WPI, the Bureau of Safety and Environmental Enforcement, and the U.S. Coast Guard Successfully Test a Novel Oil Spill Cleanup Technology
March 24, 2017 02:22 PM - Worcester Polytechnic Institute

Tests conducted this week of a novel technology that can greatly accelerate the combustion of crude oil floating on water demonstrated its potential to become an effective tool for minimizing the environmental impact of future oil spills. Called the Flame Refluxer, the technology, developed by fire protection engineering researchers at Worcester Polytechnic Institute (WPI) with funding from the Bureau of Safety and Environmental Enforcement (BSEE), could make it possible to burn off spilled oil quickly while producing relatively low levels of air pollutants.

The tests of the Flame Refluxer were conducted this week by WPI and BSEE at the United States Coast Guard’s Joint Maritime Test Facility on Little Sand Island, located in Mobile Bay. WPI is the first university to work on research at the facility since it reopened in 2015. The tests involved controlled burns of oil in a specially designed test tank on the island.

Google Street View Cars Are Now Helping to Track Methane Leaks
March 23, 2017 02:32 PM - Yale Environment 360

Google Street View cars have driven millions of miles across the globe, capturing 360-degree images of roadways and communities on all seven continents. Now, scientists and environmentalists are teaming up to add pollution trackers to the vehicles so they can monitor natural gas leaks as they drive.

The new project, detailed this week in the journal Environmental Science and Technology, is being led by researchers at Colorado State University, the Environmental Defense Fund, and Google Earth Outreach.

Wastewater cleaned thanks to a new adsorbent material made from fruit peels

Researchers from the University of Granada (UGR), and from the Center for Electrochemical Research and Technological Development (Centro de Investigación y Desarrollo Tecnológico en Electroquímica, CIDETEQ) and the Center of Engineering and Industrial Development (Centro de Ingeniería y Desarrollo Industrial, CIDESI), both in Mexico, have developed a process that allows to clean waters containing heavy metals and organic compounds considered pollutants, using a new adsorbent material made from the peels of fruits such as oranges and grapefruits.

Global CO2 Levels Stay Flat for a Third Year
March 23, 2017 09:00 AM - Steve Williams, Care2

Data shows that global CO2 emissions have remained roughly the same for the third year in a row. Although that’s good news for the fight against climate change, it’s important to put this data in perspective.

Natural gas leaks from power plants, refineries, 100 times greater than thought
March 22, 2017 05:02 PM - Steve Horn , Ecologist

Natural gas is meant to be a far lower carbon fuel than coal, writes Steve Horn. But a new study shows that methane leaks from gas power plants and oil refineries are 20-120 times higher than thought. And with methane a greenhouse gas almost 100 times stronger than CO2 over 20 years, the leaks are equivalent to about a tenth of the US's CO2 emissions.

Salmon with side effects
March 22, 2017 04:53 PM - Helmholtz Centre For Environmental Research - UFZ

Tasty, versatile, and rich in essential omega-3 fatty acids: salmon is one of the most popular edible fish of all. Shops sell fish caught in the wild, but their main produce is salmon from breeding farms which can pollute rivers, lakes and oceans. Just how big is the problem? German and Chilean scientists are working to answer this question under the leadership of the Helmholtz Centre for Environmental Research (UFZ). They examined the dissolved organic compounds which enter Chile's rivers from salmon farms, and have published a report in the journal Scientific Reports, warning that these substances are placing huge strain on ecosystems and are changing entire biological communities.
