Oregon company to turn dairy waste into butanol
Diesel Brewing of Salem plans to burn either dairy or wood waste to create liquid butanol through a process called gasification.
Butanol is a form of alcohol that could completely replace petrol rather than be blended with it, like ethanol.
CEO Jeff Raines and his business partners are planning to open a pilot plant in Salem, Oregon, by the end of 2009.
The test plant would use between half a tonne to a tonne of wood and dairy waste per day. If the process proves workable, Raines and his team hope to build commercial-scale plants that use 100 tonnes of waste per day and produce a couple million gallons of butanol per year.
