One of the unintended “products” of intensive energy using production processes is excess heat, also called waste heat. Excess heat can for instance be found in the chemical, cement, iron and steel making, and the pulp and paper industry. The constantly growing demand for energy and resulting climate change effects are reinforcing interest in the application of excess heat, while increasing knowledge about industrial symbiosis makes facilitation easier. The growing costs of energy and the big loss of waste heat is the basis for the fact that recovering of waste heat is the most promising and cost effective option to reduce the world-wide amount of industrial energy consumption (International Energy Agency 2010). Waste recovery and reuse also provide financial savings, reduction of CO2 and NOx, and innovation by quality improvement of processes and products. Besides the single company’s internal improvement of excess heat recovery, the concept of industrial symbiosis provides a basis for waste heat exchange between companies as examples in the Netherlands and Sweden illustrate.
