Agreed. It's the complete job that matters, not just the initial crunch. If the machine has to stop, reverse, then continue, I want to see it. It's not a 'failure' - it's all part of the process. The sequence at 7:25 was disappointing. I wanted to see how the hardened gears were broken up - whether they cracked or crumbled or exploded. Maybe the video maker is worried about losing viewers by showing the various shredders taking more than one pass to destroy things. That's a pity. I'd much rather see the complete process.

I don't think that ALL those articles are still useful, besides, in this day and age of consumption they need as much raw materials they can get in order to produce more
