Benchmarking study of demolition wastes with different waste materials as sensible thermal energy storage

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.

Automated summary

Waste materials, such as demolition wastes from urban regenerations in Turkey, have shown promising potential as sustainable and durable sensible thermal energy storage materials. The study compared the storage performance of demolition wastes with other waste and by-product storage materials, revealing that demolition wastes can be used effectively for high temperature thermal energy storage applications.
