Key Findings
- 01Approximately 50-60% of decommissioned onshore wind turbines in Denmark and Germany are exported, primarily to other European countries.
- 02Current forecasting models for blade recycling capacity may overestimate potential quantities due to static decommissioning time assumptions and neglect of second lifecycles.
- 03Germany's large wind turbine fleet suggests it can reach the volume threshold for economically viable blade-recycling facilities, while Denmark's recycling efforts may require aggregation of resources from other sources or industries.
Application
Design takeaway
When designing for circularity, especially for large-scale infrastructure like wind turbines, anticipate and plan for the logistical realities of material export and the varying economic viability of recycling across different regions.
How to apply
When assessing the feasibility of recycling initiatives for large products, gather empirical data on current end-of-life pathways (e.g., export, reuse) and use this to inform material flow forecasts and infrastructure planning.
Project actions
- 01When researching a product's lifecycle, investigate where components and materials actually go at the end of their life, not just where they *could* go.
- 02Consider the economic and logistical factors that influence material recovery and recycling pathways.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilizes empirical data from mature markets.
- +Develops a novel forecasting model that accounts for second lifecycles.
Limitations
The study's findings are specific to Denmark and Germany; results might differ in other regions. Future trends in reuse and recycling policies could alter these pathways.
Reliability & validity
Reliability is supported by empirical data collection. Validity is enhanced by the development of a new forecasting model that addresses limitations of previous approaches. However, the predictive validity of the model for future scenarios relies on assumptions about future practices.
Think critically
How do the economic incentives for exporting end-of-life components influence the development of domestic circular economy infrastructure?
Design Principles
"Design for End-of-Life Realities: Account for actual material and component flow patterns, including export and reuse, when planning for circular economy infrastructure and resource recovery."
Understanding the actual material and component flows from end-of-life products is critical for developing effective circular economy strategies. This research provides empirical data that challenges existing assumptions, enabling more realistic planning for resource recovery and waste management in the renewable energy sector.
What This Means for Your Design
Lots of old wind turbine parts are sent to other countries instead of being recycled locally. This means we need to be more realistic about how much material we can actually recycle at home and plan accordingly.
How to use in your project
- 1.Use the findings to justify the importance of investigating actual end-of-life pathways for your chosen product.
- 2.Incorporate the concept of material export and its impact on local recycling capacity into your analysis of a product's sustainability.

Paragraph starter
This research highlights that the actual end-of-life pathways for products, such as the significant export of decommissioned wind turbines, must be empirically investigated to accurately forecast material flows for recycling. Ignoring these real-world logistics can lead to overestimations of domestic recycling capacity, impacting the feasibility of circular economy initiatives.
