Capability profile
Exterra's ARC regenerates acid and base within mineral-processing flowsheets. LOW combines it with hydrometallurgical recovery, while ROC converts suitable oxides into stable carbonates near an emissions source.
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
The SGS collaboration announced in March 2026 provides modular pilot and analytical work in Quebec City, Lakefield and Burnaby. It describes Hub I as pre-commercial and independent validation as planned, rather than documenting an operating full-scale plant.
Partners can commission feedstock-specific testing and flowsheet development, with scale-up and licensing considered as project evidence matures.
A technology readiness level is not established by the reviewed public sources.
No reviewed Mission area or released Defence need connection is currently published.
These records support this capability and its published Mission area and Defence need connections. A source count is not a count of independent confirmations.

Supports: Capability · maturity
SGS's March 2026 announcement describes Hub I as pre-commercial and plans independent pilot validation of Exterra's reagent-regeneration proposition. The collaboration places modular pilot and analytical work at SGS facilities in Quebec City, Lakefield and Burnaby. The pathway is testing, optimization and scale-up toward commercial readiness, rather than an already-qualified full-scale plant.
