Mountains of Residue depicts a mountain formed from countless plastic particles — a terrain rising out of debris, where waste becomes landscape and the remnants of consumption solidify into a new kind of earth. Created as part of Carague’s speculative design project Maria Islands, the work imagines a fictional Philippine island composed entirely of imported plastic waste. Set in a future where the Philippines expands its territory by reclaiming trash exported from the West, it reflects on post-colonial environmental entanglements and the politics of territorial imagination.
