Can I put shells, coffee grounds, egg shells, and large items into my bokashi bin?

Yes, you can add all of these items to your bokashi kitchen composter. We recommend chopping all food waste into 1-2″ pieces. Larger pieces are OK but may take longer to ferment.

Remember to be more generous with adding bokashi bran if you are adding shells and larger items to your bokashi kitchen composter.

The bokashi microbes thrive on the sugars and carbohydrates in our food waste. So, you can add coffee grounds to your bokashi compost but they should be mixed with a variety of other food waste including plenty of carbs and sugars (fruits and veggie scraps, cooked pasta etc).
