187b No waste! Biorefinery is amazing example of industrial symbiosis

On this week's CKUA Green Energy Futures feature: Industrial symbiosis. Corn comes into a biorefinery that produces ethanol, industrial alcohols, corn oil, and distillers' grains. And then ALL wastes from this plant are used as well to heat a greenhouse, grow tomatoes and much, much more. It's a virtuous cycle of products and wastes, that each turn are used to produce other products.
