What is Bokashi Composting and How Does it work?

“Bokashi” is a Japanese word that refers to “fermented organic matter.” Bokashi composting is a technique that transforms food waste and organic waste into nutrient-rich soil butter for your plants. The liquid called bokashi tea makes an excellent fertilizer that can be used for feeding plants. This process, also known as anaerobic composting, harnesses fermentation to create nourishing soil amendments. This method of traditional composting is significantly faster and has the added benefit of being completely odorless. It’s a perfect solution for indoor composting in your home or apartment, ensuring a pleasant environment while effectively turning waste into nutrient-rich compost.

How does the bokashi system work?

Bokashi composting entails layering your kitchen waste with a unique bran containing beneficial, effective microorganisms within a sealed container (bokashi bin). This method creates an oxygen-free environment, allowing anaerobic bacteria micro organisms to swiftly and effectively decompose food scraps. As a result, the composting process becomes more efficient. Furthermore, Bokashi composting presents a convenient and odour-free solution for individuals seeking to compost in their homes or apartments.

Food waste for Bokashi compost bin

What food waste can you expect to ferment in your bokashi bucket?

Bokashi composting is extremely versatile and can easily handle a wide variety of kitchen waste. You can typically ferment the following types of kitchen scraps and organic matter in a Bokashi system:

  1. Fruit and Vegetable Scraps: Peels, cores, seeds, and other fruit and vegetable scraps are suitable for Bokashi composting.
  2. Coffee Grounds and Tea Bags: Used coffee grounds and tea bags, including the paper part, can be added.
  3. Eggshells: Crushed eggshells provide valuable calcium and can be included in the Bokashi system.
  4. Dairy Products: Small amounts of dairy, such as cheese, yogurt, and butter, can be added.
  5. Meat and Fish: Bokashi composting allows for the fermentation of meat and fish scraps, including bones. However, these should be in smaller, manageable pieces.
  6. Bread and Grains: Stale bread, leftover pasta, and other grains can go into the Bokashi bin.
  7. Small Quantities of Cooked Food: While not all cooked food is suitable for Bokashi composting, small amounts can be added. Avoid large quantities of oily or heavily seasoned dishes.
  8. Fats and Oils: Small amounts of fats and oils are generally accepted, but avoid excessive amounts.

Items that are not typically recommended for Bokashi composting include large bones, large quantities of liquid, and highly acidic or salty foods.

The key to successful Bokashi composting is to cut or chop the waste into smaller pieces, which facilitates the fermentation process. Your kichen waste pile should also be layered in the Bokashi bin, and each layer should be coated with the special Bokashi bran containing beneficial microorganisms.

Bokashi composting has numerous advantages compared your traditional pile


Bokashi composting is an incredibly versatile method of kitchen waste disposal. It can effectively handle a wide variety of organic materials, including meat, dairy, and cooked foods. This makes it a highly adaptable and efficient solution for managing and recycling kitchen waste.

Speed of Decomposition

The anaerobic fermentation process in Bokashi composting accelerates the breakdown of organic matter, producing compost faster than some traditional composting methods.

Indoor Composting

Unlike traditional compost, composting with a bokashi bucket can be done indoors, making it suitable for those with limited outdoor space or living in urban environments. The airtight containers used in the process help control odors.

Minimal Odor

Unlike certain conventional composting methods that rely on an aerobic process, Bokashi composting is an anaerobic process that generates minimal and gentle odors thanks to its airtight container that facilitates the fermentation process.

Nutrient-Rich Compost

The end product of Bokashi composting is a nutrient-rich compost butter that can be buried in the compost trenches of your garden. The fermented material preserves the nutrients in the organic matter.

Bokashi Tea: Liquid Fertilizer

Bokashi composting generates a nutrient-rich liquid byproduct known as “Bokashi tea.” This liquid, also known as black gold, can be collected and used as a liquid fertilizer for feeding plants.

