In order to approach a system change towards a circular economy model (CE) in Europe, the entrepreneurial activities of young people need to be encouraged to achieve the Green Deal (GD) goals. This article presents the evaluation results of young people’s awareness and attitudes towards the CE and the GD. The data used in this study was collected by surveying 286 young people from five European countries. The questionnaire covered four areas: (1) belief, (2) knowledge, (3) competence, and (4) young people’s ability to deal with the CE. Descriptive and exploratory factor analysis (EFA) was conducted to analyse the questionnaire on the basic factors that motivate young people to the CE and GD. A literature review was conducted to identify the main research concepts and connections. A review included two phases, the first encompassing a search through the Web of Science (WoS) Core Collection for research papers meaningful for further research, followed by Leximancer analysis. The analysis showed that young people believe in the principles and priorities of CE but do not receive enough support to participate and implement the priorities actively. Formal education does not provide enough knowledge to work in this field actively. They are primarily undecided about their understanding of the principles of CE. Responses to whether they can implement the project, business, or entrepreneurial ideas are also uninspiring. Young people do not see themselves as creators of change towards the CE. However, it is encouraging that they approach the CE from different angles and show responsible behaviour in everyday life. Young people’s ability to reason, think, evaluate, connect, and create new solutions for the CE is not enviable. Most respondents did not comment on their competence in concepts of the GD and CE. It is encouraging to know that they have already heard about the CE’s goals and action plan. Young people do not show significant skills in the practical implementation of CE principles. The analysis has shown that young people are particularly unable to reason, think, and evaluate in an entrepreneurial way when linking the CE to business opportunities. Relating them to business models and entrepreneurship also seems to be problematic. As a result, the majority of them are unable to design, develop, and create new business solutions.

This paper introduces a conceptual model for evaluating seaports’ acceleration towards the circular economy. The model is based on the identification and definition of circular economy indicators, weighted according to the 9 R-strategy transitions towards the circular economy. We have employed the analytical hierarchy process for weight detection and further calculations of the final seaport circularity value. Our results suggest conceptual validity and provide a detailed insight into the circular activities of the seaports from the indicators, as well as 9 Rs and sustainability perspectives.

When considering the sustainability of production processes, research studies usually emphasise environmental impacts and do not adequately address economic and social impacts. Toy production is no exception when it comes to assessing sustainability. Previous research on toys has focused solely on assessing environmental aspects and neglected social and economic aspects. This paper presents a sustainability assessment of a toy using environmental life cycle assessment, life cycle costing, and social life cycle assessment. We conducted an inventory analysis and sustainability impact assessment of the toy to identify the hotspots of the system. The main environmental impacts are eutrophication, followed by terrestrial eco-toxicity, acidification, and global warming. The life cycle costing approach examined the economic aspect of the proposed design options for toys, while the social assessment of the alternative designs revealed social impacts along the product life cycle. In addition, different options based on the principles of the circular economy were analysed and proposed in terms of substitution of materials and shortening of transport distances for the toy studied.

This review provides a comprehensive Life Cycle Assessment (LCA) of a cosmetic cream to assess the environmental impacts throughout its entire life cycle, from raw material extraction to disposal, using the methodology according to international standards. The LCA was performed using the OpenLCA 2.0.1 software, with data from the Ecoinvent 3.8 database and relevant literature. The assessment focused on multiple impact categories, including climate change, acidification, eutrophication (freshwater, marine and terrestrial), ecotoxicity (freshwater), human toxicity (cancer and non-cancer), ionizing radiation, land use, ozone depletion, photochemical ozone formation, resource use (fossils, minerals and metals), and water use. The LCA of a cosmetic cream containing gold nanoparticles revealed significant environmental impacts across critical categories. The total climate change potential was 2596.95 kg CO₂ eq., driven primarily by nanoparticle synthesis (60.7%) and electricity use (31.9%). Eutrophication of freshwater had the highest normalized result (3.000), with nanoparticle synthesis contributing heavily, indicating the need for improved wastewater treatment. The resource use (minerals and metals) scored 1.856, while the freshwater ecotoxicity reached 80,317.23 CTUe, both driven by the nanoparticle production. The human toxicity potentials were 1.39 × 10⁻⁶ CTUh (cancer) and 7.45 × 10⁻⁵ CTUh (non-cancer), linked to emissions from synthesis and energy use. The LCA of the cosmetic cream revealed several critical areas of environmental impact. The most significant impacts are associated with gold nanoparticle synthesis and electricity use. Addressing these impacts through optimized synthesis processes, improved energy efficiency, and alternative materials can enhance the product’s sustainability profile significantly.
