Circular economy and renewable energy infrastructure such as offshore wind farms are often assumed to be developed in synergy as part of sustainable transitions. Offshore wind is among the preferred technologies for low-carbon energy. Deployment is forecast to accelerate over ten times faster than onshore wind between 2021 and 2025, while the first generation of offshore wind turbines is about to be decommissioned. However, the growing scale of offshore wind brings new sustainability challenges. Many of the challenges are circular economy-related, such as increasing resource exploitation and competition and underdeveloped end-of-use solutions for decommissioned components and materials. However, circular economy is not yet commonly and systematically applied to offshore wind. Circular economy is a whole system approach aiming to make better use of products, components and materials throughout their consecutive lifecycles. The purpose of this study is to enable the integration of a sustainable circular economy into the design, development, operation and end-of-use management of offshore wind infrastructure. This will require a holistic overview of potential circular economy strategies that apply to offshore wind, because focus on no, or a subset of, circular solutions would open the sector to the risk of unintended consequences, such as replacing carbon impacts with water pollution, and short-term private cost savings with long-term bills for taxpayers. This study starts with a systematic review of circular economy and wind literature as a basis for the coproduction of a framework to embed a sustainable circular economy throughout the lifecycle of offshore wind energy infrastructure, resulting in eighteen strategies: design for circular economy, data and information, recertification, dematerialisation, waste prevention, modularisation, maintenance and repair, reuse and repurpose, refurbish and remanufacturing, lifetime extension, repowering, decommissioning, site recovery, disassembly, recycling, energy recovery, landfill and re-mining. An initial baseline review for each strategy is included. The application and transferability of the framework to other energy sectors, such as oil and gas and onshore wind, are discussed. This article concludes with an agenda for research and innovation and actions to take by industry and government.

A broad range of organizations, from small and medium-sized enterprises to large multi-nationals, are interested in adopting circular economy practices. A circular economy can help companies make better use of materials by minimizing the input of natural resources, reducing waste, and optimizing the economic, social, technical and environmental costs and benefits of materials and products throughout their lifecycle. Despite the interest of companies in a circular economy, only 9% of material flows in the global economy are circular. There is formal guidance for those offering business support with the aim to expedite the transition to a circular economy. However, support measures narrowly confine the role of companies and the motivations of business managers to the economic realms, assuming that companies are solely driven by monetary factors. Conversely, pluralist economic views emphasize the broader role of companies in society: for example, in respect of the well-being of their staff and the communities in which they reside. Indeed, our practical experiences of business support have brought alternative motivations to explore a circular economy to the fore. We argue that business support should stem from a broader conception of the role of business in society. The diverse motivations and willingness of business managers to engage in a circular economy should be investigated further with results feeding into broader and more inclusive business support guidelines in the future to accelerate the transition towards a circular economy.
