Indoor Composting with Bokashi Bran: A Sustainable Solution for Limited Spaces

Scraping food waste off a board

Indoor composting has become increasingly popular, especially for those living in apartments or homes with limited outdoor space. One of the most effective and convenient methods for indoor composting is by using Bokashi Bran. 

What is Bokashi Bran Indoor Composting?

Bokashi Bran indoor composting is a specialized process that uses a mix of beneficial microorganisms to ferment kitchen scraps and organic waste in an airtight container. This process is odor-free, space-efficient, and suitable for small living spaces, making it an excellent choice for urban dwellers or anyone looking for a convenient way to recycle their organic waste.


Getting Started with Indoor Bokashi Bran Composting


Here are the steps to start indoor composting using Bokashi Bran:

  1. Select an Indoor Composting Bin: Choose a dedicated container for your indoor composting. Many Bokashi Bran kits come with a sealable bucket specifically designed for this purpose. Alternatively, you can use airtight containers or bins with a secure lid.

  2. Assemble Your Bokashi Bran Kit: If you purchase a Bokashi Bran starter kit, it will typically include Bokashi Bran, a bin, and a lid. Assemble the kit as per the provided instructions.

  3. Prepare Kitchen Scraps: Collect your kitchen scraps, including fruit and vegetable peelings, coffee grounds, eggshells, and small amounts of meat and dairy. It’s best to cut these scraps into smaller pieces, as this accelerates the fermentation process.

  4. Layering Process: Start by placing a layer of Bokashi Bran at the bottom of your indoor composting container. Add a layer of prepared kitchen scraps on top of the Bran, then sprinkle another layer of Bokashi Bran. Repeat this layering process until your container is full.

  5. Press Down and Seal: Press down the contents to minimize any airspace in the container, ensuring an anaerobic (no-oxygen) environment. This is essential for the fermentation process. Seal the container tightly with the lid to create an airtight seal.

  6. Fermentation: Place your sealed container in a cool, dark place, such as a kitchen cabinet. The fermentation process typically takes about two weeks. During this time, a slightly sour smell may develop, which is normal and indicates the process is working.

  7. Drain and Store Liquid: Throughout the fermentation period, liquid may accumulate in the container. Use a drain plate to remove and collect this nutrient-rich liquid, known as “Bokashi juice.” Dilute it with water and use it as a potent liquid fertilizer for your houseplants or garden.

  8. Composting Cycle: Once the Bokashi Bran has fermented your kitchen scraps, you can bury it in a garden or add it to an outdoor compost pile. This enriched soil will improve the fertility of your garden.
