Industrial waste produced in the UAE, valuable high-temperature materials for thermal energy storage applications

Several industrial waste from metal industries in the UAE have been identified to be recycled as low-cost materials for high-temperature thermal energy storage (TES) systems development. Electric arc furnace (EAF) slag, ladle furnace (LF) slag, aluminum pot skimming (APS) and aluminum white dross (AWD) have been chemically and thermally characterized. Chemical analysis showed that these materials contain relatively inert components and are non-hazardous in general (neglected amount of heavy metals). In addition, except for APS, these wastes were in general stable at high temperatures up to 1100 degrees C after performing one or two thermal cycles. (C) 2015 The Authors. Published by Elsevier Ltd.
