Sustainable behavior change towards short-haul flights for business trips: Applying the Fogg Behavior Model to determine how to change the mindset towards flying for business with the aim to reduce the impact of flying

Companies let their employees take short-haul flights for business trips while there are alternative, more sustainable, modes of transport. Understanding the motivation of the company and their employees for flying is essential to create a design solution which could change their behavior. To reach the goal of a maximum global temperature rise...

Creating transparency and guidance in Circular Economy indicators: Tools for assisting circular consultants with choosing the right CE indicators for manufacturing companies

Businesses are being increasingly pressured to start making the transition from their current polluting economy towards a circular economy (CE) to pursuit a sustainable industry. Indicators for CE play a key role in this transition, enabling the measurement and control of this development. However, the scattered landscape of micro level CE...

3D Printing of Large Objects with PET Flakes

“3D Printing of Large Objects with PET Flakes” is the Graduation project of Daniël Eikelenboom of the Faculty of Industrial Design Engineering of the TU Delft for the Rotterdam based company 3D Robotprinting. The project focusses on the development and implementation of an ‘all-inclusive’ PET bottle recycling unit containing a large-scale 3D...

Repairable smartphones: Developing a Product-Service System that stimulates consumers to choose for repair over replacement

The increasing global need for environmental preservation calls for new methods to increase the material efficiency of products. One way to do this, is by extending the use cycle of a product, by making the product more repairable. This thesis has studied existing use cycle extension strategies to propose a new smartphone ProductService System...

Circularity in the Dutch train

This graduation project makes a contribution to this complex challenge by researching the question “How can NS achieve circular inflow and outflow during building, modernisation and end-of-life for the train interior, car body and bogies?”. A contribution to this challenge was made by creating a design concept for a sustainable interior side...

Repairability of lattice structure in a circular economy: Mechanical response of 3D printed octet-truss lattice structures under quasi-static loading

Repair and maintenance of products require few resources in a circular economy, minimising the environmental impact of manufacturing and use of products. Although lightweight lattice structures have been widely investigated in various fields owing to their advantages in terms of their mechanical characteristics and the development of additive...
