This mini-review describes the concept of the green biorefinery and lists a number of suitable agricultural by-products, which can be used for production of bioenergy and/or biochemicals. A process, in which one possible agricultural by-product from the green crop drying industry, brown juice, is converted to a basic, universal fermentation medium by lactic acid fermentation, is outlined. The resulting all-round fermentation medium can be used for the production of many useful fermentation products when added a carbohydrate source, which could possibly be another agricultural by-product. Two examples of such products-polylactic acid and L-lysine-are given. A cost calculation shows that this fermentation medium can be produced at a very low cost approximate to 1.7 Euro cent/kg, when taking into account that the green crop industry has expenses amounting to 270,000 Euro/year for disposal of the brown juice. A newly built lysine factory in Esbjerg, Denmark, can benefit from this process by buying a low price medium for the fermentation process instead of more expensive traditional fermentation liquids such as corn steep liquor.
