Current needs
ƒ Improve material supply from land based
industries – prioritise need
ƒ Joined up research to deliver biotechnology
solutions
ƒ Identification of key chemical building blocks
ƒ Greater knowledge of, and optimising, high yield
conversion methods & co-product uses
ƒ Properties and performance
Identify & map pathways to success
Current needs
ƒ Need to identify new uses for chemicals from
biomass – new functionalities
ƒ Significant financial support
Current needs
ƒ Environmental benefits need to be defined
and marketed more effectively
ƒ cradle to grave LCA’s
ƒ Recognisable marketing logos
ƒ Retaining added value in the rural community
