The Spokesman-Review: Watching their waste
Published: DECEMBER 15, 2009
…within a year the Barr Regional Bio-Industrial Park could be ingesting 75,000 tons of municipal, commercial and farm waste. The material will be converted into fertilizer, enough electricity to supply 1,000 homes, and substitutes for some of the chemical industry’s petroleum-based raw material. Nothing will be wasted.
Other waste that contains high-energy materials such as fats, food, even greasy pizza boxes, will go into the digester, which contains a “soup” laden with bacteria. As they consume the waste, the bacteria produce methane that will be burned in two one-megawatt generators, with a third to be added later. One megawatt can meet the electricity needs of 500 homes.
Chief Operating Officer Devin Elliot said the Seattle company can process some of the mixture into anhydrous ammonia and chemicals used in cosmetics, paints and plastics.
Blue Marble has another use for the digester.
Elliot said Blue Marble, although it has the word “Energy” in its name, will focus on making high-value organic compounds because they are more profitable than bio-fuels.
