Technical Moat
MediumThe chemistry is established, but the moat is Radioactive Waste Management and Global Environmental Compliance. High standards in China, Malaysia, and the West now mandate sophisticated tailings encapsulation and zero-discharge systems. The barrier is the massive capital and engineering required to meet these non-negotiable environmental 'licenses to operate'.
