Bokashi and Composting Together
Thanks to a Compost Grant from Citizens Committee of New York, we were able to purchase and distribute 2 gallon buckets with lids to garden members. These are intended to facilitate at-home collection and transport of compostables to be added to our garden’s compost bins. These are small enough to fit in most bags, wheeled carts and bike panniers, and can potentially be simply carried by most people.
A full 2 gallon bucket probably weighs about 6-8 pounds. The advantage of using these buckets (and tight fitting lids) is to free up space in the freezer from compostables as well as facilitate handling & transport of drippy, potentially smelly food waste - which can be barriers to compost participation. A 2 gallon bucket can be brought to the kitchen counter when preparing food, and stored under the kitchen table when not in use. Once emptied in the bin, the bucket can then be used to carry finished compost home to amend the soil in tree pits, make seed starting mix, or plant a windowsill garden.
Most food waste bucket-toting garden members are simply filling them with vegan ‘green’ materials, including fruit and vegetable trimmings, tea and coffee grounds, spent cut flowers ect. However a few of us are using this buckets to collect and prepare food waste that cannot be directly added to an outdoor urban compost bin by using bokashi agent to ferment them. This includes grains (such as bread, pasta, rice), dairy (such as cheese, yogurt) and meat (such as uneaten cat food). In addition to keeping these materials out of the waste stream, the bokashi-fermented food waste serves as a compost accelerator; our piles steam through the winter registering 130-150 on the compost thermometer in the middle of the pile.
Start with spent bread, broken up as neccessary
Add dairy and meat scraps directly above the bread and grains wasted. We keep ours in the freezer separately awaiting the starting of a new bucket. If no more grains, meat and dairy is to be added - make note of the date - you’ll need to count 2-3 weeks from this date to determine when it can be put in the compost bin. cover with half a cup of bokashi agent.
If smell is a concern or problem, cover with a layer of coffee grounds. We keep these separate in a ceramic crock in our kitchen.
Continue to add vegan food waste in 2-4 inch layers, covering with bokashi agent after each addition. Unlike other composting systems, this is an anaerobic process, you actually don’t want air to properly ferment your food waste. Some cover with a paper plate or bag and push down on each layer.
When full, and 2-3 weeks after adding the meat/dairy/grains bring to your outdoor compost bin and dig it into what is already there. Cover with leaves, It can be a bit smelly. Note the white bloom on top, that means its been fermented properly.
