The Queen Elizabeth Olympic Park in London has been celebrated as an exemplar of sustainable landscape architecture and regeneration. Yet tracing the new materialist histories of its enmeshed soils reveals how complex sustainable landscape architecture is. On the one hand, the park has expertly recycled and locally sourced its materials. On the other, the socio-ecosystems of its soil assemblages have been pulverized, treated and mixed to create a new profile of synthetic geological strata. Their history and life have been erased. The subterranean sections through this park are caricatures of a ‘sustainable Anthropocene’. Here, the anthropogenic geology supporting the vision of idealized future ecosystems is used for the global marketing of a nation and property developments. This project indicates a destructive systemic blindness in sustainable approaches and the need for truly regenerative design processes, based on working with a place, including the various (other-than) human inhabitants, instead of solely mining its materials to create a perfect vision anew.
