  • Sustainable circular economy in the construction industry

    Sustainable circular economy in the construction industry

    One of the key challenges facing the construction industry is the reduction of CO2 emissions. By decarbonising processes and procedures in the gravel, concrete and recycling industry, companies can make an important contribution to sustainability. The autumn event offers an industry roadmap to help companies identify and implement sensible measures to reduce emissions.

    Optimising concrete as a building material for sustainable construction projects
    Concrete is still one of the most widely used building materials in the world. However, sustainability also plays a decisive role here. The autumn event will show how the sustainability properties of concrete can be optimised and used in a targeted manner. At the end of a building project, the question arises as to how materials can be reused. Options such as renovation, refurbishment or recycling offer sustainable solutions, which will be discussed at the event.

    Pollutant control and separation as the basis of the circular economy
    A successful circular economy requires the targeted separation and control of pollutants. This begins with the planning of a construction project and continues with material treatment and disposal. At the autumn event, the key aspects of pollutant separation will be explained, which are essential for achieving sustainable results in dismantling projects.

    Dealing with persistent substances such as PFAS
    Per- and polyfluorinated alkyl compounds (PFAS) are a group of persistent substances that are increasingly becoming the focus of environmental research. These substances are ubiquitous and pose a particular challenge in the circular economy. The autumn event will provide insights into the possibilities and limitations of dealing with PFAS and highlight solutions that can be implemented in practice.

    Innovative decarbonisation projects in practice
    A highlight of the autumn event is the presentation of the world’s largest electric melting furnace for rock wool. This innovative project shows how decarbonisation is implemented in practice and what potential lies in the production of stone wool. Experts will gain practical insights into the technical developments and their contribution to a sustainable circular economy.

  • Basel processes chemically contaminated building materials

    Basel processes chemically contaminated building materials

    Building materials from the Basel region should in future be processed and recycled in the local building material cycle. Baustoff Recycling Nordwestschweiz AG, a joint venture between Holcim Kies und Beton AG and Antag Recycling AG , founded in August 2020, wants to build a processing plant in the Birsfelden state mine. The former gravel pit is easily accessible by rail, road and the Rhine and is located next to the tunnel portal for the planned Rhine tunnel on the Basel eastern bypass.

    The plant in Birsfelden should also be able to process excavated material with the highest chemical pollution level. The processed gravel is then to be further processed in the neighboring concrete plant of Holcim Kies und Beton AG. A total of two thirds of the material should flow back into the building material cycle.

    The canton of Basel-Stadt surrenders part of its state mine under construction law for the plant, he writes in a message .
