Miajadas Biomass Plant

A 15 MW plant that can operate with different types of biomass

In service since 2010, the Miajadas biomass plant was the first in Europe equipped to use two types of raw material (herbaceous and ligneous waste), which means that the supply of fuel can be diversified. It was developed as an R&D project together with companies and technology centers in Spain, Finland and Denmark, with backing from the European Union’s 7th Framework Program for support to research.
