IDENTIFICATION AND ASSESSMENT OF MOST PROMISING BIOREFINERIES UNTIL 2020 IN IEA BIOENERGY TASK 42 “BIOREFINERY”

摘要

The IEA Bioenergy Task 42 ?Biorefineries“ made the following definition on biorefinery: “Biorefiningis the sustainable processing of biomass into a spectrum of bio-based products (food, feed, chemicals, materials) andbioenergy (biofuels, power and/or heat)”. “Energy-driven” biorefineries and “product-driven” biorefineries aredistinguished. Based on the ongoing activities in the 12 countries (A, AUS, CA, DK, FR, G, I, IR, NL, T, UK, US)participating in Task 42, the task identifies and assesses the current status and development potential of both “energydriven”biorefineries (incl. biofuels) and “product-driven” biorefineries. These assessments are based on a “FullValue Chain approach”, covering raw material issues, conversion processes and final product applications in anintegrated approach. As a first step the 15 most interesting “energy-driven” biorefinery concepts until 2020 and theirvalue chains, including the integration and deployment options in existing industrial infrastructures, are analysed.These concepts produce the following transportation biofuels: biodiesel, bioethanol, FT-biofuels, biomethane fromupgraded biogas and SNG (synthetic natural gas) with the following feedstocks: oil crops, oil residues, sugar andstarch crops, wood chips, straw, grass, saw mill residues, (sulfite) liquor, algae. The Task 42 is assessing thesustainability of these concepts by analysing economic, environmental and social aspects in comparison toconventional processes and products.
