Bokashijärjestelmä

Bokashijärjestelmä refers to a composting method originating from Japan. The core principle involves anaerobic fermentation of organic waste using a specific mixture of Bokashi bran, which contains beneficial microorganisms, primarily effective microorganisms (EM). This process is distinct from traditional aerobic composting.

The Bokashi system typically uses an airtight container. Food scraps, including meat and dairy, are layered with the Bokashi bran. The airtight environment prevents oxygen from entering, promoting a fermentation rather than decomposition process. During fermentation, the microorganisms in the bran break down the waste, producing a nutrient-rich liquid (Bokashi leachate) and a pre-composted material.

The Bokashi leachate can be diluted and used as a liquid fertilizer for plants. The fermented solid waste is not yet fully composted and requires further decomposition. It is often buried in the soil or added to a traditional compost pile, where it breaks down rapidly due to its pre-digested state. The Bokashi method is known for its ability to handle a wide range of organic materials, reduce odors, and produce a valuable liquid fertilizer. It is considered a sustainable waste management technique.
