The main reason I was on board with trying it was to reduce the amount of food scraps we threw away in the trash can (we do not have a garbage disposal). I was raised in a house with a compost pile, so it is second - nay, FIRST - nature for me to want to put orange peels and egg shells somewhere other than the garbage. (It's the same as if you grew up recycling in your home - you will never be able to throw away a newspaper in the trash can without wincing.) And I'm happy to say that the Bokashi bin has performed very well on that count. Almost anything can go inside the Bokashi bin, including cooked food and small pieces of paper (like napkins), which is more than you can say for compost piles. It is so easy to keep the bowl nearby as I'm prepping dinner, fill it with peels and skins and scraps, and then add it to the big sealed bin at the end of the day. Our kitchen trash can doesn't fill up as fast and it doesn't get as stinky, either.
But of course, the main purpose of the Bokashi bin is to create humus for enriching the soil of a garden. That's the main reason Jeremy tried Bokashi in the first place. You have to wait for the entire bin to fill before you bury it in the garden, and in the six months since we've had the bin, we have done that three times. We are still on our original bag of Bokashi bran, by the way, which is nice since I was reluctant to be locked in to buying a proprietary product too often. We have also used the "juice" of the bin as plant food. And it seems to be going well. Considering that our soil was pretty much sand before, I'm sure the Bokashi humus is improving it.
The only negative I can report about the Bokashi bin is not really its fault. Sometimes, we get lazy and forget (or "forget") to empty the day's food scraps from the bowl on the counter into the sealed Bokashi bin. That's fine if it happens one day only, but sometimes the counter bowl gets left unemptied for too long. This is a problem for two reasons. First, it starts to stink (because hello, nasty food scraps just sitting in a bowl on your counter). And second, mold sometimes starts to grow, and once the food is moldy, you cannot add it to the Bokashi bin. It messes with the healthy fermentation process.
Overall, I would really recommend Bokashi for people who cannot (for one reason or another) manage a normal compost pile - or even if you can, actually. It takes up very little space, doesn't require much effort (ahem, unless you get lazy like us sometimes), adds back to your garden, and reduces the amount of food scraps you throw away in your trash can. And that's good for everyone.
