The Basque Country's industrial waste heat could be reusable
Many traditional industrial processes generate heat that is normally released into the atmosphere but that could be reused. In production processes such as smelting, iron and steel, paper or cement, between 35 and 50 percent of the heat generated is lost. The efficient reuse of this industrial waste heat or its recovery for use in other processes displays a significant potential for increasing energy efficiency in industry. However, in order to design strategies for exploiting this potential, data on the quantity and flow characteristics of this industrial waste heat needs to be available. This information is not always easy to obtain and many companies do not even have a systematic record of the energy flows present in their production processes.
