From Waste to Wind – Durable ASA Wind Turbine Blades with Steel Spar

High-strength | Weather-resistant | Custom hub mounting | Made for real outdoor use

Upgrade or build your own small wind turbine with robust, precision-made blades designed for reliability and long service life.

Our blades are manufactured from ASA (UV- and weather-resistant engineering plastic) and reinforced with an internal steel spar, giving them the strength and stiffness needed for real-world wind conditions — not just light hobby use.

Unlike standard 3D-printed or plastic blades, these are built to handle continuous outdoor exposure and winds up to 11 m/s with confidence.

Features

• Winglets for quiet operation and high efficiency
• Rated up to 11m/s, at which the blades produce 1100W mechanical power (for other windspeeds, check the powercuves in the images)
• ASA construction – UV, rain, and temperature resistant
• Integrated steel spar – high rigidity and durability
• Multiple TSR options available – optimize for torque or speed. Price is the same, just message us if you want another TSR than 5 (min 3. max 6).
• Different blade lengths will be available soon, message us if you want them earlier.
• Custom bolt pattern possible for your hub (the spar does NOT come predrilled with mounting holes).
• Ready for DIY and small wind systems
• Designed and made by FromWasteToWind

Why ASA + Steel?

ASA keeps its strength and shape outdoors (unlike PLA/PETG), while the steel spar prevents flexing and fatigue. The result is longer life, safer operation, and better efficiency.

Flexible mounting

Bolt holes in the spar can be made to match your hub, or we can recommend common bolt-on hubs.

Ideal for

• DIY wind turbines
• Off-grid systems
• Educational projects
• Small power generation
• Experimenters & makers
• Repair or upgrade of existing turbines

Built with a sustainability mindset and practical engineering.

If you need a specific diameter, TSR, color or bolt distance/size — just message us.
