Building without waste: A AI project revolutionizes the construction site!

Building without waste: A AI project revolutionizes the construction site!

As part of the EU project "ReinCarnate", the construction sector is lifted to a new, sustainable level. The project aims to promote the transition to the circular economy in construction and to actively reduce the waste of resources. This can be seen from the information from the Technical University of Berlin

A central component of the project is the development of a comprehensive database by the Swedish company Ragn Sells. This database serves to record all raw materials incurred during demolition work. A AI-based tool that was developed in Germany uses this information to create new building materials from recorded materials. Dr. Timo Hartmann from the TU Berlin emphasizes the urgency to rethink conventional linear construction and implement innovative solutions.

circular economy in construction

According to the Digital Center Rostock , the need for a circular economy in construction has gained importance in recent years. In 2022, the advent of construction and demolition waste in Germany was around 216.2 million tons, which was 54.2 % of the total gross waste revenue. This illustrates the immense amount of raw materials that are used annually; In 2022 alone, around 945 million tons of raw materials were taken, including 550 million tons of building materials.

In order to reduce the removal of new raw materials and waste production, various strategies have been developed, including concepts such as "Cradle to Cradle" and "Urban Mining". The latter considers cities as deposits of raw materials, with 55 % of the materials in buildings, particularly in the construction sector. Digital tools and intelligent material persecution play a key role in enabling resource -saving and low -waste construction.

digital innovations and practical projects

The “ReinCarnate” project is supported by thirteen practical projects in Europe and China, which drives the above -mentioned innovations. The TU Berlin is actively involved in research, which includes, for example, automated and non -destructive dismantling of doors for reuse or the robot -based disassembly of windows for the production of multiple glazing elements. These measures aim to extend the lifespan of buildings and materials and to promote high -quality recycling at the end of life.

In addition, the sample project "Futurebalticbauhaus" was presented, which developed cross-border solutions to reduce CO2 emissions by reuse of components in the Baltic Sea region. Here is also pointed out to initiate further training offers and pilot projects to strengthen the circulatory -oriented construction sector.

The discussion about digital technologies to support the circular economy is reinforced by the promotion call of the Federal Ministry of Economics and Climate Protection (BMWK) launched in January 2024. Project applications for the development or testing of digital solutions can be submitted by March 24, 2025. In this context, innovative digital technologies, AI systems and digital twins are to be developed.

Overall, it can be seen that there are numerous approaches to advance the circular economy in construction. The cooperation between various institutions and companies is crucial to establish a resource -friendly and sustainable construction. This not only promotes environmental protection, but also establishes a sustainable building that has grown to the challenges of the 21st century. The Bundesverband Baustoffe-Steine and Erden e.V. .
