In this episode, we explore the world of phosphoric acid production with guest expert Francesco Onori from Cavart. From the origins of phosphatic sands to the large‑scale industrial plants that transform them, we dive into the engineering, logistics, and machinery behind this essential chemical. We uncover how transport systems, conveyors, and reliable components like those from Rulmeca keep these complex processes running, and why phosphoric acid is vital for global agriculture, fertilizers, and everyday products. A clear, engaging journey into chemistry, safety, and the future of industrial engineering.
