Item type:Publication, Access status: without files , Digital twins for the circular economyDespite efforts by politics and society to create a circular economy, the transition is taking place slowly. A central prerequisite for keeping products and the raw materials they contain in the cycle is the inter-organizational exchange of product information, e.g. regarding the product composition. In the absence of such information, landfilling or incineration of products after use are often the only options. In this context, digital twins as a digital representation of a product allow not only the provision of required information, but also updating it over the course of the product’s life. Based on a research project of the Hamburg University of Technology (TUHH) and the Kühne Logistics University (KLU), this article shows which role digital twins can play on the way to improved information exchange and thus a circular economy.Publicationtype: Journal Article61 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , CIRCuIT – Umsetzungsstrategien für zirkulare und regenerative Städte in Europa(2021-06-08); ; ; Cities and urban centres are driving the transition to a regenerative, resource- and material-efficient circular society. At the same time, they represent large material stocks and can already cover a relevant share of their demand for mineral resources from these deposits. Accordingly, more than 80 % of construction waste and residues are recycled regionally in the EU today. However, this is often happens in a low-value form, for example as filling material in dam or road construction. Significantly higher environmental benefits can be achieved through the reuse of components and materials or a high-value recycling of construction materials. This is the aim of the Horizon2020 project CIRCuIT, with which the cities of Copenhagen, Hamburg, London and the Helsinki region are willing to increase their transformation to circular cities through the reuse of buildings and infrastructure, the reuse of building components and high-quality recycling by at least 20 %. The City-Cluster Hamburg is also developing a roadmap for the use of recycled concrete as part of the project.Publicationtype: Journal Article257
