RE:in-house processingMaybe,
Drosrite is not a plasma based system so power costs are not a big deal. It is heated by a chemical reaction. One of the major cost savings with drosrite is not having to ship the material offsite. It’s bulky and toxic. Recovering the metal on site is by far the most cost effective method. Link below provides info on toxicity of aluminum dross particularly if it comes into contact with water.

This is an taken from PYR paper on Drosrite
”With DROSRITE PLUSTM, hot dross is charged to a refractory-lined rotary furnace, immediately after skimming from the aluminum or zinc holding furnace. The DROSRITE PLUSTM furnace is sealed and maintained under an argon atmosphere. The only heat source for the furnace is the controlled reaction of oxygen with unrecoverable metal contained in the dross residue, after the recoverable metal has been tapped. After each treatment cycle, the residue is discharged except for an amount which, when heated at 1000°C for aluminum or 800°C for zinc, will hold enough energy to heat the next batch of dross to the required temperature.”
