Transitioning towards Net-Zero Emissions in Chemical and Process Industries : A Holistic Perspective
Peter Glavič, Zorka Novak-Pintarič, Helena Levičnik, Vesna Dragojlović, Miloš Bogataj, 2023, review article

Abstract: Given the urgency to combat climate change and ensure environmental sustainability, this review examines the transition to net-zero emissions in chemical and process industries. It addresses the core areas of carbon emissions reduction, efficient energy use, and sustainable practices. What is new, however, is that it focuses on cutting-edge technologies such as biomass utilization, biotechnology applications, and waste management strategies that are key drivers of this transition. In particular, the study addresses the unique challenges faced by industries such as cement manufacturing and highlights the need for innovative solutions to effectively reduce their carbon footprint. In particular, the role of hydrogen as a clean fuel is at the heart of revolutionizing the chemical and process sectors, pointing the way to cleaner and greener operations. In addition, the manuscript explores the immense importance of the European Green Deal and the Sustainable Development Goals (SDGs) for the chemical industry. These initiatives provide a clear roadmap and framework for advancing sustainability, driving innovation, and reducing the industry's environmental impact, and are a notable contribution to the existing body of knowledge. Ultimately, alignment with the European Green Deal and the SDGs can bring numerous benefits to the chemical industry, increasing its competitiveness, promoting societal well-being, and supporting cross-sector collaboration to achieve shared sustainability goals. By highlighting the novelty of integrating cutting-edge technologies, addressing unique industrial challenges, and positioning global initiatives, this report offers valuable insights to guide the chemical and process industries on their transformative path to a sustainable future.

Methodology for assessing sustainability of an air transport system
Milan Janić, 2002, original scientific article

Abstract: Assessment and operationalisation of the concept of a sustainable air transport system have been recognised recently as an important but complex research, operational and policy tasks. In the scope of the current academic efforts to properly address these problems, this paper develops methodology for assessing the sustainability of an air transport system. The methodology is based on the indicator systems of sustainability defined for the operational, economic, social, and environmental dimensions of the system performance. The measures are defined for each indicator to express the systemeffects (benefits) and impacts (costs) for particular actors such as the system users--air travellers, air transport operators, aerospace manufacturers, local community members, local and central government. They are assumed to evaluate the system sustainability with respect to the values of selected indicators. Generally, for all of them the system will be sustainable if the indicators representing effects (benefits) are as high as possible and increase with increasing system output, and the indicators representing impacts (costs) are as low as possible and decrease with increasing system output.

Improving the economic and environmental performances of the beet sugar industry in Slovenia: increasing fuel efficiency and using by-products for ethanol
Damjan Krajnc, Miro Mele, Peter Glavič, 2007, original scientific article

Abstract: This paper investigates the possibilities of attaining zero-waste emissions inthe case of sugar production. The case-studied sugar plant located in Slovenia reflected a typical plant, using traditional sugar production from beet. An investigation of the possible use of waste and by-products from sugarprocessing was carried out, in order to approach zero-waste from beet sugar processing. The sugar production process was simulated and optimization was carried out concerning energy utilization. Consumption of energy in the chosen sugar plant was lowered by simultaneous optimization of the evaporationand crystallization process. Changing the fuel type used in the case-studied sugar plant (replacement of heavy fuel oil with natural gas) produced a significant decrease in air emission. Opportunities in the sugar industry have been discovered for adapting to new market conditions through the optimization of combined sugar-ethanol production. The two proposed options have been economically and environmentally evaluated and compared.

Assessment of the consequences of accident scenarios involving dangerous substances
Zorka Novak-Pintarič, 2007, original scientific article

Abstract: This paper highlights the major steps in the procedure for evaluating the consequences of accidents involving dangerous substances, especially during storage, loading and unloading activities. The procedure relies on identifying accident scenarios that could be encountered in particular plants, followed by modelling of these scenarios by means of available modelling systems. Finally, the resultant outcomes are identified, together with their effects on both people and property. The resources needed to perform this proceedure are discussed, in order to clarify the roles of operators, external experts and other institutions when evaluating any accident conesquences. Four examples, all relevant in industrial practice, are given in order to illustrate the procedure: the releasing of liquefied petroleum gas, flammable organic solvents, toxic chlorine, and fuel oil. The results of these studies may be used for a quick order-of-magnitude estimation of accidents consequences.

How to compare companies on relevant dimensions of sustainability
Damjan Krajnc, Peter Glavič, 2005, original scientific article

Abstract: Dozens of frameworks of sustainability assessment that focus on the performance of companies have been suggested by now. They propose using numerous sustainability indicators, which are generally measured in very different units. While it is important to assess sustainability with several indicators, it may sometimes be difficult to make comparisons among companies based on a large number of performance measurements. This paper presents a model for designing a composite sustainable development index that depicts performance of companies along all the three dimensions of sustainability-economic, environmental, and societal. In the first part of thepaper, the procedure of calculating the index that would enable comparisonsof companies in specific sector regarding sustainability performance is presented. However, the emphasis of the paper is on the second part, where the effectiveness of the proposed model is illustrated with a casestudy in which two companies from specific sector are compared regarding their sustainability performance.

Dynamic effects of international fragmentation of production : empirical analysis of Slovenian manufacturing firms
Anže Burger, 2009, doctoral dissertation

Abstract: An increasing number of firms outsource peripheral functions in order to stay focused on their core capabilities. This dissertation contributes to a limited body of theoretical and empirical research on the relationship between intermediate inputs offshoring and firm productivity. The main aim of the dissertation is to study the effects of vertical fragmentation on firm productivity. In tight relation to the primary aim, I attempt to provide evidence for the focusing on core capabilities as one of the transmission channels through which imports boost firm productivity. Namely, the main hypothesis of the dissertation states that firms can exploit international outsourcing not only as an efficient means to cutting production costs and enhancing the quality of the inputs, but can use it as a leverage to direct scarce resources on their core business activities. By outsourcing standardized, peripheral components and activities, firms can better concentrate on activities such as research, innovation, sales and marketing, and increase their energies on matters that directly affect competitive positioning.
