Bio-Based Plastics in Product Design: The State of the Art and Challenges to Overcome

Replacing fossil-based feedstock with renewable alternatives is a crucial step towards a circular economy. The bio-based plastics currently on the market are predominantly used in single-use applications, with remarkably limited uptake in durable products. This study explores the current state of the art of bio-based plastic use in durable...

A novel suspended microchannel resonator design with a high Qf product

Suspended microchannel resonators are a kind of mechanical resonator with an embedded microchannel inside. This is done as for some samples it is convenient or even necessary to put the sample into a fluid. The sample can then travel through the channel and its mass can be determined. The channel also simplifies placement of the samples compared...

The Impact of Co-Creation on the Design of Circular Product-Service Systems: Learnings from a Case Study with Washing Machines

Designers play an important role in service transformation and the development of product-service systems by applying co-creation methods. This paper presents a case of how we applied co-creation in practice and the impact this has had on developing a circular product-service system. It details the method used in the co-creation process and...

How to visualize recorded production data in Virtual Reality? How to use state of the art Augmented Reality displays that can show robot data? This paper introduces an opensource ICT framework approach for combining Unity-based Mixed Reality applications with robotic production equipment using ROS Industrial. This publication gives details on...

Co-creating circular product-service systems for long-lasting washing machines

This paper presents the result of a co-creation and context mapping study amongst seventeen washing machines users. The users had widely varying experiences with products offered through alternative ownership models, including three who were active users of a washing machine with pay-per-use or monthly subscription model. Through the co-creation...

ResCoM Design Methodology for Multiple Lifecycle Products

By combining the lessons learned from the four ResCoM industrial cases, a generic methodology was developed for other companies that want to engage in the development of multiple-lifecycle products. This report describes a stepwise approach for developing such products. The approach includes a suite of design tools as well as a practical case...

The circular pathfinder: Development and evaluation of a practice-based tool for selecting circular design strategies

The Circular Pathfinder tool, which provides guidance to companies looking for appropriate circular design strategies, was developed based on OEM (original equipment manufacturer) case studies. Ease of use was one of the main requirements during development of the tool, resulting in a software-based guide that asks a maximum of ten product...
