Fit for the future through sustainable construction
Construction consumes significant amounts of resources and is one of the largest producers of greenhouse gases. For that reason alone, social development aimed at sustainability is inconceivable without the essential contributions of the construction industry. The world-leading trade fair bauma will present the diverse approaches in the construction machinery world for sustainable construction. Here are a number of highlights.
Resource conservation
Serial construction uses resources more efficiently than conventional construction methods, since prefabrication takes place in a controlled industrial environment. Material waste can thus be reduced, and quantities calculated more accurately. Production waste and scrap materials generated at the factory can be better recycled. It is also easier to dismantle the buildings at the end of their useful life and to reuse their materials.
Recycled materials can be used for 3D printing of buildings for more sustainability in the construction machinery industry. Research is also being carried out on biobased materials for additive manufacturing.
Horizontal drilling is used, for example, for the construction of gas, water and power lines. Thanks to a recent technical innovation, the drilling mud produced in the process can largely be recycled. The amount of waste is reduced to a fraction, while 90 percent of the process water is recirculated.
During road renewal, old milled asphalt can become part of the new road again thanks to a cold recycling unit set up close to the site.
Decarbonization
bauma 2025 will be dedicating a separate key topic to low-emission alternative drives for mobile construction machinery. Electric solutions additionally prevent exhaust fumes and noise for construction equipment such as vibratory plates, tamping rammers, and screeds.
Construction material manufacturers also support climate-friendly construction. For example, an asphalt mixing plant in Bavaria has been using wood dust instead of heating oil as an energy source since fall 2023.
In addition to conserving resources, serial construction also scores points in terms of climate protection: The standardized production conditions allow energy use to be optimized and reduce carbon emissions compared to conventional construction site processes. In addition, emissions from disposal transport are minimized, since modular construction generates less construction waste on site.
Social aspects
Sustainable construction is by no means limited to resource awareness, recycling of the materials used, and a smaller carbon footprint. Alongside solutions that remain economically viable, safeguarding human health, for example, is also a key objective.
Reducing construction site noise is good for the health of both the workers and local residents. Many municipalities around the world, such as Munich, London, Paris, and Zurich, are boosting the use of quieter construction machinery through guidelines, regulations, and subsidies. E-machines are not only particularly quiet, but also emit no harmful exhaust gases or particulate matter where they are used.
Every bauma presents new ideas from the construction machinery industry to further improve safety on the construction site and the working conditions for employees. These also include ergonomic and intuitive controls, vibration-damping technologies, as well as driver assistance, telematics and overload indicator systems.
