Separating rare earth metals with UV light

Researchers have discovered a method to separate two rare earth elements - europium and yttrium - with UV light instead of with traditional solvents. Their findings offer new opportunities for the recycling of fluorescent lamps and low-energy light bulbs.

Generating eco-friendly power with metal rotor blades

Wind turbines deliver environmentally friendly electricity. Yet the fiber-reinforced plastics often used in very large rotor blades are almost impossible to recycle. Not so with steel blades: since these are composed of steel, their recyclability exceeds 90 percent. Plus they cost significantly less than comparable plastic blades.

Many plastics labeled 'biodegradable' don't break down as expected

Plastic products advertised as biodegradable have recently emerged, but they sound almost too good to be true. Scientists have now found out that, at least for now, consumers have good reason to doubt these claims. In a new study, plastics designed to degrade didn't break down any faster than their more conventional counterparts.

Recycling aluminium, one can at a time

Producing pure aluminium from ore accounts for as much as 1 per cent of all greenhouse gas emissions worldwide. Recycling is the best way to reduce that carbon footprint - but manufacturers and recycling companies will have to plan carefully to avoid problems with impurities that accumulate in recycled aluminium over time.

Wood-derived foam materials

Since most foam materials are made of petrochemical plastics, they aren't very climate-friendly. But now an alternative is in sight - a novel foam material produced entirely from wood, which is not harmful to the environment and is also recyclable. In the long term, wood foam could replace conventional products used for thermal insulation, packaging.
