'Zero Waste to Energy' appropriates part of a massive industrial complex to embed values of circularity and act as a seed of change. Storytelling, Material Flow Analysis and design come together to create a parasitic architecture, which weaves a vertical urban campsite and chapel into a chimney of the Netherlands’ largest Waste-to-Energy plant. Framed as the end point of a spiritual pilgrimage, the intervention reconciles the city with its industry, and society with its resources.
