What Is The Bokashi Composting System?

Learn how this ancient method is used as a sustainable solution.


More about Bokashi and what that means to us:

The Bokashi composting system is an old Japanese method that has been used for years. It is a composting system that does not utilize air (anaerobic). It is more of a fermenting process that happens. Unlike other composting methods, meat, dairy, and oils can be added to bokashi compost. Food scraps are added to a sealed container in layers, pressed down to release air, and a microbial based bran (Bokashi bran) is sprinkled on top of each layer. The bran assists in the food breaking down and fermenting.


Throughout the process, liquid from the food scraps is released by a valve. This liquid is referred to as “Bokashi Tea” or “Liquid Gold”. It is a concentrate that is diluted with water and used as a fertilizer for plants that adds intense nutrients and protects from disease. Once this process is complete, the fermented mixture can then be added to soil (either by burying it directly into the ground or adding it to bins filled with soil). After about 4 weeks, the soil would have completed the breaking down process of the fermented food scraps, which then produces a highly nutritious compost ready for planting.


With the recent rise in home gardening and composting, many people are now utilizing the bokashi method in their homes and urban areas with dense populations. It is perfect for small spaces and those without yards. Many urban areas are independently deploying micro-hauling services to residents and small bars and restaurants to help divert food waste, reduce carbon footprints, and regenerate food scraps to benefit urban gardens and the residents they serve.


Normally, there is no need for consumers to separate the inner pad from the outer packaging (which is certified ASTM D 6400 and landfill friendly). However, in an instance where one is bokashi composting, it would be necessary to separate the inner pad from the outer packaging before adding it to the compost. This would be the case for micro-haulers as well.


Grease Bags used for edible oils and animal fats benefit this compost in two ways: 1. Assisting in grabbing any oils added to the food scraps (keeping the bokashi tea oil free, which is better for the plants). 2. Introducing additional microbes to the compost which will assist in the breaking down of food scraps and add additional nutrients that help protect plants from disease.
