I am looking to add a compost bin to my Bokashi system. As the Bokashi system is anaerobic, will the contents be safe to put in an aerated compost bin?

It is absolutely fine to add the contents of your Bokashi unit to a compost bin. The anaerobic process which takes place over the two weeks prepares the waste for either digging into the garden or adding to your compost bin. The two work well in parallel, enabling you to compost all your kitchen and garden waste together.
