Production of Circular Photovoltaic Systems

Production of Circular Photovoltaic Systems

The potential of digital technologies
Verena Luisa Aufderheide ORCID Icon
The circular economy (CE) promises a more sustainable use of resources by managing products in a cycle and striving for a transformation from a linear to a circular supply chain. In particular, digital technologies as enablers for the circular economy have been increasingly researched and applied in practice in recent years. This article describes which digital technologies offer potential for increasing circularity in the production of circular photovoltaic (PV) systems.

Dimensions of Industrial Openness

Dimensions of Industrial Openness

Understanding Openness and Its Implications for Sustainable Transformation
Nils Weiher ORCID Icon, Theresa Riedelsheimer ORCID Icon, Kai Lindow ORCID Icon
The topic of Openness is of growing importance for industry, especially in Europe. However, the term Openness is used very differently. Openness includes several concepts, including Open Source Hardware, Open Source Software, Open Data, Open Standards, Open Innovation, Open Science and Open Education. The concepts address different dimensions of Openness, all based on some kind of participation and with the goal to create more transparency and accessibility. This article defines the concepts and provides a basic understanding of their importance for industry and for greater sustainability.

Resilience in Circular Economy Supply Networks in the Context of Critical Mineral Resource Supply

Resilience in Circular Economy Supply Networks in the Context of Critical Mineral Resource Supply

Tom Pettau
The supply of CRM to domestic companies is threatened by disruptions (e. g. trade conflicts or shortages). Relocating production to stable regions is often not possible in the context of CRM due to geological reasons. One way out is CE. From a network perspective, the resilience must be improved and expanded to include viability. In CE for resilience improvement, a distinction must be made between ex-post and ex-ante CE. Ex-post CE is used as a reaction to a disruption and ex-ante CE reduces the probability of a disruption occurring.

Green Productivity for the Circular Economy

Green Productivity for the Circular Economy

Potentials through digitalization
Verena Luisa Aufderheide ORCID Icon
The Circular Economy (CE) is a form of economy that extends the use of products and resources by developing the linear supply chain (SC) to a circular SC. However, additional input factors are required for remanufacturing and recycling. Furthermore, these processes generate additional environmental impacts. It is questionable whether the circulation of products is only worthwhile from an economic point of view or whether it also brings environmental advantages. An approach that relates the economic impact of a product to its environmental impact is the Green Productivity Index (GPI). In the following, this index is developed for CE. Furthermore, this article examines how digitalization can positively affect the Green Productivity (GP) of CE. (Only in German)

Digitization of the work environment for sustainable production

Digitization of the work environment for sustainable production

Sustainability is gaining importance and the economy is changing into a circular economy, especially with regard to climate change and the need to create more resilient value chains. The organization of work is meeting these challenges with, among other things, the digitalization of increasingly changeable production. Collecting and understanding data is becoming increasingly complex, as not only internal production data is of interest, but also cross-company sustainability indicators play a role in decision-making. The research results presented under the main topic “Digitization of the work environment for sustainable production” address this problem of compliance with sustainability requirements by means of digitization and its impact on the workplace and workers. The members of the Scientific Society for Work and Business Organisation (WGAB) present innovative concepts and research results for practitioners and scientists and thus provide valuable input for current challenges.

Circular supply chain management for the wind energy industry – Conceptional ideas towards more circularity

Circular supply chain management for the wind energy industry – Conceptional ideas towards more circularity

Supply chains have to be designed and managed to handle complexity and uncertainties. Recent events (e.g. Covid-19) have shown how fragile supply chains can be when assumptions for the design and management of supply chains are challenged. In addition, governments are striving for systemic changes towards more sustainability (e.g. European Green Deal). To meet the resulting requirements, the concept of circular economy and with it, circular supply chain management (CSCM) are gaining attention as they could contribute to building a sustainable and resilient system. The German wind energy industry, with its long track record, is a suitable application for further research on CSCM, as the industry operates predominantly in a linear system and relies on finite materials. Despite, research on CSCM for the wind energy industry is still rare. The aim of the paper is therefore to present conceptional ideas that enable an efficient design of a circular wind energy industry in Germany. Aspects ...

Circular Economy – Chance for Innovation

Circular Economy - Chance for Innovation

Tobias Berndt, Claus Lang-Koetz, Silvia Rummel
Circular Economy is considered one of the most promising concepts on the way to a more sustainable economy. Expectations of a responsible corporate orientation are rising: This is shown by a recent ruling of the Federal Constitutional Court, which demands that Germany must be more ambitious in its climate goals [1]. The EU Green Deal envisages climate neutrality by 2050 and the “Circular Economy Action Plan” calls for more effective use of resources and reserves [2]. This article describes a method that companies can use to develop ideas for circular business models.

Circular Product Lifecycle Management

Circular Product Lifecycle Management

Strategies to Support a Circular Transformation
Laura Montag, Marion Steven
The challenges facing production in the 21st century are multifaceted and complex. In particular, the consequences of global warming have fundamentally changed the conditions for modern production. In dealing with these challenges, the circular economy is seen as having great potential. This article develops a strategy for the successful implementation and realization of the circular economy for a climate-friendly production. For this purpose, a holistic circular product lifecycle is developed, along which circular strategies are systematically identified. The concept is illustrated by a practical example of a smartphone manufacturer.
