Cellulose aerogel produced at pilot scale!

Last week, the aerogel-it team could celebrate reaching several milestones. Alberto has single-handedly achieved production of 1000 liters of cellulose bioaerogel beads using our pilot plant at Hamburg University of Technology!

Why is this important to us?

1️⃣ It is likely the largest quantity of bioaerogel ever produced. Alberto may very well have achieved a world record – especially since he did it completely on his own!

2️⃣ Much of the cellulose bioaerogel is required for our BIOVIPWALL project as part of the iclimabuilt (an EC Horizon Europe project). It will be converted to bioaerogel vacuum insulation panels (VIPs) by our partner va-Q-tec. Some bioaerogel VIPs will undergo testing by the project partners, and most will be integrated into carbon-reinforced sandwich elements. With this, we want to demonstrate one of the slimmest wall designs possible while using bio-based superinsulation!

3️⃣ The cellulose bioaerogel is also relevant for bioaerogel VIPs in new, more lightweight logistics solutions as well as greener cooling appliances (replacing for example fumed silica).

4️⃣ Based on the learnings he made, Alberto could validate and further improve his process concepts and equipment designs. This is highly important for scaling to our first large production plant. What is most amazing: Almost all of his designs work exactly as he planned.

It seems hard to believe that a year ago we could only produce a couple of liters at a time in the lab. Now we have reached a whole different level. We will be able to serve our customers with much needed pilot-scale quantities for their testing and showcases.

Meeting for CO2-optimized Construction for Roads and Paved Surfaces at DBU

Recently, Marc presented our aerogel-it activities and products at the meeting for CO2-optimized construction for roads and paved surfaces (CO2-optimiertes Bauen von Verkehrsflächen & Straßen). The meeting took place at the DBU Deutsche Bundesstiftung Umwelt Umwelt in Osnabrück.

Michael Hafemann and Mark Gieseke of Gieseke Gruppe expertly moderated the event after Prof. Markus Große-Ophoff of DBU, Mark Gieseke and Prof. Dr. Prof. Dr. Heiko Meinen of Hochschule Osnabrück had kicked it off. The speakers highlighted roads and paved surfaces as very important but often overlooked lever for CO2 savings. Next to buildings they make up a large share of the built environment and cause corresponding CO2 emissions during construction and repair.

There were excellent presentations on decarbonization e.g. of bitumen and concrete by B2SQUARE and CarStorCon® Technologies. Stephan Harnischfeger of MHI Baustoff GmbH explained the challenges around asphalt emissions and low-temperature asphalt products as important solutions. ecopals, ecoLocked, HeideHanf and Bundesanstalt für Materialforschung und -prüfung also gave presentations. Furthermore, there were keynotes by Dr. Martins Zaumanis of EMPA and Prof. Dr. Hans-Hermann Weßelborg of FH Münster.

Aerogels also play a role for CO2-optimized construction in this field and are already being investigated for more thermal-resistant roads and paved surfaces. One example are our US colleagues from aerogel Coating Technologies (aCT Inc.).

Great discussions in the networking sessions rounded off the event. As former DBU Green Startup, we were certainly happy and thankful to have this opportunity to be back at DBU. Thank you very much to the organizers for inviting us.

New team member Eduard Siemens

We are very happy to share that the aerogel-it team has grown! As of January 2025, Eduard Siemens joined our team as Sales Director.

In addition to being a Sales expert, Eduard is an experienced founder himself and built a highly successful 3D-printing company, EWOQE, from scratch. With his business running stably, he was looking for new challenges to pursue and found our work and mission. He was intrigued by our aerogel materials and potential they offer and contacted us to see if we could work together – which we immediately accepted.

It goes without saying that his founders experience and Sales skills are invaluable to us. In his first two months, Eduard has already managed to open up lots of exciting opportunities. We are honored to have him on the team!
