Bokashi Composting at Home: Bucket, Bran and Honest Limits
Bokashi composting is pickling, not rotting. You pack food scraps, including cooked food and small bits of meat that a normal compost pile cannot take, into a sealed bucket with an inoculated bran, and in about two weeks they ferment into a sour pre-compost. The catch most videos skip: that output is not finished compost, and it still has to be buried in soil or added to a pile for another few weeks.
Bokashi at a glance
- What it is: airtight fermentation of food waste using bran carrying helpful microbes (often sold as EM bran)
- Takes: cooked food, rice, roti, fruit and veg scraps, dairy, meat and small bones
- Avoid: soups, gravies and free liquid; mouldy food that is green or black
- Time in bucket: about 10 to 14 days after the bucket is full
- Then: bury in soil; wait about 2 weeks in warm soil, 3 to 4 weeks in cool soil, 4 weeks or more in pots
- Smell when healthy: sour, like achaar or vinegar, never rotten

What is bokashi, and how is it different from normal compost?
Ordinary composting is aerobic: microbes that need air break down greens and browns, and the pile must be turned. Bokashi is anaerobic: the bucket is kept sealed, and lactic acid microbes from the bran ferment the food, much the way cabbage becomes sauerkraut. Washington State University Extension describes the result as a fermented pre-compost that must be buried or finished in another compost system before it is ready.
| Question | Bokashi | Aerobic compost |
|---|---|---|
| Cooked food, meat, dairy? | Yes | Best kept out |
| Space needed | One bucket under the sink | A bin, matka or corner |
| Ongoing cost | Needs bran supply | Free |
| Finished product | Needs burying first | Ready to use when done |
| Dry leaves and paper? | Not useful | Essential browns |
If you already compost, read our guides to composting in a flat, bucket or matka and what not to put in a home compost. Bokashi fills the gap for the leftovers those systems should refuse.
What you need
- Two airtight buckets of about 15 to 20 litres, ideally with a tap at the bottom, or a homemade version: one bucket with holes drilled in the base sitting inside another to catch liquid.
- Bokashi bran (also called EM bran). Availability in Pakistan and India is patchy: it is mostly sold online by organic gardening sellers, so buy a few kilos at a time and store it sealed and dry.
- A potato masher or plate to press scraps down.
- A patch of garden soil, large pots, or an existing compost pile to finish the output.
How to start a bokashi bucket
- Sprinkle a handful of bran on the bottom of the bucket.
- Add the day’s food scraps, chopping large pieces such as melon rinds and bones into smaller bits.
- Scatter a handful of bran over each new layer. Use a little more for meat, fish and dairy.
- Press down firmly to squeeze out air. Air is the enemy of this process.
- Close the lid tightly. Open it only to add scraps.
- Drain the liquid every 2 to 3 days, or daily if the scraps are wet.
- When the bucket is full, leave it sealed for about 2 weeks at room temperature, ideally between roughly 18C and 29C, while you fill the second bucket.
Pre-drain your scraps
Tip leftover rice, daal and sabzi into a sieve for ten minutes before they go in the bucket. Wet scraps are the main reason bokashi turns putrid in Pakistani kitchens, where so much food is saucy. A layer of torn newspaper on top of the scraps, pressed down under the lid, also cuts air contact.
What can go in bokashi, and can it take meat?
Almost all food waste: vegetable peels, fruit scraps, cooked rice, roti, daal, cooked meat and chicken, fish, small bones, eggshells, cheese, yoghurt and tea leaves. Meat and dairy ferment safely in the sealed bucket. What does not belong: soups and gravies poured straight in, cooking oil in quantity, large bones, plastic, and anything already heavily mouldy.
Bokashi juice: what to do with the liquid
The liquid that drains out, often called bokashi tea, is acidic. WSU suggests diluting it and using it on soil, or pouring it down a drain. For plants, dilute it heavily, just a small splash in a full watering can, and pour it on the soil, never on leaves. Use it within a day or two; stored liquid goes sour and smells. Never use it neat on pots.
How to bury bokashi output
- Dig a trench or hole 8 to 12 inches deep in a bed you will not plant for a few weeks.
- Tip in the fermented scraps and mix them with at least 2 to 3 times their volume of soil.
- Cover completely with soil and firm it down so dogs, cats and crows cannot dig it up.
- Wait about 2 weeks in warm soil, 3 to 4 weeks in winter, before sowing or planting in that spot.
- Keep burial spots away from tree trunks and young roots, because the fresh output is acidic.
No garden? Fill a large tub one quarter with bokashi and three quarters with soil, cover, and leave it 3 to 6 weeks, then use it as rich soil for pots. Or add the output to a compost bin as a green ingredient. The food will still look almost fresh when it comes out of the bucket; that is normal.
Why does my bokashi smell bad?
A healthy bucket smells sour and pickled. A rotten, sulfur or ammonia smell means fermentation failed.
| Sign | Cause | Fix |
|---|---|---|
| Rotten egg or sewage smell | Too wet, too little bran, air leaks | Drain daily, add bran, check the lid seal |
| White fuzzy mould | Healthy fermentation | Nothing; it is a good sign |
| Green, blue or black mould | Air got in or too little bran | Bury that batch deep in a pile; restart with more bran |
| Flies around the bucket | Lid left open, scraps exposed | Seal properly; see our compost smell and fruit fly fixes |
When is ordinary compost the better choice?
Bokashi is a clever tool, not a must. Normal compost wins if you mainly have raw peels and dry leaves, if you dislike buying bran forever, or if you have no soil to bury into. It also handles garden waste such as fallen leaves and twigs, which bokashi does not use. Many gardeners do both: raw scraps and leaves to the compost pile, cooked leftovers to bokashi. More kitchen-to-garden ideas are in Kitchen Garden.
Never spread bokashi output on the surface or use it as mulch; buried scraps with meat attract dogs, rats and crows, and the fresh material can harm plant roots. Wash your hands after handling it, since it contains raw meat scraps. Do not plant edible greens in a burial spot before the waiting time is over. Keep buckets and liquid away from small children, and do not let stagnant water collect in lids or trays during the monsoon, when it can breed mosquitoes.
Bokashi questions people ask
How long does bokashi take?
About 10 to 14 days of sealed fermentation after the bucket is full, then roughly 2 to 4 weeks in soil before planting in that spot.
Can bokashi take cooked food and meat?
Yes. Cooked food, meat, fish, dairy and small bones all ferment well. Drain off gravy and soup first.
Is bokashi better than compost?
Neither is better overall. Bokashi takes cooked and animal scraps in a small sealed bucket; aerobic compost is free, handles leaves and gives a finished product.
Where can I buy bokashi bran in Pakistan or India?
It is mostly sold online by organic gardening suppliers. Check that it is sealed, dry and smells sweet and fermented, not musty.
Can I make bokashi without bran?
Not reliably. Without the inoculated bran, sealed scraps simply rot. Some people make their own bran with a microbe culture, but it still needs a starter.
How often should I drain bokashi juice?
Every 2 to 3 days in general, daily if the scraps are wet. Liquid left sitting turns the bucket sour and smelly.
Can I use bokashi in pots?
Yes, mixed with plenty of soil in a separate tub first, left for 3 to 6 weeks, then used as potting soil.
Does a bokashi bucket smell in the kitchen?
A sealed, healthy bucket smells only when opened, and then of pickles or vinegar. A rotten smell means it needs draining, more bran or a better seal.
