coproducts become more important
With veg oil prices sky high and the spread between veg oil and diesel negative, the importance of co-products is increasing. If a biodiesel producer can significantly increase revenue from glycerine or other co-products, they may be able to make up the negative spread. A group in Brazil is claiming they can make "green propane" out of glycerine. I have reviewed many of these so called technologies and most dont have good energy balance. But at these prices maybe. Unfortunately the Brazil team is saying 2013 until commercial production. Add 5 more years because it is Brazil. Not something t help biodiesel today. The best thing is to simply refine to technical grade glycerine. That takes your price from $.12/lb to over $.25/lb.
