From the video description, provided by Fraser Valley Farm:
"I prefer Bokashi fermentation over hot composting of kitchen waste for a number of reasons, which I'll outline here. I'll also show you how the system works, and how to build your own DIY Bokashi bucket system. "
With Bokashi you have to spend money for the additive to make it ferment. That’s why I don’t use it. Vermicomposting works in small spaces but you can’t put much in it unless you have a large worm farm, in which case it takes more space than a compost bin. It also doesn’t produce as much compost as a regular compost bin, but the quality could be better.
