Reducing the Environmental Impact of Syringes at the Intensive Care Unit

This research project, part of the Green Intensive Care Unit (ICU) initiative at the Erasmus University Medical Center (EMC), is focused on reducing the environmental impact of syringes at the ICU by designing solutions based on circular economy principles. Based on a Material Flow Analysis of the EMC ICU, syringes and their packaging have been...

Circular applications through selection strategies (CATSS): A methodology for identifying reuse applications for end-of-life wind turbine blades

Wind turbines are crucial for the energy transition, but their end-of-life treatment presents a challenge. Most wind turbine blades, made from composites, are currently sent for disposal or recycled through methods that degrade the value of the material. Structural reuse through blade segmentation was introduced as a recovery method that...

Feasibility of On-demand Additive Manufacturing of Spare Parts

Spare parts availability is crucial for extending the life of consumer products. However, long-term availability could lead to high stocks of spare parts, which might not be used. Instead, on-demand manufacturing of spare parts with additive manufacturing (AM) is a promising alternative. This paper presents a method to evaluate parts on their...

Bio-based plastics in durable applications: The future of sustainable product design? A design review

This design review evaluates the use of bio-based plastics in durable consumer products. The main question is: how does the use of bio-based plastics influence the product’s design, functionality, marketing & communication, and sustainability? Although higher material prices would lead one to expect that higher value applications would be...

Circular Design of Composite Products: A Preliminary Framework Based on Insights from Literature and Industry

Composite materials are an attractive material choice as they enable lightweight, low maintenance products with a long lifespan. But closing the loop for these materials in a Circular Economy (CE) is challenging, especially for thermoset composites. In a CE, products should be designed for minimal impact while preserving their environmental and...

Design competencies for a circular economy

Limited research has been done on design competencies for a circular economy in practice. Yet, an overview of design competencies for a circular economy would be useful to understand which topics should be emphasized in both education and practice. This paper focuses on deriving circular economy competencies for product designers working in...

Annotated Portfolios as a Method to Analyse Interviews

This paper explores the use of annotated portfolios as a method to support the qualitative analysis of interview data about design projects. Annotated portfolios have so far been used to support artefacts with text in order to discuss them in the context of ‘research through design’ In this paper, we interpret the five-step method of McCracken...

Capabilities required to tackle barriers to remanufacturing

The transition towards a circular economy proposes to deliver sustainable, lower carbon opportunities to society, governments and companies. This paper focuses on finding barriers encountered during remanufacturing activities and interpreting the barriers by using a framework for dynamic capabilities. Dynamic capabilities enable companies to...

Is there a market for refurbished toothbrushes?: An exploratory study on consumers' acceptance of refurbishment for different product categories

Refurbishment is the process of collecting used products, assessing their condition, and replacing and/or upgrading parts in order to resell them to other consumers. Although refurbishment is increasingly seen as both economically and environmentally advantageous, it remains questionable whether consumers will accept refurbishment as a viable...

The role of product designers in the transition towards the circular economy: A reality check

This paper examines the role of product designers in the transition towards the circular economy. Both scientific and grey literature show remarkable optimism when it comes to role strategic and coordinating role designers could play in this transition process. However, there has been little examination of the actual role and influence designers...

Additive manufacturing for circular product design: A literature review from a design perspective

Circular product design is a relatively new approach to design suitable strategies to realize circular products. Additive manufacturing (AM) is seen as a promising enabling production process. It has digital and additive characteristics, which makes AM different from conventional production techniques. However, it is yet unclear how this...

Developments and challenges in design for sustainability of electronics

Sustainability of electronic products until recently mainly focused on improving the energy efficiency. Recently, resource efficiency has become of growing importance. Due to the use of relatively small amounts of many valuable and scarce materials, often intimately mixed, the design of electronic products deserves specific attention. From a...

Greenelec: Product design linked to recycling

GreenElec aims to significantly improve on the resource efficiency of electronics and electronic products. This is accomplished by close cooperation between manufacturers and recyclers. Design guidelines for improved recycling have been formulated and products (lamps and displays) have been redesigned according to these guidelines. Interestingly...
