Biodiesel improves mineshaft air quality: report

In Missouri, the Mine Safety Health Administration has released a report showing how the use of biodiesel in mines significantly improves the air quality in mines. Hutchinson Salt Company in Kansas was the first mine of any kind to use B99 biodiesel (a 99 percent biodiesel fuel mix). Since 2003, the company has used between 17,000-30,000 gallons of B99 a year, depending on the demand for salt.

Their employees noted cleaner air in the mines within days after the switch to biodiesel. B99 powers all their underground diesel equipment, ranging from loaders to diesel pickups to tractors.
