As a result of climate change, more ecological building materials are continuously developed and find their way into the construction industry. These new building constructions also require new manufacturing technologies. Using examples from research and industry show how partial and complete automation can be used for the practical and individual series production of facade elements made of new building materials such as carbon concrete. The focus is on the complete internal production of some subcomponents. Thus, on the analogy of the production of steel reinforcement onsite in the precast plant, reinforcements made of textile-based materials can also be produced individually in a circulation process down to batch sizes of one without trimming and therefore without waste. The dependence on intermediate product manufacturers can be eliminated and supply bottlenecks avoided. This rethinking of their plant production enables precast producers to manufacture economically and ecologically optimized reinforcements from carbon fibers and integrate them into their circulation process. This adapted production of semi-finished and finished parts made of carbon concrete is implemented similar to the production of precast reinforced concrete elements on existing plant components. Here, too, examples from research and industry are used to demonstrate the need for adaptation in the conventional manufacturing process.
