Its interesting that we havent seen a lot of turbines being cut up from Hydro dams. These wind things dont seem to last a lot of hours. We have a big wind farm up Island that had all the blades changed ,took 2 years and they buried them all.

Problem is the glass. As combustibles consume the glass precipitates out, plates to boiler or furnace surfaces. Is what they see of silica in PRB dirty coal in Fluidized boilers, really bad slag deposition.

The article said Veolia is using them for cement production, 70% glass which can be disposed of in cement with virtually no value, and 30% resin that can be burned in the kiln at a low percentage, and virtually no value. But big bucks to get rid of them, minus big bucks to grind them = profit. Seems to me the ground product would work great for concrete reinforcement, rather than replacing dirt in cement production.
