This is the 04/17/2013 update of the Biodiesel/Renewable Diesel margin report.
The above margin report are ESTIMATED margins for firms like:
Biox (BX.TO) (Link)
There is another firm in the alternative fuels category, Kior (NASDAQ:KIOR) (Link), but they do not use the feedstocks used in the above calculation. I include them only for completeness. The above margin calculation does not apply to them. If I can get feedstock and process data I may add them at a later date.
KiOR intends to use non-food sources of feedstock, such as wood and forestry residuals, while avoiding feedstocks such as corn or soy which are also used for food or are grown on land typically used for food production
From the above report SYNM continues to have superior margins with their renewable diesel, biodiesel firms like REGI and BX.TO show positive margins for most feedstock categories. Soybean oil biodiesel (SME) continues to show breakeven to negative margins.
In conclusion, renewable diesel and multi/flex feedstock biodiesel firms continue to show positive margins. The fact that SME continues to struggle bodes well for RIN prices and margins going forward (see "Info regarding RINs and EPA quota" below).
