Chalmers, together with the University of Cambridge and Fraunhofer FCC, is leading a project that studies aspects of manufacturing during the design phase.</b></p><p></p> <div>The next generation of aircraft engines is being developed in the large European project <a href="">Clean Sky 2</a>. Open Rotor is one of the concepts that has shown promising results when it comes to reducing both CO<sub>2</sub> emissions and noise. Open rotor is a new engine type with two, counterrotating, propellers that radically improve propulsive efficiency. This type of technology radically changes how the engines are designed and integrated with the aircraft. </div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/IMS/Produktutveckling/Open%20Rotor%203%20-®%20Eric%20Drouin%20Safran_400px.jpg" alt="Open Rotor 3 -® Eric Drouin Safran" class="chalmersPosition-FloatLeft" style="margin:5px 15px;width:170px;height:259px" />Within Clean Sky 2, Chalmers, together with Cambridge University and Fraunhofer FCC, is now leading a project called Development of Interdisciplinary Assessment for Manufacturing and Design (DIAS).<br /><br />DIAS is a targeted support project, where the goal is to develop support for integrating manufacturability aspects already in the design phase, where advanced decision support models are developed. For example, it is critical that robots get to weld the components properly. In the DIAS project, Chalmers latest research results are used in modeling alternative concepts enabling digital experimentation of alternative product architecture, with Fraunhofer's expertise in simulating robotic paths, and Cambridge's expertise in interactive decision-making and modeling-based risk analysis.<br /><br /></div> <div><br /><em>–    We have a unique opportunity to combine the latest achievements from Chalmers, Fraunhofer FCC and Cambridge, into a new and powerful way to support GKN Aerospace in their integration of next generation technologies already in the concept phase, says Ola Isaksson, researcher at Chalmers and leader of the consortium.</em><br /><br />GKN Aerospace Sweden AB in Trollhättan is responsible for critical engine components of Open Rotor engines. Ultimately, the goal is to enable the methods developed in the DIAS project to enable GKN Aerospace to offer the technologies demonstrated in Clean Sky in future business.<br /> <br /><em>–    We are very happy that this Chalmers led consortium won this Call for Partners.

She started her work at the Department of Industrial and Materials Science this year and will be assisting CAM2&#39;s director Eduard Hryha.</b></p><p><span lang="EN-US"><b>Field of research</b></span><span lang="EN-US"><b>:</b> Additive manufacturing of nickel-based superalloys focusing on the relationship between microstructure and mechanical properties, mainly related to Centre for Additive Manufacture – Metal (CAM2).</span></p> <p><br /></p> <p><b>Give us a short info about you. How did your career start?</b></p> <p>“I grew up in the west of Germany. To explore more corners of the country, I took my BSc in the north, in <a href="">Bremen</a>, and did my course internship at <a href="">ZF Friedrichshafen</a> in the very south at Lake Constance. After that I moved to the point furthest away from any coast on the UK 'island' – as I was welcomed in my first lecture in Birmingham. Here, I discovered that both road cycling and rowing were excellent distractions from doing a PhD.&quot;​<br /></p> <p><br /></p> <p><b>What attracted you to Chalmers?</b></p> <p>&quot;As a University of Technology, Chalmers offers so much potential for research and learning, both in materials science and cross-collaborations. I specifically applied because working at <a href="/en/centres/cam2/Pages/default.aspx" title="link to CAM2 centre" target="_blank">CAM2​</a> is a great opportunity for me to explore metal additive manufacturing (AM), and the role basically described what I wanted to do – applied research!”</p> <p><br /></p> <p><b>What did you do before coming to Chalmers?</b></p> <p>“I did my PhD at the metallurgy and materials department at the <a href="">University of Birmingham</a>. My focus was on the relationship of microstructure and mechanical properties in a nickel superalloy in collaboration with Rolls Royce – not the cars but the aero engines! </p> <p>After that I joined <a href="">Materials Solutions</a> – a Siemens business where I discovered metal AM in an industrial and production environment. There I had the chance to gain experience across the entire manufacturing chain for an AM component. And while it certainly was a very challenging environment, I missed the research a little bit too much…and that’s how I landed here.”</p> <p><br /></p> <p><b>What type of challenges do you find most interesting / what kind of challenges do you foresee?</b></p> <p>“On a research level, one of the big challenges is to understand the microstructure and what it means for the material and component use. </p> <p>On a personal level, I find having multiple research projects going on at the same time both exciting and challenging – as was starting to learn Swedish…where do all those consonants go?!”</p> <p><br /></p> <p><b>How do you see your role as a key player in CAM2?