With the rapid growth of wind energy, many old wind turbines are being decommissioned and replaced with newer, more efficient models. This presents an exciting opportunity for DIYers and makers to salvage useful materials from old wind turbine parts for innovative upcycling and repurposing projects. From blades, generators and gearboxes to transformers, towers and nacelles, wind turbines contain a diverse range of high-quality components that can find new life in clever hands.
Salvaging and repurposing wind turbine materials aligns with principles of the circular economy by reducing waste, extending product lifetimes, and breathing new creativity into discarded resources. This article offers guidance on how to identify valuable salvageable parts in decommissioned wind turbines and transform them into functional and artistic DIY creations.
Locating Decommissioned Wind Turbines
The first step is finding a decommissioned wind turbine to harvest materials from. Here are some tips on where to look:
Wind farms – Contact wind farm operators directly to ask if they have old turbines scheduled for decommissioning that you could salvage from.
Sellers/resellers – Various online sellers and resellers specialize in selling used, salvaged wind turbine parts. Search for terms like “used wind turbines for sale”.
Auctions/liquidations – Search auction sites and listings for upcoming wind turbine liquidations. Components like blades may be sold in lots.
Dismantlers – Companies focused on decommissioning wind farms may be open to you salvaging components before dismantling.
Networking – Talk to wind industry professionals to learn about upcoming decommissioning projects with salvage potential.
Assessing Site Safety and Access
Before salvaging any materials, ensure you can do so safely and legally:
Get written permission from the wind turbine owner/operator to be on the site and remove components.
Verify there are no major safety hazards that could impact salvage activities.
Use proper safety gear and equipment like harnesses, helmets, gloves, etc. Work with experienced professionals if unfamiliar with safely dismantling wind components.
Determine if you will need to rent heavy machinery/equipment like cranes or lifts to remove and load larger parts.
Comply with all regulations related to transporting oversized loads if moving components on public roads.
Identifying Valuable Components to Salvage
Here are some of the most useful and practical components to target when salvaging old wind turbines:
- The long, aerodynamic composite blades are a versatile material for projects. Their size makes them ideal for unique building structures or art installations.
- Salvage them safely using appropriate tools. Blade lengths often exceed 50 meters.
- These contain useful metals like copper and neodymium magnets which can be repurposed.
- Generator housings or casings provide sturdy metal material as well.
- Durable metal gears of various sizes can be reused in new machines.
- Gearbox housings offer stable structures for building projects.
- Copper wire windings and laminated iron cores have reuse potential.
- Transformer housings provide sturdy steel material.
- Tower wall sections can be reused as strong structural beams or columns if properly dismantled.
- Ladders, rails and platforms have functional reuse possibilities too.
- The rear nacelle covers offer stable shell structures for enclosing DIY builds.
- Various motors, pumps, cables and electronic components may also be salvageable.
Fasteners and Hardware
- Don’t overlook small nuts, bolts, screws and mounting hardware which often go to waste but can be reused in projects.
Transporting and Storing Salvaged Materials
Consider logistics for transporting and storing salvaged components:
Determine adequate vehicle sizes and load capacities for large, long parts like blades.
Identify suitable indoor and outdoor storage space for components, especially if working on projects over long durations.
Use proper lifting and rigging equipment like cranes, dollies, lifts, etc. to safely load, move and position awkwardly shaped parts.
Safety Working with Salvaged Materials
When working on DIY projects with salvaged wind components:
Wear appropriate safety gear – eye protection, dust masks, gloves, steel-toed boots, etc.
Follow safe procedures for cutting, grinding or machining materials. Use correct tools and ventilation.
Support large parts appropriately if working underneath them.
Check for hazardous substances like lead paint or fiberglass and take precautions.
Get expert help if unsure how to safely handle, alter or work with any salvaged components.
Creative Ideas for Upcycling Wind Turbine Parts
Now the fun begins! Here are some innovative examples of how DIYers have upcycled wind turbine materials:
- Convert a blade into a garden bridge or decorative gateway.
- Use tower sections as structural beams in buildings or sculpture frames.
- Craft generator housings into coffee tables or computer workstations.
- Repurpose gear mechanisms into kinetic sculptures or steampunk furniture.
- Build tiny homes or sheds from repurposed nacelle, hub or rear covers.
- Fashion necklaces, keychains or table bases from small metal parts like bolts and gears.
The possibilities are endless! Salvaging wind turbine materials creatively diverts useful resources from the waste stream while offering satisfying repurposing challenges for avid DIYers. Just be sure to always prioritize safety and fun.
