The role of green competencies for the sustainability manufacturing grow: preliminary research

100%

Graczyk-Kucharska M.

2022

tom z. 159

105--117

Purpose: The EU’s guidelines exert an important influence on companies aiming to accelerate the implementation of green measures and minimise their negative environmental impacts. The objective of this paper is to define the key categories of green organisations and green competences whose development can accelerate the implementation of green processes in companies. Design/methodology/approach: Based on the literature review, a semi-structured qualitative research questionnaire was developed and a pilot study was conducted on four large manufacturing companies. Findings: A list of categories of activities linked to green organisations was developed and key components of green competences were defined. It was shown that performance-related managerial competences are the most important components of green competences for the companies. It was also pointed out that the categories that are the components of green 19 organisations are important and that the degree to which they are met has been increasing over time in recent years. Research limitations/implications: The pilot study was conducted with middle and senior 22 level representatives of four manufacturing companies. Its conclusions will be used to continue the research with a larger sample. Practical implications: The results of the study will allow companies to better adapt to the challenges of sustainability and green organisations. Key green competences and an emphasis on their development in the companies will allow more green organisation areas to be achieved more quickly. Social implications: The development of green organisations has a direct influence on minimising the negative environmental impacts and thereby improving the quality of life for everyone in society. Originality/value: Based on the analysis of the literature, it can be stated that there is no clear definition of green organisations while the variety of measures and their nomenclature in the area of sustainability is extensive. Research in that area contributes to the development of the science of management and quality and represents an important new field of research. This paper is meant for researchers and practitioners as well as HR representatives who work with the issue of green competences and green organisations.

Achievements of sustainable manufacturing by machining

Kopac J.

Purpose: Manufacturing industry is under increasing pressure of global competition, stricter environmental legislation and supply-chain demand for improved sustainability performance. The latter can be achieved through changes in products, processes and systems which are related to the sustainability issues. Sustainability in manufacturing is an appropriate approach; however it is still unified to a higher production rate and benefit. To encounter this problem academic, scientific, cultural and human organizations have to find the way, on a highest level of decision; maybe to rise the sustainability over production growth. This paper also presents some results from modelling and optimization of sustainable machining of Inconel 718. High temperature alloys, such as Nickel and Titanium alloys, pose significant difficulty in machining, due to their unique thermo-mechanical properties. Design/methodology/approach: In the paper are presented and evaluated two sustainable machining alternatives: cryogenic machining and high pressure assisted machining in comparison to conventional machining. The sustainability performance measures refer to environmental impact, energy consumption, safety, personal health, waste management and costs. The sustainability evaluation is supported with machining experiments on high-temperature Ni-alloy (Inconel 718). It is shown that tooling costs are presenting the major contribution to the overall production costs, when hard-to-machine materials are machined, what is contradictory with previous analysis. Findings: As a result, it is shown that sustainable machining alternatives offer economic, environmental and social performance improvement in comparison to conventional machining. The results of the experimental part show that appropriate cooling/lubrication application can provide improved overall machining performance while satisfying sustainable issues in terms of enhanced machined surface quality, tool-life, chip breakability, power consumption and increasing productivity. Research limitations/implications: The Faculty of Mechanical Engineering in Ljubljana, Slovenia is implementing two new cutting strategies for the machining of a special material – Inconel. The first one is cryogenic machining and the second is material cutting by assistance of high pressure jet cooling lubrication. Both machining strategy are in rang of sustainable manufacturing. The implications of processes like those are not only nature friendly, but also modern spirit for producers and users of products. Originality/value: Paper present the technical description of two modern machining processes, the comparison of them and benefit, advantages and disantvantages. Really new is the strategy and opinion of spirit, which can be included in product over sustainable manufacturing processes.