</b></p> <p>“For one, I like being part of a team – and research is really a form of team sport! And considering that nickel superalloys are increasingly important for metal AM and will be a fixed part of its future, my background in these materials will be complementary to the research topics that are already being investigated at the centre. Having gained two years of industry experience also helps navigating the many collaborations between companies and CAM2 and I can offer a perspective on the industrial applications and expectations for metal AM.”</p> <p><br /></p> <p><b>What are you most passionate about in your research?</b></p> <p>“I am fascinated by the fact that the different aspects of microstructure can have such a huge effect on how you can use the material later. And additive manufacturing adds another level of complexity as  we’re still understanding how the processing parameters and post-processing procedures influence the material – AM microstructures can look completely different to what we’re used to from other manufacturing processes.”</p> <p></p> <p> </p> <p><b style="background-color:initial">AM is often mentioned together with sustainability. Can you see some extraordinary possibilities with the method?</b></p> <p>“I see the complete re-thinking of design (component design but also material dependent design)  as a possility. To make systems, like gas turbines for power generation more sustainable, they have to run more efficiently. Reducing weight through clever re-design, improving flowability through surface feature design, and producing near-net-shape parts made of difficult to manufacture high temperature materials are some of the many opportunities available through AM to achieve that.</p> <p><br /></p> <p><br /></p> <p>Read more about <a href="/en/Staff/Pages/sfion.aspx">Fiona Schulz</a></p> <p><a href="" target="_blank" title="link to film on youtube"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Film about her research at University of Birmingham </a></p> <p><br /></p> <p><span lang="EN-US"></span></p> <p>​​<br /></p>Thu, 25 Jun 2020 11:00:00 +0200 User Studies from Distance<p><b>​Due to the pandemic this spring, Chalmers Production Area of Advance are financing a couple of projects with the purpose to be better equipped for similar changes in the future.

A major problem is that recycled plastic can be unpredictable and of varying quality. Researchers at Chalmers will therefore study how to develop a more reliable and qualitative raw material from the recycled plastic.</b></p><div>The basic and first step in plastic recycling is the initial sorting. The more pollution and indigestible material that goes to the next step, the more expensive and more complicated it becomes to produce a raw material that can be used for new products.

Instead of finding companies that show a unique stock price over time compared to other stocks, the target is to identify machines that exhibit unique behavior as compared to other machines on the shop floor.</b></p><div>The unique behavior of those machines is a key indicator that they are bottlenecks. Curious to know how? Then check out our article! We explain the methodology based on unsupervised ML techniques, demonstrate it on two real production systems, and explain how the algorithmic insights can be consumed by engineers to augment their decisions on bottlenecks. Identifying the right bottlenecks help engineers make correct and more confident decisions to improve shop-floor productivity!</div> <div><br /></div> <div>The advancements in machine learning (ML) techniques open new opportunities for analysing production system dynamics and augmenting the domain expert's decision-making. A common problem for domain experts on the shop floor is detecting throughput bottlenecks, as they constrain the system throughput. Detecting throughput bottlenecks is necessary to prioritise maintenance and improvement actions and obtain greater system throughput. The existing literature provides many ways to detect bottlenecks from machine data, using statistical-based approaches. These statistical-based approaches can be best applied in environments where the statistical descriptors of machine data (such as the distribution of machine data, correlations, and stationarity) are known beforehand. Computing statistical descriptors involve statistical assumptions. When the machine data doesn't comply with these assumptions, there is a risk of the results being disconnected from actual production system dynamics. An alternative approach to detecting throughput bottlenecks is to use ML-based techniques. These techniques, particularly unsupervised ML techniques, require no prior statistical information on machine data. </div> <div><br /></div> <div>This paper proposes a generic, unsupervised ML-based hierarchical clustering approach to detect throughput bottlenecks. The proposed approach is the outcome of a systematic and careful selection of ML techniques. It begins by generating a time series of the chosen bottleneck detection metric and then clustering the time series using a dynamic time-wrapping measure and a complete-linkage agglomerative hierarchical clustering technique. The results are clusters of machines with similar production dynamic profiles, revealed from the historical data and enabling the detection of bottlenecks. The proposed approach is demonstrated in two real-world production systems.

