  • Ecocycle technology from Holcim receives award

    Ecocycle technology from Holcim receives award

    Holcim’s Ecocycle technology has been named a “beacon of the circular economy in the built environment”, according to a press release. This was announced as part of a joint initiative by the consulting firm McKinsey & Company and the World Economic Forum at its annual meeting in Davos. The award recognises pioneering solutions that demonstrate a novel, unique approach to the circular economy, proven and substantial impact of high value, and significant scale and maturity.

    Holcim already operates over 100 of its Ecocycle recycling centres. According to their own figures, they recycled almost 7 million tonnes of construction waste into new building solutions in 2022. This corresponds to over 1,000 lorry loads per day. This network is to be expanded to 150 locations by 2030. In Europe alone, the Group plans to recycle over 20 million tonnes of construction waste. Ecocycle makes it possible for concrete, cement and aggregates to contain between 10 and 100 per cent recycled demolition materials without compromising on performance.

    “With our advanced recycling of demolition materials, we can already reduce the carbon footprint of cement by up to 40 per cent,” Holcim’s Head of Sustainability Nollaig Forrest is quoted as saying. “This is just the beginning. With our innovations and partnerships along the entire value chain to further develop building standards, we want to accelerate the transition to circular construction in all the urban centres in which we operate.”

  • Swiss premiere 100% recycled aluminium for Green Metro Campus

    Swiss premiere 100% recycled aluminium for Green Metro Campus

    This is the third project in Europe and a first for Switzerland. Green has teamed up with Implenia, Ernst Schweizer and Hydro Building Systems to implement this innovative solution. The use of recycled end-of-life aluminium leads to a significant reduction of the CO2 footprint by a factor of 40 and more than 167 tonnes of CO2 emissions are saved.

    The 100% recycled aluminium is used in the façade elements and reduces the CO2 footprint by a factor of 40 compared to primary aluminium, without compromising on quality. Roger Süess, CEO of Green, explains: “We are constantly exploring innovative ways to use new materials and are delighted that we have succeeded in doing so in collaboration with our partners.”

    Aluminium is considered a pioneering material for sustainable construction due to its strength, lightness and durability. It can be recycled almost indefinitely, using only 5% of the energy required to produce primary aluminium. Due to these excellent recycling properties, aluminium is already seen as an important part of a circular economy and its importance in the construction industry is expected to increase.

    The façade elements for the new office building will be manufactured by Ernst Schweizer AG, while the aluminium will be produced by the Norwegian Hydro Group. This is currently the only manufacturer that can produce high-quality 100% end-of-life aluminium without the addition of primary aluminium and with a near-zero CO2 footprint. Although recycled end-of-life aluminium is currently available in small quantities and is associated with higher costs, the four partners are setting an example by using this promising material in Switzerland for the first time.
