Designing and realizing circular urban road renovation

The built environment rapidly needs to become more sustainable. The municipality of Apeldoorn is also aware of this. There, the need for new resources needs to be reduced and the resources themselves need to be renewable. In other words, material loops need to be closed. We are looking for innovative, smart and assertive students, eager to conduct a study and willing to design new circular processes for the road industry. Can you find out what the residents of De Maten in Apeldoorn would like to see and what they would like to have in their street? Can you re-organize the public space with circular materials? Are you interested in materials needed in products that shape that public space and that make up our roads? Then we would like to have you in our team to design and to facilitate the realization of urban road renovation projects circularly.

Re-use our textile cutting waste into acoustic screens

Ahrend is a designer and supplier  for office furniture an interiors. To do this, they do not only supply their own products, but also products of third parties such as furniture, flooring, lighting and art, etc. Ahrend is a leading C2C company in its industry and has been viewing the circular economy for years as an opportunity to achieve better products for customers and the environment. The development also continues in the development of services such as lease (Ahrend Furniture as a Service), re-use (Ahrend Reuse) and public-private partnerships, in which the use of office space is facilitated for a longer period of time. Ahrend not only wants to facilitate the customer with beautiful and sustainable circular products and services, but also to reduce the operational costs for our customers as much as possible over more than one lifetime. In recent years, the circular economy has attracted increasing attention. Ahrend has been the only C2C company in its industry. The development of sustainable products is in its genes. Responsible materials and processes are used, but we still have some problems to solve. One of them is to use our textile cutting waste (and the textile waste of customers) for our products. The cutting processes are highly efficient, but unfortunatly cutting waste is inevitable. Thats why we still have 1300 kilograms of textile cutting waste each week. We would like to use this textile for screens wich we can use to provide acoustic comfort for our customers. These acoustic screens, made out of re-used feld and fibers, allow employees to better concentrate on their work. Our questions are: how can we do this specificly, what is the break even point, what should the business case look like, and what should we do to make this new loop a success! We not only want to develop a circular acoustic screen with a beautiful design, but also a screen with better acoustic properties in the low frequency areas (speech). So, we need acoustic insights and knowledge to develop a construction which meets these requirements. With this knowledge in mind, you will need to develop an acoustic package, probably composed of multiple layers with specific acoustic properties, to absorb sound over a broad spectrum, which is important for a better working environment in offices. These requirements are also likely to define the properties and production method required for the different layers of the acoustic package.

Product development based on biodegradable mycelium (fungal threads of a mushroom)

ma.c. Ellen is a startup that focuses on the applications of mycelium grown on biodegradable raw materials. ma.c Ellen developed from practice. Through trial and error, we work in a process-oriented way on the development of products with a high design value & semi-finished products for designers and makers. ma.c Ellen wants to contribute to the development of a bio-based and circular economy. Inspiring and working together with creative and sustainable entrepreneurs is the starting point, where ma.c Ellen dreams of a creative incubator in Deventer (similar to Blue city in Rotterdam). The project will look at the process of mycelium growth, the production of materials (like vegan leather) and products, but also the business, communication and marketing aspects.

AlarmPhaseN! – Circular agriculture in Twente by natural fertilizers

Our national economy is on-hold due to the ammonium and nitrogenoxydes emissions of our agriculture, our traffic, or in general many economic activities. Although Dutch agriculture is world-famous concerning its high efficiency (we are as very small country the 2nd large producer of food worldwide), we are becomimg victim of our own success! Time for action and more steps towards circular economy! Intensive livestock farming has led to over-fertilization of agricultural land, resulting in environmental problems due to phosphate(P) and nitrogen (N) leaching to ground and surface waters. Dutch government prevents further accumulation of P in the soils setting limits to the P-content of fertilizers. As a consequence, a large fraction of the P-rich manure cannot be used to fertilize the Dutch soils and is exported abroad, while artificial fertilizers are being imported, leading to the paradoxical situation in which farmers pay to get rid of their manure and meanwhile purchase mineral N-fertilizers to fertilize the soil. Digestion of the manure produces biogas, but getting rid off the remaining digestate reduces the profit enormously and hinders the goal to make our agriculture circularly. The liquid fraction of the digestate, however, contains N and Kalium (K) that would be very valuable for farmers, if concentrated and separated, so it can be applied as natural fertilizer to prevent the purchase of artificial fertilizers. In cooperation with our project partners, a concept has been developed in which several membrane process play an important role. The total concept is currently as demo plant under operation and shows very promising results for the separation and concentration of N and K. However, many questions are still open which require additional investigation. We will focus on the biological and chemical fouling mechanisms of the membranes; the sedimentation of different, sometimes unidentified, chemical species; and optimization of the process. Furthermore, we want identify the economical potential for Twente of this new concept which not only valorize the biogas, but also the resulting digestate as high quality natural fertilizer. Finally, we want to investigate what are the biological and chemical (growth) potentials of this natural fertilizers. In short, we are looking for ambitious developers and entrepreneurs for a circular agriculture in Twente!

Circular Textile Information Platform

Saxion is part of the TexPlus Foundation, which is a collaboration of different textile companies in Twente. With the support of the RegioDeal project the Saxion research group Sustainable & Functional Textiles is working on making Twente the center for the circular textile supply chain. The consumption of textiles has a big impact on the environment. To obtain a circular textile supply chain the recycling of textiles is necessary. One of the challenges in this circular supply chain is the match of supply and demand. There is little to no connection between textile recyclers and companies that have a specific textile waste stream. A platform that summarises all recycling initiatives and provides the user with the most recent information about textile recycling would increase the material flow in a circular economy for textiles. Assignment: the goal of the platform is to inform companies about recycling technologies and help close the circular supply chain. Additionally, research should be done on practical aspects of the website such as who should monitor the platform and how to validate the information that is shared on the platform. Furthermore the platform can be expanded with a section for information sharing, regarding the processing of textile waste. This project will be a continuation of a previous project, in which students came up with a concept for a circular textile platform. The created prototype of the platform should be further developed into an actual online platform, which includes the most recent information about textile recycling.
