DQ7 Precision Cutting for Renewable Energy Recycling

Wind turbine blades present a unique cutting challenge. Constructed from durable composite materials such as fiberglass and wood, they are extremely difficult to section using conventional methods.

Key challenges included:

– The sheer size and strength of turbine blades
– Difficult composite structures that resist standard cutting techniques
– Environmental concerns such as dust, mist, and noise
– The need to create a safe, enclosed cutting process suitable for an industrial recycling environment

With experience using diamond wire in concrete cutting environments, the contractor engaged Diaquip for this new recycling application. The project utilized the DQ7 Diamond Wire, selected for its durability and ability to adapt beyond traditional applications.

To meet the blade-cutting requirements, the team engineered a custom setup:

– A cutting system based on a hydraulic machine platform
– Wire running speeds of approximately 25 m/s
– A conveyor-fed blade positioning system for controlled sectioning
– A fully enclosed cutting environment to isolate hazards
– Remote operation through a viewing window for improved safety

Although the project is still in its early stages, the DQ7 wire has already proven effective.

Results so far include:

– Around 12 blades successfully processed during the initial phase
– Continuous improvements made through ongoing R&D and environmental testing
– Reliable cutting performance across difficult composite materials
– A safer process achieved through full enclosure and remote operation

With more wind farms reaching end-of-life and disposal regulations tightening, blade recycling is expected to scale rapidly over the coming years. This cutting method has strong potential to be applied to other large composite structures that cannot be processed through conventional shredding systems.

The contractor and Diaquip are continuing to develop the process, positioning the solution as a key enabler in renewable energy recycling infrastructure.

– Diamond wire solutions can extend far beyond concrete cutting into advanced composite recycling
– Collaborative engineering ensures safer, tailored cutting systems
– DQ7 Diamond Wire delivers reliable performance in demanding renewable energy applications
– Wind turbine blade recycling will become a major global requirement over the next decade
