To Mattias and Sophia

Dear Mattias and Sophia,

It has been already seven months since we posted our announcement for recruiting two long-term volunteers for the Äerdschëff project. While posting the article a lot of different emotions rushed through our bodies. They were feelings of sadness and happiness, of fulfillment and excitement.

The announcement was telling us that time was flying. Soon we had to tell goodbye to Mattias and Sophia.

A lot has been done during this time, but we want to dedicate this article to our beloved European volunteers for the time August 2018-2019 and to our newcomers Saul and Ledina.

We remember how happy they were when they joined us and we felt so lucky to welcome them in the team.

From the beginning, they expressed their strong desire to learn new things related to the project; reflecting patience in the learning process in every stage of this journey among/with us. Having them on the team made a huge difference. Mattias and Sophia were so great to work with. They were so flexible and always being willing to lend a hand. Their positive energy, the innovative ideas they initiated and their understanding of the world, are some of the key elements in our relationship. On top of that, they were really good at cheering up everybody and bringing moments of laughter and joy.  They always found a way to get things done, and done them well. Even when the going gets tough, they continued to have the best attitude and came up with fantastic ideas. We really enjoyed working with them.

“Working with you has been such a pleasure from day 1 till the very last moment. Through this article we want to thank you for the amazing work you have done.

Keep up the great work!

You’re awesome!”

And then history repeated itself; this time, instead of having Mattias and Sophia on the Ä-team, we welcomed Saul and Ledina who arrived during our first ‘chantier participatif’ this summer, August 2019.

 “Welcome in the team and enjoy this journey.”

Recruiting for a long-term payed volunteering opportunity in Eco-construction

Recruiting for a long-term payed volunteering opportunity in Eco-construction

Would you like to embark on the journey of a lifetime for a year-long paid European Solidarity Corps experience (formerly European Volunteer Service, EVS) on an Earthship-inspired project in Luxembourg? Are you curious about eco-construction, volunteer engagement, the Transition movement and working in an intercultural environment? Are you between 18 and 30 and a resident of the EU?

We have an opportunity for you to step into the Äerdschëff team, starting beginning of August 2019 for 12 months. If you are interested in being part of a great project under the conditions of the ESC European Solidarity Corps programme, write to us at with your CV and motivation letter until 31st May 2019. Looking forward to your application!


CELL is currently working on the design and implementation of an ecological and participatory building project that is supported by public authorities and a philanthropic foundation. We are planning to build the earthship during 2019-2020, so this is an exciting phase to join for. Through this project, CELL combines responses to current societal challenges in terms of energy transition and training in eco-construction. The project that we’re developing is a self-sufficient building, based on the principles of the ‘Earthship’, i.e. autonomy in terms of water supply, electricity supply, wastewater treatment and thermoregulation. The project also has a strong food component. The materials are as far as possible natural or reclaimed/recycled. For more information about the project, see our webpage or visit the Äerdschëff facebook page.

The local community where the project will be realised: The immediate environment is the Canton Redange, a cozy and progressive region on the border to Belgium, 45 minutes away from Luxembourg-City. There are many potential points of cooperation also with the surrounding municipalities.

CELL is organised in a network-like way, so that we have action-groups in different parts of Luxembourg, some in rural, some in urban places. The volunteer can participate in various local transition initiatives and support them.

Luxembourg is an intercultural, wealthy country with an enormous ecological footprint, so it is an interesting place for a non-profit such as CELL to operate in promoting sustainability. It is also a very small country where you will find that contacts and people allow you to open doors and push forward great projects.

We are looking for a person interested in eco-construction, ecology and self-sufficiency. It is very important that the person is self-motivated and capable of working independently, but he/she will be accompanied by a team of technical and general support.

What we can offer to ESC-volunteers in terms of service and learning opportunities during 2019:

– taking an active part in the project “Äerdschëff” in the Redange/Atert region

– acquiring permaculture skills and aspiring to food autonomy on two different sites

– involvement in an intercultural team of part-time volunteers who are running CELL

– self-management and communication skills

– group process skills

– participation in trainings and events organised by CELL

– realising your own heart project in the context of the Äerdschëff

– living in a vibrant social environment with lots of ecological initiatives and a great cultural wealth

The role of ESC volunteers:

ESC volunteers will participate in daily CELL and transition activities, as necessary. They will actively participate in the running of two permaculture sites and they will be asked to pursue their own heart projects developed jointly with CELL.

Possible activities in which the volunteers will be involved and activities the volunteers could create in our organisation:

– Eco-Construction: Participating in the realisation of the Earthship, involving various tasks from organising and gathering materials, coordinating volunteers and logistics, being in contact with collaborating organisations, to hands-on work on the construction site, …

– Gardening: planting, weeding, cleaning, mowing, mulching, seeding, composting, pruning, harvesting, tending, etc. in a vibrant community environment…

– Household management: cooking and kitchen duties, looking after the participants of courses, tending the CELL rooms

– Organisation: assisting in organising and running CELL events, courses and activities, running meetings and steering group processes

– Participation and representation: representing CELL at network meetings, festivals, demonstrations, conferences, fairs, gatherings and other public events

– Administration: updating blog, website, email lists, social media, membership correspondence, documentation, …

The profiles of volunteers we would like to host:

– Experience in Permaculture, Transition and / or self-sufficiency.

– Being at least familiar with self-build situations (chantiers participatifs).

– Being at least familiar with eco-social organisations and ways of proceeding.

– Being passionate about agroecology and low-impact living.

