Certainly.
The aspartic acid program that was initiated here a few years back has hit a typical roadblock, and that is that it's competing with a petroleum-based product. As long as the petroleum-based products are hovering in the $100-per-barrel range, it is not practical to make aspartic or polyaspartic acid from sugar beet residue. Once the cost of a barrel of oil goes up, then it becomes competitive, but right now that particular project is stalled because of the price of a barrel of oil and the competitive nature of it.
