A clear indication of what may be considered biomass is given in the 2009/28/CE European Directive which defines it as “the biodegradable fraction of products, waste and residues from biological origin from agriculture, forestry and related industries including fisheries and aquaculture, as well as the biodegradable fraction of industrial and municipal waste”. Therefore, biomass is raw material that presents unique benefits on the market: it is available in large quantities, it respects the environment, it does not require polluting production processes and supply costs are much more contained with respect to fossil fuel.
