Oregon construction firm uses biodiesel to eliminate diesel odor at hospital site
But the point of the article is not biodiesel's well-known French fry smell, but that more and more construction firms in Oregon are turning to biodiesel as an alternative fuel for their equipment. Brewer is working on the site for an expansion of Portland's hospital where patients and staff used to complain about diesel exhaust odors. The anti-odor solution was to switch to biodiesel (after the workers tried to pump the exhaust through a "jury-rigged metal conduit" away from the building. That didn't work).
Another company, Portland's Walsh Construction Co., uses B20 in its delivery trucks.
