Pitt engineers using membrane distillation to recycle water used in fracking and drilling

Green Car Congress

Engineers at the University of Pittsburgh Swanson School of Engineering are using membrane distillation technology to enable drillers to filter and reuse the produced water in the oil and gas industry, in agriculture, and other beneficial uses. The team is back in the lab to find a fix. Shamlou, Elmira & Vidic, Radisav & Khanna, Vikas.

Study finds renewable fuels from hydrotreated vegetable oils outperform transesterified lipids and BTL from woody material in environmental lifecycle impacts and costs

Green Car Congress

GHG emission comparison between fossil diesel, transesterified lipids, HVO and woody BTL. GD = HVO; RSO = Rapeseed Oil; SBO = Soybean oil; Biodiesel = Transesterified lipids. This is due to a combination of low energy efficiency and higher feedstock impacts of short rotation forestry than wood from waste and forestry.

New study suggests reported PAH emissions in oil sands region greatly underestimated

Green Car Congress

Results from a new modeling assessment of contamination in the Athabasca Oil Sands Region (AOSR) suggest that officially reported emissions of polycyclic aromatic hydrocarbons (PAHs) in that region have been greatly underestimated. —Parajulee and Wania.

Comparison of power loss and fuel consumption among BD, HVO and iso-HVO. For the study, the biodiesel (Fatty Acid Methyl Ester) consisted of a mixture of 80% palm-based methyl ester (PME) and 20% biodiesel derived from waste cooking oil—a typical blending ratio of commercial biodiesel in Korea.

Converting Oil Shale to Gasoline via Alberta Taciuk Processor Results in Full Fuel Cycle GHG Emissions 1.5-1.75 Larger Than From Conventionally Produced Gasoline

Green Car Congress

Converting oil shale to gasoline via the Alberta Taciuk Processor (ATP)—an above-ground shale retort—results in fuel-cycle greenhouse gas emissions of ~130-150 g CO 2 equivalent/MJ of gasoline produced, according to a new analysis by Dr. Adam Brandt at Stanford University.

EcoSystem Launches Fly Larvae Feedstock Model for Food Scrap Biodiesel

Green Car Congress

EcoSystem Corporation has introduced its MAGFUEL biofuel feedstock model that uses the larvae of Black Soldier Flies ( Hermetia illucens ), which consume and metabolize food scrap waste. The larvae dry weight consists of about 42% protein and 35% natural oils. The natural oil derived from the Black Soldier Fly larvae consists of: 1.6%
