This bibliometric study investigates the scientific landscape of environmental sustainability within the European Green Deal (EGD) framework. Utilizing data from the Scopus and Science Direct databases, the study aims to map research trends and frontiers, providing a comprehensive overview of the evolving discourse on sustainability. The EGD’s ambitious goal to render the European Union climate-neutral by 2050 is highlighted, showcasing its significant impact across multiple sectors. The study reveals the integration of new methods and broadening research scopes by employing modern bibliometric techniques. Key thematic focuses include the transition to a circular economy and the emphasis on sustainable resource management, underpinning the EGD’s comprehensive approach to combining economic growth with environmental protection. The analysis unveils the critical role of technological innovation and policy reforms in advancing toward a sustainable, competitive, and climate-neutral economy. The research demonstrates the pivotal role of empirical studies in guiding policy formulation and implementation, showing how targeted measures in resource and energy productivity, combined with a decisive shift towards renewable energy, are integral to fostering a sustainable, competitive, and climate-neutral economy. This convergence of findings reinforces the argument that a multifaceted approach, encompassing policy, technology, and innovation, is essential for navigating the challenges of environmental sustainability and climate change, aligning closely with the overarching aims of the EGD.

“…A circular economy, which includes the creation of closed water cycles, is one of the key components of the European Union's sustainable development strategy and policy [1]. Due to ongoing climate change and water shortages, the need to harvest rainwater has been increasingly brought to public attention in the 21st century [2].…”

“…The advantages of rainwater collection systems have been discussed in detail by Morey et al [24], Yawalkar et al [25], and Ertop et al [26]. Those authors have noted that rainwater can be utilised (1) as an additional source of water where demand is high but water from other sources is scarce, (2) to protect water resources, (3) to reduce the consumption of surface and groundwater resources, (4) to produce safe drinking water in the process of purification, (5) for watering plants and landscaping, and (6) to reduce unproductive outflow of water through rivers into the seas and oceans; at the same time, rainwater utilisation systems are (6) simple, easy to maintain, and cheap to operate, (8) can be used anywhere, regardless of the terrain, geology, or land development pattern, (9) can be used on-site in households or public utility facilities, (10) can improve the water management system, and (11) can protect urban areas from flooding and reduce the severity of floods during heavy rainfall. It has also been demonstrated that excess rainwater can be diverted and captured for groundwater recharge.…”

The aim of this paper was to determine the efficiency of a rainwater treatment installation located near the farm buildings of Roztocze National Park (RNP), Poland. The rainwater treatment system, consisting of two polypropylene filters, one activated carbon filter and a UV lamp, was examined. Samples of raw and treated rainwater were collected once a month from June to December 2023. The study shows that average efficiency of pollutant removal in the analysed rainwater treatment system was not very high and amounted to 38.8% for ammonia, 29.6% for turbidity, 27.9% for NO2, 19.8% for NO3, and 6.9% for copper. The low efficiency values can be explained by the low concentration of these parameters in rainwater from the tanks. The efficiency of removing microbiological contaminants was very high and ranged from approximately 98% to 100%. It was shown that the UV lamp ensures very good disinfection of rainwater. The study shows that rainwater treated using filtration and disinfection (UV lamp) can be used for watering the Polish Konik horses living in the park, as well as for washing vehicles, watering green areas, or flushing toilets. The present findings can be used in the design of a new system for managing rainwater that is planned to be built in the RNP’s Animal Breeding Centre, as well as to prepare other rainwater systems, especially in protected areas.
