Network Applied Design Research (NADR) made an inventory of the current state of Circular Design Research in the Netherlands. In this publication, readers will find a summary of six promising ‘gateways to circularity’ that may serve as entry points for future research initiatives. These six gateways are: Looped Systems; Extension of Useful Lifetime; Servitisation; New Materials and Production Techniques; Information Technology and Digitization; and Creating Public and Industry Awareness. The final chapter offers an outlook into topics that require more profound examination. The NADR hopes that this publication will serve as a starting point for discussions among designers, entrepreneurs, and researchers, with the goal of initiating future collaborative projects. It is the NADR's belief that only through intensive international cooperation, we can contribute to the realization of a sustainable, circular, and habitable world.
This communication aims to provide a framework on how to integrate the concept of Circular Economy (CE) when addressing real-life urban challenges such as resource scarcity, greenhouse gas emissions, pollution, waste, and high consumerism (Williams, 2019), through delivery of courses to students of various educational backgrounds. As part of the mission of Amsterdam University of Applied Sciences (AUAS) to be at the forefront of promoting sustainability through education and research, the Faculties of Technology and of Business and Economics joined forces to launch a new minor namely Circular Amsterdam: Mission Zero Waste. This minor focuses on the challenges and opportunities towards the circular transition in Amsterdam as well as in other European cities, by applying system level of thinking and real-life practical cases.CE model is a shift from the traditional linear “take, make, and dispose” way of doing business, to promoting circularity of the waste product through the 3R principles (reduce, reuse, recycle), which is nowadays extended to using 9R principles (0-Refuse, 1-Rethink, 2-Reduce, 3-Reuse, 4-Repair, 5-Refurbish, 6-Remanufacture, 7-Repurpose, 8-Recycle, and 9-Recover) (Potting et al., 2017). Transitioning to CE model needs intervention and multidisciplinary approach at different levels, hence requiring systems level of thinking. This means that technical, organizational, economic, behavioral, and regulatory aspects should be taken into account when designing business models, policies, or framework on CE. In the case of the minor, a system change including the challenges and opportunities needed in the cities, will be approached from different perspectives. In order to do this, the minor requires collaboration on a real-life problem using multiple backgrounds of students that include technical, economic, creative and social domains, as well as various stakeholders such as businesses, policy makers, and experts in circular economy.This minor will provide in-depth knowledge and skills based on its two tracks. The first track is called Circular Design & Technology. It focuses on the role of technology in CE, technological design, material use, production, use of circular resources in production, and impact analysis. The second track is called Circular Governance & Management. This track focuses on viable business case development, circular supply chain management, finance, regulations, entrepreneurship, and human capital. The focus of this communication will be the second track.Multidisciplinary teams each consisting of approximately four students will work on different projects. Examples of real-world, practical cases related to Circular Governance & Management track include: (1) development of business models addressing resource shortages and waste in the cities, (2) influencing consumer mindset when it comes to recycling and use of circular materials and products, (3) development of financially viable circular businesses, with due consideration of different instruments such as traditional bank loans, green/social bonds and loans, crowdfunding, or impact investing, and (4) tracking and reporting their sustainability performance with the voluntary use of sustainability metrics and reporting standards in order to better manage their risk and attract capital. These projects are linked to research expertises in AUAS. The course activities include (guest) lectures, workshops, co-creation sessions, excursions, presentations and peer reviews. The learning goals in the Circular Governance & Management track include being able to:1. Understand the foundations of CE and theory of change;2. Apply systems thinking to show how different interventions, such as consumer products, logistics models, business models or policy designs, can affect the transition from the existing linear to a CE model;3. Design an intervention, such as a product, logistic concept, business model, communication strategy or policy design supporting the CE, using students‘ backgrounds, ambitions and interests;4. Understand the financial and regulatory framework affecting the management and governance of (financially viable) circular businesses, including government incentives;5. Evaluate the economic, environmental and social impacts of developed intervention design on the city and its environment;6. Provide justification of students‘ design according to sustainability performance indicators;7. Collaborate with stakeholders in a multidisciplinary team; and8. Present, defend and communicate the results in English.
