Biogas production from lignocellulosic biomass from agriculture subproducts (straw, prunings) and forestry
residues was investigated, comparing methane efficiencies of these raw materials with the “traditional” biomass.
Straw has interesting methane yield potential and lower pretreatment costs compared to the other lignocellulosic
biomass. A techno-economic analysis of a 1 MW existing plant in two typical biomass supply configurations has
been evaluated, comparing with other configurations using lignocellulosic biomass. Although the higher supply
costs (+40%) for the proposed application due to the operative costs for steam explosion and the investment costs
for pretreatment, there are important environmental advantages: the reduction of the land usage (50%) leads to a
