Bokashi Composting: The Method That Handles Meat, Dairy, and Cooked Food — No Pile Required
By Ku · Updated March 2026 · 8 min read
There's one question that comes up every time I talk about composting: "What about meat and dairy? Can those go in?"
The honest answer for regular composting is no — meat, fish, dairy, and cooked food create odor, attract pests, and can introduce pathogens into a backyard pile. I've recommended against them in every composting post on this site. But that answer changes completely with bokashi.
Bokashi is the one composting method that handles everything — including the foods that other methods can't touch. Meat scraps, fish bones, leftover pasta, cheese, yogurt, cooked vegetables. All of it goes in, all of it gets processed, and the whole thing happens in a sealed bucket on your kitchen counter with almost no odor and no pest risk.
According to a 2025 guide from the North Carolina Cooperative Extension, bokashi is "a simple, odor-free way to compost nearly all kitchen waste — including meat and dairy — right in your home." It's been used in Japan since the 1980s and is now gaining serious traction in American urban gardening communities.
Here's everything you need to know to get started.
Important distinction: Technically, bokashi is fermentation, not composting. The Arizona Department of Environmental Quality (ADEQ) clarifies that bokashi anaerobically ferments food rather than decomposing it. The result is a "pre-compost" that still needs to be buried in soil or added to a compost pile to fully break down. Think of bokashi as Stage 1, and burial or composting as Stage 2.
What Makes Bokashi Different From Every Other Method
| Factor | Regular Compost | Worm Bin | Bokashi |
|---|---|---|---|
| Meat & dairy | ❌ No | ❌ No | ✅ Yes |
| Cooked food | ❌ No | ⚠️ Limited | ✅ Yes |
| Space needed | Outdoor pile | 10-gal bin | Counter-top bucket |
| Time to finish | 2–6 months | 6–8 weeks | 2 weeks (+ burial) |
| Odor | Possible | Minimal | Slight pickle smell only |
| Ongoing cost | $0 | $0 | Bokashi bran ($10–$20/yr) |
The key trade-off is clear: bokashi handles what other methods can't, but it has an ongoing cost (bokashi bran) and a two-stage process. For households that generate significant meat and dairy waste, or anyone without outdoor space, those trade-offs are usually worth it.
How Bokashi Actually Works
The word "bokashi" is Japanese for "fermented organic matter." The system was developed by Dr. Teruo Higa at the University of the Ryukyus in Japan in the early 1980s, and it works through a fundamentally different mechanism than any other composting method.
While regular composting uses aerobic bacteria (which need oxygen) to decompose organic matter, bokashi uses anaerobic fermentation — the same biological process used to make kimchi, sauerkraut, and yogurt. The beneficial microbes involved include Lactobacillus (the same bacteria in yogurt), Saccharomyces (a yeast), and Rhodopseudomonas (a soil bacteria).
These microbes are delivered through bokashi bran — wheat or rice bran that has been inoculated with the microbial culture and dried. Each time you add food to your bucket, you sprinkle a handful of bran on top. The bran inoculant activates, ferments the food in an oxygen-free environment, and within two weeks produces a pickled pre-compost that's rich in beneficial bacteria and ready for the next stage.
The result smells slightly sour — like mild vinegar or pickles — which is a sign the fermentation is working correctly. It should not smell like rotting food. If it smells rotten rather than sour, something has gone wrong.
What You Need to Get Started
The bokashi bucket
You need an airtight container with a spigot at the bottom to drain off liquid. Two options:
- Commercial bokashi bin: Purpose-built with a false floor, tight-sealing lid, and drainage spigot. Costs $30–$60. Available at garden centers and online.
- DIY version: Two nested 5-gallon buckets (inner bucket has drainage holes, outer catches liquid) with a tight-fitting lid. The Arizona ADEQ specifically recommends this as a cost-effective alternative. Total cost: $5–$10.
Most households run two bokashi buckets simultaneously — one actively filling, one fermenting.
Bokashi bran
Available at garden centers, some hardware stores, and online. A standard bag costs $15–$25 and lasts an average household 3–6 months. Annual cost: roughly $30–$50.
Want to cut costs? The ADEQ guide notes that bokashi bran can be made at home using wheat or rice bran, water, effective microorganisms (EM), and molasses. DIY bran recipes are widely available online and bring the annual cost down significantly.
Step-by-Step: Running Your Bokashi Bucket
Sprinkle a thin layer of bokashi bran (about 1–2 tablespoons) on the bottom of the bucket before adding any food. This gives the microbes a head start on the first layer.
Add kitchen waste in 2–3 inch layers. Chop larger pieces into 2–3 inch chunks first — smaller pieces ferment faster and pack more efficiently. Include anything from your kitchen: fruit and vegetable scraps, meat, fish, cheese, cooked leftovers, bread, coffee grounds, eggshells.
After adding each layer of food, sprinkle a handful (roughly 1–2 tablespoons) of bokashi bran over the top. The NC Cooperative Extension recommends a handful of bran per 2–3 inches of food scraps as the standard ratio.
After each addition, press the food down firmly with a potato masher or your hand (using a glove). This removes air pockets and creates the anaerobic environment the microbes need. Seal the lid tightly after every use — air is the enemy of bokashi fermentation.
As food ferments, it releases liquid (bokashi tea) that collects at the bottom of the bucket. Drain it via the spigot every other day. This liquid is highly acidic and must be diluted before use — the ADEQ recommends a 1:100 ratio (1 part bokashi tea to 100 parts water) as a plant fertilizer. Use the diluted solution within 24 hours. Undiluted, it can be poured down drains to break up grease and prevent blockages.
