Tomra’s AI integration is impressive, but their pricing seems steep for smaller operations.
Anyone have experience with Feida’s separators? Their Asian market focus has me curious.
Great breakdown! Especially useful to see the voltage ranges for different materials.
The e-waste case study was eye-opening. Didn’t realize purity differences could be that significant.
