Waste materials have a great potential as sustainable and cheap sensible thermal energy storage material (STESM). There are a number of previous studies on the use of wastes as STESM such as Cofalit, coal fly ash and electric arc furnace slags, by-products of the ilmenite mining industry and by-products of the potash production, municipal waste glass and by-products generated in steel industry. The aim of this study is to assess demolition wastes (DW) from urban regenerations in Turkey as a STESM and compare relevant properties with other waste and by-product storage materials. Results show that DW developed here has better or similar storage perfor-mance compared to other STESM from wastes. DW is found to be durable up to 750 degrees C and can be used for high temperature thermal energy storage applications in packed beds.
