Trade-offs between sustainability criteria and engineering design variables can lead to sub-optimisations and costly short-term priorities. This study explores how sustainability requirements can be identified and integrated in product requirements to guide strategic and tactical decisions in product development including sustainability perspectives. Literature review and action research resulted in a proposed systematic approach that: define sustainability criteria and indicators; use correlation analysis with QFD; and adds identified specific sustainability requirements to requirement list.

There are high expectations of additive manufacturing (AM) as a technology to improve manufacturing efficiency and reduce material waste. This study aims to clarify the sustainability advantages and challenges of AM technologies used in industry by testing and applying a strategic sustainability life cycle assessment in the early development stage. The result showed possibilities from using the tool and some areas of certain interest regarding improvement potentials of the AM technologies, i.e. value chain management, concept design, optimized material usage, and social sustainability.

Sustainability has shifted from strategically important to business critical for several manufacturing industries. This paper introduces an implementation framework to increase the capabilities in companies to design, develop and offer sustainable product-and production solutions in line with new regulatory strategies and plans.Based on a questionnaire survey, conducted in ten different product development companies representing different industrial sectors, the status and needs of sustainable product development were captured. Further on, a better understanding of the capabilities for a forthcoming digital sustainable product development support, were identified in an action research-based approach with three industrial companies. This paper presents the rational of a digital sustainable product development support, in relation to global sustainability goals and societal dimensions of sustainability transitions. The main results from the questionnaire presents the challenges and needs of capabilities for product developers and design engineers to develop more sustainable solutions in a resource efficient way. The action-based research with the three industrial manufacturing partners resulted in a set of common key activities and detailed requirements for a digital sustainable product development support. Finally, the paper describes a first prototype of a digital platform, i.e. Digital Sustainability Implementation Package-DSIP, and discusses future work.

In this research some systemic forces to sustainable design are described and mapped out, along with key areas, dimensions and stakeholders. These results are visualized in a causal loop diagram (CLD), which was the outcome of a group model building approach supported by a literature review. Within the proposed system model, represented by the system-level variables and their relationships within the CLD, some potential leverage points that can help make product design better contribute to sustainability are identified and described. These can be found in the balancing and reinforcing feedback loops of the CLD as well as the mapping to societal dimensions of sustainability transitions and stakeholder groups. Among the stakeholder groups, business managers, scientific researchers and engineering designers can be tied to the design community. Future research is proposed to build on these initial results to deepen the knowledge about the systemic drivers and barriers and leverage the contribution of design practice to sustainable development.

This research proposes a group model building workshop method that uses causal loop diagrams to foster capabilities for sustainable product development based on feedback and observations from several cases. The method's potential to enhance sustainability system thinking skills and to identify relationships between sustainability criteria and traditionally identified requirements is evaluated. The method can trigger discussion, visualize complexity and dependencies of sustainable design problems. Other application areas are e.g., sustainability training for practicing engineers and students.
