The distiller’s grain from an ethanol plant that consumes 15 million bu of corn per year has a furfural potential in the order of 8,000 tons (7,300 metric tonnes) per year. This translates into US$8 – $12 million revenue or ±US$80 per tonne of DDSG..
Furfural is produced from the hemicellulose fraction (of the distillers grain), which has no/low nutritional or energy value.
The balance of the distiller’s grain is still usable e.g. for animal feed (with an enriched protein and fat content!), biopolymers (example), etc.
