Circular Economy (CE) practices and technologies are essential for increasing sustainability performance in manufacturing. Due to the increasing number of environmental regulations and growing public awareness of environmental issues, especially in the EU, CE is increasingly seen as a valuable factor in improving competitiveness. Therefore, there is a need for a fuller understanding of the ways in which CE technologies can be implemented into the manufacturing industries. The aim of this paper is to contribute to the identification of the characteristics of manufacturing companies and their perceptions of the barriers to the adoption of CE technologies. This survey-based study of 241 manufacturing companies (comprising a sub-sample of Slovak and Slovenian companies from the more extensive European Manufacturing Survey) uses a series of statistical tests to examine the implementation of three CE technologies. The results show that there is significant relationship between the adoption of CE technologies in manufacturing companies and their size, location, R&D activities, company age and product batch size. Finally, the research reveals the surprising finding that there is no apparent link between the perception of CE barriers and the plans of companies to implement selected CE technologies.

Industry 4.0 technologies’ adoption became a reality in manufacturing and other industrial companies. The effects of this adoption on several areas including the Circular Economy are interesting in the research field. Deep research and investigation of various Industry 4.0 technologies’ relationships with the Circular Economy are presented in this article. The investigation is based on collected data from 798 companies in five countries, Lithuania, Slovakia, Austria, Croatia, and Slovenia as part of the European Manufacturing Survey project in 2018. After filtering the data, groups’ comparison is used to form potential prospective relationships in connection with the presented literature. A logistics regression test is used by SPSS software to validate the hypotheses and potential relations. Based on the achieved results, it seems that both Industry 4.0 and non-Industry 4.0 technologies can have significant relations with Circular Economy technologies, so they can be potentially influenced or enhanced by both. Similarly, an investigation of the relations between the development of products with improved environmental impact and the use of Industry 4.0 technologies showed no clear dominance of Industry 4.0 technologies over non-Industry 4.0. Finally, there are two of the twelve investigated technologies that have a significant relationship (potential impact) on both the Circular Economy technologies and product development with improved environmental impact.

The diffusion of technologies within an economic system is an intricate process, influenced by a variety of factors, including governmental policies, the characteristics of adopting companies, and the technologies that can be adopted. This study aimed to investigate the relationship between the implementation of environmental management systems (EMSs), such as ISO 14001, or energy management systems (EnMSs), such as ISO 50001, and the adoption of energy recuperation technologies (ERTs), which are a subset of energy efficient technologies (EETs). To achieve this, our research leveraged data from the 2018 European Manufacturing Survey, specifically a subsample of 798 companies across five European countries: Croatia, Slovenia, Austria, Slovakia, and Lithuania. Due to the investigation of relationships and the type of variables used, we employed a two-step ordinary least squares (OLS) regression analysis. Our analysis uncovered that the current utilization of EMSs and EnMSs within companies is significantly linked to the current use of ERTs. However, upon further examination of the implementation timeline, it became improbable that EMSs or EnMSs have a substantial impact on enhancing the adoption of these technologies in the short term. Moreover, our results show that technological intensity and product complexity does not play a determining role in the adoption of ERTs, but they did show that larger companies tend to invest more in ERTs, which is in line with the findings of previous studies.

Purpose: This study investigates the awareness and understanding of eco-labels among Slovak consumers, alongside their willingness to pay a premium for environmentally friendly products. Methodology/Approach: For this study, a custom questionnaire was designed. The survey was conducted online using Google Forms from December 2020 to the end of February 2021, The collected data were analyzed using descriptive statistics and the Mann-Whitney U test to test differences among respondent groups. Findings: Results reveal that only a minority of respondents correctly understand the meaning of the analyzed eco-labels, with higher awareness for labels associated with direct economic benefits, such as energy savings. Statistical analysis highlights significant differences in awareness and willingness to pay based on age and income. Most respondents express a preference for receiving eco-label information through in-store displays and banners. Research Limitation/Implication: Sample is restricted to limited size and structure that was reachable during COVID-19 pandemic. Originality/Value of paper: There are few studies that examine eco-labeling of products in relation to demographic data of respondents, but to our knowledge none from Slovakia. In addition, this study uniquely includes identifying respondents' preferences when obtaining information about eco-labels on products.
