An innovative approach to organizational changes for sustainable processes : a case study on waste minimization
Eva Krhač Andrašec, Tomaž Kern, Benjamin Urh, 2023, original scientific article

Abstract: It is necessary to adapt constantly to the business environment with its changing demands. Understanding the objectives, scope, and limitations of actual process changes is crucial, and can be achieved with numerous measures, methods, and techniques. This research demonstrates an innovative approach to organizational changes to enable sustainable processes. In the first part of this research, relevant measures, methods, and techniques are selected through an in-depth literature review. Then, an international online questionnaire is executed among 213 enterprises from four countries. In the last part of this research, the developed approach is tested for the example of waste minimization in the process of developing coatings. Based on the analysis of the survey questionnaire, the usability and benefits of various measures are demonstrated, namely from the point of view of their positive impact on structural and operational efficiency indicators. At the end of the article, a case study presents the success of the innovative approach in terms of 88% waste minimization and up to 48% time and cost reductions in the process of developing coatings. The proposed approach enables better choices to be made and the more efficient use of various measures, which can lead to more sustainable processes and improve the efficiency of enterprises.
Keywords: organizational changes, key performance indicators, measures, methods and techniques, sustainable processes, waste minimization

6th International Conference on Technologies & Business Models for Circular Economy : conference proceedings
2024, proceedings

Abstract: The 6th International Conference on Technologies & Business Models for Circular Economy (TBMCE) was organized by the Faculty of Chemistry and Chemical Engineering of the University of Maribor in cooperation with Strategic Research and Innovation Partnership – Networks for the transition into circular economy (SRIP – Circular economy), managed by the Chamber of Commerce and Industry of the Štajerska. The conference was held in Portorož, Slovenia, at the Grand Hotel Bernardin from September 6th to September 8th, 2023. TBMCE 2023 was devoted to presentations of circular economy concepts, technologies and methodologies that contribute to the shift of business entities and society as a whole to a more responsible, circular management of resources. The conference program included a round table Standardization for circular economy – more secure and less complicated closing of material loops, 6 panel discussions, 1 plenary and 3 keynote lectures, oral and poster presentations. The event was under the patronage of Ministry of the Economy, Tourism and Sport and Ministry of Cohesion and Regional Development. The Netherlands joined us as a partner country.
Keywords: sircular economy, sustainable development, processes and technologies, circular business models, research and development

Managing document management systems’ life cycle in relation to an organization’s maturity for digital transformation
Simona Sternad Zabukovšek, Sandra Jordan, Samo Bobek, 2023, original scientific article

Abstract: Document management systems (DMS) have become an important topic regarding digital transformation in organizations because they enable paperless business, speed up processes, lower business costs, and support sustainability activities in organizations. DMSs should be considered as green technology and also as technology crucial for green digital transformation. Sustainability is becoming increasingly crucial for organizations and society, and DMSs, along with paperless business, can contribute to the sustainable orientation of organizations. However, the problem with DMS implementations is that they often fail and that DMS users often use DMSs at a basic level, which means that, among other things, they still prefer to print documents rather than use electronic documents. A framework that can contribute to a better implementation and a higher level of use of DMSs, which both lead to a more green digital transformation of the organization, represents an organization's maturity. We used the Process and Enterprise Maturity Model (PEMM) to assess the organization's maturity level concerning the DMS' life cycle. Findings are presented from the research study. The research study was based on a questionnaire and collected data from DMS users. The research study showed that an organization's maturity impacts the DMS' life cycle. Organizations that manage the DMS' life cycle will better cope with digital transformation and sustainability issues related to paperless business.
Keywords: digitalization of processes, document management system (DMS), organization maturity, process maturity, life cycle, digital transformation

Development of an experimental Dead-End microfiltration layout and process repeatability analysis
Gorazd Bombek, Luka Kevorkijan, Grega Hrovat, Drago Kuzman, Aleks Kapun, Jure Ravnik, Matjaž Hriberšek, Aleš Hribernik, 2024, original scientific article

Abstract: Microfiltration is an important process in the pharmaceutical industry. Filter selection and validation is a time-consuming and expensive process. Quality by design approach is important for product safety. The article covers the instrumentalization and process control of a laboratory-scale dead-end microfiltration layout. The layout is a downscale model of the actual production line, and the goal is filter validation and analysis of process parameters, which may influence filter operation. Filter size, fluid pressure, valve plunger speed, and timing issues were considered. The focus is on the identification of the most influential process parameters and their influence on the repeatability of pressure oscillations caused by valve opening. The goal was to find the worst-case scenario regarding pressure oscillations and, consequently, filter energy intake. The layout was designed as compact as possible to reduce pressure losses between the filter and valve. Valve-induced pressure oscillations proved to be prevailing over the water hammer effect. Several filters in sizes between 3.5 cm2 and 6900 cm2 were tested, and some recommendations were suggested for the reduction of energy intake of the filter and to improve the repeatability of the process.
Keywords: filtration, pressure oscillations, repeatability, processes, parameters

Enhancing the performance of high-growth small- and medium-sized enterprises through effective project- management processes and stakeholder engagement : a systems perspective
Igor Vrečko, Polona Tominc, Karin Širec, 2023, original scientific article

Abstract: This study examines the impact of project management practices on high-growth Small and Medium-sized Enterprises (HG SMEs) from a systems perspective, utilizing Structural Equation Modelling (SEM) and data from a diverse SME sample. It investigates the intricate relationships among project management system support, project management processes, stakeholder involvement, project management success, project success, and HG SME growth. Our findings highlight the substantial positive influence of project management processes and stakeholder engagement on project management success. These factors subsequently contribute significantly to both project success and the overall growth of HG SMEs. Notably, project management system support does not exhibit a substantial influence on these success factors. Furthermore, our research uncovers important indirect effects. Project management processes indirectly impact both project success and HG SME growth, underscoring their central role. Similarly, stakeholder involvement indirectly influences HG SME growth through its impact on project success, emphasizing its significance. This study contributes to the existing body of knowledge by emphasizing the critical roles of project management processes, stakeholder engagement, and project success as drivers of SME growth. These insights have valuable implications for SME managers, project leaders, and policymakers, highlighting the essential nature of effective project management in shaping the growth trajectory of SMEs.
Keywords: project management, project success, SME growth, stakeholder engagement, projectmanagement processes, high-growth SMEs, systems perspective, SEM
