Biorefinery concepts

According to IEA Bioenergy Task 42, ‘biorefining’ is the sustainable processing of biomass into a spectrum of marketable bio-based products (food/feed ingredients, chemicals, materials) and bioenergy (biofuels, power and/or heat). Providing a classification of biorefineries, VDI standard 6310 distinguishes the following biorefinery concepts:

  • Sugar biorefineries
  • Starch biorefineries
  • Vegetable oil and algal lipid biorefineries
  • Lignocellulose biorefineries
  • Green biorefineries
  • Synthesis gas biorefineries

ifeu has been working on the environmental impacts of biorefineries since the 1990s and evaluated dozens of biorefinery concepts for biodiesel, bioethanol and biogas but also bio-based products. In recent years, a specific focus was put on lignocellulose biorefineries and algae biorefineries. Most often, life cycle assessment and sustainability assessment studies were performed.
