Renewable energy from residual waste

What’s happening? How does it happen?

BIOSTOOM Ostend produces green electricity from residual waste originating from pre-treated commercial waste or household waste. Steam is produced with the heat that is released during the combustion process and it is producing electricity by driving the turbines. The bottom ash is completely valorized as a secondary raw material.

The energy production throughout the steam turbine is powered by pre-treated commercial waste and household waste. It is relevant to highlight the circularity of this initiatives, since the bottom ashes coming from the combustion of the waste are reused as secondary raw material, and since the steam is re-transformed again in water and reused in the process in order to produce energy.
