Architecture's Extractive Supply Chains: Sand, Marble, and Lithium

A critical analysis by Diogo Borges Ferreira, published on ArchDaily on July 17, 2026, examines the hidden politics of material extraction in architecture. The article traces the global flows of sand, marble, and lithium, revealing how construction materials are tied to violence, displacement, and environmental destruction. Sand, the largest extraction industry by volume, fuels illegal trade worth $200-350 billion annually, with conflicts in India and Southeast Asia. Marble extraction in Carrara, Italy, has accelerated dramatically, with labor exploitation and environmental damage. Lithium mining for clean energy batteries depletes water in South American salt flats, affecting Indigenous communities, while cobalt mining in the Democratic Republic of the Congo involves child labor. The piece argues that architecture's focus on material performance ignores the territorial and human costs of extraction.
