Oil Seed Productivity

I am giving a talk at the Southern Coatings Society in March, and my talk is on coatings materials in a high petroleum cost world. I wrote the talk when prices were high, but now I am giving it when prices are low. Nonetheless, I am going to forge ahead. One of the issues is whether natural oils will ever be economical enough to replace petroleum based feedstocks. The answer is of course, but some oils are going to be cheaper than others. Some of the most popular oils are subsidized by the cost of co-products. For example, linseed oil is a coproduct with seed meal and flax fiber.

The following is a table of oil seed productivity. This table appeared in this form at journeytoforever.com by Ken Addison, but I suspect it is not original with him. Jouneytoforever.org is an interesting site. Maybe I will do a posting on their algae fuel analysis. <>