They driver for a change can be e.g. related to quality, safety, changes in external circumstances or regulation. These engineering changes often referred as Engineering Change Requests (ECRs) are largely generated through product development projects and are often stored in database while worked and later for some form of knowledge management purpose. </div> <div>Despite ECR being captured and stored it is often cumbersome for product developers to identify historical ECRs due to the vast amount of them. Historical ECRs might contain valuable knowledge relevant to a current design and it is often wondered if the ECR content might be analyzed in a new way insightful way. The content of ECR data must contain information permitting identification of the types of errors and changes made, including part title, part name, part number, problem description, root cause, solution and test results. </div> <div>This thesis primarily focuses on ECR data in combination with three components necessary to perform data mining and data analytics: exploring and collecting ECR data, collecting domain knowledge about ECR information needs, and applying mathematical tools for solution design and testing. </div> <div>Results show a list of engineering information needs related to ECRs, examples of visualizations based on unstructured data, industrial case study where complex product development processes are modeled using the Markov chain Design Structure Matrix, and studies that investigate how advanced searches based on natural language processing techniques and clustering within engineering databases.</div> <div><br /></div> <a href="" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" /></a><a href="" target="_blank">Read more</a><br /><a href="" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />​Ívar Örn Arnarsson on Linkedin​</a></div></div></div></div> <div><a href="" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Zoom link​</a></div>Fri, 08 May 2020 00:00:00 +0200 enables a more robust electrical system<p><b>​​The use of more renewable energy sources in Europe will rely on the smart electric grids, able to distribute and store energy matching production and demand. Circuit breakers are safety-critical components of electric grids, associated with very high and recurring maintenance costs. By adding graphene to the circuit breakers, the electrical system will become more robust and reduce the costs of maintenance drastically.</b></p><div>Low voltage circuit breakers, common in domestic and industrial applications, need grease to function properly. The grease is applied to all circuit breakers during manufacturing. The problem is that the grease stiffens and dries out with age and has a narrow temperature range. This leads to a metal-to-metal wear that must be serviced at high maintenance costs, and to an increased risk of circuit breaker failure. Lack of lubrication is the number one problem that test technicians find when servicing circuit breakers in the field. </div> <div> </div> <div><br /></div> <div> </div> <div><h2 class="chalmersElement-H2">Self-lubrication properties enables maintenance free operation</h2></div> <div> </div> <div>Graphene is a material with self-lubricating properties; the Swedish company ABB, partner of the Graphene Flagship research program, has recently demonstrated that multifunctional graphene-metal composite coatings could improve the tribological (interactive surfaces in relative motion) performance of metal contacts. ABB will thus lead a new project, starting in April 2020, with the aim to take such graphene-based composites to commercial applications.</div> <div> </div> <div>The project, named “Circuitbreakers” is one of eleven selected Spearhead projects funded by the Graphene Flagship, Europe’s biggest initiative on graphene research, involving more than 140 universities and industries located in 21 countries.

The aim of the Circuitbreakers project is to develop a fully functional and tested prototype ready for industrial implementation in just three years. This new generation of circuit breakers will be self-lubricant and have a wider temperature range than existing circuit breaker options. This will enable maintenance-free operation, which will save business huge costs and reduce the risk on any undesired outage of the electrical system due to circuit breaker failure.</div> <div> </div> <div><br /></div> <div> </div> <div><h2 class="chalmersElement-H2">Extensive experience of graphene- and graphene-based composites</h2></div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/IMS/Material%20och%20tillverkning/VincenzoPalermo.png" alt="Vincezo Palermo" class="chalmersPosition-FloatLeft" style="margin:5px 15px;width:141px;height:155px" />Prof. Vincenzo Palermo and Dr. Jinhua Sun from the Department of Industrial and Materials Science, Chalmers University of Technology will support ABB in the spearhead project providing new solutions to process graphene in coatings, to fabricate graphene-enhanced circuit breaker prototypes for practical application in the industrial scale.

