What is a Bokashi Bin


A Bokashi bin is a composting system that utilizes anaerobic fermentation to break down organic waste. It consists of a container, typically a bucket or bin, where food scraps and other organic materials can be placed for decomposition. The Bokashi bin process is a method of composting that is gaining popularity due to its efficiency, ease of use, and ability to handle a wide range of compostable materials.

How does it work

The Bokashi bin works by harnessing the power of beneficial microorganisms to ferment and break down organic waste. These microorganisms are often referred to as Effective Microorganisms (EM) and include bacteria and yeasts. When organic waste is added to the Bokashi bin, it is sprinkled with a specially formulated Bokashi bran that contains these microorganisms. The bran inoculates the waste and initiates the fermentation process.

Unlike traditional composting methods, Bokashi composting is an anaerobic process, which means it takes place in the absence of oxygen. The microorganisms in the Bokashi bran thrive in oxygen-deprived environments, converting the organic waste into a rich, nutrient-dense material known as Bokashi compost.

Benefits of using a Bokashi bin

There are several benefits to using a Bokashi bin for composting. Firstly, it allows for the composting of a wider variety of materials compared to traditional composting methods. Bokashi bins can handle not only fruit and vegetable scraps but also meat, dairy products, bread, grains, coffee grounds, and tea bags. This means that no organic waste needs to go to waste.

Secondly, Bokashi composting is a fast process. The fermentation in the Bokashi bin typically takes around two weeks, which is significantly quicker than traditional composting methods that can take several months. This makes Bokashi composting an ideal option for those with limited space or time.

Another major advantage of using a Bokashi bin is that it does not produce foul odors. Since the process takes place in a sealed container, there is no exposure to the air, which helps prevent the release of unpleasant smells associated with traditional compost piles. Additionally, Bokashi composting reduces the attraction of pests, such as flies and rodents, making it a more convenient and hygienic option for composting at home.

Furthermore, the resulting Bokashi compost is highly potent and nutrient-rich. It contains a high concentration of beneficial microorganisms, which can enhance soil fertility and promote healthy plant growth when added to garden beds or used as a top dressing.

Overall, using a Bokashi bin for composting offers a convenient, odor-free, and efficient way to convert organic waste into nutrient-rich compost for your plants and garden.

Composting Basics

What is composting

Composting is a natural process that involves decomposing organic materials into a nutrient-rich and soil-enriching substance called compost. It is a sustainable way to reduce waste and provide valuable nutrients for plants. Composting mimics the natural decomposition process that occurs in forests and other ecosystems, where organic matter is broken down by microorganisms and transformed into a beneficial soil amendment.

Traditional composting methods

Traditionally, composting occurs in large outdoor piles or bins, where organic waste is layered and allowed to decompose over time. These piles require regular turning to ensure proper aeration and decomposition. Traditional composting methods rely on the presence of oxygen and a balanced mix of carbon-rich (browns) and nitrogen-rich (greens) materials.

Composting at home

Composting at home has become increasingly popular as people strive to reduce their carbon footprint and maximize their use of organic waste. Home composting can be done using various methods, including traditional outdoor composting, vermiculture (composting with worms), and Bokashi composting.

Home composting allows individuals to divert food scraps, yard waste, and other organic materials from landfills, reducing methane gas emissions and producing a valuable resource for their gardens. It also promotes a connection with nature and a sense of environmental responsibility.

Understanding Bokashi Composting

What is Bokashi composting

Bokashi composting is a unique composting method that originated in Japan. The word “Bokashi” means “fermented organic matter” in Japanese. Unlike traditional composting, which relies on aerobic decomposition, Bokashi composting is an anaerobic fermentation process. This means that it takes place in the absence of oxygen, making it an ideal option for composting in small spaces or indoors.

How does Bokashi composting differ from traditional composting

The main difference between Bokashi composting and traditional composting lies in the decomposition process. Bokashi composting utilizes beneficial microorganisms to ferment organic waste, whereas traditional composting relies on aerobic bacteria to break down materials.

In Bokashi composting, the waste is fermented instead of decomposed. The fermentation process is achieved by inoculating the waste with Effective Microorganisms (EM) through the use of Bokashi bran. These microorganisms thrive in oxygen-deprived conditions, breaking down the organic matter and producing a nutrient-rich liquid and solid compost.

Traditional composting, on the other hand, involves the breakdown of organic material through aerobic decomposition, with the help of oxygen-dependent microorganisms. This process relies on regular turning and a balanced mix of carbon and nitrogen materials to provide the ideal conditions for decomposition.

Advantages of Bokashi composting over traditional composting

Bokashi composting offers several advantages over traditional composting methods. Firstly, Bokashi composting can handle a wider range of compostable materials, including meat, dairy products, and cooked food, which are typically not recommended for traditional composting piles. This means that a greater variety of waste can be diverted from landfills and turned into valuable compost.

Another advantage of Bokashi composting is its speed. The fermentation process in a Bokashi bin usually takes around two weeks, compared to several months for traditional composting. This faster turnaround time allows for a more efficient use of space and a quicker supply of nutrient-rich compost for your plants and gardens.

Furthermore, Bokashi composting is a suitable option for those living in apartments or small spaces where traditional composting may not be feasible. Since the process is anaerobic, it is odor-free and compact, making it a convenient and hygienic solution for composting in urban environments.

