European clothing consumption has increased dramatically in recent decades, leading to a current average of 26 kg of textiles annually purchased per capita (EEA, 2019). While garments (and most of clothing’s environmental impacts) are produced in other parts of the world, European municipalities face a problem of increasing volumes of textile waste. Moreover, the revised waste directive of 2018 specifies that European Union countries will be obliged to collect textiles separately by 2025. This study investigates how these phenomena are affecting city-level policy and strategy, including but not limited to textile waste management. It builds on a comparative analysis of official documents informed by interviews with policy makers and waste management authorities in five European cities. The research points out that, in these cities, clothing environmental policy and other public initiatives are at varied levels of development. The paper identifies three kinds of measures, namely (a) improving separate collection, (b) waste prevention, and (c) consumption reduction. Reducing the share of textiles disposed of in general household waste (and therefore increasing separate collection) has been a central aim in cities where textiles fall under local waste regulation. The waste directive mentioned above makes separate collection of all textiles compulsory for EU members, leading to revisions in some cities’ collection systems. Some municipalities have gone one step further in preventing these textiles from reaching waste streams by supporting local initiatives for repair and reuse. The most advanced and recent approach is aiming at reductions in new clothing demand through citizen campaigns and monitoring the effect of repair and reuse actions in consumption levels. The comparative analysis leads to recommendations for future policy and strategy including developing the three approaches mentioned above simultaneously, further exploring measures for consumption reduction, and the integration of more concrete targets and monitoring plans, so that the most effective paths in social and environmental terms can be identified.
Many interesting smart textile concepts have been developed, however there are only a few relevant examples of concepts that are producible and valuable for our society. The so-called ‘killer application’ has not been found yet. That is why it is extremely important that multi-disciplinary parties team-up during the ideation process to come up with innovative solutions (Toeters, 2007). The goal of STS CRISP (Crisp, 2011) is to integrate existing knowledge from partners in the separate domains of textile (soft materials), technology and service providers. To investigate the different kinds of expertise necessary for the development of Smart Textile Services we initiated an assignment to develop new Smart Textile Services concepts for elderly that can be used during rehabilitation (ten Bhömer, Tomico, Kleinsmann, Kuusk & Wensveen, 2012) and executed this project in 2 different institutes: Saxion University of Applied Sciences and Eindhoven University of Technology (TU/e). Through some pre-set contact moments, the use of a gatekeeper (Vertooren, 2007) active in both institutes, and analyzing the final reports we are able to acquire an insight in the different approaches and focus preferences of the institutes. The analysis lead to the following observations: 1. Saxion students spend more time researching existing technologies and how to implement them in their concepts. A more theoretical approach from what is already there, applying existing materials and opportunities that are already there. 2. The TU/e students consistently focused on on user research to find out their perspectives. More user-centered. 3. Saxion students start with ideation and validate this by analyzing what is available in the market at the beginning of the process. 4. TU/e students work from a societal perspective towards user focus and an idea. TU/e students found out that there is a lot more steps after prototyping. Saxion takes the next step: where TU/e students stop, they continue. Out of these observations we can conclude that the institutes are active on different levels on the time-to-market line. We have to take into account that every collaborator has a different time-to-market horizon. For the STS CRISP consortium this means that efforts have to be made to define the time-to-market expertise of the partners. As a next step, we will continue to explore this concept of parallel collaboration assignments and start a new collaboration assignment in sequence in different institutes. Test the time-to-market approach and gather strategies to create a more in depth approach to relevant marketable products can speed up the process of bringing concepts to the market, so that it can have a true added value for society.

Despite the recognized benefits of running for promoting overall health, its widespread adoption faces a significant challenge due to high injury rates. In 2022, runners reported 660,000 injuries, constituting 13% of the total 5.1 million sports-related injuries in the Netherlands. This translates to a disturbing average of 5.5 injuries per 1,000 hours of running, significantly higher than other sports such as fitness (1.5 injuries per 1,000 hours). Moreover, running serves as the foundation of locomotion in various sports. This emphasizes the need for targeted injury prevention strategies and rehabilitation measures. Recognizing this social issue, wearable technologies have the potential to improve motor learning, reduce injury risks, and optimize overall running performance. However, unlocking their full potential requires a nuanced understanding of the information conveyed to runners. To address this, a collaborative project merges Movella’s motion capture technology with Saxion’s expertise in e-textiles and user-centered design. The result is the development of a smart garment with accurate motion capture technology and personalized haptic feedback. By integrating both sensor and actuator technology, feedback can be provided to communicate effective risks and intuitive directional information from a user-centered perspective, leaving visual and auditory cues available for other tasks. This exploratory project aims to prioritize wearability by focusing on robust sensor and actuator fixation, a suitable vibration intensity and responsiveness of the system. The developed prototype is used to identify appropriate body locations for vibrotactile stimulation, refine running styles and to design effective vibration patterns with the overarching objective to promote motor learning and reduce the risk of injuries. Ultimately, this collaboration aims to drive innovation in sports and health technology across different athletic disciplines and rehabilitation settings.
In Europe nearly 10% of the population suffers from diabetes and almost 1% from Rheumatoid Arthritis which can lead to serious problems with mobility and active participation, especially in the ageing population. Pedorthists deliver personalised designed and manufactured orthopaedic footwear or insoles for these patients. However, despite their often laborious efforts upfront, the industry has very little means to quantify how successful the fitting and function of a shoe is. They have to rely on subjective, qualitative measures such as client satisfaction and diminishing of complaints. Although valuable, the need for objective quantitative data in this field is growing. Foot plantar pressure and shear forces are considered major indicators of potential foot problems. Devices to measure plantar pressure slowly gain terrain as providers of objective quantitative data to guide orthotic design and manufacturing. For shear forces however, measuring devices are not yet commercial available. Although shear forces are considered as a major contributor to ulcer formation in diabetic feet, their exact role still requires elucidation and quantification. This project aims to develop a prototype of an in-shoe wearable device that measures both shear forces and pressure using state-of-the-art developments in sensor technologies, smart textiles and wireless data transfer. The collaboration of pedorthists’ small and medium-sized enterprises (SME)’s with medical device engineering companies, knowledge institutes,technical universities and universities of applied sciences in this project will bring together the different fields of expertise required to create an innovative device. It is expected that the tool will be beneficial to improve the quality of pedorthists’ services and potentially reduce health insurance costs. Furthermore, it can be used in new shear forces research and open new business potential. However, the eventual aim is to improve patient care and help maintain personal mobility and participation in society.
