Genbrug af kompositmaterialer fra industrien
Projekt bevilget af Styrelsen for Forskning og Innovation
Playground from wind turbine blade. End-of-life turbine rotor blades; A resource for design and architecture? Wind turbine blades used as building material for urban furniture
- It is predicted that in 2034 nearly 200,000 tonnes of blade waste is produced annually.
- The average lifespan of rotor blades is 10 to 25 years.
- 15,000 blades are sent to waste worldwide annually (and still increasing).
Wind turbine blade waste can be seen as structural and aesthetic elements for use in design and architecture worldwide. Blade made designs reduce wind energy waste and provide opportunity for later recovery of the valuable composite materials.
If only 5 % of The Netherlands’ yearly production of urban furniture such as playgrounds, public seating and bus shelters were made using waste rotor blades, then all of The Netherlands’ estimated 400 waste rotor blades produced annually would be removed from the waste stream.
Already implemented designs
Durable, indestructible seating with iconic quality. Waste streams: 9 x 6 m rotor blades, concrete rubble aggregate made from 100 % recycled concrete rubble.
playground with added value and smaller ecological footprint built for the same price as a comparable standard playground. Waste streams: 5 x 30 m rotor blades, fighter plane cockpit, Nike grind sports floor.
A blade as an iconic place marking signpost. Waste steams: 1 x 30 m rotor blade, waste steel sheeting, reclaimed window frames.
Durable and indestructible shelter. Waste streams: 4 x 30 m rotor blades.
Barriers for implementation
The use of wind turbine blades in architecture designs depends on both the waste streams available and the demand for these materials. So far, the implemented designs have been a success.
End-of-life wind turbine blades make an excellent building material for urban furniture and architecture designs. Using the materials in new designs are considered as Resize/Reshape, where the wind energy waste is reduced and provides the opportunity for later recovery of the materials.
