This paper explores the implementation of the circular economy in the energy sector. The research findings contribute to our understanding of the practical application of the circular economy, enabling policymakers and stakeholders to make informed decisions and develop targeted strategies. The study analyzes 88 Portuguese companies’ reports, examining the presence of circular economy strategies and initiatives. The results reveal that energy sector companies tend to prioritize reporting their greenhouse gas reduction efforts over their circular economy strategies. The findings align with previous studies in the oil and gas industry, emphasizing the significance of sustainability reporting and potential biases in reporting practices. The study also identifies a gap between circular economy terminology and its representation in reports, indicating the need for greater incorporation of circular economy-oriented initiatives in the energy sector. The research highlights the role of technology in fostering innovation and calls for strategic alliances and knowledge sharing to drive circular economy practices. Further research is recommended to understand the barriers to implementing circular economy practices and identify effective solutions. Overall, this paper provides valuable insights for advancing the circular economy in the energy sector and achieving broader sustainability goals.

Students and employers, are the “clients” of Higher Education Institutions (HEI), so it is important to obtain their feedback on the quality of HEI and the courses they attend. This article aims to listen to students’ opinion as “clients” of higher education, based on their expectations and perceptions, to measure the quality of the service of HEI. The results from empirical research were presented on the measurement of expectations and perceptions to assess the quality of services provided by a HEI perceived by students, based on observations obtained through survey. Quantitative methodology and data analysis techniques were applied. The SERVQUAL questionnaire was filled by 271 students who attended the 1^st, 2^nd and 3^rd year of the five undergraduate courses taught by the institution, in the academic year 2021/2022. The values obtained for the expectations were very high which translated into negative deviations (Gaps). Thus, we can conclude that ESCE students are very demanding, have high expectations or are very demanding when they classify perceptions by assigning them low values.

The purpose of this chapter is to present a set of proposals for the creation and promotion of an infrastructure network to support entrepreneurship in Angola. In this sense, the authors developed an analysis and research work, framed with Activity 9 of the ENVOLVER project, a project within the scope of the Production Support, Export Diversification, and Import Substitution Program (PRODESI) of the Government of Angola, led by National Institute for Support to Micro, Small, and Medium Enterprises (INAPEM) and financially supported by the European Union, that aims to promote the development of a private sector, more sustainable and more inclusive, based on the diversification and provision of financial services adapted to micro, small, and medium enterprises (MSMEs) and entrepreneurs in Angola.
