Intensified climate change, limited natural resources, lack of professionals These are issues that the global construction machinery industry must pay attention to. At the same time, the application of more advanced construction technology and materials will become one of the effective ways to solve the above problems. Bauma exhibition in Germany will be held in Munich from October 24 to 30, 2022. At that time, Bauma officials will comprehensively introduce the latest technologies and major development achievements in this field.
In fact, the production and processing of building materials, the construction process itself, and the maintenance and demolition of buildings and other infrastructure will lead to a large amount of carbon dioxide emissions. For example, cement, as one of the commonly used building materials, accounts for 8% of the global carbon dioxide emissions in the production process. Chatham House, a British think tank, said that if the cement industry is regarded as a country, it will become the third largest carbon dioxide emitter after China and the United States. Among them, one third of the carbon dioxide emissions come from the combustion of fossil fuels such as coal and oil, while the carbon dioxide released during the decomposition of limestone accounts for the largest proportion.
CCU and CCS in cement industry
Christoph Danner, an expert on construction machinery and building materials from the German Federation of machinery and equipment manufacturers (VDMA), said: "if we want to greatly reduce carbon emissions in the cement production process, we need to carry out a series of fundamental technological changes." In his view, "carbon dioxide capture" is a scheme with great potential and feasibility, which can be used (i.e. carbon capture and utilization, CCU) or safely and permanently stored in deep geological strata (i.e. carbon capture and storage, CCS). Dana said, "in this way, 95% of the carbon dioxide in the cement production process can be captured, which can turn waste into treasure while realizing green production." At present, the first carbon dioxide capture facility for cement production in Germany, located in roldorf, has been basically completed. It is expected that the system will be put into operation in the near future, which can capture two tons of carbon dioxide per day and provide raw materials for other chemical industries.

Save resources through recycling
In addition to taking measures to protect the climate, the construction industry also actively calls for saving raw materials. Sand is the most widely used building material, but now it has become increasingly scarce and has become the focus of public attention in recent years. The solution of recycling sand is to use modern crushing and screening technology to treat construction solid waste materials on site for new construction projects, so as to realize reuse. Alexandre Marchetta, President of the European Commission for construction equipment (Cece), said: "this plan will not only reduce the pressure on natural resources, but also help reduce material transportation, greenhouse gas emissions, noise and air pollution in densely populated urban areas, killing many birds with one stone."
Modern technology makes the construction machinery industry more attractive
How to further improve production efficiency is a common challenge facing the global construction machinery Renaissance. "Due to the lack of professional and technical personnel, only through more manpower can not effectively solve this problem." Tim Oliver m ü ller, general manager of the German construction industry association (HDB), said, "On the contrary, we should focus on intelligent construction technology, product innovation and artificial intelligence auxiliary system. It happens that young people are fascinated by these fields, which can not only improve productivity, but also improve the overall charm of the industry. Among them, modern construction machinery also plays an important role. Thanks to the increasing intelligence and comfort of the cab, more and more apprentices begin to learn to drive construction machinery, which is construction machinery The main reason why the industry has become attractive again. "
Describe the future intelligent construction scenario
For a long time, the goal of the construction machinery industry has been to produce the same or even more products with fewer employees. Christoph Danner, an expert of the German machinery and Equipment Manufacturing Association (VDMA), said: "to achieve this, the continuous construction and 3D printing technology of concrete are indispensable. The continuous construction mode that has been used for many years has been very mature. The application of a large number of prefabricated finished building modules makes the construction site only need a few construction workers. More and more advanced additive manufacturing technology (3D printing) It will also have a similar effect and save a lot of labor. "
One of the key themes of Bauma 2022
"Future construction technology and materials" is one of the key themes of Bauma. As the world's leading exposition of construction machinery, building materials machinery, mining machinery, engineering vehicles and equipment, major exhibitors will enjoy displaying their latest solutions. Bauma forum also provides you with an opportunity to discuss current trends.
