Vacuum - temporary objects Johannes Voelchert The technique of creating a vacuum allows the construction of temporary objects in a sustainable way. The different filling materials are non-permanently bonded together since the stability is created solely by the evacuation of air. Thereby the use of new material is minimised. As filling materials, even ever-present ordinary objects can be used, which reduces the amount of new materials needed. Due to the non-permanent connection, the components are fully separable. The foil is recyclable and the filling material is even reusable. Different use-cases are demonstrated: a fully functional hammer using some spaghetti, some lentils and a fifty-cent coin in a vacuum foil - nothing one does not have at home anyway

construction without permanent connections

Conical filling material enables curved surfaces with high static load capacity similar to the round arch principle. The construction assembles itself during vacuuming.

A suitcase stands around a lot of its time and takes up a lot of space. My alternative uses a light and stable semi-finished product made of nylon fabric and loose plastic rings. When the suitcase is not in use, the structure can be filled with air and the suitcase can be rolled up to save space. Before the next use the vacuum is generated again with the help of a hand pump, giving the suitcase its stable form.

monoscale – a monomaterial approach Marcel Bohr We want to own and consume without limits. But what approach prevents products such as electronic devices from having a large ecological footprint? One possibility is to replace electronics with a monomaterial that replaces electronic functions by material-immanent properties. This is how the idea of a kitchen scale was developed. The shape of monoscale allows the residual stress of the material to be used as a measure: The more the scale is loaded, the more it deforms, which is indicated on the scale in grams. The material used is PETG, a polyethylene terephthalate (PET) modified with glycol, which is characterised by high viscosity and impact strength. It can be bent at any angle without breaking. Also, it complies with food safety standards to be used in the kitchen. The monoscale can be produced by injection moulding. This allows it to be manufactured in a single piece in a very cost-efficient way.

ToToGo - toast that needs no toaster Julia Ernst Do we need to rethink sustainability? Some facts: Thin and small foil packaging is not being recycled. Neither is the packaging of toast. After use, it is transported by a truck to a waste incineration plant, where it is burned in order to at least regain the energy from that foil. At the same time, we plug in a toaster at home to toast the toast. The toaster is made of an enormous amount of precious materials, which are processed in a such way that hinders recycling and it uses electrical energy when toasting. So, what if we use the energy of the packaging directly and burn it on the table and thereby toast the toast? Why not save all the hassle, materials and transportation? This proposition is truly possible – by using PE, a common packaging plastic, that burns without toxic by-products. From an environmental point of view this concept makes sense: According to the MIPS concept the estimated environmental impact potential of a toaster toasting 100 toasts is about 60 times bigger than for 100 ToToGo toasts. (considering the material inputs for the production of the toaster, the used energy to toast the 100 toasts, the packaging and the transportation of the toaster and the packaging of 100 toasts – not including the toasts themselves.) What does this venture mean for us as consumers, for the toaster industry and for our general perception of sustainability?

The same principle is transferred to a sports shirt: While doing sports sweat can be used to "print" a logo on one’s shirt. This effect not only motivates to sweat more, it is also more sustainable. A combination of two different cellulose fibres allows for this effect. The resulting monomaterial shirt can be easily recycled in comparison to those with prints.

Pose – a wedding dress grown from mycelium Sophie Turner Weddings have a big impact on our natural environment. From the many guests, who travel to the location, over large quantities of food, to loud music, the rings and the wedding dress. Considering the fact that often the dress is used for just one day and then spends a life time in a closet, I propose a concept for a disposable wedding dress. The dress is made of mycelium – the “roots“ of fungi – a highly sustainable, fast-growing material. It does not require many resources and can be harvested almost everywhere without infringing on the space we need for growing food. Aside from the obvious economic benefits, the dress is perfect for the latest trend, the post-wedding photoshoot, at which you are likely going to destroy the dress, but have great wedding pictures in return. The mycelium dress comes with special effects, for example, it could glow in the dark, it could lose some patches when in water, creating a new pattern, or include the bloom of flowers as the dress comes into contact with water. After a photoshoot in a lake or in the sea the dress can't be used again, but that's alright. The wedding is over and there are breath-taking pictures as a memory. These added extras in combination with the fact that the dress is grown only for oneself give the garment a tremendous personal attachment.

MudBud – a clean way to play with dirt Netta Nahardiya There are many qualities to mud for children other than being advantageous to the immune system. It encourages creation and imagination, develops the brain, and more. Many kids these days don't get to play with mud. The main reason is that mud is outside and the outside might be full of unpleasant dirt. As parents, we want to keep our kids safe, or "clean", we would rather buy the "clean" brand new plastic car toy than let our kids play with dirt. MudBud is dirt that suits parents.

