9. Conclusions/Summary

10. Programmatic information Here are some extra slides that show the biorefinery pathways with the specific Product R&D related milestones, Product R&D technical barriers (from Products R&D Multi-Year Technical Plan), and stage gate process slide (see stage gate guide). You do not need to include them in your presentation except to identify which biorefinery pathway/milestones your project supports, technical barriers your project addresses, and what stage your project is in as per the stage gate guide. Also, if youd like to comment on our milestones in the pathways - are they appropriate/specific enough or should they be more detailed/how.
