• Wind energy and more specifically the use of wind turbines to generate electricity, is an exploding market.
• the prospect of recycling wind turbine blades may be attractive and consistent with the notion of wind energy as a "green” power source, it has not previously been technically or economically feasible.
• experts have regarded wind turbine blades as "unrecyclable” and a problematic source of waste. See Liu et al., "Wind Turbine Blade Waste in 2050," Waste Management, Vol. 62, pp. 229-240 (April 2017). With the growing importance of wind power in worldwide energy production, this problem will only get worse.
• Tracking the status of wind turbine blades in a recycling process is important for several reasons. For example, as suggested above, such a tracking system would allow turbine owners, utilities, or certification organizations to determine whether blades have been recycled properly and to correlate each recycled blade and its raw material that can be used for feedstock for various products. As another example, a tracking system would allow recyclers to adjust or redesign recycling processes to achieve further productivity and quality gains. In addition, when recycled blades are transformed into useful raw materials, the tracking system would provide manufacturers with additional intelligence to improve the productivity and quality of their manufacturing processes.
