Bokashi is a Japanese word for fermented organic matter. It is a different way of converting food waste/organic material into nutrient-rich soil amendment than the commonly known aerobic composting. Unlike compost, Bokashi is made by fermenting (acidifying) the food waste using micro-organisms under anaerobic conditions, i.e. in a completely leak-proof container.

For this to happen, you need the right aggregate of microorganisms: yeasts, lactic acid bacteria, and photosynthetic bacteria. These micro-organisms are also called EM which is the abbreviation for Effective Micro-organisms.

Understanding the Bokashi Process

The Bokashi process relies heavily on the use of a mixture known as Bokashi inoculant. This inoculant consists of either wheat bran or another similar substance that’s been inoculated with a specific group of beneficial microorganisms. When you add food scraps and organic waste into a Bokashi bin or Bokashi bucket, you’ll sprinkle a layer of Bokashi bran over it. This ensures that the food waste undergoes fermentation rather than decay.

What Can You Compost with Bokashi?

One of the most significant advantages of the Bokashi system is that you can compost meat and dairy products. These items are usually not recommended for a regular compost heap because they can attract pests. However, with the Bokashi method, these kitchen wastes become fermented material that can later be incorporated into garden soil.

DIY Bokashi

For households new to Bokashi composting, starting can be as simple as a DIY Bokashi project. All you’d need is a tight-lidded bucket, some inoculated bran, and your food scrap. Once the bucket is full, you seal it and let the anaerobic process take over.

From Bokashi Pre-Compost to Garden Gold

The Bokashi waste you produce is not usable compost just yet. It’s what’s often referred to as ‘Bokashi pre-compost’. This fermented Bokashi needs to be buried in compost trenches in a garden or added to a hot compost pile or worm bin to break down further. Once integrated into the soil, the fermented material becomes a rich, nutritious amendment that plant roots thrive on.

Bokashi Juice: A Bonus Byproduct

As the food waste ferments in the Bokashi composter, a liquid commonly termed “Bokashi juice” is produced. This compost tea can be diluted and used as a potent liquid fertilizer or as a natural drain cleaner.

Storing Bokashi Bran

It’s advisable to keep your Bokashi inoculant or Bokashi starter in a cool, dry place. For those looking for an upgraded version, there are options for premium Bokashi bran available in the market. If kept well, this inoculant can last for a long duration.

Why Choose Bokashi Composting?

Composting produces a myriad of benefits for the environment by reducing kitchen waste that would otherwise end up in landfills. The nature of Bokashi composting is particularly attractive due to its ability to handle meat products and its relatively quick turn-around time. Moreover, for those with limited space, the Bokashi system, requiring just a sealed bucket and a layer of bran, is an ideal choice.

Tips for Successful Bokashi Composting

  1. Ensure you press down each layer of food waste to remove any air pockets. Using a plastic bag or any other clean tool can help with this.
  2. Always ensure you sprinkle a layer of Bokashi bran after every layer of food scrap.
  3. Once your bin is full, ensure it’s sealed well to maintain an anaerobic environment.
  4. Regularly drain off the Bokashi juice from the bottom of the bucket to prevent the waste from getting too wet.
  5. Once you’ve completed a bucket, it’s helpful to have 2 bins on rotation. As one bin ferments, you can start filling the other with your kitchen scraps.

In conclusion, Bokashi composting offers a multi-step process that’s both efficient and environmentally beneficial. By leveraging the power of fermentation, households can convert their kitchen waste into a rich soil amendment that nourishes plants and benefits the garden ecosystem. Whether you’re a gardening novice or a seasoned pro, the world of Bokashi composting awaits!

Get started: Make Bokashi Compost in just 5 to 6 Weeks

It is very simple. All you need is:

  • fresh food waste
  • a Bokashi kitchen compost bin
  • composting yeast

Bokashi kitchen compost bin is specially designed for you to ferment all your food waste in it. It is no bigger than it can fit under the kitchen sink. It has a tight-fitting lid, drainage, and a tap. It holds 16 liters of food waste. The tight-fitting lid prevents odors and flies.

The bucket also comes with a small scoop for measuring the wheat bran inoculated with EM, a small cup for collecting the bokashi liquid, and a plunger for squeezing air pockets out of the food waste when you add it to the bucket.

Included with a Starter Kit are 2 Bokashi kitchen compost pails, a beaker, a plunger, a small shovel, and 1 kg of Bokashi slurry.

The Advantages of Making Bokashi in the Bokashi Kitchen Compost Bin

  • no odor nuisance in the form of rot
  • no bags
  • no insects or worms
  • emptied 1 to 2 times per month

You get your food waste converted into bokashi* in an oxygen-free fermentation process in the bucket – in a simple and ecological way. Bokashi is the name given to all organic material that ferments without oxygen with the help of bacteria and yeast-effective microorganisms. The food waste ferments and does not turn into the soil in the bucket – only when it gets into the ground does it turn into the compost/soil we know.

Compost in 5 to 6 Weeks

It takes only 5 to 6 weeks to make your own compost (bokashi) compared to the equivalent of 1 to 2 years for conventional composting. The whole composting process is fermentation. Every time you put food waste in the bucket, you add a bit of bokashi bran, which contains Effective Microorganisms. The microorganisms help to speed up the digestion of your food waste.

The micro-organisms make the food waste acidic instead of rotting. The pH slowly decreases to below 4. The acidity disappears after 14 days in the soil and at the same time, the pH adjusts to the soil’s own pH around 6-7.

In return, you get quality compost for your plants – plants in the living room, garden, and on the balcony. Another by-product is bokashi liquid, which is diluted 1:100/200 with water and is also a powerful fertilizer for your plants, conditioner for your drainage, or in the septic tank.

You get 3 useful products: solid fertilizer, liquid fertilizer, and drain cleaner.
