Study shows biodiesel improves workplace health

A recent pilot study from the Air & Wast Management Association compared diesel and biodiesel B20 exhaust, measuring the the occupational exposure to particulate matter (PM) and other air toxins. Biodiesel B20 was found to reduce harmful pollutes in the work environment.

The study was conducted at  a New Hampshire recycling facility, heavy equipment exhaust was measured while running petroleum diesel and then on B20 biodiesel.

The technical paper describe, the study “used a combination of established industrial hygiene and environmental air monitoring methods to estimate occupational exposure profiles to PM and air toxics from combustion of petroleum diesel and biodiesel. Results indicate that B20 use dramatically reduces work area respirable particle and formaldehyde levels compared with petroleum diesel.”