– A good level of French is a bonus in Luxembourg, especially when dealing with local authorities such as in the ‘earthship’ construction project.

– Own way of transport (ex. car), or a driver’s licence is a bonus when working in the countryside in Luxembourg since public transport is limited.

To apply, you must fulfill the ESC criteria, i.e. be between 18 and 30 years old and be a resident of a EU country or one of the ESC Partner Countries (you can find a list here). Please note that we are only recruiting a volunteer for a full year.

Recruitment process:

We will recruit the volunteers on the basis of their motivation letter and the CVs and an interview before the CELL executive board makes a decision.

We would like to extensively interview a selection of high potential candidates before we recruit them, keeping in mind that we are an organisation run by volunteers themselves, and that therefore we cannot realistically contact all candidates.

We would like to ensure the best possible match between CELL and the volunteer, in order for the volunteering time spent with us to be mutually beneficial, inspiring and positive. Please send in your CV as well as a personal motivation letter until 31st May 2019 to . We are not ready to host volunteers under 18!

Volunteer Payment:

Participants of the European Solidarity Corps get their accommodation and public transport within the country paid and receive a monthly compensation of circa 470€. At CELL, they can participate in trainings and seminars for free.


The volunteer will most probably live in a house-share with other European Volunteers. The accommodation will be in a rural area, but with good public transport connections to the city.

Please familiarise yourself with the process of European Solidarity Corps and let us know in your letter whether you have already looked for a sending organisation:

Our PIC 935599921

Looking forward to your application!

Review of our Workshops

The month of September was dark and damp – or at least our workshops were. Despite the blazing sunshine outside, a sizeable group of curious minds gathered to learn more about innovative uses of mycelium and the perks of having an underground larder.

Maurizio giving us a crash course in the diverse and fascinating world of fungi

On 23rd September, Maurizio Montalti from the Italian company Mogu held a 1-Day workshop in the FabLab in Differdange. Mogu is a pioneer in the field of growing bio-material for construction and other things like leather using mycelium, the vegetative part of fungi. 19 interested participants (even some from Namur and Karlsruhe) got to know all stages of the mycelium growth, from the first thread-like fungal hypha to the dense, finished product.

After a quick introductory crash course in the technology that Mogu works with, all participants were ready to get their hands sterile, and then dirty: propagating “starter mycelium” in petri dishes, pasteurizing straw and corn starch (which our fungi would feed on) and preparing already colonised organic material for our own mycelium xperiments. Using 3D printers and a thermoformer, various artistic objects, lampshades and tiles and were quickly manufactured and served as moulds for the mycelium to grow in. Rodolfo Baïz (Fablab) and Rodrigo Vergara (Äerdschëff) built a low budget incubator that created the perfect conditions for the mycelium to thrive in. Some of the artworks grew particularly quickly and were ready to be “baked” in the Fablab oven after only two weeks (people must have thought we were baking some Pizza Funghi). Waiting is the hardest part, but soon we will hopefully see fungtastic results.

Tina (centre) and Mrs Block (left) in her earth cellar

A week later, the Austrian architect and earth cellar-expert Tina Wintersteiger came for a two day event to show us how teaming up with the elements can save a lot of energy. In her presentation on Friday September 28th in the Beckericher Millen, we learned about different clever storage options for all manner of garden-produce. The concept is simple and has been used for millennia: a dark space that is surrounded by soil as much as possible, in combination with strategic ventilation creates the stable temperature and humidity that fruits and vegetables need to stay crisp for up to two years. Having visited many community gardens, smallholdings and commercial farms in Austria and Germany, Tina presented us a whole inventory of unconventional ideas for earth cellar-inspired storage solutions. Most of us, for instance, were not aware that with a few little tweaks, already existing rooms in the house can become a suitable storage room for certain vegetables.

The next day (Saturday), a group of 12 highly motivated people met for the workshop that gave us the opportunity to ask in-depth questions about our own storage-plans. Every participant sketched their living situation and discussed the different options with the group and Tina. In the afternoon, we visited the earth cellar of Mrs Block in Calmus that she had built and used successfully with her family.

The idea behind both these workshops were directly related to the Äerdschëff – we wanted to get to know materials and techniques that will be implemented in it, while also spreading innovative concepts and potentially find willing volunteers for the Ä-project.

Thanks again to all participants and course instructors for the insightful and inspiring workshops!

Ever wondered how they stored food before electricity?

with Architect/Earth cellar expert Tina Wintersteiger (A)

Tina Wintersteiger is an architect and gardener in community gardens. For the book “Basiswissen Selbstversorgung aus Biogärten – Individuelle und gemeinschaftliche Wege und Möglichkeiten” by Andrea Heistinger she carried out building surveys and interviews and gathered knowledge about practices and (construction) techniques around the topic of fresh storage in earth cellars and external storage. Her office “Bauteiler” in Vienna (with Ing. Peter Kneidinger) offers among other things planning services for the construction of earth cellars and other naturally air-conditioned buildings.

Lecture about earth cellars at 19h at the Millen in Beckerich.
The lecture will be held in german (we are working on a translation into French).

Practical workshop and visit of an existing earth cellar in the afternoon.

In the planning workshop Tina Wintersteiger would like to respond to the questions and ideas of the different participants.

In small groups everyone will reflect on their own starting point. In a next step we will compile the results and collect topics. Subsequently we work solution-oriented on the topics and specific questions.

The aim of the approximately 4-hour-long practical workshop is that each and every participant can go home with a more concrete idea about their personal earth cellar, like how much storage space is actually being needed, which type of building fits in their context or how big their construction should be.
