2 Energy demand  It is estimated that the current consumption of petroleum is at a rate 100.000 times faster than nature can replace it. Alternatives: Wind Solar Nuclear Hydro Biomass

3 Biomass is the only non-fossil option for organic chemical production. http://cr.middlebury.edu/es/altenergylife/sbiomass.htm

5 A pathway from biomass to platform chemicals Raines, R. T.; Binder, J. B. J. Am. Chem. Soc. 2009, 131, 1979-1985

6 Ionic Liquids + Metal Catalysts  Ionic liquids are low melting organic salts (<100 0 C) that potentially comprise wide application due to their fascinating properties and have emerged as promising “green” replacement for volatile organic solvents.  Like the conventional salts, ionic liquids are mainly composed of ions which are positively and negatively charge.  The most attractive properties of ILs are their chemical and thermal stability, non-flammability, and negligible vapour pressure.
