Research on premature obsolescence

On this page, you will find results from the PROMPT research on premature obsolescence. Please note, that some of the deliverables still have to undergo an external review as part of the Horizon 2020 process. However, since the topic of premature obsolescence is moving fast, the consortium decided to make the deliverables already available to the public. When citing the work, please also quote the version number of the deliverable.

D.2.6: State-of-the-art knowledge on user, market and legal issues related to premature obsolescence

Lead Partner: TU Delft

Date of the Deliverable: 30/04/2020

This deliverable provides an overview of the state-of-the-art knowledge on reasons to replace products addressing user, market and legal aspects. The data used for this report is from both scientific literature and reports from consumer associations. The report shows an overview of (scientific) literature and gives insights from consumer studies related to the user and market issues of premature obsolescence. The literature study consists of two parts. The first part covers a general overview of the different types of (premature) product obsolescence that exist and the general reasons why people replace their products. The second part provides information on the average lifetime, expected lifetime, replacement motivations, barriers towards repair activities, national differences in repair activities and possibilities for lifetime extension. The last chapter provides an analysis of existing legal provisions on guarantee and repair for elements that might be promoting or hampering products to be repaired.

Please note, that this is the first version of the deliverable and might be subject to changes after the periodical review as part of the H2020 project process.

D.2.5: Environmental evaluation of current and future design rules

Lead Partner: Fraunhofer IZM

Date of the Deliverable: 29/04/2020

Thie deliverable “Environmental evaluation of current and future design rules” has three main objectives. First, in the context of the global market situation, it identifies current and future design trends for selected product groups and discusses their environmental impact. Second, it shows a comparison of different existing life cycle analyses (LCA) in order to identify hot spots that are most relevant from an environmental point of view, with a focus on resource efficiency and possible lifetime extension. Third, it analyses environmental break-even points identified in the literature and discusses the advantage of possible lifetime extension.

Please note, that this is the first version of the deliverable and might be subject to changes after the periodical review as part of the H2020 project process.

D.2.4: State-of-the-art of design strategies and design principles in relation to obsolescence

Lead Partner: TU Delft

Date of the Deliverable: 29/02/2020

This deliverable presents an overview of design strategies, design principles and design features in relation to obsolescence based on literature and state-of-the-art in repair practice. The results presented are preliminary in the sense that they are the result of an initial exploration in a broad field to extract the information most promising for further research in future deliverables of PROMPT. It provides an overview of barriers, various scoring systems, and reports from partners in order to extract design features facilitating and hampering longevity of products. Finally, using these results, an inventory of design strategies and principles, and its relation to different design features are generated and analysed. This inventory will be elaborated and built upon for the development of tests on design aspects in future deliverables of PROMPT.

Please note, that this is the first version of the deliverable and might be subject to changes after the periodical review as part of the H2020 project process.

D.2.3: State-of-the-art existing testing, rating systems and standards

Lead Partner: OCU

Date of the Deliverable: 20/12/2019

The deliverable “State-of-the-art existing testing, rating systems and standards” summarizes existing information regarding tests, rating systems and standards in so far as they include relevant aspects concerning premature obsolescence for products within the scope of the PROMPT project. It points to existing features and issues that dominate product obsolescence (such as bearing failure, high repair cost and commonly used protocols). In addition, it provides examples, references and background information for future work, reports or dissemination campaigns.

Please note that the current version of the report is not final since it is a “living document” that will be updated throughout the study. If you have any comments or suggestions that should be added to the report, please contact us at info@prompt-project.eu.
