I finally got around to watching the video and some parts of it didn't make complete sense to me.
Firstly I don't know what the restaurants are like there, but most of the ones I've been to the chopsticks end up pretty much covered with sauce and food. I've rarely seen used chopsticks looking like they're new with no globs of food or waste thrown in with them. I wonder if the restaurants are cleaning them before they bag them?
The process seems strange though as others have commented, coating them with resin and then roasting them to kill germs, then they break them all apart laying them in a tray where a press applies pressure to compress them into blocks. If they were roasted after the resin treatment, and then broken apart, how do they stay in a block instead of just falling apart? They aren't fused at the cellular level, and the resin should be cured by the earlier processes, so I think there must be some steps missing.
I do really love the idea of recycling though as I really can't stand waste of any kind, so I think it's great companies like this are doing that, it is getting increasingly important. Although I must admit from the short video this company is extremely labour intensive.
