The FooDi

Dialogues for more sustainable diets


Changing one’s (eating) habits is hard and information concerning healthy, eco-friendly diets can be overwhelming and contradicting. Therefore, we want to support people who want to make the change by creating a place for open exchange about environmentally friendly food. The FooDi provides a cooking hub to meet, cook and learn from each other.


FooDi, the cooking hub, offers a shared kitchen space, where community members can learn by cooking and eating with other food lovers to have a more sustainable and healthy diet. We offer guided and personalized activity on site!

Our goal is to engage and empower individuals to make informed diet choices. Our three pillars are: learn-by-doing, fun and knowledge exchange.

Our team is now composed of of three environmental engineers: Annie, Giovan Battista and Giulia. We are food and nature lovers. With this project, we are trying to combine our two passions!

Introducing a novel, sustainable protein crop.


LemnaPro develops a technology that enables the sustainable and economic cultivation of Wolffia for human nutrition.


Wolffia is a water plant with high levels of protein and a very rapid growth. It has traditionally been harvested and consumed in Asia. It is our aim to introduce it to Europe as a healthy and delicious food ingredient.

The introduction of this novel crop into our food system will alleviate the pressure on natural resources related to protein production today.

To achieve our aim in light of the above we are developing a tailored hydroponic system for Wolffia, which currently already yields 20 times more protein per area than soy.

Beer brewing for people who care.


For our climate, for our biodiversity, and for some of the few remaining forest dwelling indigenous tribes on this planet, it is crucial that we support the momentum of existing bottom up initiatives to stop further deforestation in the Amazon. The ‘Paraperu’ project contributes to poverty alleviation of Peruvian Brazil-Nut producers and with it the improvement of forest-management practices.


In order to collect financial resources for bio-certification and rejuvenation planting actions, the Brazil-Nut concessions in Madre de Dios, Peru, will ennoble and sell small amounts of high-quality Brazil-Nuts in Switzerland. The current idea is to use them to brew a delicious nut-ale beer. Paraperu will be organized as a Swiss association.

Instant Windows Project

Restoring Shelter in Conflict Zones


Join our team! We are looking for manufacturing engineers, automatization specialists and, generally, hands-on makers with a social mind!

The Instant Windows Project aims at providing an inexpensive and reliable method to restore broken windows in conflict zones and areas affected by natural disasters. With Instant Windows, we offer a solution to quickly and easily repair broken windows by using a patent pending, translucent double-layer plastic sheet. It provides both daylight as well as insulation.


A broken window may seem like a small problem – but depending on the climate, it can render homes uninhabitable, making their residents more vulnerable, endangering their health, and threatening them with displacement or homelessness. Every year, millions of people around the world are driven into this cycle of vulnerability for different reasons. One major reason is conflict.

The Instant Windows project aims to intervene early on by offering a simple, inexpensive replacement for broken windows, restoring people’s shelter and preventing a slide into displacement and further vulnerability.

Conflict simultaneously increases the risk of broken windows and makes them more difficult to repair: markets in affected areas are understocked, services are disrupted, and people’s financial resources are depleted. Shockwaves from shelling and explosions affect windows in a far larger radius than the explosion parameter. As conflict moves to more urban contexts, thousands of people lose vital protection against the elements.

Instant Windows doesn’t aim to offer a flashy gadget, but rather an inexpensive tool that is both accessible and practical, even under extreme circumstances.

Akademische Raumfahrt Initiative Schweiz


ARIS brings together students from Swiss universities fascinated by space exploration. Formed around ETH Zurich, HSLU, and ZHAW, we engage our members in engineering challenges by integrating theory and practice. We do not only build rockets, we embrace the personal development of our members. Together with our partners from industry and academia we aggregate the required knowledge. And on the way there, we educate future engineers and leaders in hands-on project work. Our ultimate goal: to fly a student demonstrator in Low Earth Orbit by 2029!

Together, we believe, we can reach the stars.


Project TELL
At its very first participation at the Spaceport America Cup, ARIS won the Charels Hoult Award for Modeling and Simulations for its technical achievement – one of the ten main awards of the competition. Despite a motor failure and the resulting explosion of the rocket a few seconds into the flight, the project TELL was very well received for its technical and operational excellence.

Project HEIDI
With project HEIDI, ARIS – in the second year of its existence – competed for the second time at the Spaceport America Cup in New Mexico and made the second place in its category of 10’000ft and commercial-off-the-shelf solid motors with a nominal flight. Project HEIDI was a full success.

