Sustainability of the Biofuels and Biorefinery
Claudinei Andreoli
PRIMER FORO IBEROAMERICANO DE CIENCIAS PARA LA ENERGÍA
11 – 13 June 2012 Quito, Ecuador
The Concept of Biorefinery
Ø The concept is analogous to the concept of oil refineries: they are plants or industries or fabrics that convert biomass (feedstocks) into others products:
Energy – Foods – Fibers PlasTcs -‐ Chemicals – Enzymes
PharmaceuTcals
Current energy supply and use are unsustainable –
economically, environmentally and socially. ExecuTve Director, IEA

Types of Biofuels
Ø ConvenTonal biofuel tech (first-‐generaTon) • Sugar and starch-‐based ethanol • Oil crop based and fats biodiesel • Biogas thru anaerobic digesTon
Ø Typical feedstocks: • Sugarcane and sugar beets • Corn and wheat • Oil crops – canola, soybean, oil pam and animal fats
Ø Advanced biofuel tech (second-‐ or third-‐generaTon) • HVO (Hydrated vegetable oil) • Lignocellulosic biomass (celullosic ethanol) • Biomass-‐to-‐liquids (BtL)-‐diesel • Bio-‐syntheTc gas (bio-‐SG) • Novel tech – algae-‐based biofuels and sugar into diesel-‐type biofuels

Ø Roadmap Purpose of the Biorefinery
q IEA analysis presented in ETP 2010 and its BLUE Map Scenario,
shows that, inter alia, to stabilize atmospheric greenhouse
gases around 450 parts per million (ppm) to limit global
temperature rise to below 2°C, a significant increase in use of
low-‐carbon biofuels will be required by 2050.
q AviaTon jet fuel – 50% replacement of fossil fuel for
sustainable biofuels and 50% reducTon in GHG by 2050.
