Escape the Oil Trap

§ Biomass is the only carbon containing renewable resource

Ø Biomass used for chemical production prior to energy generation

§ Syngas and Methanol are the key to synthetic products

Ø Broad and flexible product range for energy and chemistry

§ Adoption of proven technologies and existing infrastructure

§ Structural redirection in agriculture and forestry

ØNew income source and employment for agriculture

The Development of Routes to Chemicals based onBiomass is the Winning Option in Future

Biomass can cover 30%+ of the primary energy demand,but should primarily be used as Carbon Source

Biomass is the Key Alternative for Oil and Gas

Chemicals based on Biomass Need :

- Basic research- Regional Demonstration - Industry Building embedded in Long Term Programs >10 years- Sustainable Support by Legislation
