Similar to factory modules in usage are refineries, however they principally take in one input material and output a processed version of that material, while also costing fuel (and perhaps other commodities) to run. These are more 'jobs' than one-time crafts, and most are set to auto-repeat unless explicitly told to run once.
Except for the refinement of Uncharted commodities, these recipes offer discounts to certain IFFs, which require less input volume and time for the same output.
