America's New Material Could Replace Wood Forever

America's construction industry is facing a quiet materials crisis: lumber costs, sawmill capacity, imports, moisture damage, building emissions, and supply-chain pressure are all pushing builders to look beyond traditional wood. This episode examines the new American materials trying to replace wood forever, from rice-hull ACRE boards and Plantd grass-based structural panels to bamboo wall systems, hempcrete, mycelium composites, Ferrock, and other carbon-negative building breakthroughs.
