The Total Cost of Ownership (TCO) includes the initial price, shipping, installation, and ongoing maintenance costs (specifically blade sharpening and replacement).

Furthermore, consider the scalability—can the shredder be integrated into a full recycling line (including steel wire separators and fiber granulators) as your business grows?