Recycling of plastics plays an important role to reach a climate neutral industry. To come to a sustainable circular use of materials, it is important that recycled plastics can be used for comparable (or ugraded) applications as their original use. QuinLyte innovated a material that can reach this goal. SmartAgain® is a material that is obtained by recycling of high-barrier multilayer films and which maintains its properties after mechanical recycling. It opens the door for many applications, of which the production of a scoliosis brace is a typical example from the medical field. Scoliosis is a sideways curvature of the spine and wearing an orthopedic brace is the common non-invasive treatment to reduce the likelihood of spinal fusion surgery later. The traditional way to make such brace is inaccurate, messy, time- and money-consuming. Because of its nearly unlimited design freedom, 3D FDM-printing is regarded as the ultimate sustainable technique for producing such brace. From a materials point of view, SmartAgain® has the good fit with the mechanical property requirements of scoliosis braces. However, its fast crystallization rate often plays against the FDM-printing process, for example can cause poor layer-layer adhesion. Only when this problem is solved, a reliable brace which is strong, tough, and light weight could be printed via FDM-printing. Zuyd University of Applied Science has, in close collaboration with Maastricht University, built thorough knowledge on tuning crystallization kinetics with the temperature development during printing, resulting in printed products with improved layer-layer adhesion. Because of this knowledge and experience on developing materials for 3D printing, QuinLyte contacted Zuyd to develop a strategy for printing a wearable scoliosis brace of SmartAgain®. In the future a range of other tailor-made products can be envisioned. Thus, the project is in line with the GoChem-themes: raw materials from recycling, 3D printing and upcycling.
The increasing amount of electronic waste (e-waste) urgently requires the use of innovative solutions within the circular economy models in this industry. Sorting of e-waste in a proper manner are essential for the recovery of valuable materials and minimizing environmental problems. The conventional e-waste sorting models are time-consuming processes, which involve laborious manual classification of complex and diverse electronic components. Moreover, the sector is lacking in skilled labor, thus making automation in sorting procedures is an urgent necessity. The project “AdapSort: Adaptive AI for Sorting E-Waste” aims to develop an adaptable AI-based system for optimal and efficient e-waste sorting. The project combines deep learning object detection algorithms with open-world vision-language models to enable adaptive AI models that incorporate operator feedback as part of a continuous learning process. The project initiates with problem analysis, including use case definition, requirement specification, and collection of labeled image data. AI models will be trained and deployed on edge devices for real-time sorting and scalability. Then, the feasibility of developing adaptive AI models that capture the state-of-the-art open-world vision-language models will be investigated. The human-in-the-loop learning is an important feature of this phase, wherein the user is enabled to provide ongoing feedback about how to refine the model further. An interface will be constructed to enable human intervention to facilitate real-time improvement of classification accuracy and sorting of different items. Finally, the project will deliver a proof of concept for the AI-based sorter, validated through selected use cases in collaboration with industrial partners. By integrating AI with human feedback, this project aims to facilitate e-waste management and serve as a foundation for larger projects.
By transitioning from a fossil-based economy to a circular and bio-based economy, the industry has an opportunity to reduce its overall CO2 emission. Necessary conditions for effective and significant reductions of CO2-emissions are that effective processing routes are developed that make the available carbon in the renewable sources accessible at an acceptable price and in process chains that produce valuable products that may replace fossil based products. To match the growing industrial carbon demand with sufficient carbon sources, all available circular, and renewable feedstock sources must be considered. A major challenge for greening chemistry is to find suitable sustainable carbon that is not fossil (petroleum, natural gas, coal), but also does not compete with the food or feed demand. Therefore, in this proposal, we omit the use of first generation substrates such as sugary crops (sugar beets), or starch-containing biomasses (maize, cereals).