Space Efficiency

Bokashi bins are compact, and the bins can be easily managed in small spaces, making them suitable for apartment dwellers or those with limited gardening space.

Reduction of Methane Emissions

By diverting organic waste from landfills, Bokashi composting helps reduce methane emissions, a potent greenhouse gas produced during the decomposition of organic matter in anaerobic conditions.

Enhanced Soil Structure

Adding Bokashi compost to your garden soil improves its structure, water retention, and aeration. It also introduces beneficial microorganisms that contribute to the overall health of your soil

Easy to Manage

The Bokashi composting method is a straightforward process that requires minimal effort and doesn’t involve the frequent turning or monitoring of compost piles associated with some traditional composting methods.

Top Tip

If you own a worm farm, feed your bokashi compost to your worms; they absolutely love them, and they will create compost and liquid feed far faster than traditionally fed worms.

Choosing the Right Bokashi Bin

When it comes to reducing household food waste, a Bokashi bin is a great solution. But with so many options on the market, it can be tough to know which one is right for you. The first thing to consider is size. Do you have a big family whose food scraps need to be accommodated? If so, a larger bin would be ideal. Another thing to look for is a tight-fitting lid. This will help to keep any odors contained. It’s also important to choose a bin with a strainer at the bottom. This will allow any liquid to drain out, preventing unpleasant smells and mold growth. By taking all of these factors into consideration, you’re sure to choose the perfect Bokashi bin for your household’s needs.

  5. Seal the Bin: Once you’ve added a layer of food waste and Bokashi bran, seal the bin tightly. This helps to create an anaerobic environment, which is necessary for the composting process.
  6. Let it sit. Allow the bin to sit in direct sunlight for two weeks. During this time, you can continue to add new layers of food waste and Bokashi bran as needed
  7. Compost is Ready: After two weeks, your compost should be ready. It will have a sweet and sour smell, similar to pickles.

Tips for Troubleshooting Common Problems with Bokashi Composting

Unpleasant Odor

  • Problem: A foul odor is coming from the Bokashi bin.
  • Solution: Ensure that the container is properly sealed after each use. Check the drainage system if your bin has one. If odors persist, add more Bokashi-inoculated bran to neutralize smells and maintain a balanced carbon-to-nitrogen ratio.

Mold Growth

  • Problem: Mold appears on the surface of the Bokashi waste.
  • Solution: Mold can develop if the waste is exposed to air. Make sure to press down the waste layers firmly to expel air, and add more Bokashi bran to reduce moisture levels.

Excessive Liquid

  • Problem: Too much liquid is accumulating in the Bokashi bin.
  • Solution: If there’s excess liquid, it may indicate too much moisture. Add more absorbent material, like shredded newspaper or cardboard, to balance moisture levels. Ensure proper drainage if your bin has this feature.

Incomplete Fermentation

  • Problem: The waste doesn’t seem to be fermenting properly.
  • Solution: Check the Bokashi bran expiration date; it may have lost its effectiveness. Ensure that the waste is cut into small pieces and that each layer is thoroughly coated with Bokashi bran. Maintain an airtight seal to create the anaerobic conditions needed for fermentation.

Pest Issues

  • Problem: Insects or pests are attracted to the Bokashi bin.
  • Solution: Make sure the bin is sealed tightly to prevent pests. If you’re burying the fermented waste, bury it deep enough to discourage pests. Avoid adding large amounts of meat, dairy, or oily foods, as these can attract unwanted pests.

Slow Fermentation

  • Problem: The fermentation process seems slower than expected.
  • Solution: Ensure that the waste is adequately covered with Bokashi bran, and maintain the airtight seal. Warmer temperatures generally speed up fermentation, so placing the bin in a warmer location may help.

Remember that Bokashi composting is a dynamic process, and you may need to make adjustments based on the specific conditions and organic materials used. Regular monitoring and adjustments can help troubleshoot issues and ensure successful Bokashi composting.
