“…The pulverizing aerator, for discharging harmful gases of anaerobic decomposition of organic matter contained in bottom sediments, such as hydrogen sulfide, methane and ammonia, and for the simultaneous oxygenation of hypolimnion waters, uses only wind energy [10,20]. This is the cleanest energy available on Earth [29,30]. This type of aerator maintains moderate oxygenation in the bottom area in the range of 0-1 mg O 2 •dm −3 [21].…”

In the introduction to this paper, the characteristics of Góreckie lake and the construction and operation of the wind-driven pulverizing aerator are presented. The purpose of this manuscript is to determine the efficiency of the pulverizing aerator unit in the windy conditions of Góreckie Lake. The efficiency of the pulverization aerator depends on the wind conditions at the lake. It was necessary to conduct thorough research to determine the efficiency of water flow through the pulverization segment (water pump). It was necessary to determine the rotational speed of the paddle wheel, which depended on the average wind speed. Throughout the research period, measurements of hourly average wind speed were carried out. It was possible to determine the efficiency of the machine by developing a dedicated mathematical model. The latest method was used in the research, consisting of determining the theoretical volumetric flow rates of water in the pulverizing aerator unit, based on average hourly wind speeds. Pulverization efficiency under the conditions of Góreckie Lake was determined based on 6600 average wind speeds for spring, summer and autumn, 2018. Based on the model, the theoretical efficiency of the machine was calculated, which, under the conditions of Góreckie Lake, amounted to 75,000 m3 per year.

“…About a third of the 66 titles broadly discuss: the role of wind and other renewable energy technologies to power a sustainable and circular economy [57,58,[67][68][69][70][71][72][73][74][75][76][77], or battery storage (e.g., [72,78]) and the potential for integration with a hydrogen economy to avoid a loss of generated wind power (e.g., [79]), using hydrogen subsequently in methanol production [80][81][82]. Schoden et al [83] present a project to raise public awareness about the need for a circular economy for wind turbines.…”

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.

“…Esta concienciación debe empezar en los primeros niveles, y en especial en Educación Infantil por su carácter globalizador del aprendizaje. En este sentido, ya existen diversas investigaciones que apuntan claramente a cómo ayudar a trabajar el reciclaje en el aula, creando una conciencia inicial en los ciudadanos que, en su mayoría, no han tenido experiencias externas similares, y que deberán lidiar con los efectos en un futuro a largo plazo virando hacia un modelo de EC (Buil, Roger-Loppacher y Tintoré, 2019;Boyd, 2020;Schoden et al, 2020).…”

Resumen: Ante el conflicto que plantea el calentamiento global y la sobreexplotación de los recursos materiales, la necesidad de plantear nuevas alternativas en el modelo de producción de cara a un futuro más sostenible se hace cada día más imprescindible. Esto hace indispensable que existan estrategias de educación ambiental efectivas para desarrollar, tanto en las generaciones presentes como en las futuras, un sentido de cuidado y respeto para el entorno. El presente trabajo tiene como objetivo general medir el grado de concienciación y sensibilización de docentes y alumnos de Educación Infantil y Primaria en torno a la Economía Circular (EC), de manera transversal a través de diferentes herramientas. La metodología utilizada se encuentra bajo el paradigma mixto cuantitativocualitativo; cuantitativa mediante el uso del cuestionario y cualitativa a través de la observación participante y el registro de observación. De los resultados se infiere un interés mayoritario por los problemas medioambientales, si bien el conocimiento de ciertos términos, como alfabetización ecosocial, es escaso, entre los docentes. Además, se ha demostrado que la educación ambiental resulta motivadora para los alumnos, ya que se refuerza el sentido del aula como conjunto.
