How do we hold each other through a change of phase? This is the seminal question asked in this thesis as it explores networked systems populated by urban metabolisms and waste streams. Using an embodied feminist framework, this paper attempts to highlight short comings in the current treatment of road snow sludge in the metropolitain areas of Stockholm, Sweden and proposes the use of a systemic, intergrated mycological strategy to filter and detoxify snow-melt-water before it re-enters natural bodies of water.
