Abstract

REHINK*ROTOR develops concepts for the complete use of rotor blades from dismantled wind turbines in the construction sector. Cross-industry circular economy: REHINK*ROTOR supports the way out of the recycling dilemma: leaving the huge blades in the anthroposphere not only enables a significant CO2 reduction, but is also more sustainable than their material recycling due to the reuse of the complete rotor blades. The aesthetic potential of the blades, their durability, corrosion resistance, lightness and stability add value to the construction industry. New lifecycle: the reuse of rotor blades reduces the consumption of raw materials and energy and the generation of waste. Acceptance promotion: due to its sustainability, REHINK*ROTOR stands for a visibly comprehen-sible, social added value and has a positive influence on the public perception of wind energy. Construction: approx. 90% of all mineral raw materials used in Germany are used for the produc-tion of building materials. The construction industry is a major contributor to waste generation. Buildings account for 40% of the total energy demand, so that resource-saving construction is of particular importance. Wind energy: With 22% of gross electricity in Germany, wind energy is a rapidly growing market, but wind turbines have to be dismantled after 20 years - in Germany alone, 7500 blades every year. Blades can only be partially recycled through costly, environmentally harmful processes. This is not done residue-free, neither CO₂-neutral, nor sustainable! Some are therefore shredded and metal residues contained therein are separated. Goal: The knowledge and gray energy in each wind rotor blade is permanently lost if it is not re-used. In the cross-sector reuse of blades, REHINK*ROTOR links creative energy, new technologies and sustainability goals, include contributing visible social value to the energy and building tran-sition and promoting public acceptance of wind energy.
