This is the link t the article that I found:
http://domesticfuel.com/2013/10/22/biodiesel-supply-curve-key-to-rin-price-structure/
It is about supply of biodiesel in the US. The unversity of Illiois estimated the supply curve of biodiesel this year. The shape of the curve is rather exponential - the slope of the curve increases as the quantity increases. And the price elasticity drastically decreases as the quantity increases.