The initiative started in Canada to promote awareness on strain injuries of various types and celebrates 20 years 2020. Professor Anna-Lisa Osvalder at Chalmers University of Technology is an expert in ergonomics and gives her best tips on how to avoid RSI.</b></p><img src="/SiteCollectionImages/Institutioner/IMS/Design%20and%20Human%20Factors/200x249_AL-foto-CTH.png" class="chalmersPosition-FloatRight" alt="" style="margin-right:15px;margin-left:15px" /><span style="background-color:initial"><strong>Why do you get RSI?</strong></span><div>It could happen if you for some time have exerted certain muscles through low-strain tasks. Like using a computer and a computer mouse in your everyday work. You might experience a pain in the arm, neck, wrist and fingers. That pain is caused by an increased strain in the muscles and ligaments, tendons or nerves being overloaded. Also, stress can increase the risk of RSI because you often tighten your muscles.</div> <div>When working with a computer mouse, you hold your hand in an unnatural position, both holding the mouse and clicking it. The hand is bent back in an unnaturally large angle between the forearm and the hand and the muscles are constantly strained. In addition, the hand is usually slightly twisted, with a turn to the little finger. This causes a greater pressure on certain nerves and the muscles in the forearm are forced to work in an unnatural way.</div> <div><br /></div> <div><strong>What did you find in your study of so-called ergonomic computer mice?</strong></div> <div>First, I would like to point out that a so-called ergonomic computer mouse cannot have good ergonomics in itself. It is only in collaboration with the user we can study how well it can avoid incorrect use which may cause RSI.</div> <div>In our evaluation, we took a closer look at four ergonomic computer mice of different brands. We examined two aspects – usability problems and use errors – in interaction with the mice.</div> <div>In the study of the four mice, we found 75 possible ways to use the mice incorrectly! The user did not understand from the design of the mouse how it was supposed to be held or which finger to use to click. From this, we found that it was difficult for the user to guess how an ergonomic mouse should be used properly. And the wrong use causes a strain in the wrist, hand and fingers which in the long run can lead to RSI.</div> <div>The study shows the importance of informing and educating the users on how to handle an ergonomic mouse properly. We also found that it is important to develop mice that you intuitively understand how to use. The best design is the one where you can only use the product in one way – the correct way.</div> <div><br /></div> <div><strong>What are your best tips to avoid RSI?</strong></div> <div>There is no special treatment for RSI. Instead you need to find a way to prevent long-term strain. These simple tips can prevent RSI and reduce existing problems:</div> <div><ul><li>Take more breaks! Rather many short breaks than a few long ones.</li> <li>Change work posture frequently.</li> <li>Stretch your body and your wrists (see picture).</li> <li><span style="background-color:initial">Avoid using the computer mouse – learn how to use keyboard shortcuts instead.</span></li> <li>Change hands maneuvering the mouse. It is difficult at first, but practice and you will get in to it.</li> <li>Make sure the mouse and keyboard are at a proper distance from the body, the closer the better.</li> <li>Keep the wrist straight, slightly twisted towards the little finger when using the mouse, ie try to hold the wrist in a natural posture to reduce strain <em>(see picture above).</em></li> <li>Reduce work-related stress.</li></ul></div> <div><br /></div> <a href="/en/Staff/Pages/anna-lisa-osvalder.aspx"><div><strong>Anna-Lisa Osvalder </strong><span style="background-color:initial;color:rgb(51, 51, 51);font-weight:300">researches in ergonomics and biomechanics since 1986.

Congratulations to Maria Siiskonen, who was awarded a grant of SEK 50,000 from the Chalmers Foundation and Göran Wallberg&#39;s Memorial Fund in 2019, which will give funding for a four-month stay in Copenhagen, Denmark.</b></p><br /><div>
The Chalmers alum Göran Wallberg (VV-45) generously donated 2 million with the aim of helping students and younger researchers to gain international experience during their studies. The grant covers the areas of ICT (Information and Communication Technology), Production Technology and Environmental Technology.
</div> <div>&quot;It's a very nice Christmas present,&quot; says Maria Siiskonen, PhD student at the Department of Industrial and Materials Science, Chalmers. “I will use the grant for a research stay at the Technical University of Denmark, DTU, to learn more about adaptable manufacturing systems for personalized medicines.”</div> <div><br /></div> <div><strong>
Looking for solutions
</strong></div> <div>Maria Siiskonen's previous research has focused on product design and how different functionalities can be incorporated into medicines, for example in tablets. It makes it possible to adapt the medicine to the needs of the individual patient and thus optimize patients' treatments against a number of different diseases. 