Project RHEA
As a team of 10 students, project RHEA developed the first ever student-built rocket engine test stand in only one year, which lays the auspicious foundation for future engine development projects. Additionally, the first generation of a hybrid rocket engine was designed, manufactured and tested.

Project EULER
Now, in the third year, project EULER is aiming for the first flight to a height of 30’000ft at the SPAC 2020 in New Mexico. The new team consisting of more than 30 students from 6 different Swiss universities will develop the first ARIS generation of supersonic sounding rockets.

Project IRIDE
Starting from autumn semester 2019 the focus project IRIDE is developing the next generation of a hybrid rocket engine. With an aiming thrust of 5 kN this engine shall be implemented into the rocket for the 2021 SPAC.

Thesis with ARIS
From now on, there is also the possibility to write a Bachelor-, Semester- or Master thesis in cooperation with ARIS. You can either chose a topic from our project pool or bring in your own ideas. We support you with the knowledge of our active members and alumni, with providing workspace and with our contact to partners from industry.


SmartBreed GmbH

SmartBreed aims to automize breeding of Grasshoppers


With our SmartBreed start-up, we aim to produce automated breeding stations for grasshoppers. The stations will be equipped with various sensors to gather and analyse data, in order to optimise the production process. This will allow more efficient and cheaper breeding, which will reduce the price of grasshoppers and enables them to compete with other protein sources such as meat and plant derived proteins. SmartBreed is a green initiative for a more sustainable future.


Digit Soil

Changing how we see soil


Microbes are vital for soil health, but they are vastly understudied, because current methods are complicated and labor-intensive.
With Digit Soil, we propose a portable device to measure microbial activity directly in the field. With our solution, anyone can reliably gather data to contribute to the basic science that will help to protect our soils for future generations.


Over-grazing, -tilling and -fertilizing are destroying soil at 10 times the rate we are replenishing it. We are treating our soil like dirt. But what makes soil? It is microbes!
Do you know that one tablespoon of soil is filled with more microbes (bacteria and fungi) than there are humans on the whole planet? Microbes eat organic bits in the soil and produce nutrients for plants.

We know, in facts, that microbes are crucial for soil health, but we just don’t know well enough the microbial health of our soils. This is our bottleneck. Today, in order to measure the microbial health, the sample of the soil has to be brought from the field to the labs in buckets covered with ice. That in itself is making the results not reliable, since the soil is affected during the oftentimes long travels. We need new and better tools than we can use directly in the field.

Our soil sensor allows measurement on site. With a simple to use device, which you just stick into the soil right where the soil is. By doing this we limit bias and make soil microbial health measurements a more reliable and available source of information. Our journey starts here. As a next step, we wish to further develop our prototype and bring on board researchers. They will help us gather enough data so that we will be able to use our device for future soil maintenance and protection. This as a result will keep bringing food to our tables and keep earth climate in tip-top shape. For more information visit

Student Document Repository

Abstract is a shortcut to all exercises, solutions, lecture slides and information for your studies. We aim to put an end to the multitude of websites every student has to navigate in order to get started on their work.


Adjusting to life at ETH can be confusing at times. The sheer amount of websites students need to go through to access working materials and information is overwhelming.

Our goal is to make all relevant learning documents easily available to as many students as possible. This allows them to focus on their studies, making the time spent studying more efficient.

In order to provide this service, the Napoly-team consists of and relies on volunteers from all over ETH, who upload and update content daily.

If you are interested to know how this works or would like to participate in some way, feel free to contact us via email.

Sufficient protein for preterm infants


Premature births cause low birth weight, brain defects, and various diseases. It is thus crucial to minimize counter effects by an optimal preterm nutrition with fast weight gain.

Exclusive human milk based nutrition significantly reduces the chance of necrotizing enterocolitis (NEC), the leading mortality cause among preterm infants. However, human milk by itself has a lower protein content than needed for preterm infants (four-times too low) and need to be fortified. We provide a new and innovative solution for this problem.



Currently available commercial solutions focus on bovine-origin protein fortifiers that are added to the human milk. However, this can lead to additional health risks due to its non-human origin. We solve this problem by providing protein fortifiers obtained from human milk. We plan do so by a simple and preferably automated device designed for hospitals, which can provide the human-origin protein fortifiers on-side in real-time and is operated by nurses without special education. Currently no automated protein enrichment process for human milk exists and expensive lab equipment is needed including trained personnel.
