Bokashi Bin Exploding

WeZ asked 2 weeks ago

Hello,
I can’t seem to find help on this with my first bokashi
My bokashi bin swells and explodes the lid off if I don’t let some air out. 
i have no maggots, no bad smell, nothing appears wrong except within a day or two the bin will burst open if I don’t let out some air. 
it has taken me about 5 weeks to fill the bin and the fuller it got the more frequently needed to be ‘burped’.
another strange thing is there has never been any tea at the bottom. no liquid is forming. 
i must be doing something wrong, please help – I keep worrying it pops when I’m not home and I wont notice the open bin which will attract flies etc.
Ciao

Hi WeZ,
The bokashi fermentation process should not produce any gases. It is an indication that some putrification is happening in the bucket and things are starting to go bad. 
From your explanation it doesn’t sound like the batch has failed (yet). Tea, or lack of it, is not an indicator is success or failure.
Its likely that there is a small pocket of rotting food. Maybe a large piece of food waste that was not chopped up small enough or an uneven spread of bokashi bran. Not enough to smell bad, or make the whole bin fail (yet) but enough to produce a bit of gas to make the bucket bulge.
I had the very same thing happen when I first started out with bokashi. No obvious signs of a failed bin, but the lid was bulging. We would suggest adding a generous handful or two of bokashi bran and mixing it as best you can into the food waste. Press the food waste down again and continue to fill as before. This extra boost of bokashi microbes may help to prevent further rotting and stop any more gases being produced (it worked for my bulging bin).
Let us know how you get on.
Happy composting 🙂

Hi Nicki.. Thank you for your detailed reply. I will start using more bran on each layer and let’s see how it goes. . .
