Shredding is a good and economical way of securely disposing of personal information. Everyone knows that. Thanks to Boing Boing (via Engadget) for posting a link to SSI, a shredding company that can shred just about anything. The company has posted videos on their site of their industrial grade equipment in action. From electronic media and documents (good for privacy) to washing machines and fridges (cool to watch), there appears to be nothing that can't be shredded.
A gallery of all their demos is here: SSI Shredding Demonstrations
