Short Biography

Damjan Krajnc earned his PhD in chemical engineering from the University of Maribor. His research focuses on Life Cycle Assessment, Eco-design, Sustainable production metrics and indicators, Industrial ecology, Sustainable process design and Environmental management. He transmitted the results of his scientific research activities to industrial practice within the framework of several, mostly international projects. These involve the integration, innovation, development and marketing of environmentally friendly products and processes, the supply of heat to the industry (EINSTEIN), the sustainable sugar industry (TOSSIE), »The development of strategic scenarios and optimal structures of sustainable production of biofuels in Slovenia« etc. He was coordinator of the ECO-HUB project within the framework for the cross-border cooperation of the Slovenia and Hungary in the financial perspective 2007-2013. He has collaborated in two “Partnership in Science” projects of the British council (“Integrated Design of Sustainable Chemical Processes”, and “Sustainable Production Indicators and Reporting of Sustainability, SPIRS). For his research work, he received the Krka Award for Excellence in Research, 2006. He is the recipient of financial support from the World Federation of Scientists, 2004.

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.
