Armacell offers 100% recyclable PET structural core foam for wind turbine blades.

Wind energy: Ultimate in foam quality

Enabling sustainable growth through patented PET recycling technology for composite core materials.

Wind power is a cost-competitive means of energy generation that better contributes to environmental sustainability.

Wind power is an environmentally-friendly form of cost-competitive energy generation. Sustainability and low Levelised Cost of Energy (LCoE) ambitions motivate manufacturers and OEM companies to work with reliable and innovative partners to achieve these goals. Accounting for more than 6% of global electricity generation, wind energy is a positive contributor towards sustainability, and drives the need for bigger and more efficient rotor blades.

Rotor blades are key components that play a definitive role in determining the amount of energy generated in a wind turbine.

Manufacturers must manage the fine balance of the challenges associated with physically larger rotor blade diameters against achieving optimal performance in view of more demanding mechanical and wind loads. Wind turbines with larger rotor blade diameters can, for example, be placed in lower wind speed areas and also in off-shore locations. Hence, rotor blade designs and materials are continuously reviewed and improved.


While 85% of turbine components can be either recycled or reused, blades are difficult to dispose. For better environmental sustainability and total cost of ownership, manufacturers aim for ease of processing during blade manufacturing, and an extended lifetime performance for rotor blades.
