Reclaiming rare earths: Improving process to recycle rare-earth materials
Reclaiming rare earths: Improving process to recycle rare-earth materials
Posted: 24 Oct 2012 02:55 PM PDT
Recycling keeps paper, plastics, and even jeans out of landfills. Could recycling rare-earth magnets do the same? Perhaps, if the recycling process can be improved. Scientists are working to more effectively remove the neodymium, a rare earth element, from the mix of other materials in a magnet. Initial results show recycled materials maintain the properties that make rare-earth magnets useful.2012 Antarctic ozone hole second smallest in 20 years

The average area covered by the Antarctic ozone hole this year was the second smallest in the last 20 years. Scientists attribute the change to warmer temperatures in the Antarctic lower stratosphere.Speed limits on cargo ships could reduce their pollutants by more than half

Putting a speed limit on cargo ships as they sail near ports and coastlines could cut their emission of air pollutants by up to 70 percent, reducing the impact of marine shipping on Earth’s climate and human health, scientists have found. -

Our protective magnetic bubble lets the solar wind in under a wider range of conditions than previously believed. Earth’s magnetic field is our planet’s first line of defense against the bombardment of the solar wind. This stream of plasma is launched by the Sun and travels across the Solar System, carrying its own magnetic field with it. Depending on how the solar wind’s interplanetary magnetic field – IMF – is aligned with Earth’s magnetic field, different phenomena can arise in Earth’s immediate environment.You are subscribed to email updates from ScienceDaily: Severe Weather News

Methane conversion makes piggery carbon neutral
Methane conversion makes piggery carbon neutral

A pig farm in central-western New South Wales has started converting methane from the animals’ manure into electricity, to become the first piggery to completely offset its carbon emissions.
The electricity generated is helping power the farm at Young.
Federal Parliamentary Secretary for Climate Change Mark Dreyfus is officially launching the project that entitles the farmers to earn carbon credits for capturing the gas.
The farm’s owner, Edwina Beveridge, says it has been a huge success.
“We’re the first farm,” she said.
“I believe the people before us are flaring land fill gas, so we’re the first farm, first people in New South Wales, first pig farm, first of a lot of things.
“I will have to do some calculations based on the electricity we generate. A rough estimate we expect that we might be able to earn $80,000 a year.”
The piggery no longer has power bills as a result of the project.
“Our electricity and gas bill combined used to be about $15,000 a month,” Ms Beveridge said.
“We are now earning $5,000 a month with selling excess electricity. The project has, we think, a three-year payback period, so you can do the maths.
“It’s nice to be at the head of the pack.”
