Bhutan's stumbling block to becoming the greenest nation on the planet
March 1, 2017 09:48 AM - The Ecologist - Michael Buckley

Bhutan is well on its way to becoming the greenest nation on the planet. In his Special Report for the Ecologist, Photojournalist MICHAEL BUCKLEY explores the reasons why the country's ecosystems and dazzling biodiversity remain intact - and highlights the one thing that threatens this admirable integrity...

U of T research could help sponge up oil sands wastewater
March 1, 2017 09:15 AM - University of Toronto

In theory, oil and water don’t mix. In reality, the two liquids can be almost impossible to separate, especially from complex chemical cocktails such as the wastewater produced by Alberta’s oil sands mining operations.

40-year trend study finds signs of improved water quality in New Jersey streams
March 1, 2017 08:57 AM - United States Geological Survey (USGS)

A USGS analysis of New Jersey water quality trends found levels of total nitrogen and total phosphorus, which fuel algae blooms, declined or stayed the same at most stream sites between the 1970s and 2011. At all sites studied, chlorides from road salt increased over that time.

New use for paper industry's sludge and fly ash in plastics
February 27, 2017 03:11 PM - VTT Technical Research Centre of Finland

VTT Technical Research Centre of Finland examined, as part of the EU's Reffibre project, whether new industrial applications could be developed for various types of sludge and fly ash generated by the paper and board industry.  Laboratory tests showed that these side streams can replace up to 50% of oil-based polypropylene. They can be used as a raw material in plastic composites made using injection moulding and extrusion.

Scientists: Warming temperatures could trigger starvation, extinctions in deep oceans by 2100
February 24, 2017 08:25 AM - Oregon State University

Researchers from 20 of the world’s leading oceanographic research centers today warned that the world’s largest habitat – the deep ocean floor – may face starvation and sweeping ecological change by the year 2100.

Transforming restaurant waste into fuel
February 22, 2017 08:16 AM - University of Saskatchewan

When most people look at discarded vegetable oil—browned and gritty from frying food—they likely see nothing more than waste.

But to Ajay Dalai, a professor in the Department of Chemical and Biological Engineering, the cooking process creates a byproduct that has newfound potential as a source of fuel and biolubricant.

Fifth of food lost to over-eating and waste
February 22, 2017 07:00 AM - University of Edinburgh

Almost 20 per cent of the food made available to consumers is lost through over-eating or waste, a study suggests. 

The world population consumes around 10 per cent more food than it needs, while almost nine per cent is thrown away or left to spoil, researchers say.

Efforts to reduce the billions of tonnes lost could improve global food security – ensuring everyone has access to a safe, affordable, nutritious diet – and help prevent damage to the environment, the team says.

Offshore Wind Push
February 21, 2017 03:28 PM - University of Delaware

Injecting large amounts of offshore wind power into the U.S. electrical grid is manageable, will cut electricity costs, and will reduce pollution compared to current fossil fuel sources, according to researchers from the University of Delaware and Princeton University who have completed a first-of-its-kind simulation with the electric power industry.