</div> <div>A consequence from product customization is the accelerating number of product variants and previous studies indicate that current pharmaceutical production systems are not flexible enough to enable production of customized product in an economically feasible manner.
 </div> <div>“I want to take a closer look at how the production systems for individualized medicines to find how they should be designed, both from an economic and sustainable perspective. My focus will be on the adaptability and flexibility of the systems to meet the demand for patient-adapted product variants.”

 </div> <div><br /></div> <div><strong>Strong research at DTU attracts
</strong></div> <div>Maria explains that DTU's research group has a good reputation in the research area, in terms of the field of product customization and strategic approaches to product portfolio design.</div> <div>“Being here for a couple of months, will give me excellent opportunities to get a first-hand insight into their methods, discover new tools and hopefully get optimized product development methods to bring home with me. I think this will be an excellent opportunity to develop as a researcher”, concludes Maria.

A Novel Framework and Evaluation Methodology.&quot; on February 6, 2020. Opponent: Prof. Thomas J. Howard, Centre for Technology Entrepreneurship, Technical University of Denmark, Denmark Examiner: Prof. Rikard Söderberg IMS ​​</b></p><strong>Popular description</strong><div><div><div>Average consumer sees a car’s quality as a fancy mixture of a reliability, performance, design, aesthetics, and own previous experiences, unlike as a combination of mechanical parts, software pieces, advanced materials, cutting-edge manufacturing processes, with technical knowledge, skills and high production volumes – all ingredients involved into the modern car creation. Quite often, “humans do not see and act on the physical qualities of things, but on what they mean to them.” Closing the door of a Mercedes-Benz S-Class limousine produces signature sound with a vault-like thunk, making us react by generating multisensory images within ourselves. Handling certain premium quality wood panels gives a more sophisticated tactile impression than with a cheap plastic. The first olfaction, when entering a new Cadillac vehicle, creates a feeling of luxury, very different from that in a used car sold by a nearby car dealer shop.</div> <div><br /></div> <div>As one can see, understanding human’s perception of quality is a big challenge for researchers and practitioners. “What product features require the most attention for successful car design?” – The question engineers and designers need to answer under the pressure of shrinking product development time, a boost of available technologies, and financial limitations. Not to mention, the answer is expected to be given in numbers to sustain a fierce competition in the automotive industry. In that case, if a car manufacturing company wants to secure the ability to meet the consumer’s expectations, there is a need to control the perceived quality. Easy to say, hard to do.</div> <div><br /></div> <div>Perceived quality is a complex, multifaceted adaptive system - a system where a human is the main agent. Therefore, many perceived quality attributes are difficult to define explicitly. This fact creates a “wicked problem” for any car manufacturer. </div> <div><br /></div> <div>To confront the problem, we need to name it. For this reason, the perceived quality in engineering science has been defined and structured as the Perceived Quality Framework (PQF), in the form of a two-dimensional typology: (i) Technical Perceived Quality (TPQ), encompassing intrinsic attributes - everything that is part of a product and can be controlled by design and/or engineering specifications; (ii) Value-based Perceived Quality (VPQ), including extrinsic attributes - such as brand image, brand heritage, affective consumer judgments, design, hedonic or social values, the impact from other global attributes, advertising, and marketing promotion techniques. </div> <div><br /></div> <div>The perceived quality domain is a place where the product meaning, form, sensorial properties, and their execution intersect with human experience. Such an experience is driven by the interplay between product quality and its context. The ultimate goal is to find the trade-off between perceived quality elements. This resulted in the creation of the Perceived Quality Attributes Importance Ranking (PQAIR) method. The novel methodology was created to assist the engineer or designer in the decision-making process regarding the relative importance of perceived quality attributes for the final product. The PQAIR method illuminates the interplay between technical characteristics of the product and customer perceptions. The successful implementation of the method can help find an answer to the question, “What makes you, as a consumer, to fall in love with a specific car?” This is, after all, a very “expensive” question. Billion-dollar decisions in the automotive industry often rely on predictions and assumptions about how a customer will perceive and evaluate such a complex product as a car. The ontology of PQF and its principles shifts the perceived quality evaluation processes towards the objective and reproducible side. </div></div> <div><br /></div> <div></div> <div>Keywords: perceived quality, automotive, product development, product quality, premium, luxury,</div> <div>knowledge management, design, aesthetics, engineering;</div></div> <div><br /></div> <div><a href=""><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the thesis</a></div> <div><a href=""><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Kostas Stylidis on LinkedIn</a></div> <div><br /></div> <div><div><strong>Public defence</strong></div> <div>2020-02-06 09:00</div> <div>Virtual Development Laboratory (VDL), Chalmers Tvärgata 4C, Johanneberg Campus, Gothenburg</div></div> <div><br /></div> ​Wed, 15 Jan 2020 00:00:00 +0100 Sustainability Day: Minimised waste and maximum use<p><b>The 8th of November, it&#39;s time for this year&#39;s edition of Chalmers Sustainability Day.

