Billions of pounds of plastic waste are littering the world’s oceans. Now, a Ph.D. organic chemist and a sailboat captain report that they are developing a process to reuse certain plastics, transforming them from worthless trash into a valuable diesel fuel with a small mobile reactor. They envision the technology could someday be implemented globally on land and possibly placed on boats to convert ocean waste plastic into fuel to power the vessels. The researchers will present their results today at the 253rd National Meeting & Exposition of the American Chemical Society (ACS).

The Supreme Court will not pause a case concerning the Obama administration’s Clean Water Rule in a rebuke to the Trump administration.
The justices’ decision came on Monday with no explanation.
In March, Oregon DEQ finalized its much-anticipated strategic plan for the preventing of wasting of food. The plan outlines a framework to direct DEQ’s work over a five-year period to encourage reductions in the wasting of food across the supply chain to support Materials Management in Oregon: 2050 Vision and Framework for Action.
Drawing on an eight-month long evaluation of the current landscape around preventing the wasting of food and an assessment of more than 80 potential projects, DEQ has identified nine projects that it believes will both “change the current conversation” around preventing the wasting of food and make significant, measurable contributions to the state’s waste reduction goals.
The first project is a major research effort into the causes, quantities and types of wasted food in Oregon. Other projects include the development of public information materials; engagement with commercial food service businesses; collaboration with the edible food donation and rescue community; supporting efforts to decrease public confusion around sell-by, use-by, and best-by date labels; and pilot projects in school kitchens.
The full strategy can be found here.

There are emerging concerns about organic micropollutants such as pesticides, pharmaceuticals and personal care products due to their potential adverse effects on environmental ecosystems and the public health. Wastewater treatment plants (WWTPs) are a major sink for down-the-drain chemicals and thus play a key role in their environmental fate. Strong associations have been observed between ammonia oxidization activities and the biotransformation of some micropollutants. However, whether there is a causal relationship between those two remains unclear. Batch scale pure culture and inhibition studies, as well as micropollutant removal investigation for a full scale enhanced nitrification step at local WWTPs have been applied to get a better understanding of roles played by ammonia oxidizers. Various types of evidence indicate essential involvement of nitrifying microorganisms in the biotransformation of certain micropollutants. For above half of the micropollutants investigated, the biotransformation of micropollutants in WWTPs achieved by heterotrophs or a combined contribution of heterotrophs and nitrifiers. The findings provide important insights into the persistency of different micropollutants during biological wastewater treatment processes.

They are the chemicals that made consumers think twice about using nonstick cookware. New research in the journal Environmental Science & Technology Letters shows scientists have developed a method to track perfluorinated alkyl substances (PFAS) in the body. PFAS are potentially toxic chemicals found in stain-resistant products, nonstick cookware, fire-fighting foams and — most recently — fast food wrappers.

“Resilience” is a buzzword often used in scientific literature to describe how animals, plants and landscapes can persist under climate change. It’s typically considered a good quality, suggesting that those with resilience can withstand or adapt as the climate continues to change.
But when it comes to actually figuring out what makes a species or an entire ecosystem resilient ? and how to promote that through restoration or management ? there is a lack of consensus in the scientific community.
A new paper by the University of Washington and NOAA’s Northwest Fisheries Science Center aims to provide clarity among scientists, resource managers and planners on what ecological resilience means and how it can be achieved. The study, published this month in the journal PLOS ONE, is the first to examine the topic in the context of ecological restoration and identify ways that resilience can be measured and achieved at different scales.