Moreover, Bokashi composting retains more nutrients in the final compost compared to traditional composting. The fermentation process preserves a higher percentage of nitrogen, phosphorus, and other essential elements, making the resulting Bokashi compost a potent soil amendment that can greatly enhance plant growth and soil fertility.

In summary, Bokashi composting offers a versatile, efficient, and odor-free alternative to traditional composting methods. It allows for the composting of a wider range of materials, provides faster results, and produces nutrient-rich compost that can significantly benefit your garden.

Ingredients for Bokashi Composting

Type of waste suitable for Bokashi composting

Bokashi composting can handle a wide variety of organic waste. This includes both kitchen scraps and other organic materials that are typically not suitable for traditional composting methods. The key is to ensure that the waste is properly prepared and managed within the Bokashi bin.

Food waste

Food waste is an excellent source of organic matter for Bokashi composting. This can include fruit and vegetable scraps, cooked food, meat, fish, poultry and bones, dairy products, bread, grains, coffee grounds, and tea bags. However, it is important to remember that large quantities of oily or greasy food waste should be avoided, as they can hinder the fermentation process.

To prepare food waste for Bokashi composting, it is recommended to chop or shred it into smaller pieces. This increases the surface area and promotes faster fermentation. It is also a good practice to drain excess liquids from food waste, as excessive moisture can affect the fermentation process within the Bokashi bin.

Other organic materials

In addition to food waste, other organic materials can be added to the Bokashi bin. This includes coffee filters, paper towels (without chemicals or synthetic fibers), small amounts of yard waste (such as leaves and grass clippings), and even pet waste (from herbivorous animals only). However, it is important to maintain a balance between carbon-rich (browns) and nitrogen-rich (greens) materials to ensure proper fermentation.

It is worth noting that the Bokashi bin is not suitable for composting large, woody materials or inorganic waste such as plastics, metals, and glass. These materials should be disposed of through appropriate recycling or waste management systems.

Preparing a Bokashi Bin

Choosing the right Bokashi bin

When preparing a Bokashi bin, it is important to choose the right container that suits your needs and space constraints. Bokashi bins come in various sizes and materials, including plastic buckets, bins with a spigot for liquid drainage, and commercial Bokashi composting systems. Consider the amount of organic waste you generate and the available space for composting when selecting a Bokashi bin.

It is crucial to ensure that the chosen bin has an airtight seal. This is because Bokashi composting is an anaerobic process that requires an oxygen-free environment for the fermentation to occur. An airtight bin prevents oxygen from entering and disrupting the fermentation process.

Setting up the bin

Once you have chosen a suitable Bokashi bin, it is time to set it up for composting. Start by placing a layer of Bokashi bran at the bottom of the bin. The Bokashi bran contains the Effective Microorganisms (EM) needed to kickstart the fermentation process. It is available in the form of dry bran or bran-infused pellets.

Spread a thin layer of organic waste over the Bokashi bran, ensuring that all the waste is covered with a thin layer of bran. Repeat this layering process as additional waste is added to the Bokashi bin. The key is to maintain a balance between waste and bran to ensure proper fermentation.

Pre-conditioning the bin

Before starting the composting process, it is recommended to pre-condition the Bokashi bin. This involves adding a small amount of Bokashi bran and water to the bin and sealing it for a few days. Pre-conditioning helps to activate the microorganisms in the bran and ensures a healthy fermentation process from the start.

To pre-condition the bin, add a handful of Bokashi bran to the bin and drizzle some water to dampen the bran. Seal the bin and let it sit for a few days, allowing the microorganisms to multiply and establish themselves within the bin. This step prepares the Bokashi bin for efficient composting.

Composting Process in a Bokashi Bin

Steps involved in Bokashi composting

The composting process in a Bokashi bin involves a series of steps that ensure the proper breakdown and fermentation of organic waste. These steps help to maximize the efficiency and effectiveness of Bokashi composting.

Adding waste to the bin

To begin the composting process, add your prepared organic waste to the Bokashi bin. Remember to chop or shred the waste into smaller pieces, and drain excess liquids if necessary. Layer the waste with a thin sprinkling of Bokashi bran, ensuring that all the waste is covered. A balanced layering of waste and bran promotes even fermentation and helps prevent odors.

Applying Bokashi bran

Each time you add waste to the Bokashi bin, it is essential to sprinkle a thin layer of Bokashi bran on top. This helps to evenly distribute the beneficial microorganisms, promoting fermentation and preventing the growth of harmful bacteria or molds.

Draining the liquid

As the organic waste breaks down and ferments, it releases a liquid known as Bokashi juice or tea. This liquid is nutrient-rich and can be collected through a spigot or by tilting the bin to drain excess liquid. Bokashi juice makes an excellent liquid fertilizer when diluted with water and can be used to promote healthy plant growth.

Fermentation process

Once the waste is added and the Bokashi bran is applied, the fermentation process begins. The beneficial microorganisms in the Bokashi bran work to break down the organic matter, converting it into a nutrient-rich compost. During this process, the sealed Bokashi bin should be kept at room temperature and away from direct sunlight.

Maturing the compost

After around two weeks of fermentation, the organic waste in the Bokashi bin will have transformed into Bokashi compost. The compost will have a pickled appearance and a slightly sweet and sour smell. At this point, the Bokashi compost needs to be further transformed through a maturing process.

To mature the compost, it is recommended to bury it in a garden bed or a compost pile. As the compost ages, it will continue to break down and integrate with the soil, enhancing its fertility and providing valuable nutrients to plants. The maturing process typically takes a few weeks to a few months, depending on environmental conditions.
