The transformation from linear to circular production is cornerstone for mastering sustainability. The fundamental aspect is that products from the utilization phase are fed back into the production phase, and a corresponding reverse supply chain exists for this purpose. Although various models for supply chain networks for value-retention circular economy strategies already exist in the scientific literature, there is a lack of decision rules for designing a suitable supply chain network. This paper aims to derive characteristics for selecting an appropriate supply chain network for value-retention circular economy strategies and to discuss rules of action based on case study research according to Yin.
Information-based Integration of Life Cycle Assessment into IT Landscapes of Manufacturing Companies
(2024)
Life Cycle Assessment (LCA) is one of the fundamental methods to facilitate effective decisions in sustainability transformation. However, the current implementation of LCA is inefficient due to detached software applications and manual data imports. Utilizing data from existing information systems offers the potential for a significant increase in efficiency. Existing approaches focus on prototypical implementations with a high level of detail but low transferability, or approaches only consider integration at the system level, whereby practical applicability is reduced. Therefore, this paper presents an information-based framework for integrating LCA software into the existing IT landscape of manufacturing companies with focusing on generic functions and a detailed information flow. The generic approach enables transferability, while the detailed information flows allow practical applicability.
The transition from linear to circular value-preserving models poses significant challenges, particularly in the context of Reverse Logistics. Variability in returned products in terms of time and quality and logistical complexities referring to decentralized and central factories hamper implementation. While digitalization offers the potential to optimize these processes, many companies lack a structured, scalable, and interoperable approach for integrating digital tools into Reverse Logistics. Moreover, the concept has largely been neglected and limited to managing returns from quality and warranty claims. Existing Enterprise Architecture Models frequently fall short in addressing challenges such as product condition and variability, independence from proprietary systems, and the integration of multiple Circular Economy (CE) strategies thereby constraining their practical applicability. The present paper aims to address these gaps by proposing a generic, vendor-independent, data-driven architecture model that enables companies to implement efficient, sustainable Reverse Logistics in alignment with CE goals. This model fulfills the pressing need for practical frameworks that support interoperability, reuse of existing IT infrastructure, and comprehensive process transparency. Consequently, organizations will be empowered to implement smart Reverse Logistics and to meet regulatory demands, resource efficiency targets, and consumer expectations for sustainable products. Furthermore, the model should serve to meet national and supranational environmental protection targets.
Gap Analysis for CO2 Accounting Tool by Integrating Enterprise Resource Planning System Information
(2023)
Detailed carbon accounting is the foundation for reducing CO2 emissions in manufacturing companies. However, existing accounting approaches are primarily based on manual data preparation, although manufacturing companies already have a variety of IT systems and resulting data available. The gap analysis carried out based on the GHG Protocol and an reference ERP system shows how much of the required information for CO2 accounting can be integrated from an ERP system. The ERP system can cover 20 % of the required information. The information availability can be increased to 49 % through additionally identified modifications of the ERP system. Integrating the CO2 accounting tool with other systems of the IT landscape, e. g. Energy Information System, enables an additional increase.
Transitioning to a circular economy fundamentally changes the traditional, linear economic model. Establishing circular strategies requires adapting and expanding the roles within the value system to realize the decoupling of economic growth and resource consumption. In particular, a combination of several value-retention strategies implemented in parallel can increase the ecological and economic potential of circular economy. However, there is a lack of description of this type of value system in relation to the new required activities, and the resulting material and information flows within the value system. For this reason, literature research and exploratory analyses through expert workshops were used to identify variants for implementing the value system. The results include the definition of five possible variants of a value system for the parallel implementation of value-retention circular strategies in the white goods industry. The five possible variants are necessary to enable sustainable collaboration strategies between different stakeholders from which all of the stakeholders can benefit. The new activities for enabling the various value-retention strategies, e.g., product evaluation or disassembly, are distributed differently across the stakeholders of the value systems per variant. This leads to distinct material and information flows per variant.
Nachhaltigkeit folgt nicht nur aus Regulatorik – sie lohnt sich auch wirtschaftlich. Durch gezielte Integration von Softwarebausteinen im Bereich CO2-Bilanzierung, ist eine effiziente Bilanzierung möglich. Die bestehenden Stammdaten des ERP-Systems werden erweitert und mithilfe von extrahierten Bewegungsdaten wird eine kontinuierliche Bilanzierung ermöglicht.
