  1. Making Biorefineries Competitive: PRO.E.SATM The only sugar platform available today Guido Ghisolfi June 8, 2012

  2. Three points that will change the industry: • Commercial-scalecellulosic ethanol plant, Q3 2012: 20 million gallons, Crescentino (13 to start) • Cellulosic costs less • No subsidies required

  3. M&G Group: Biomass Technology & Experience Engineering Division $3B per year #2 producer of PET Technology for biomass to sugars

  4. PRO.E.SATM Technology Step by Step • 2006 – 2008 • Scouting of technologies; • Generation of key inventions; • Proof of UNIT OPERATION in the labs. • 2009 – 2010 • Pilot plant construction & start up (June 2009); • Pilot plant operation and data gathering; • Test of plant flexibility using multiple biomasses. • 2011 – 2012 • Crescentino unit; • Technology licensing.

  5. PRO.E.SATM Technology YEAST BIOMASS C6 Sugar PRO.E.SATM Technology Separation Fermentation ETHANOL C5 Sugar LIGNIN ( Energy Generation) Ready solution for industrial production of 2G Ethanol A Total Project Solution based on: Agronomy: Field experimentation and best energy crops identified and characterized; Biomass Pre-Treatment and Viscosity Reduction: Continuous process developed and piloted to produce cost-effective and clean fermentable sugars; Hydrolysis and Fermentation: Unique hybrid SSCF process scheme yielding high ethanol concentrations.

  6. Crescentino Plant

  7. PRO.E.SATM Technology: From Biomass to Sugar • Without use of chemicals; • Optimizing C5 and C6 sugar extraction; • Minimizing the formation of by-products/inhibitors; • Using continuous equipment enabling design for large scale plant; • Minimizing CAPEX and OPEX.

  8. The Continuous Pilot Plant: How it operates… • Biomass agnostic; • No biomass drying / grinding required; • Low level of inhibitor (lower then in P.O.C.); • No use of chemicals (only steam is added); • Reduced enzyme loads; • Rapid liquefaction of the solid material; • High solid concentration (>40%) in the hydrolysis step.

  9. Biomass: Our Experience at Pilot Plant • PRO.E.SATMtechnology is flexible in feedstock supply: possibility to treat worldwide crops; • Several biomasses were evaluated and tested as potential feedstock for the PRO.E.SATM technology: Internal analysis according to Chemtex methods

  10. Pre-Treatment Section: Biomass Type High feedstock flexibility • Energy crops: • Arundodonax (giant reed); • Miscanthusgiganteus; • Panicumvirgatum (switchgrass). • Agricultural and industrial residues: • Wheat straw; • Rice straw; • Sugarcane bagasse. • Woody species: • Eucalyptus; • Poplar, Internal data tests at pilot scale • Differences in yield (4 to 5 tons dry biomass/tons EtOH) index mainly depends on feedstock composition; • It is possible to reduce the yield variability optimizing the process condition.

  11. Hydrolysis and Fermentation High solid concentration enzymatic hydrolysis is needed to guarantee the economics of ethanol recovery through distillation M&G solution Available solution

  12. LCA – Full Scale Projection • The lifecycle performances of bioethanol produced through Chemtex technology at a full industrial scale have also been estimated by means of the GREET model; • Scale benefits will allow a further improvement of the bioethanol environmental profile. - 84% - 91%

  13. Baseline Process Scheme 2G Bioethanol Plant TECHNOLOGY IS READY! Biomass 2G BIOETHANOL THOSE INTERMEDIATES REPRESENT A STARTING POINT FOR A NEW GREEN CHEMISTRY BASED ON RENEWBLES

  14. How to exploit PRO.E.SATM Technology ENZYMES ETHANOLOGEN …? …? …? • We can adapt the composition of the sugar stream to various fermentations: • With / without lignin; • Higher / lower sugar concentration; • Free from inhibitory compounds.

  15. How to exploit PRO.E.SATM Technology JET FUEL ETHANOL BUTANOL GREEN DIESEL 1,4 BDO ACETIC ACID EG ADIPIC ACID PE PX FATTY ALCOHOLS THE BIOMASS SUGAR PLATFORM
