Advanced Tool Materials and their Influence on the Parameters of CNC Machining of Wood-Based Materials (Part III)
(Mendelova univerzita v Brně, 2024) Rokoský, Petr; Hanincová, Luďka; Procházka, Jiří
This study investigates the effects of tool coatings, cutting speed, and feed per tooth on cutting forces during CNC milling of Medium Density Fiberboard (MDF). CNC milling parameters, specifically cutting speed and feed per tooth, significantly impact tool wear, energy consumption, and surface quality. Coatings can enhance tool performance by reducing friction and heat transfer, thus potentially lowering cutting forces. However, there is limited research on how coatings affect MDF machining. This study examines five coatings, including DLC, TripleSi, Hyperlox, and a lapped surface, to identify optimal combinations for improved machining efficiency. The objective of this research is to systematically evaluate the effects of different tool coatings, cutting speeds, and feed per tooth values on cutting forces during CNC milling of MDF.

Consumer Motivations and Barriers to Re-Use
(Mendelova univerzita v Brně, 2025) Kundrátová, Michaela; Blažeková, Lenka; Kuncová, Gabriela; Chovancová, Silvie; Baláková, Irena
Linear models of production and consumption are unsustainable, as products are often discarded pre maturely and end up in landfills or incinerators (Kircher, 2021). The circular economy offers a framework for reducing waste and improving re source efficiency, with re-use as a key strategy to extend product lifespans and lower environmental impact (Singh & Ordoñez, 2016). Consumers play a vital role in this transition, as their attitudes and behaviours shape material flows and business practices (Lopes et al., 2023). Yet, the post purchase phase-including re-use-remains underex plored (Vidal-Ayuso et al., 2023). Low awareness and sensitivity to greenwashing highlight the need for transparent, educational communication (Lopes et al., 2023). A successful shift to circularity requires not only technical solutions but also cultural and organisational change, driven by active consumer engagement (Fortuna & Diyamandoglu, 2017). This paper aims to identify the motivations and barriers perceived by consumers in relation to the adoption of re-use practices within their consumer behaviour.

ESG Integration Strategies as Green Finance Vehicles in Agri-Food Industry
(Mendelova univerzita v Brně, 2025) Žišková, Veronika
The growing global population and rising living stan dards are driving demand that significantly affects the scope of agricultural production. Permanent grasslands and forests are being converted into arable land, which reduces the soil's ability to sequester carbon and negatively impacts the provision of ecosystem services. There is a high potential for further development of investments in agriculture, where financial returns for investors can be combined with positive social and environmental impacts. Finding a balance between the ongoing changes in Europe, the interests of stakeholders, and broader societal objectives remains a major challenge. In recent years, the European Union has been developing approaches focused precisely on this crucial issue of sustainability as a "green pathway" for companies in the agri-food industry. These transformations, together with the growing interest in investments with positive environmental and social impacts, are fostering the expansion of green finance. Investors can play a key role in addressing global challenges, supporting sustainability, and reducing the negative effects of climate change. Their active engagement in the agricultural and food supply sectors can contribute to a more efficient and sustainable food production system while enabling them to achieve their financial objectives. This study builds upon the theoretical foundations of ESG reporting in EU member states and analyses its current implementation, with particular attention to the new legislative package Omnibus I and its challenges. Special focus is devoted to sectors related to the food supply chain, relevant legislation, and the communication of EU institutions with professional chambers and enterprises obliged to implement ESG reporting.

Food Waste in the Hospitality and Hotel Industry
(Mendelova univerzita v Brně, 2025) Bartlová, Veronika; Májková, Nikola
Food waste is a major global challenge, accounting for nearly one-third of all food produced and contribut ing about 20% of global greenhouse gas emissions (FAO, 2019; Alsuwaidi et al., 2022). The hospitality sector is a significant contributor, with much of its waste avoidable, driven by guest behaviours, cultural tendencies, and operational inefficiencies such as overproduction and buffet concepts (Dolnicar et al., 2020; Okumus et al., 2020). In Czechia, despite growing awareness of sustainability, environ mental measures in hotels and restaurants remain limited, highlighting a gap in achieving Sustainable Development Goal 12 (Scholz et al., 2024; United Nations, 2015). Effective strategies exist from nudges and education to food redistribution, but practical implementation is often hindered by managerial and structural barriers (Chawla et al., 2020; Reynolds et al., 2020). This study examines both accommodation providers' practices and customers' perceptions of sustainable gastronomy to identify drivers, barriers, and motivators for reducing food waste.

Setting Subsidy Conditions to Support Sustainable Investments in Transport
(Mendelova univerzita v Brně, 2025) Žapka, Martin; Poláchová, Marie
The transport sector is a significant polluter of the environment. One of the tools supporting the achievement of climate neutrality is subsidies (including support for sustainable transport). The conditions of subsidies in transport do not focus only on the economic value of the investment but also include the social and environmental aspects of the investment. Policymakers at various levels are asking themselves how to set up evaluation frameworks, criteria and what methods to use to assess the sustainability of investments. Efforts are underway within the EU to harmonise these criteria and methods, including for projects (co-)financed from EU funds. Reporting (use) of some criteria and methods is mandatory for the disbursement of EU funds; some remain at the level of recommendations. It is up to each EU country to decide with what degree of bindingness it will require the given criteria and methods. One of the indicators of the success of countries in the field of sustainability are the so-called ESG indices (ESG scores). The Risk Watch Initiative ESG Index [1] was used to assess the relationship between the level of mandatory subsidy requirements and the level of sustainability of individual countries. Efforts to assess the sustainability of transport at the national level can also be found [2].
