How it works The fuel is burned, which heats water into steam, which turns turbines, which in turn drive generators, just like in a fossil-fuel power station. The station usually provides power for the sugar mill, as well as selling electricity to the surrounding area. Advantages It makes sense to use waste materials where we can. The fuel tends to be cheap. Less demand on the Earth's resources.
Disadvantages Collecting the waste in sufficient quantities can be difficult.
We burn the fuel, so it makes greenhouse gases. Some waste materials are not available all year round. Biomass is renewable , as we're going to carry on making waste products.