Self-Check – to monitor nutrition Ferdinand Hintz Malnutrition is a worldwide problem due to industrially processed food and due to a lack of knowledge. In order to enable people, especially children, to check the quality of their food, I developed a simple and playful self-test to check one’s own vitamin C levels. Tests for other vital vitamins and minerals are to follow. The concept is based on the fact that the body excretes surplus vitamins in urine. If the body is saturated the rest ends up in the toilet. A toilet gel serves as a colour indicator to show possible saturation. The gel dissolves with each refill, just like ordinary toilet gels. Yet, its colour changes from blue to transparent in the presence of vitamin C in the urine. Through the immediate, everyday self-test an awareness of balanced nutrition can be generated.

downhill – a sledge made of ice and snow Martha Sophie Kikowatz From the idea of shortening the lifespan of a sledge to its actual service time, two solutions emerged. The use of ice and snow limits the existence of the products to the time and place of use. The sledge made of ice: Fill the reusable moulds with water. Add fir needles to the water for reinforcement (e.g. from a Christmas tree). Put the moulds in the freezer. When it is cold enough outside, assemble the individual parts and connect them with water. After sledging, the sledge can be left behind at the end of the slope.

The sleigh bag: The sleigh bag is perfect for a hike in the snow. It can be carried up the mountain almost unnoticed in a pocket. At the top, it is unfolded and filled with snow. At the end of the track, the bag is emptied and fits back into the pocket.

1k  – a one thousand mile shoe by Louis Möckel The average walking distance a human walks within one year is about one thousand miles. This shoe is designed to not last any longer than this. Considering, that we attend to buy a new pair of shoes each season and so create huge amounts of non-recyclable waste, this model offers a sustainable alternative to modern sneaker footwear. It consists of only two materials and can be disassembled into its raw materials by just one step. Through the reduction of materials, the manufacturing process is broken down to one injection moulding process and no glue is used. The shape of the shoe adapts to the customer’s feet by tightening the shoelaces individually. By distributing it through a modern selling-concept, it allows the user to buy only one pair each by handing in his worn out one to create a circular material flow. The modular design serves the opportunity to individualize the model to each customers needs and taste.

Paper Shoe by Luis Kucharski Sneakers are disposable products that usually do not survive more than one season. Nevertheless, they are not designed to be recycled easily. Paper shoes should be a sustainable alternative without directly appealing to the consumer's behaviour. After use, they can be thrown into the paper bin.

stable - instable a table for short-time use made of recycled plastics. It is made to be recycled after an average use of three years, which is the normal lifespan of students' furniture.

Wegwerfen, recyceln oder dieses System in Frage stellen?
Einige Produkte leben ewig, werden sogar von Generation zu Generation weiterverebt. Andere Produkte haben eine kurze Lebensdauer, werden kein zweites Mal benutzt, sondern landen im Müll. Nur selten entsteht erneut aus ihnen ein gleichwertiges Produkt. Doch ist das lange Leben immer besser? Oder gibt es Anwendungen und Situationen, in denen Wegwerfprodukte sinnvoller, nachhaltiger und sogar besser als dauerhafte Produkte sind? Entstanden sind eben solche bewusst kurzlebigen Nutzungskonzepte, die dennoch bzw. gerade deshalb nachhaltig sind.
Umdenken, verschwenderisch Produzieren, Konsum als Nachhaltigkeitsstragie – Provokation oder Antwort
Mit externen Partnern wurden anhand tatsächlicher Life Cycle Analysen Konzepte, Materialien, Services und Anwendungsszenarien gegenübergestellt und hinsichtlich ihrer Nachhaltigkeit bewertet, neukonzeptioniert und sinnvolle Szenarien entwickelt, die überraschen – nicht nur weil sie zum Wegwerfen gestaltet sind.

Throwing away, recycling, or questioning this system? Some products live forever, are even passed on from generation to generation. Others have a short life, are not used a second time and end up as garbage instead. Only rarely an equivalent product emerges from them. But is a long life always the better one? Are there applications and situations where disposable products are more sensible, more sustainable and even better than durable products? We made it our task to develop deliberately short-life usage concepts, which are still, or precisely for this reason, sustainable. With external partners, we compared concepts, materials, services and application scenarios and assessed them with regard to their sustainability. We developed new conceptions and sensible scenarios that are surprising – not just because they are designed to be discarded.
