How Bokashi composting works

Bokashi composting is a two-stage process that combines anaerobic fermentation and aerobic composting. The first stage involves fermenting organic waste in an airtight container, known as a Bokashi bin, using a specialized Bokashi bran inoculated with effective microorganisms (EM).

1. The Bokashi bran:
   • Consists of a mixture of wheat bran, molasses, and a proprietary blend of microorganisms.
   • Acts as a starter culture, initiating the fermentation process.
   • Introduces beneficial bacteria, yeasts, and fungi to break down organic matter.
2. The fermentation process:
   • Organic waste, such as fruit and vegetable scraps, is layered in the Bokashi bin.
   • A sprinkle of Bokashi bran is added between each layer.
   • The airtight lid seals in the fermentation process, creating an anaerobic environment.
   • Over a period of 2-4 weeks, the effective microorganisms break down the waste through fermentation.
3. The end product:
   • The fermented waste, known as “Bokashi pre-compost,” is a partially decomposed, acidic material with a pickled aroma.
   • This pre-compost can be buried directly in the garden or added to a traditional compost pile for further aerobic decomposition.

The beauty of Bokashi composting lies in its ability to handle a wide range of organic materials, including cooked foods, meat, and dairy products, which are typically avoided in traditional composting due to potential odor issues and attracting pests.
