Terry, I believe even more products could be made from the first output of the cellulosic process, which is sucrose(sugar). The choice involves markets, price/profits of the final product, and cost/ease of revising the process after sugar extraction to make the chosen final product.
Ethanol conversion from cellulosic sucrose is well-known, has a huge potential market, and its profitability seems to be good, especially for companies that do not have to purchase corn as their raw material. The choice of final product could actually vary from one country to another, depending on market considerations. It is even possible for one plant to produce multiple products, using several plant units with different designs.
