I am doing some research on biofuel production and the relationship of this use to zoning classifications. More specifically, I am doing research on soybean oil and the processing of this oil for biodiesel production. A landowner is attempting to produce biodiesel from soybean oil on his property which is currently zoned agricultural. I am trying to find any examples of biofuel operations located on land zoned agricultural. So far, the biofuel operations I have found have been located on properties zoned industrial. Any studies or resources related to this topic would be appreciated as well.
