Recycling Renewable Energy-Seems like a natural but is it?

I was kind of pulled out of my chair this morning when I was reviewing some news feeds and came across this article.

Richard Gross, a professor of chemical and biomolecular engineering at the Polytechnic Institute of New York University (NY-Poly), is deeply troubled that clean energy technologies meant to help preserve the planet employ nonsustainable, petroleum-based materials.
"The blades on a wind turbine, for example, are massive and need to be replaced about every 25 years," Gross said. "They end up in landfills, like any other nonrecyclable garbage."
This a clip from "When Wind Turbine Blades and Solar Panels End Up in Landfills" published in Electric Light&Power. What seems quite improbable to me is the statement by Professor Gross that a lot of the equipment used for sustainable "green" power ends up in landfills! What's going on with this. So I started doing some research for other articles and sources to support the professor's claim. [see delicious and search for recycle wind turbines]

I also looked back at the source of the information. Professor Gross has his own axe to grind here since he is looking for practical application for his research in bimolecular engineering. I'd add to his cry for other building materials which often end up in the landfills. For example, how about porcelain fixtures that get thrown out. Can they be ground up and re-purposed again? How are we recapturing the heavy and toxic chemicals used in PV based panels. Are a lot of these ending up in landfills, or not.
