Unfurling The Waste Problem Caused By Wind Energy

There aren't many options to recycle or trash turbine blades, and what options do exist are expensive... researchers estimate the U.S. will have more than 720,000 tons of blade material to dispose of over the next 20 years, a figure that doesn't include newer, taller higher-capacity versions.

Ninety percent of a turbine's parts can be recycled or sold, but the blades, made of a tough but pliable mix of resin and fiberglass — similar to what spaceship parts are made from — are a different story. "The blades are kind of a dud because they have no value," he said.

Englund believes he's found a way to recycle blades by grinding them up to make chocolate chip-sized pellets. They can be used for decking materials, pallets and piping.

Bolded bit relates to the recent discussion here about difficulty of recycling Trex decking boards, which are made of recycled plastic blended with sawdust. Of course, recycling wind turbine blades into Trex boards would only only kick the recycling can down the road. How would the boards be recycled once they are worn out? (Trex is struggling with recycling it’s boards).

On the positive side, if this guy's attempt at recycling turbine blades works out - that would beg another question - why can’t old Trex deck boards themselves be ground up into chocolate chip pellets that then get recycled into new Trex boards?

The saying "from ashes to ashes, dust to dust" may have to be replaced with "from deck board to deck board"...