Tell us a bit about the arrangement!</strong></span><div>&quot;We will start the day with a master class session, where some of Chalmers' own researchers, leading in their respective fields, give lectures about their research linked to the theme of circular economics. We want to give a broad perspective on the concept, ranging from business models, materials, product development to future civil society. The first talk of the day will be held by an invited speaker who can give a broad understanding and background to the theme.&quot;</div> <div><br /></div> <div><strong>Circular economy - how would you describe it?</strong></div> <div>&quot;Oh, there are many descriptions of it. To me it is about being able to dare to change from linear to circular business models. To achieve true sustainability, we not only need to change our technical conditions, but also the ways we consume. Everything has to be linked, from business value for those who produce and deliver products and services, to the actual customer benefit.&quot;</div> <div><br /></div> <div><strong>What do you hope Chalmers Sustainability Day will bring?</strong></div> <div>&quot;I want more people to be inspired and take circular economics into account in their research, in a wider sense than today. Chalmers vision to make the future more sustainable is reinforced by paying attention to all research internally. I hope this will create awareness of ongoing activities, so that synergies are found in various research areas.&quot;</div> <div><br /></div> <div><strong>Is it still time to propose something for the programme?</strong></div> <div>&quot;We have closed the agenda for the master class session but there are still a few slots open in the afternoon progamme. If you have a suggestion – talk to us! We hope for a greater participation of researchers and teachers this year. A possibility that not so many have reacted to is the poster exhibition. We would like to see more proposals here!&quot;</div> <div><br /></div> <div><strong>The collaboration with the Student Sustainability Week Act! Sustainable is new this year! How will they contribute? </strong></div> <div>&quot;Above all, they can contribute with their perspective. The students have high demands on Chalmers as a university to work more with sustainability internally, but they also push to steer their education towards the circular perspective. We hope many students will show up and be able to take part in research and be inspired to make their own circular choices in the future.&quot;</div> <div><br /></div> <div><br /></div> <div><br /></div> <div><div><b><img src="/SiteCollectionImages/Areas%20of%20Advance/Production/750x340_Lars-Nyborg_SDG12.jpg" alt="Picture of Lars Nyborg, director of Production Area of Advance" style="margin:5px;width:680px;height:312px" /></b><br /><br /><span></span><em>This year's theme is broad and embraces much of the research within the Areas of Advance, says Lars Nyborg, Director for Production Area of Advance and the organizer 2019 for Sustainability Day. Photo: Carina Schultz​</em><br /><br /><b>Hello Lars Nyborg, Director for the Production Area of Advance and responsible for this year's sustainability day at Chalmers. Why the choice of circular economy as a theme?</b></div> <div></div> <div>- We chose to focus on circular economics, as it is a theme that unites many of Chalmers Areas of Advance. The solutions of the future lie in how we implement circularity in society and here we have an opportunity to discuss it thoroughly. The theme can work both for big issues and in the small perspective as an individual citizen. We believe the theme can inspire and provide new knowledge for everyone - students, researchers and other staff at Chalmers.</div> <div><br /></div> <div><strong> What does circular economy mean to you?</strong></div> <div>- It's a quite difficult concept and theme. There is not only one answer, but many. I would like to compare the concept of circular economy to an umbrella, under which several different contexts and definitions can be gathered.</div> <div><br /></div> <div><strong>What do you hope visitors will bring home from the event? </strong></div> <div>- I hope for increased commitment and an understanding of what circular economics is. I also wish for a broadened understanding that a sustainable future is a matter of creating solutions. I would also be interesting if the discussions include a questioning attitude regarding suggested solutions. A sharper dialogue and debate are important for showing a sustainable way forward.
