written by Deborah Dull, on site at GreenBiz 2026   I spent today in a room full of people who think about waste for a living. And the word that kept coming up had nothing to do with recycling. It was sovereignty. Here is the situation. The United States imports 95% of its critical mineral supply. Lithium, cobalt, rare earth elements, the stuff inside every battery, every semiconductor, every electric motor. We do not make it, we do not mine much of it, and we do not control the supply chain that delivers it. That is not an energy policy problem. That is a national security problem. Now here is the part that should make you put down your coffee. A ton of smartphones contains dramatically more gold than a ton of mined ore. We are talking about concentrations that make urban mining look like a gold rush compared to digging in the ground. And yet the recovery rate for those materials, once a phone leaves its first owner, drops to around 13%.

To thrive in 2025 and beyond, companies need real-time visibility, predictive insights, and agile execution. That’s where supply chain control tower technology comes in.   What is a supply chain control tower, really? A control tower acts as the command center for your supply chain. It gathers and visualizes data, analyzes disruption impacts, and provides actionable recommendations before problems escalate. Advanced solutions can even automate responses to routine issues and enable cross-functional collaboration to ensure that decisions aren’t just well-informed, they’re executed across the supply chain as well.   Why control towers matter now Supply chain risk isn’t a passing cloud; it’s a thunderstorm that…
