While the positive trend in wind energy production is promising for the\u003Cbr \/\u003E\r\nrenewable energy industry, it has also increased the amount of nonbiodegradable\u003Cbr \/\u003E\r\nblade waste. The composite material nature of wind turbine blades\u003Cbr \/\u003E\r\nmakes it difficult to manage at end-of-life due to the lack of implementable\u003Cbr \/\u003E\r\nsolutions that manage Fiber-Reinforced Polymers (FRPs) sustainably and economically, and therefore, most wind blades end up in landfills. \u003C\/em\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cem\u003ERepurposing\u003Cbr \/\u003E\r\nthe material in the wind turbine blades can preserve the highest possible value of\u003Cbr \/\u003E\r\nthe decommissioned blade. While composite recycling technologies exist to\u003Cbr \/\u003E\r\ndifferent degrees, not all are available at scales relevant to the wind energy\u003Cbr \/\u003E\r\nindustry, and there are significant limitations to more widespread industrial\u003Cbr \/\u003E\r\nadoption of these technologies in the United States. Repurposing blades at an\u003Cbr \/\u003E\r\nelement level could enable the highest-value recovery of a final product (i.e.,\u003Cbr \/\u003E\r\nbridges, sound barriers, transmission poles, etc.) rather than molecular\u003Cbr \/\u003E\r\nconstituents\/precursors. The decision process around wind turbine blade end-oflife\u003Cbr \/\u003E\r\npractices requires the identification of supply chain constraints from the\u003Cbr \/\u003E\r\nmoment the blade is deemed to be decommissioned until its final destination or\u003Cbr \/\u003E\r\ndisposal. Stakeholder decision-making, economic impacts, and environmental\u003Cbr \/\u003E\r\nemissions can help navigate the challenges and inform the most suitable end-oflife\u003Cbr \/\u003E\r\napproach for decommissioned wind blades. This work provides the\u003Cbr \/\u003E\r\nstakeholder decision-making for decommissioning wind turbines, and the\u003Cbr \/\u003E\r\nlogistics, environmental impacts, and cost structures of repurposing wind turbine\u003Cbr \/\u003E\r\nblades as high-voltage transmission poles, called the BladePole. This work\u003Cbr \/\u003E\r\nhighlights that component reuse in construction is sufficiently promising to\u003Cbr \/\u003E\r\nmotivate stakeholders to implement structural reuse as part of circularity in\u003Cbr \/\u003E\r\nconstruction materials, leading to reduced waste while reducing greenhouse gas\u003Cbr \/\u003E\r\nemissions. Compared with conventional steel poles and end-of-life wind blade\u003Cbr \/\u003E\r\napplications, BladePole has the lowest overall greenhouse gas emissions and\u003Cbr \/\u003E\r\ncosts. This study quantifies and locates what type of blades will be\u003Cbr \/\u003E\r\ndecommissioned and what new high-voltage transmission lines will be installed\u003Cbr \/\u003E\r\nto improve supply-demand interconnection and provide stakeholders with the\u003Cbr \/\u003E\r\ncommercial path to using decommissioned blades in repurposing applications\u003Cbr \/\u003E\r\nlike the BladePole. This work also presents the importance of quantifying\u003Cbr \/\u003E\r\nmaterial decommissioning not just by weight but also by type, location, quantity,\u003Cbr \/\u003E\r\nand time of decommissioning.\u003C\/em\u003E\u003C\/p\u003E\r\n","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cstrong\u003ECIRCULARITY IN THE BUILT ENVIRONMENT: REVERSE SUPPLY CHAIN\u003Cbr \/\u003E\r\nFOR DECOMMISSIONED WIND TURBINE COMPONENTS IN CIVIL\u003Cbr \/\u003E\r\nINFRASTRUCTURE APPLICATIONS\u003C\/strong\u003E\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"CIRCULARITY IN THE BUILT ENVIRONMENT: REVERSE SUPPLY CHAIN FOR DECOMMISSIONED WIND TURBINE COMPONENTS IN CIVIL INFRASTRUCTURE APPLICATIONS"}],"uid":"27707","created_gmt":"2024-05-13 16:05:06","changed_gmt":"2024-05-13 16:05:40","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2024-05-24T10:00:00-04:00","event_time_end":"2024-05-24T12:00:00-04:00","event_time_end_last":"2024-05-24T12:00:00-04:00","gmt_time_start":"2024-05-24 14:00:00","gmt_time_end":"2024-05-24 16:00:00","gmt_time_end_last":"2024-05-24 16:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Kendeda 210","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