Stop adding food when the bucket is full. Add a final generous layer of bran, seal the lid, and set it aside for a minimum of two weeks. During this time, start filling your second bucket. The fermentation continues undisturbed in the sealed environment.
After two weeks, the contents will look largely unchanged but will be thoroughly fermented — soft, slightly acidic-smelling, and teeming with beneficial microbes. This is your pre-compost. It cannot go directly on plants because of its high acidity. You have three options: bury it 8–12 inches deep in garden soil (away from existing plant roots), mix it into an outdoor compost pile, or mix it into a large tub of soil indoors. Within 2–4 weeks it fully breaks down and the soil is ready to use.
What You Can and Can't Put In
✅ Everything bokashi handles (that other methods won't)
- Raw and cooked meat, fish, and bones
- Dairy: cheese, yogurt, butter, milk
- Cooked leftovers of any kind
- Bread, pasta, rice (plain or sauced)
- All fruit and vegetable scraps
- Coffee grounds, tea leaves, eggshells
- Wilted flowers and small plant cuttings
❌ What bokashi can't handle
- Liquids — excess liquid disrupts the fermentation process
- Large bones — too dense for the microbes to penetrate effectively
- Paper and cardboard — better suited for regular composting
- Garden waste (soil, leaves, branches) — use regular compost for these
- Moldy or already-rotting food — introduces competing microbes that interfere with fermentation
Troubleshooting: What Went Wrong
The bucket smells rotten (not sour)
A sour or pickle-like smell is correct. A genuinely rotten smell means the fermentation has failed — usually because air got in, the lid wasn't sealed properly, or not enough bran was used. Empty the bucket, clean it thoroughly, and start fresh with more careful sealing and more bran.
White mold is growing on the food
White or light-colored mold is normal and good — it indicates the beneficial microbes are active. The University of Saskatchewan notes that white mold should appear within a few days of starting. Green, black, or fuzzy colored mold is a sign of contamination from competing organisms and means the bucket needs to be restarted.
No liquid is draining
Some foods produce very little liquid, especially if you're adding mostly dry or low-moisture scraps. This is fine. The absence of liquid doesn't mean fermentation isn't happening — check for the characteristic sour smell instead as your indicator.
The pre-compost isn't breaking down after burial
Pre-compost needs active soil microbes to complete decomposition. If it isn't breaking down, the soil may be too dry or too compacted. Water the area after burial and check that the pre-compost is buried at least 8 inches deep — decomposition microbes are most active in the upper soil layers where moisture and temperature are optimal.
How Bokashi Fits With Your Other Composting
Bokashi doesn't have to replace other composting methods — it can complement them. The ADEQ composting guide specifically recommends this combination: use bokashi to process meat, dairy, and cooked food (which can't go in other systems), then mix the finished pre-compost directly into your regular compost pile to accelerate it.
The high-acid bokashi pre-compost, when added to a compost pile or worm bin in small amounts, actually speeds up decomposition of the surrounding material. The beneficial Lactobacillus bacteria from the bokashi culture colonize the pile and increase overall microbial diversity.
Practically speaking, many households end up with a simple three-method setup: a regular outdoor compost pile for yard waste and clean kitchen scraps, a worm bin for fast processing of fruit and vegetable peels, and a bokashi bucket for everything else. Together, they handle virtually zero food waste going to the landfill.
Frequently Asked Questions
Can I use bokashi if I live in an apartment with no outdoor space?
Yes, with a workaround. The fermentation stage is entirely indoor. For Stage 2 (burial or composting), apartment dwellers have a few options: mix pre-compost into a large indoor tub of potting soil for 2–4 weeks before using on houseplants, share with a neighbor who has a garden, donate to a community garden, or check whether your city offers compost drop-off programs that accept pre-composted material.
Is the bokashi tea safe to use on edible plants?
Yes, when properly diluted. The ADEQ recommends a 1:100 dilution ratio for use as fertilizer. At that concentration, the beneficial bacteria are present without the acidity being harmful. Use it within 24 hours of diluting. Don't apply undiluted bokashi tea to plants — the pH is too low and can damage roots.
Does bokashi kill pathogens in meat and dairy?
Yes. The NC Cooperative Extension confirms that bokashi's high acidity kills off pathogens and weed seeds. The fermentation process creates an environment too acidic for most harmful microorganisms to survive. This is what makes bokashi safe for meat and dairy when other methods aren't — it's the same principle as pickling and fermentation in food preservation.
How long can I store a sealed bokashi bucket before burying?
The University of Saskatchewan extension notes that a finished bucket can be stored sealed for several months if needed. The fermentation stabilizes the material and the high acidity prevents putrefaction. This is useful if you finish a bucket in winter and can't bury it until spring — just seal it and leave it until conditions allow.
Is bokashi worth the cost compared to free composting methods?
Depends on your situation. If you generate significant meat and dairy waste that currently goes in the trash, bokashi is almost certainly worth it — you're converting landfill waste into usable fertilizer for $30–$50 per year. If your household generates mostly plant-based scraps, a worm bin or regular compost pile is more cost-effective. Many serious home composters use bokashi alongside those methods rather than instead of them.
The Bottom Line
Bokashi is the answer to the one question every composting guide eventually runs into: what do I do with the meat and dairy? It handles what other methods can't, fits on a kitchen counter, and produces both a liquid fertilizer (bokashi tea) and a soil amendment (pre-compost) in about two weeks.
The trade-off is real: unlike every other method covered on this site, bokashi has an ongoing cost. But for the average household that currently throws meat scraps and cheese rinds in the trash, $30–$50 per year to process all of that into garden-ready material is a reasonable exchange.
Have you tried bokashi? I'm especially curious whether anyone has used the DIY bran method — the economics of making your own inoculant are interesting and I've been meaning to test it. Drop a comment below.
