Digital technologies (DTs), such as the Internet of Things, big data, artificial intelligence, or blockchain, are considered as enablers for a more sustainable and circular economy. So far, literature on these topics has mostly focused on specific DTs and subareas of sustainable product management (SPM). The aim of this paper is to provide a more comprehensive overview of current and potential examples of DT applications in SPM (e.g., product design/assessment, supply chain management, and business models). The collected examples (n = 146) were analyzed based on a systematic literature review, using quantitative and qualitative content analysis. Deductive and inductive analyses of the examples revealed the potential of DTs in terms of their usability along the product life cycle, their role as enablers for circular economy strategies and in specific SPM activities. DT application often entails only incremental improvements, for example, increased efficiency of existing processes, with more radical forms of improvement remaining relatively scarce. There is clear room for greater adoption and optimization of DTs, in various areas of SPM, so as to accelerate the transition towards a more sustainable and circular economy.

Interorganizational collaboration and the use of new digital technologies, such as artificial intelligence (AI), big data analytics, internet of things (IoT), or blockchain technology, are regarded as key enablers in implementing sustainability and circular economy‐oriented practices. While this is reflected in a few conceptual and case studies, statistical analyses on the topic are rare. No study so far has focused on collaboration, and digital technologies have only been studied in isolation. Therefore, the purpose of this study is to investigate the effect of interorganizational collaboration practices on a firm's circular economy practices and on outcomes (sustainability performance and economic performance), as well as the potentially facilitative role of new digital technologies on both. The research is based on a deductive approach, using a random sample of 112 Austrian manufacturing companies. The study employs partial least squares structural equation modeling (PLS‐SEM), features a multiple‐respondent design, and uses the dynamic capabilities view as a theoretical foundation. The study finds that interorganizational collaboration practices have a strong positive effect on the implementation of sustainability and CE practices, while the use of new digital technologies and general dynamic capabilities do not. The use of digital technologies positively affects only interorganizational collaboration, while general dynamic capabilities serve as an antecedent for both the use of digital technologies and interorganizational collaboration. Regarding the outcomes of CE implementation, the study finds a positive impact on firm‐level sustainability and economic performance. From a theoretical point of view, the study provides a new perspective on the prerequisites for successful CE implementation, highlights the importance of collaboration, and contextualizes the role of new digital technologies and dynamic capabilities. From a practical point of view, based on the positive outcomes found, the study supports arguments in favor of company engagement in CE activity. It also serves to motivate purposive digitization and systems thinking in order to create efficient CE collaboration networks.
