Riuso dei materiali naturali. Rinaturalizzare il suolo per un'architettura circolare

The paper investigates the role of soil renaturalization and agricultural waste reuse as integrateci strategies for circular architecture. Moving from the Marxian "metabolic rupture,• the text analyzes the impact of extractive capitalism on the soil ecosystem and proposes regeneration as a necessary practice to restore ecological functionality. In this sense, the concept of "resource technology' enhances agricultural biomass-such as straw, husk, chaff, mycelium-as bio-based materials capable of reducing the environmental footprint of the construction sector. Through ltalian and international case studies, the paper demonstrates how agricultural waste can be reintegrateci into construction cycles, outllning a new design paradigm based on the co-evolution between natural and built environments. Architecture thus takes an active role in the ecological transition, contributing to territorial resilience through low embedded energy solutions and landscape regeneration. In this perspective. materials and design processes are confìgured as metabolic devices, capable of reinterpreting the relationships between nature, culture and architectural technology.
