall tonnage milled in…
