Come tradurreste "located close to concentrations"?

"To complicate matters, obtaining permits for lead smelters has become increasingly difficult, and smelting plants are generally expensive to build and operate. Consequently, profitable operation of smelters is a function of scale. As such, there is a drive towards larger and more centralized smelters, which is at odds with the logistics of the LAB industry that favors distributed recycling and production located close to concentrations of LAB use."


Grazie!
