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 relying on “local food” a distant dream for most of the world

Green Car Congress

A study by an international team of researchers led by Aalto University finds that less than one-third of the world’s population could currently meet their demand for food with food produced in their local vicinity. In comparison, the global average is about 3,800 kilometers. The paper is published in the journal Nature Food.

Study on Greenhouse Gas Emissions from Global Cities Highlights Importance of Geophysical and Technical Factors

Green Car Congress

An international study of 10 global cities found that a balance of geophysical factors (climate, access to resources, and gateway status) and technical factors (power generation, urban design, and waste processing) determine the greenhouse gas emissions (GHGs) attributable to cities.
