From 2015 till present, the Professorship for Polymer Engineering has developed the principle of structural re-use of End-of-Life (EoL) thermoset composite products. The method is based on keeping the composite structure of EoL products but machining them into smaller parts, either strips or flakes, …

The aim of this research was to find out in how far the Netherlands could learn from Sweden regarding the use of manure, in order to create awareness within the equine sector on sustainable solutions. The number of horses in Europe exceeds 5 million and keeps increasing, therefore contributes to greenhouse …

Lupinus mutabilis is an important source of protein in different Andean countries, and its use in diets, particularly those of less wealthy individuals, has been observed for thousands of years. There is an increasing demand for protein crops suitable for Europe and this species is a potential candidate. …

The goal of this research was to set up suitable laboratory tests and analysis methods for the strength and durability testing of bio-based textile reinforced concrete. This thesis was a preparatory research for the actual development of bio-based TRC applications, which was not undertaken due to unforeseen …

One of the recent developments in the aerospace industry is the use of thermoplastic composites. Thermoplastic composites can be welded instead of using other bonding techniques. One of the welding techniques is induction welding. Induction welded parts are already used in aerospace applications, yet …

Our planet’s ecology and society are on a collision course, which manifests due to a contradiction in the assumptions of unlimited material growth fueling the linear economic paradigm. Our closed planetary ecosystem imposes confined amounts of space and a finite extent of resources upon its inhabitants. …

This paper addresses the design dilemmas that arise when distributed ledger technologies (DLT) are to be applied in the governance of artificial material commons. DLTs, such as blockchain, are often presented as enabling technologies for self-governing communities, provided by their consensus mechanisms, …

The concept of green biorefinery is based on the processing of green biomass into range of innovative products. The basic idea is to use the green biomass in the most optimal way to produce energy and marketable products. Grass silage has versatile properties as raw material for green biorefinery with …

The potential of software tools to support learning mathematics is widely acknowledged, but their use can be hindered for many reasons. When teaching future mathematics teachers, we observed that these students were unmotivated to use such tools. This lack of motivation was caused by two concerns held …

In our in-depth case study on two circular business models we found important roles for material scouts and networks. These key partners are essential for establishing circular business models and circular flow of materials. Besides, we diagnose that companies are having difficulties to develop viable …
