The Hidden Footprint: Confronting the Environmental Costs of Nanomaterial Production
Nanotechnology is widely promoted as a cornerstone of sustainable industry, enabling cleaner energy, more efficient filtration, and reduced material waste. Yet the processes used to manufacture nanomaterials at scale often carry substantial environmental burdens of their own — from hazardous solvent use and energy-intensive synthesis to unresolved questions about nanowaste disposal. As production volumes grow, the sector faces a reckoning it has been slow to acknowledge.
