Automotive OEM introduced Product-Service Systems in the past 20 years, challenging their traditional business model. A qualitative study was developed to characterise the decision-making process across 6 case studies, and similar patterns across different enabled the identification of lessons learned and possible future implications. All PSS initiatives were introduced following an Agile/Lean experimental approach, but the opportunistic nature of trials casts doubts in future validity. New testing methods that generate more robust conclusions need to be developed.

While the “useful life” of products plays an important role in the balance of sustainability and lifecycle assessment, the concept of durability, as the main measure of useful life, is still ill-defined. This paper critically considers the limitations of the current definitions and approaches to durability, by reflecting on the complex interactions of the viewpoints of engineering design teams, users, society and business economics. A new definition is proposed for durability relating to the useful life goals for a product within its techno-socio-economic context.

Sustainable service-product systems (SPSSs) aided packaging-free shopping are expected to promote sustainable behaviour through enhanced user experience. Yet, understanding about this kind of practice is scarce. In this study, we adopted a qualitative approach through observations and semi-structured interviews with fifteen young consumers. The results present three stages of the practice and identify the challenges in each stage, using the practice theory as a theoretical basis. In light of these, the future offerings of SPSSs are proposed.

This paper aims to develop a risk assessment framework that addresses both the complexities of the risk landscape that green transition portfolios face, but is recognizable and easily understandable by stakeholders. For this purpose, we build upon the framework of NASA Technology Readiness Levels (TRLs). This study analyzes six existing readiness levels framework that are held towards uncertainty factors from the Green Transition. The TRL scale are coupled with Risk, Uncertainty, and Ignorance to score the individual level of uncertainty. The paper ends with suggestion for further studies.

To enable the circular economy paradigm, it is important to design easy-to-disassemble products. A new method, known as Design for Circular Disassembly (DfCD), has been proposed to enhance product disassembly performances toward circularity. The method was tested on a small-sized product, showing promising results. However, its applicability to medium-sized products remains unclear. The goal of this article is to assess the effectiveness of DfCD on medium-sized products, particularly washing machines. Results showed DfCD can be extended to medium-sized products, increasing model complexity.

Based on circular economy readiness assessments of six value chain layers, 18 design strategies and five collaboration strategies for circular economy were identified. The design strategies have many applications, from the design of materials, products, and processes to business models, and while some are specific to determined layers, others can be addressed by companies in multiple layers. Furthermore, collaboration across the value chain was found to affect positively the employment of circular economy design strategies, contributing to the fulfilment of solutions’ circularity potential.

Manufacturing companies find themselves at the crossroads of innovation and sustainability in an era of growing emphasis on corporate social responsibility. This paper delves into Design for Sustainability, aiming to understand the practices Italian design furniture companies are implementing towards sustainability through case studies analysis of sustainable actions (SA) showcased in Milan Design Week 2023. The study categorizes SA according to the Design for Sustainability Framework, determining their role in furniture companies’ transformative learning approaches towards sustainability.

The implementation of product-service systems (PSS) is prone to the occurrence of rebound effects (RE). This research aims to systematically identify the rebound mechanisms in a PSS context. Through the case study of a use-oriented PSS offer, we showcase a structured way to address RE that led to a comprehensive mapping of 23 mechanisms. The analysis demonstrates an approach to mapping rebound triggers, drivers, and mechanisms within the actors’ realms that designers can apply to ensure the potential sustainability gains of PSS offers.

The integration of sustainability into highly uncertain technology development is key to support manufacturing companies to reduce their environmental impacts. The use of future scenarios to support decision-making in early design for sustainability is promising, but there is a lack of systematic guidelines on how to build them. Through literature review and empirical research scenario-building guidelines were designed. The guidelines are step-by-step activities to be performed in workshops. Results suggest the guidelines were successful in building consistent, plausible, and useful scenarios.

Systems change can help to address sustainability challenges and interventions at deep leverage points of a system can be applied to do so. By studying 9 sustainable entrepreneurial businesses, this paper looked at how entrepreneurial firms used their business to intervene at deep leverage points to facilitate systems change. We then proposed how deep leverage points can be operationalized by developing an approach for sustainable business model innovation and how entrepreneurs can consciously target leverage points when designing their business models to influence sustainable systems change.

To advance the circular economy, there is a need to take an ecosystem view of business models for circularity in which different actors interact dynamically to create economic, environmental and social value. This research introduces the Circular Business Ecosystem Model Canvas, a novel method to prototype a circular ecosystem of business models. The case of ferric chloride, an inorganic coagulant for wastewater treatment, is used to demonstrate the new canvas and show how it supports the development of a more holistic perspective on sustainability-oriented business model innovation.

Multiple industries have hailed lightweighting promise to reduce the mass of their product at equivalent or improved performance. Lightweighting as a strategy encompasses lightweight end-product desired attributes and through-life processing decisions. Assessment of lightweighting gathers information for decision-making towards the optimization of these strategies. An exploratory study, using systems thinking is conducted, to identify requirements of lightweighting and its assessment in terms of holistically defining its impact on the sustainability of its background system, the Earth.

Many of the methods and tools proposed in the literature for validating product concepts are matrix-based, but they do not allow the results to be communicated easily and comprehensibly. This is a major obstacle to the integration of such methods. The poor communication of the results of a method therefore represents great potential for better integration of sustainability aspects in product development. In this article, an approach is proposed on how the results of the MECO matrix can be converted into a clear visualization of the reduced environmental assessments.

The growing emphasis on sustainability integrates eco-design and life cycle analysis into product development. Despite the value of LCAs, data limitations lead to assumptions, impacting accuracy. This study compares an estimation-based LCA with a data-driven approach, focusing on a laser machine's operational phase. The significant influence of resource consumption during operation underscores the necessity of optimization. Applying a data-driven approach reveals a 24% difference compared to the estimation-based method, emphasizing the challenges in obtaining accurate data for effective LCAs.

The paper presents a novel approach to visualize the impacts of design heuristics in sustainable product development. Focusing on the integration of ecological sustainability, our research introduces a multivariate visual approach, combining Sunburst Charts and Radial Heat Maps. The methodology, based on a description standard for design heuristics, enhances knowledge sharing and provides an intuitive tool for designers. A dynamic three-series radial heatmap facilitates comparisons across different product properties, fostering informed decision-making in product development.

Introducing new technologies in low-income contexts have potential for positive social impact, and such efforts are made by humanitarian engineering non-govermental organisations (NGOs). The impact can increase if a systemic sustainability perspective is considered in the design process. Sustainability criteria are identified using a literature study combined with an empirical study together with a Swedish NGO. These criteria are synthesized into a simplified Sustainability Fingerprint tool which is evaluated and deemed to be useful when introducing new technologies in low-income contexts.

This paper reviews I4.0 technologies for assessing sustainability, offering an SI framework in manufacturing and smart product design. Decision-makers can optimize environmental, social, and economic impacts in smart product design using this framework.

Reusable packaging systems are emerging as a promising solution to combat the growing issue of packaging waste. While consumers generally recognise the environmental advantages of reuse, their actual reuse behaviours may result in insufficient reuse and an unintentional undermining of sustainability efforts. We conducted two creative workshops, created a large number of potential design interventions and further developed them into 16 design strategies for consumers' continued usage of RPSs through thematic analysis. These findings can inspire future research and the development of RPSs.

This study, conducted with Northvolt, examines battery system recyclability and disassembly dynamics.
