“…The life cycle environmental impacts of one kWh of electricity produced by 3.6 MW and 4.8 MW onshore wind turbines operating in Turkey are compared in Figure 5. As expected, the unwanted environmental impacts are reduced by around 63,67,65,64,63,66,63,63,70,69, and 63% for ADP, ADP fossil, AP, EP, FAETP, GWP, HTP, MAETP, ODP, POCP, and TETP, namely when 4.8 MW onshore wind turbines are used instead of 3.6 MW ones.…”

This study aims to evaluate in detail the environmental impacts of the turbines used for electricity generation by wind energy, from a life cycle perspective. For this purpose, a comprehensive literature review is conducted and the life cycle environmental impacts of two sizes of wind turbines, namely 3.6 and 4.8 MW, in Turkey are analyzed. Sustainability studies, especially life cycle assessment (LCA) findings, yield healthy results only if the data used are site-specific. The system has been modeled using GaBi software and the Ecoinvent database. The functional unit is defined as 1 kWh of generated electricity. The impacts have been estimated using the CML 2 Baseline 2001 method. The 4.8 MW turbine has lower environmental impacts than the other turbine. The construction of wind turbines has the greatest share of the environmental impacts of all the options considered. Recycling materials at the end of plant life can reduce unwanted environmental impacts by up to 49%. Similar studies based on site-specific data will help to inform electricity producers and policymakers about wind energy’s current impacts and environmental hotspots. Conducting analogous studies is critical to reducing the environmental impacts of wind energy, which will play an important part in the future of the energy sector.

“…Through an investigation of Sweden's wind power sector until 2050, the study underscores the vital role of circular approaches and the reduction of carbon-intensive material production in meeting emission goals and establishing closed material cycles within the realm of renewable energy infrastructure. Gennitsaris et al [69] introduced a novel integration of LCA and Data Envelopment Analysis (DEA) for assessing diverse end-of-life strategies for decommissioning wind turbines in a circular economy context. Through scenarios focused on a representative wind turbine type, including options like mechanical recycling, landfill disposal, and advanced thermal recycling methods, the study not only evaluates their effectiveness but also suggests circular economy-based policy scenarios to enhance sustainable waste management.…”

The circular economy (CE) has recently emerged as a key strategy for promoting sustainability and reducing waste in various industrial sectors. This paper provides an overview of the definition, assessment and enhancement of circularity in general and in five key industries, including aerospace, wind energy, transportation, automotive and sports goods, by using data and information from the literature and for the section of the definitions of the CE also using information from the EC funded project “RECREATE”. The survey reviews in detail the different definitions, assessment methods and metrics used to explore and evaluate circularity, including assessment frameworks such as Life Cycle Assessment (LCA) and assessment indicators. Furthermore, it explores the challenges, possibilities and available tools for enhancing circularity, focusing on digital tools. The survey highlights the importance of a holistic and systemic approach to circularity concerning all stakeholders along the value chain. Overall, this study aims to contribute to a better understanding of the circular economy's definition, assessment, and enhancement and provides insights for future research.
