The purpose of this paper is to analyze recent publications in scientific journals on the circular economy and energy through a systematic review using the PRISMA method and to propose a framework. In recent years, the circular economy has been widely recognized as a viable solution to address environmental and economic challenges. The transition to renewable sources, such as solar, wind, and biomass, is essential for a clean and balanced energy market. The methodology adopted was a systematic review of the scientific literature using the PRISMA method, which aims to categorize published research, evaluating it in terms of its objectives, methodologies, results, and conclusions. To this end, full articles published in scientific journals between 2021 and 2025 on the subject were identified. The analysis of the selected studies reveals an intrinsic relationship between the circular economy and sustainable energy, particularly in the context of Sustainable Development Goals (SDGs) 7 and 12. The results highlight that circular economy practices, such as waste recovery, bioenergy generation, and gasification, not only demonstrate their ability to create sustainable value chains but also contribute to reducing environmental impacts, promoting energy efficiency, and present a proposed framework for analysis and proposition.

In the current context of the complexity of municipal management, the sustainable development of communities and compliance with the “2030 Agenda” objectives are essential. These objectives aim to reduce the negative environmental impact of cities by the year 2030, with special attention to issues such as air quality and municipal waste management, among other UN actions. The main objective is to verify the impacts on the residents around the São João monument, located in a city in the interior of Brazil, with its installation following the principles of sustainable development, Agenda 2030, and SDG 8. It is relevant to verify, with the rural community, the positive and negative impacts on the quality of life and development of families who reside around the São João monument. The research method was a single case study, and the data collection techniques were qualitative. Finally, the results point to benefits for the community with the implementation of the São João monument, such as the generation of income and jobs, the development of tourism, and compliance with SDG 8, goal 8.9. However, improvements in local planning and development are still needed.

The transition towards circular and sustainable business models in the construction sector has become a central priority for European policy and industry practice. Buildings generate significant environmental impacts throughout their life cycle, and shifting from linear approaches to regenerative models is essential for improving resource efficiency, reducing waste, and extending the useful life of existing structures. This study examines how circular business logic can be meaningfully integrated into the construction and reconstruction of buildings, emphasising the strategic, organisational, and financial conditions that enable the adoption of circular principles. The analysis highlights the interdependence between design for adaptability, digital traceability of materials, collaborative value chains, and innovative revenue mechanisms capable of supporting long-term sustainability. It also underscores the importance of regulatory stability and organisational learning for the practical implementation of circularity in buildings. The study contributes to the academic debate by proposing an integrated conceptual framework and by identifying priorities for policy, management, and future research.
