What is the significance of Nextchem's Nx Stami urea technology in the AdvanSix DEF plant project?

Nextchem's Nx Stami urea technology forms the core of the urea-to-DEF plant, providing a nameplate urea melt capacity of 700 short tons per day and enabling a fully integrated process to convert urea melt into diesel exhaust fluid (DEF); this configuration is described as proprietary and represents the first-of-its-kind application for Stamicarbon.

What are the key strategic drivers behind AdvanSix's decision to develop a domestic DEF production facility in Hopewell, Virginia?

AdvanSix aims to meet rising DEF demand—especially in the Mid-Atlantic and Northeast US—driven by stricter NOx emission standards across transportation, construction, agriculture, and industrial equipment fleets; the project leverages AdvanSix’s integrated ammonia platform to enable a reliable, domestic supply chain currently dependent on imports and production from other regions, while supporting flexible product forms and concentrations to serve diverse customer needs.
