    Kinda pricey for small operations tho – $95k starting cost is steep.

    Do these systems work for oil filters too? The specs mention HEPA but not automotive.

    Is the ‘low-temp processing’ actually better or just marketing speak?

    That X-ray detection sounds overkill but I bet it helps with quality control.

    How often do the blades need replacing on those shredders? Maintenance cost isn’t mentioned.
