Leveraging Business Process Management for Sustainable Transformation: Case Study of MECK Decarbonization Strategy
(Wydawnictwa AGH, 2024) Szelągowski, Marek; Berniak-Woźny, Justyna; Zawalich, Beata; Radziszewski, Bartosz
The heating sector is a critical focus for climate-change mitigation, as it accounts for 40–50% of global energy consumption and remains a major source of greenhouse gas (GHG) emissions. Miejska Energetyka Cieplna sp. z o.o. (MECK), a municipal heating company in Poland, faces an urgent need to undergo green transformation in order to comply with the Corporate Sustainability Reporting Directive (CSRD) and European Sustainability Reporting Standards (ESRS). This study aims to demonstrate how business process management (BPM) can be effectively applied to support MECK’s transition toward sustainable practices, ensuring its compliance with CSRD and ESRS requirements while fostering long-term profitability and competitiveness. Through the application of BPM, MECK has successfully embedded sustainability into its operations; key achievements have included developing actionable insights for process improvements, decarbonizing operations, reducing waste, creating new sustainable products, and adhering to CSRD and ESRS reporting standards. These efforts have enhanced MECK’s ability to secure long-term profitability while significantly improving its environmental sustainability. This case study highlights the pivotal role of BPM in enabling heating companies to meet regulatory requirements and advance their sustainability agendas. MECK’s experience underscores the importance of data quality, transparency, process optimization, and continuous improvement as foundational elements for achieving sustainability goals.

Ścieżki transformacji polskiej energetyki
(Wydawnictwa AGH, 2023) Suwała, Wojciech; Wyrwa, Artur; Tokarski, Stanisław
W artykule omówiono cztery ścieżki transformacji krajowego systemu elektroenergetycznego prowadzące do obniżenia emisji $CO_{2}$ do poziomu 10 mln ton w 2050 r., zróżnicowane pod względem roli, jaką odgrywają w nich wybrane technologie energetyczne. Zostały one opracowane za pomocą modeli TIMES-PL oraz MEDUSA, w których optymalizowano rozwój krajowego systemu elektroenergetycznego pod kątem najniższych kosztów osiągnięcia celu dekarbonizacji. Z przedstawionych w artykule badań wynika, że zapewnienie ciągłości dostaw energii, która w przyszłości będzie wytwarzana przede wszystkim ze źródeł odnawialnych, wymaga znaczącego udziału źródeł sterowalnych (jądrowych lub klasycznych, wyposażonych w systemy sekwestracji dwutlenku węgla) oraz magazynów energii.

Decarbonization of steel making and allied processes have been receiving immense attention of researchers. Similarly, recycling of waste resources and conversion or recovery of useful materials from waste destined for landfills to mitigate environmental impact, is also an important area of research. Ferrosilicon (FeSi) is currently produced using carbothermic reduction and an energy intensive process. However, silicon (Si) from electronic wastes could be combined with scrap steel to produce FeSi. The Si from electronic waste will, however, contain some impurities such as Aluminium (Al), copper (Cu) and Tin (Sn), which could be incorporated into the FeSi produced from such Si. Hence, in this work the impact of the impurities on the properties of FeSi was investigated theoretically and systematically with the help of FactSage simulations. The impact of three major impurities associated with recycled Si (Al, Cu and Sn) were analysed when present individually and then all together. The analysis was done with the help of phase diagrams for solidification process occurring under equilibrium conditions. It was found that the impurities impact the proportion of the final phases and the melting and phase-transition temperatures. Further, the presence of different intermetallic phases could impact the mechanical properties of the alloy as well. The presence of three impurities together with Fe and Si leads to a complex multicomponent system. While further experiments are needed to identify the actual phases formed during such process, this work provides as framework for carrying out such experiments in the future.
