1. NEW CROPS FOR BIOFUEL/BIOPRODUCT PRODUCTION AND THE FEEDSTOCK READINESS PROFILE ABFC, NEW ORLEANS,JUNE 2015 Processing Research since 1892

2. FEEDSTOCK READINESS CHART THE INFORMATION FLOW FOR DEVELOPMENT NEEDS INCLUDE ALL STAKEHOLDERS. Research Producers Government Processors Financiers The feedstock readiness chart is a useful tool, although linear in its approach, It goal is to be an information source to bring a feedstock to market. We have been working on two new crops for fuel production.
