A crucial step in developing the U.S. bioindustry is to establish first-of-a-kind integrated biorefineries that are capable of efficiently converting a broad range of biomass feedstocks into commercially viable biofuels, biopower, and other bioproducts. Integrated biorefineries are similar to conventional refineries in that they produce a range of products to optimize both the use of the feedstock and production economics. Integrated biorefineries use novel technologies and diverse biomass feedstocks—requiring significant investments in research, development, and deployment to reduce costs and improve performance to achieve competitiveness with fossil fuels.

Integrated biorefineries employ various combinations of feedstock and conversion technologies to produce a variety of products, with the main focus on producing biofuels. Co-products can include chemicals (or other materials), animal feed, and heat and power. The renewable feedstocks utilized in integrated biorefineries include non-food sources, including the following:

  • Energy crops, such as switchgrass, miscanthus, willow, and poplar
  • Agricultural, forest, and industrial residues, such as bagasse, stover, straws, forest thinnings, sawdust and paper mill waste
  • Algae and other micro-organisms.

Federal support for first-of-a-kind integrated biorefineries can help validate costs and performance, thus reducing the technical and financial risks associated with new technology deployment. Reduced risks will allow access to private financing, which is necessary to accelerate growth in the U.S. bioindustry. This work supports the national "all-of-the-above" strategy to develop every source of American energy—reducing costs to consumers and improving energy security.
