The CME site describes the components of the spread/crush which is also referred to as a "board margin."
From this calculation you get the gross margin but you have no idea if it's a negative margin or extremely profitable for a plant (or the industry) unless you know something about operating costs and the basis at which they buy beans and sell meal and oil.
It's not that difficult to find basis levels, but to paraphrase Nazzdack, good luck on finding the plant's operating costs. You might have some success on trade association sites or in an academic paper, but as with any manufacturing facility, especially one in the price sensitive commodity business, they don't post their costs of production on the factory gate.
