Within the construction industry, there is a wish to renovate with less climate impact. But there is a lack of enabling solutions. When renovating buildings today, we still use materials and manufacturing methods that are not resource efficient. To improve the renovation practice, we need new solutions.

In this project, we are developing a new environmentally friendly material that can replace the less sustainable materials based on synthetic, non-renewable and fossil resources, such as sand, clay, minerals and metal ores. The material consists only of natural raw materials: baker’s yeast, cellulose fibers, algae, plant-based sugars and water. All those raw materials can be found as byproducts from food and forest industries.

To apply the material in renovation at the full scale of a building, we use robotic 3D printing. This technology contributes to the resource and energy efficiency of our solution by not generating any waste and by using little energy to renovate building elements with our material.
