Langues : Anglais (eng) Catégories : Accumulateurs lithium-ion -- Recyclage Batteries électriques Économie circulaire L'économie circulaire est une expression générique désignant un concept économique qui s'inscrit dans le cadre du développement durable et s'inspirant notamment des notions d'économie verte, d’économie de l'usage ou de l'économie de la fonctionnalité, de l'économie de la performance et de l'écologie industrielle (laquelle veut que le déchet d'une industrie soit recyclé en matière première d'une autre industrie ou de la même). Son objectif est de produire des biens et services tout en limitant fortement la consommation et le gaspillage des matières premières, et des sources d'énergies non renouvelables ; Selon la fondation Ellen Mac Arthur (créée pour promouvoir l'économie circulaire1), il s'agit d'une économie industrielle qui est, à dessein ou par intention, réparatrice et dans laquelle les flux de matières sont de deux types bien séparés ; les nutriments biologiques, destinés à ré-entrer dans la biosphère en toute sécurité, et des intrants techniques ("technical nutrients"), conçus pour être recyclés en restant à haut niveau de qualité, sans entrer dans la biosphère Métaux -- Recyclage Véhicules électriques Index. décimale : 330.1 Systèmes et théories Résumé : In contrast to the linear economic model that has existed since industrialization, the concept of circular economy aims to reduce negative environmental impacts. There is a growing debate about the compatibility of increasing consumption with the Earth’s finite resources, calling for a system that minimizes losses. This concept is also of great interest for lithium-ion batteries (LIBs) because the key role of LIBs in the transformation of the mobility sector is expected to increase their production exponentially over the next few years. So far, there is no established business model that defines the further procedure with LIBs that have reached the end of their useful life. The aim of this study is to investigate the potentials and challenges of the circular economy and how they can be addressed using the case study of LIBs. The method of Systematic Literature Review is used to identify the relevant literature on this topic in a reproducible way while avoiding content-related distortions. The results are presented in a structured way and divided into the three topics of “reuse”, “repurposing” and “recycling” according to the circular economy approach. These are further divided into the subcategories of technical, economic, social, logistical, and ecological challenges, which are explained in detail and possible solutions are suggested.

Sustainability screening in the context of advanced material development for printed electronics / Florian Gehring in MATERIAUX & TECHNIQUES, Vol. 109, N° 5-6 (2021)

Note générale : Bibliogr.

The cornerstones for this development are conductive inks and adhesives that connect components and sensors with each other, integrating them into a printed environment. A decisive role hereby is played by advanced materials, such as functional inks, and their interaction in final devices for application in various use-cases. For this purpose, various particle structures in the nanometre range are created that enable the required conductivity, while keeping material input of the conductive substance as low as possible. Due to the excellent properties, the versatile functionalities, the possible high production volumes and the associated reduced production costs a wide range of applications is facilitated through printed electronics and mass markets become accessible. Therefore, associated environmental impacts as well as the security of the supply chain are expected to gain further relevance in the future. Yet, as most of the processes are in a development stage, prospective assessments before the start of production are essential, if development of printed electronics shall be aligned with sustainability goals. In order to address environmental consequences of future implementations of advanced materials for printed electronics at an early stage, this contribution is considering and evaluating the sustainable effects in a comprehensive assessment even before the physical start of product and material development. To this end, a procedure was developed, in which underlying methodology enables development engineers to identify hotspots at an early stage and to address and mitigate them early on. This way, challenges of tomorrow’s circular economy are already being addressed today and critical sustainability pitfalls can be avoided.

Influence of design properties of printed electronics on their environmental profile / Tobias Manuel Prenzel in MATERIAUX & TECHNIQUES, Vol. 109, N° 5-6 (2021)

[article]  inMATERIAUX & TECHNIQUES > Vol. 109, N° 5-6 (2021) . - 12 p Titre : Influence of design properties of printed electronics on their environmental profile Type de document : texte imprimé Auteurs : Tobias Manuel Prenzel, Auteur ; Florian Gehring, Auteur ; Franziska Fuhs, Auteur ; Stefan Albrecht, Auteur Année de publication : 2022 Article en page(s) : 12 p Note générale : Bibliogr. Catégories : Adhésifs conducteurs Durée de vie (Ingénierie) Electronique imprimée Encre électronique Environnement -- Etudes d'impact Matériaux -- Propriétés fonctionnelles Revêtement conducteur Index. décimale : 658.408 Ecobilan-Protection de l'environnement Résumé : In the context of an Internet of things (IoT) vision, printed and embedded electronics have gained serious momentum over recent years. Large leaps in innovation promote the applicability of the technology and help reduce device cost significantly. Additionally, printed electronics are often perceived as a green technology with high potential of replacing established subtractive manufacturing methods and act as an enabler in many areas of society. However, their environmental impacts are still rarely investigated thoroughly. Device development for printed electronics typically starts with the definition of functionalities rather than exact knowledge about components and materials, making an integrated early-stage life cycle assessment (LCA) of the devices challenging due to the typically large amount of possible technical solutions for each use case. This contribution fundamentally supports the idea that getting involved with environmental considerations as early as possible in the development is pivotal in avoiding sustainability pitfalls from the start. Consequently, several LCA studies are summarised focusing on three different sustainability scopes: material, production and device, as well as use-phase and end-of-life. The work aims to provide an overview over the sustainability potentials and risks of the production processes of printed electronics from flexible substrates and conductive inks based on micro- and nano-sized particles. Different filler materials for the inks are considered, as their impact heavily influences the overall device impacts. In conclusion, recommendations for further work in the field are derived, summarising potentials of printed electronics, while equally considering remaining challenges. Thus, the conducted work contributes to a better understanding of environmental impacts in the development of printed electronics and helps applying the findings already at the very first development stages Note de contenu : - MATERIAL SUSTAINABILITY SCREENING : Substrates - Conductive particles - Conductive inks and adhesives - Functional components - Further components and materials - PRODUCTION AND DEVICE SUSTAINABILITY : Production processes - Combinatory approach for assessing device sustainability - SUSTAINABILITY OF USE-PHASE AND END-OF-LIFE Référence de l'article : 506 DOI : https://doi.org/10.1051/mattech/2022016 Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=37745 [article]
