The Fermentation Process
Bokashi composting is a unique and efficient method of organic waste management that relies on a fermentation process rather than traditional decomposition. This method, originating from Japan, utilizes a combination of anaerobic fermentation and the action of beneficial microorganisms to break down organic materials. The fermentation process begins when kitchen scraps are placed in a Bokashi bin, which is specifically designed to create an anaerobic environment. This environment is crucial as it prevents the growth of harmful bacteria and promotes the activity of beneficial microorganisms.
To start the process, organic waste should be layered in the Bokashi bin. Each layer of waste is sprinkled with Bokashi bran, which is rich in Effective Microorganisms (EM). These microorganisms include lactic acid bacteria, yeasts, and phototropic bacteria, all of which play a vital role in the fermentation process. The waste should be compacted to remove excess air, ensuring that the anaerobic conditions are maintained. It is essential to keep the bin tightly sealed to prevent oxygen from entering, as this can lead to unwanted odors and spoilage.
After the bin is filled, it should be left to ferment for about two weeks. During this time, the microorganisms will break down the waste, creating a nutrient-rich liquid known as Bokashi tea. This liquid can be drained from the bin and used as a powerful fertilizer for your garden. The remaining fermented waste can then be buried in soil, where it will continue to decompose and enrich the earth.
The importance of anaerobic conditions cannot be overstated in Bokashi composting.
