How can we make sectors working at very high temperature, such as foundries and metal processing industries, more energy efficient?

There are significant opportunities for energy conservation, energy savings and energy efficiency in high-temperature industries such as foundries and metal processing industries, whose processes involve temperatures upwards of 300 degrees C. These, however, could require solutions that are customized to their operations and processes. What are the technologies, innovations and tools through which these sectors could reach much higher levels of energy efficiency?
