Mobile phones are one of the most ubiquitous devices in our lives. The ever-growing demand for mobile phones and rapid upgrade patterns, gives mobile phones an unsustainable linear character, with a big contribution to e-waste. This study is about stimulating consumers to return their mobile phones to extend its life or fulfill another purpose through refurbishment and recycling processes. This project is conducted for the case of KPN’s return program and aims towards a beneficial exchange between KPN and consumer. Beneficial transactions of resources, already take place for millions of years in nature, where designers can learn and derive inspirations from. Therefore, these are explored and used as an inspiration throughout this project. Simultaneously an analysis of the mobile phone ecosystem is done to understand how and why retailers and consumers behave in the current context. An in-depth study with consumers resulted in insights on the impact of factors on current take-back programs. Next, to financial incentives, family friendly practice and charitable/circular motives are identified as incentives during the end-of-use stage. Users need to be informed well on the importance of the return of phones, the ease of the method and their privacy. Also, the perceived value of payback should exceed the perceived financial, functional and sentimental value in old phones and the perception of effort. This requires the elimination of negative factors and enhanced benefits for both KPN and consumer in their cooperation. The insights enabled the generation of relevant elements in nature and a translation onto the case. Based on the insights the design goal is formulated: a satisfactory disposal phase that ensures an alternative and long-term payback method for both KPN and users, that enables the involvement of other users for the spread of circular behaviour. As a result, KPN Bewust is developed: a return system that promotes the spread of information and circular behaviour through its return service. In this system, returning an old phone and involving others, is the by-effect of purchasing the next contract with or without a phone with discounts, which reduces the perceived effort. Persuading friends and family to return their phones, is rewarded with mutual benefits. These generous offers will give KPN a competitive advantage compared to traditional take-back programs, with more longterm and satisfied clients in return. Through the KPN Bewust profile, an overview of the generated discounts, and contacts shows how the advantages of a returned phone can outweigh the advantages of keeping them. This experience will increase the likelihood of repetition and the spread of return behaviour.

This report provides an analysis of the consumer experience at the end-of-use phase of a product. The study in this report focussed on the consumer-product relationship: how this plays a role in the process of product detachment, and what this means for products at the end-of-use, with a specific attention for products in a circular economy.
This end-of-use phase has been analysed with the goal of creating a design tool that enables industrial design students to design for the end-of-use consumer experience.

A theoretical framework of detachment is developed that shows the process of consumers when wanting to detach themselves from their possession. This framework is based on the works of Roster (2001) and Türe (2014). The detachment process consists of two parts: (1) dispossession, which is the mental process of distancing yourself from the product, and (2) separation, which is the physical act of removing the product from your life.
During the dispossession process, the consumer evaluates the product on what it is still worth to him and shows a dispossession behaviour to enable himself for physical separation.

To be able to design for the end-of-use experience, designers need to comprehend the detachment process, the consequences of the dispossession behaviours and need to be able to apply this knowledge into designing an end-of-use experience.

The developed design tool enables design students to analyse the detachment process with the use of consumer-product lifecycle, and recognize where opportunities lie for an end-of-use experience by reflecting on the lifecycle and defining a design goal, concluding the analysis. The tool will be used in a workshop context, where the students are introduced to the concept of detachment and the consumer experiences at the end-of-use. They are supported to find opportunities for which they could design a new end-of-use experience that stimulates their consumer to keep their product in the circular loop.

The dispenser project focused on developing an external vision for a dispenser range for the future washroom in office buildings, retirement homes, and hotels. The project resulted in a foldable dispenser that reduces sustainable impact by decreasing its volume during transport. Another part was wrapping the dispenser to let end customers be able to personalize it and let it fit within every washroom. This result was achieved by combining the VIP process and CVD approach, implemented with a stipulated version of ZMET.

The reduction of waste materials is an important step towards a more circular economy. Within the mattress industry, the focus on sustainability and recycling has increased substantially over the last few years. In the Netherlands and a few other European countries the recycling of mattresses is strongly encouraged or made mandatory by local and national government.
Matras Recycling Europe B.V. is a Dutch company that specialises in the collection and disassembly of used mattresses. In order for this business to be viable and to increase the circularity of the entire mattress industry, it is important to find a suitable application for each of the materials of a used mattress. This thesis focuses on researching the potential of the outer layer of the mattress: mattress ticking.

This report describes the methods, outcomes and decisions that were made to create the final product. At the start of the project, the research question was:
“How can recycled ticking materials be used to design pet products, in the most sustainable way?”

The Material Driven Design method (Karana et al., 2015) was applied as a framework to determine the properties of the material, determining the market opportunities for mattress ticking.
Focus groups with the target group resulted in insights, which in combination with interviews with experts and other research, resulted into a preliminary list of requirements where the product should abide by.
After exploring multiple search areas, the search area “Travelling with dogs” was chosen because of the high viability. This search area led to 17 ideas, which were scored using the Harris profile method.
After further elaboration of the three concepts (Fence, Sunshade and Hammock) that scored best, one concept was chosen because it had the highest viability and desirability. This concept (Fence) was developed into the final product: Dipi. Dipi is a simple dog tent that protects dogs from the sun and creates a secluded area for the dog to lay in. The product is lightweight and easy to use. The product is intended to bring along on holiday.
The launch of the product is supported by a marketing strategy and a list of potential production partners, that is proposed to the client company.
After materialising the final design of the product, a prototype was made. The final prototype was tested in an exploratory user test with the envisioned target group, after which final design recommendations were set up.
The thesis is concluded with further recommendation for developing the Dipi and an extensive evaluation of the used methods during the project.

Low and Middle Income Countries (LMICs) face major issues throughout the continuum of primary healthcare for child care (0-5 years). Altogether more than 10 million children die each year in developing countries before they reach their fifth birthday. WHO and UNICEF created an Integrated Management of Childhood Illness (IMCI) strategy to tackle this global issue. This design aims to improve the usability and scalability of this strategy at user level across India and Kenya.

Context Variation by Design approach is used to focus on usability and scalability. In this approach, insights from different contexts are studied to find shared or opposing requirements.

The product consists of a diagnostic device with a capability of providing four diagnostic information within the IMCI workflow. The product is designed to be scalable across various users with varying expertise and geographical contexts of India and Kenya.
