Process steam is very important in industrial production processes. This form of energy is particularly used by the chemical industry. It is becoming increasingly common for industrial companies to use energy from a waste incineration plant nearby.

Process steam generation is based on the combined heat and power generation principle. The turbine of a waste incineration plant is driven by the steam generated by combustion of waste. This only gives rise to electrical energy.

Removal of part of the steam from the turbine allows the steam to be used in different ways: to generate district heating, as process steam for industrial processes and for generation of electricity. The energetic potential of waste permits this utilisation.
