You might be right (first time for everything), but it would very much depend on what the yield is, and what the cost and longevity of the "proprietary" liquid is, and how difficult/costly it is to dispose of.
If it were profitable, they would be loaded up with work, it did not look like they were, it looked to me like someone got public finding to build a facility and develop a process.
The plastic is worthless, and the steel is virtually worthless. Scrap value of the Al is about $2K a ton, the Cu is about $800 and the Ni about $15K a ton. And at the point in the process shown in the video, these are nowhere near scrap value.
A proper end of the process would be stacks of clean ingot, which we are not shown.
