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.

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.

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.

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.
