Conference highlights the opportunities and challenges of circularity
Participants at the fourth Kästli symposium called for courage to embrace a circular economy in the construction industry. The industry should think in terms of generations and take responsibility.
The Kästli companies have organised their Kästli symposium for the fourth time. According to a press release, around 100 experts and interested parties discussed the circular economy in construction at the Rubigen gravel pit.
The construction industry already recycles 70 percent of its approximately 75 million tonnes of construction waste every year. But: “Circularity is more than just recycling,” said Susanne Kytzia from the OST – Eastern Switzerland University of Applied Sciences, according to the press release. The circular economy must strike a balance between many different interests. Many small decisions together could make a big difference.
Patric van der Haegen from Eberhard Unternehmungen pointed out the high ecological and social costs of a purely profit-driven approach. “This makes it all the more important that we as an industry take responsibility now and set a new course.” Pascal Remund from host Kästli called for cross-generational thinking. “We need to think and act with foresight – in the interests of those who come after us,” said the Chairman of the Management Board of the family business, which will soon be 140 years old.
Michael Widmer, Managing Director of the Swiss Building Materials Recycling Association (BKS ), also believes that politicians and the administration have a duty in this regard, especially when it comes to public procurement. However, all those involved in the construction industry also need courage, according to the participants. This ranges from building owners, planning companies and construction companies and also includes the scientific community. “The circular economy is not a goal, but a path on which we are constantly learning,” said Pascal Remund. “It is crucial that we act now – together and courageously.”
