Companies are pivotal in transitioning from a linear economy to a sufficiency-based circular economy. However, circular research lacks the necessary tools and processes to engage companies, customers, and downstream suppliers in preserving the value of their products post-launch. Effective value preservation requires close collaboration among producing companies and their ecosystem stakeholders to identify when value is decreased or destroyed over the product’s lifetime and to develop shared strategies to preserve or increase this value. This paper contributes to the development and empirical evaluation of the Circular Value toolkit. Based on demonstration with 15 SMEs and 24 PhD students, we found that the Circular Value toolkit supports companies in 1) identifying the points in the product lifetime where value is currently decreased or destroyed; 2) developing ideas and concepts to prevent value destruction; and 3) identifying barriers and opportunities for initiating collaboration with ecosystem stakeholders to ensure the efficient preservation of product value throughout the product’s lifetime. A valuable next step will be to validate the toolkit’s long‑term effects and examine its implementation within large organisations. ... Read more

Extending product lifetimes is central to advancing the Circular Economy (CE), as it enables the retention of value for both first and successive users (Geissdoerfer et al. (2017). Yet in many consumer markets, products are still prematurely replaced—whether due to loss of functional value or other, often subjective, perceptions of diminished worth (Magnier and Mugge, 2022). Many of these discarded products fail to enter reuse markets, leading to significant value loss and exacerbating environmental pressures such as CO2 emissions, material depletion, and e-waste (Bakker et al., 2014).

The fifth Product Lifetimes and the Environment Conference (PLATE 2023) brought together researchers and practitioners to deepen understanding of how extending product lifetimes can contribute to a CE . This special issue, a direct outcome of PLATE 2023, compiles new insights and empirical research that underscore the importance of retaining product value throughout the product life cycle. A key theme across the contributions is the shift away from merely improving recycling systems toward prioritizing inner-loop strategies—reuse, repair, refurbishment—and systemic lifetime extension.

This special issue covers diverse product categories—ranging from ICT and fashion to children’s goods and electric vehicle batteries—and examines value retention from multiple disciplinary and stakeholder perspectives, including design, business, policy, and environmental assessment. The 24 included articles are organized under six thematic sections: 1) Organisational perspective to circular value retention; 2) Longevity in fashion; 3) Changing consumer behaviors for longevity; 4) Design for longevity tools; 5) Policies and eco-systems for longevity; and 6) Environmental impact assessment of longevity. Together, these contributions reflect the state of the art in product lifetime research and provide valuable guidance for academia and practice in navigating the transition to a more circular economy. ...

Value preservation is key for the transition from a linear economy to a sufficiency-based circular economy. However, to keep the value of products and materials at the highest level possible over time, different actors such as businesses, designers, consumers, and policymakers must know when value is reduced during a product's lifetime, and how to capture and preserve this value. This study results in a comprehensive mapping of factors with a negative impact on the perceived value of products from a consumer's perspective and suggests new routes to value preservation, as a way of turning the negative factors into positive changes. Next, the paper presents a conceptual model for value preservation. The model identifies new key actors: value transformers (product developers), value co-operators (consumers), value gatekeepers (businesses), and value accountants (policymakers) and suggests important changes to their linear practices, which are needed for the sufficiency-based circular economy paradigm to flourish. ...
