An old material is being rediscovered: flax has been with us for thousands of years in the form of clothing, sacks, and robust ship’s ropes. Now the plant fibres are experiencing a renaissance and could become the building material of the future. Combined with a special bio-resin, it can be made into a light and highly stable material with properties comparable to aluminium or steel. The EU project “Smart Circular Bridge” shows what is possible with this innovative new material: via the development of three bridges from this so-called bio-composite. A first one has now been built, and two more will follow.<\/strong><\/p>\n\n\n\n

Junior professor Hanaa Dahy<\/a> from the University of Stuttgart is involved in the project. As head of the research group for Biobased Materials and Materials Cycles in Architecture<\/a> (BioMat), she specializes in building with bio-based materials. She was able to use this expertise in the development of this high-tech bridge made of flax: “The entire project provides an important impetus for how alternative, biomass-based and annually renewable resources can be used in the construction industry. With the help of these resources, we aim to overcome major challenges such as high CO2<\/sub> emissions and high energy consumption in the production of building materials.”<\/p>\n\n\n\n

In times of climate change and dwindling raw materials, bio-composites offer a great opportunity for the construction industry with its huge CO2<\/sub> footprint and immense consumption of resources. They hold enormous potential for a bio-based circular economy, especially since flax, unlike wood for example, is a fast-growing plant.<\/p>\n\n\n\n

Interdisciplinary teams drive development<\/h3>\n\n\n\n

The first “Smart Circular Bridge” with a span of 15 metres has now been realised by an international consortium of 15 partners led by Eindhoven University of Technology in the Netherlands. The project team consists of five universities, seven innovative companies, and three municipalities. The first bridge set up at the Floriade international horticulture exhibition in Almere, Netherlands will open April, 22. Two more \u201cSmart Circular Bridges\u201d for pedestrians and cyclists will be built in Ulm, Germany and Bergen op Zoom, Netherlands later in 2022 and in 2023 respectively. Through this intensive cooperation between science, industry, and local authorities, a multitude of innovations is launched.<\/p>\n\n\n\n

Apart from the 100% natural flax fibers, the resin will also come from non-fossil sources as much as possible. The proportion of bio-resin is 25% for the first bridge, but it will reach 60% or more for the next bridges. This is achieved by using waste products from bio-diesel production and recycled PET bottles.<\/p>\n\n\n\n
