Developing circular building components: Between ideal and feasible

van Stijn, A. (author)

Creating a circular economy within the built environment plays a crucial role in society’s pursuit to become more sustainable. A building consists of building components, such as a kitchen, façade and roof. By replacing building components with more circular ones during new construction, maintenance and renovation, we can gradually make...

Sparking the Repair “Can-Do” Attitude: Enhancing Users’ Willingness to Repair through Design Support in Fault Diagnostics

van den Berge, R.B.R. (author), Magnier, L.B.M. (author), Mugge, R. (author)

Current production and consumption patterns of consumer electronics have a negative impact on our environment. Designers can contribute to changing these patterns with more sustainable product design. Prolonging product lifetimes can have a positive impact, for which repair is a promising solution. However, the fact that a product can be...

Repair in the circular economy: European Legislation, Product design and Business models

In this white paper, experts from science and practice share their knowledge of product repair. Repair is an important pillar of the circular economy as it is more efficient to repair a product than to completely dismantle or destroy it and recycle the materials. European legislation promoting repair is in the process of being adopted.<br/>

Why Circular Business Models Fail And What To Do About It: A Preliminary Framework And Lessons Learned From A Case In The European Union (Eu)

Baldassarre, B.R. (author), Calabretta, G. (author)

The circular economy aims to decouple economic growth from negative environmental impacts. To achieve this goal, circular economy concepts and policies must be implemented in practice by organizations through new circular business models. However, organizations often fail to implement circular business models on the market at scale. This is a...

Strategic design for remanufacturing

Boorsma, N.E. (author)

BoorsmaRemanufacturing is one of the product recovery approaches in a circular economy. In the remanufacturing production process, used products are returned to their original product specifications. When compared to original manufacturing, remanufacturing results in lower raw material consumption and reduces carbon emissions. Despite having...

From surgical waste to medical products

van Straten, Bart (author)

Hospital waste has a major impact on the environment. The worldwide growth of hospital waste is the result of the growing world population and the increase in use of disposables. A circular healthcare economy may contribute to the reduction of hospital waste. The circular economy is a system in which waste is prevented and where waste is reused....

Reviving the milk man:: Consumers’ evaluations of circular reusable packaging offers

Magnier, L.B.M. (author), Gil-Pérez, I. (author)

The question of prolonging the lifetime of food packages before they are disposed of has largely been overlooked. Yet, reusing packaging could bring interesting environmental benefits. In this research, we take a consumer perspective and test whether returnable packaging for fast-moving consumer goods (FMCG) has the potential to be adopted by...

A poorly educated guess: consumers’ lifetime estimations, attitudes towards repairability, and a product lifetime label

van den Berge, R.B.R. (author), Magnier, L.B.M. (author), Mugge, R. (author)

Consumers’ expectations about product lifetimes have an influence on the actual lifetimes. Promoting repairability and a product lifetime label can potentially encourage consumers to extend product lifetimes. In this paper, we present in-depth insights in how consumers make estimations about product lifetimes, and their attitudes towards...

Buying new or refurbished?: The influence of the product's durability and attractiveness, contamination risk and consumers' environmental concern on purchase intentions of refurbished and new products

Wallner, T.S. (author), Magnier, L.B.M. (author), Mugge, R. (author)

This research investigates how a durable and attractive product appearance, the perceived contamination risk, and consumers' environmental concern influence the purchase intentions of refurbished products. Consumers often have lower purchase intentions of refurbished products because they associate them with lower durability and fear that they...

The Circularity Calculator: A tool for circular product development with Circularity and potential value capture indicators

de Pauw, I.C. (author), van der Grinten, B. (author), Flipsen, Bas (author), Alvarez Mendez, L.M. (author)

Most products require a redesign to be viable in a circular economy. For instance, by implementing design for disassembly, remanufacturing, recyclability, and using long-lived components. Typically, different solutions can be chosen to improve a products' circularity, and different strategies can be aimed at keeping the product, its components,...

Digital Government and the Circular Economy: Towards an Analytical Framework

Medaglia, Rony (author), Rukanova, B.D. (author), Tan, Y. (author)

Circular economy is high on the political agenda, with governments at all levels setting ambitious goals to move away from traditional linear production models, where goods are used and disposed as waste, towards a future with less use of virgin raw materials, and where valuable materials at a product end-of-life are returned as raw materials or...
