Companies as well as organizations are looking at biodiesel to supply their fuel needs.  I know that before they invest in biodiesel, they will be doing their own Biodiesel Feasibility Study.  This will tell them if there are any ROI (or return of investment).  This study can also forecast the profits they will be able to make per month and how long it would take for them to get their money back.  This is important so these investors will know what to expect and how they will be able to use, promote and make biodiesel.
