Waste heat in district energy

22 April 2022

Waste heat is heat generated from some process or infrastructure often emitted to the surrounding air.  The industrial waste heat recovery potential is large but it is still largely untapped- Sweden is world champion on waste heat recovery from industry into district energy: 9% of the heat supply. There is also waste heat generated in cities by the people living and  working in them- there is a potential to meet 10% of the heat demand in EU 28 by using urban waste heat.
