  1. LIG2G Seminar Reims, 2007 November 26th Lignocellulose : the biomass feedstock for today and tomorrow Ghislain Gosse [Inra]

  2. Two challenges : How to reduce greenhouse gas emissions and How to propose solutions to carbon fossil utilisation? One consequence : How to produce a huge amount of renewable carbon in a sustainable way? Biomass feedstock availability is and will be the limiting factor for the development of bioeconomy (energy, chemistry…) In France, 40-50 Mtoe in 2050 versus actual energy consumption of 280 Mtoe Two major consequences : i) Criteria of evaluation of the overall chains (GHG, energy balance…) and mainly ii) How to minimize the competition with food and feed? Global considerations

  3. Classical agriculture Byproducts Food/Feed Agriculture… 1992 Classical agriculture Byproducts Food and non food Agriculture 1992-2005… Dedicated agriculture Agriculture… tomorrow, An additional mission Food/Feed Byproducts Non Food Agriculture and Forestry are the two sources of renewable carbon [Land use competition]

  4. From the utilisation of the starch, sugars to the whole utilisation of the storage organ (grain, tubers…), …on the way of the biorefinery, To the use of the whole crop with one common factor, How to produce, to use this lignocellulosic raw material? Lignocellulose is the most ubiquist biomass feedstock at the world level, at the regional level : from agriculture to forestry ressources through biological urban wastes Lignocellulose, the challenge for the future

  5. The agricultural biomass feedstock, a learning curve from today to the future Potential C4 perennial crops Short rotation coppice Annual crops Byproducts straw Time

  6. By products such as straw… are limited in quantity but they exist today in the field. It is the first step for industrial applications Annual crops, an existing solution (triticale, sorghum…) but not the best in term of yield and sustainability, a solution for transition… C4 perennial crops, the best solution in term of productivity and local impact on environment, not yet ready for large scale use A panel of solution in time and space… Why this learning curve? (1)

  7. Why this learning curve? (2) Interest Where is the optimum? Triticale Miscanthus Insertion in farming system Triticale Miscanthus Environment Perennial crops Annual crops Crop perennity

  8. Lignocellulose, but which kind of process of conversion? Lignocellulose quality may be adapted, modified by green biotech more easily than productivity Evolution of quality during crop growth and its management Humid or dry biomass, thermochemical or biological process. One key-question for agriculture and related logistics Biomass feedstock and quality

  9. Size (200 000 t/y or 5 000 000 t/y), consequences are completely different Complementarity, synergy with other sources of biomass Impacts on farming systems Impacts on rural development Acceptability by actors of the chain including society Biomass feedstock and the industrial supply area

  10. Production Collecte Conversion Etapes [Agronomie] [Logistique] [Prétraitement / Synthèse] Produits Biomasse Intermédiaires Commodités Précondi- tionnement Broyage et/ou méthanisation Hydrolyse enzymatique Fermentation multi-sucres Ethanol Prétraitement Biomasse humide Intermédiaires de la lignine Biogaz + Energie Chaleur Electricité Co-génération + H2O © INRA / J.Cormeau Huiles Biomasse sèche Gazéification Synthèse Précondi- tionnement Broyage et/ou pyrolyse Conditionnement gaz et séparation Hydrocarbures Pyrolyse

  11. FUTUROL BIOFUELS2nd GENERATION PMII FUTUROL

  12. Aims of this project « Setup and validate, technically and economically, a process of ethanol production from lignocellulose » Adhoc research and development will be in relationship with a continuous pilot plant (scale of one ton per day), a preliminary step before an industrial demonstration plant. This pilot plant will be setup nearby a first generation distillery (from sugar beet).

  13. Biomass availability is the limiting factor and has to be produced in a sustainable way. Lignocellulose is the key raw material for tomorrow Perennial C4 crops is the ideal target in a panel of solutions to implement according to different socio, pedoclimatic conditions. This panel will include residues, annual crops, perennial crops and wood Conclusion (1)Biomass, a challenge for the XXIth centuryTowards a society based upon Bioeconomy?

  14. Conclusion (2) • Biomass ressources have to be defined (especially in term of quality) according to the industrial process, green biotech may be an important contribution • a key point for your seminar today! • Biomass requires large scale areas, acceptability and rural development are crucial questions
