Using Ozone-Generated Bubbles to Remove Oil Sheen and Contaminants from Water

Green Car Congress

A University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters. Emerging contaminants, such as wastewater polluted with medications and personal care products.

Study: consumer products overtake transportation as largest source of VOCs air pollution in cities

Green Car Congress

The results, published in an open-access paper in the journal Science , suggest that the focus of efforts to mitigate ozone formation and toxic chemical burdens need to be adjusted, the authors suggested. Gasoline is stored in closed, hopefully airtight, containers and the VOCs in gasoline are burned for energy. McDonald et al.

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

In 1975, General Ernesto Geisel, then-president of Brazil, ordered the country’s gasoline supply mixed with 10% ethanol. The level was raised to 25% over the next five years, which was intended to maintain a constant Brazilian gasoline supply for an ever-increasing demand. These were arguably the first flex-fuel vehicles.

They accounted for both CO 2 emissions and emissions of ozone precursors (NO x , VOC, CO) and aerosols (BC or black carbon, OC, SO 2 ) as well as cloud effects (aviation-induced cirrus clouds and contrails)—i.e., 2 persons—and of transitioning from aircraft and cars to trains and coaches. fuel consumption.
