Study finds PM from biodiesel blends may be 50-80% less toxic per unit PM mass than from petroleum diesel

Green Car Congress

In a study published in the ACS journal Energy & Fuels , a team from the University of Vermont reports that particulate matter from the combustion of biodiesel blends may be 50–80% less toxic per unit PM mass emitted than PM from petroleum diesel, depending on feedstock. PM-normalized DTT Activity for biodiesel exhaust PM.
