The Bristol-and-Lisbon climate-tech firm is scaling MykoFoam, a carbon-negative mycelium insulation panel grown from industrial residues at its Portuguese pilot plant.

Mykor, the Bristol-headquartered climate-tech firm growing carbon-negative building insulation from mycelium and industrial farm waste, has raised €4.6m to scale its production.

The round is roughly four times the size of the company’s previous funding total and is the largest single capital injection it has taken since founders Olivia Page and Valentina Dipietro started the business in 2021.

Mykor’s product is one of the more visually unusual things being scaled in European climate-tech right now.

MykoFoam, the company’s flagship insulation panel, is grown rather than manufactured: agricultural residues from the company’s Alentejo region in Portugal are inoculated with fungal mycelium, which threads through the waste material and bonds it into a rigid panel over roughly four weeks.The 💜 of EU techThe latest rumblings from the EU tech scene, a story from our wise ol' founder Boris, and some questionable AI art.
