"Towards Substitution of Hexane as Extraction Solvent of Food Products and Ingredients with No Regrets":

> The extraction process is the same for all eight types of oilseeds subject to this rule (soybean, cottonseed, canola, corn germ, sunflower, safflower, peanuts, and flax). In each case, the seeds are crushed and mixed with the solvent. The oil then dissolves in the solvent. Following this step, the solution is separated from the seeds and heated to evaporate the solvent. The evaporated solvents are then condensed and reused in the process. […] This standard restricts plant-wide hexane emissions from each affected facility rather than requiring individual controls at each emission point.

yeah, hexane is the industry standard for extraction... even bio oils are tied to petroleum.

here is comparison on extraction physics vs chemistry for turning it into biodiesel - https://vectree.io/compare/biodiesel-chemical-engineering-vs...
