In the design of the park, we reused several whole parts from other building sites. We utilized an old Split from the SBB as a gravel infill for the wall. We also took an old staircase that was at the West side of the site and reused it. 

Below, we highlight the sustainability considerations and the potential social economic impacts of the proposed technologies are highlighted. The developed process uses highly sustainable and locally sourced material, enhanced by digital design and fabrication methods. As illustrated, the construction of the dry stone retaining wall will utilize “Findlinge” or upcycled concrete. For retaining walls in particular, previous research has suggested the sustainable advantages of masonry benchmarked against concrete in terms of CO2 consumption and energy footprint (source) . Significantly, dry-stone masonrysurpasses these performances, considering the construction process can take advantage of locally sourced materials, and the structures are produced without mortar and are thus primarily reversible. Additionally, the developed method of construction can incorporate recycled concrete aggregates and thus could be used to upcycle a portion of the estimated 2.6 million tons of concrete recycled each year from demolished houses. Here in Zurich for example, this has particular significance, the approved landfill volume for recycled concrete will only be sufficient for the next ten years.

Moreover, in collaboration with Eberhard, several other ecological materials are integrated into the construction of the planned demonstrator. The Benches throughout the park are made from zirkulit®, a concrete developed by Eberhard which is currently the most circular concrete of the world (source). The split for the backfill of the wall will be recycled from railroad sites, and the stairs integrated on the south side of the demonstrator are re-used from another industrial site.
