Engineering Company



KEMA is an international engineering company operating within energy and environment related fields (thermal and nuclear plants, waste incineration…). An increasing part of its activity is focused on unconventional solutions such as co-combustion of wood and coal and wood gasification, which put less strain on the environment.



Wood-fuel expertise


- Analyses of wood waste.

- Spontaneous combustion.

- Monitoring of combustion (fuel, gas emissions, ashes…).

- Supervision of pilot operations (1 MW).

- Generalisation to operations on a wider scale.



Region of operation and fields of application


. All countries.


- Co-combustion of wood mixed with pulverised coal.

- Re-use of ashes.

- Wood gasification and high efficiency wood power plants.
