    Product-service systems (PSS) are often presented as an inherently sustainable business model. The argumentation is often based on theoretical considerations, which cite circular economy (CE) characteristics in PSS business models as an explanation. In this paper we examined to what extent positive and negative sustainability effects of PSS could actually be observed, based on use cases. For this purpose, we conducted a systematic literature review and analyzed the statements on sustainability effects based on the triple bottom line approach. We find that positive sustainability effects, especially on the environmental sustainability of PSS, are described disproportionately often, which may be indicating a possible publication bias. In addition, the methods used to derive statements on sustainability effects are very heterogeneous and often unsystematic, making it difficult to compare the described effects. Furthermore, we were able to identify drivers that are particularly often considered in literature to be responsible for sustainability effects. As a result, we were able to derive direct implications for future research in the field of sustainability assessment of PSS.

    Investigating challenges of a sustainable use of marine mineral resources

    High-tech products as well as renewable energy systems require ever-increasing quantities and more different metals. The extraction of metals and industrial minerals for the production of consumer goods and machines take place almost exclusively on land now. However, the interest in marine mineral resources has been re-inflamed due to the problem of geopolitical availability, such as fragile or failed raw material states and oligopolistic structures among the producers. This article gives a brief outline of the political, social and economic context of this change in interest in marine mineral raw materials extraction.

    Study on sustainability developments in industrial practice

    Traditionally, manufacturing companies focus on the value-adding processes at production sites but during the last decades, life-cycle thinking is emphasized. The principle of Sustainable Development contributes as a significant driver for this way of thinking. It demands manufacturing companies to implement sustainable aspects into their engineering actions. The state of the art shows that theoretical solutions to integrate sustainability into a company exist at all corporate levels (normative, strategic and operational). Against this background, the question arises how companies are actually implementing sustainability. Within this study, the company's internal implementations were examined. Eventually, the need for action is identified and future recommendations are described.
