Last week, Marc supported by Eduard and me pitched aerogels for slim construction at the REALPitches of the REAL ESTATE ARENA 2025 in Hannover!

Marc highlighted how aerogel superinsulation materials can help to address pressing needs of the Construction industry:

  • Space-saving, slim construction with thermal superinsulation is highly relevant for energetic renovation to conserve interior living space where exterior insulation is not possible e.g. in heritage buildings.
  • Thermal superinsulation also brings value to new buildings where additional living space can be created from an overall slimmer wall design.

Lots of exciting proptech companies pitched over the course of the event:

  • It was great to see the progress TRIQBRIQ have been making with their wood-based construction system.
  • CompositeEdge presented an incredibly thin acoustic insulation material based on their composite technology.

Important topics of the exhibition were decarbonization and sustainability, as well as much-needed digitalization of the Construction industry. Talks and panels of the REAL Future Conference reflected this:

  • In a great talk, Daniel Schreiner of Purpose Green highlighted the massive challenges Germany is facing with the current energy-inefficient building stock and the huge effort required to renovate it.
  • This is also becoming a financial challenge for owners, since increasing CO2 taxation (e.g. EU ETS 2) will significantly drive up energy costs – mostly for them.
  • Plus, energy-inefficient buildings lose value. And banks will increasingly move away from financing of such buildings.
  • Panelists furthermore discussed the unreliable legal framework, lack of digitalization and lack of the required trained workforce as additional challenges.

All in all, the aerogel-it team confirmed their vision of more sustainable and more affordable aerogel superinsulation materials. We are pushing hard to scale our solutions to contribute to these urgent needs.

A big thank you to blackprint for inviting us to the event!

We are happy and proud to share an important milestone today: The first 40l of lignin bioaerogel granules were produced on the bioaerogel pilot plant at the Hamburg University of Technology. The production formed part of the currently running commissioning project.

This may be a world record: To our knowledge, it is the biggest quantity of bio-based superinsulating material that has ever been produced. So far, everything we have seen or done has only happened at lab scale – including our own work.

We are extremely proud of Alberto and Raman who made this step possible. And we are very thankful to Hamburg University of Technology and Prof. Dr.-Ing. Irina Smirnova for hosting us.

The pilot plant will have a daily capacity of up to 200l of bioaerogel granules. With this increase of scale, we achieve two things:

  1. We will now transition towards larger-scale prototypes and showcases with our partners e.g. in the Construction or Logistics spaces.

  2. We are also validating our step-change process technology for more energy-efficient and cost-saving aerogel production which is the foundation for our first production plant.
