Bokashi Composting

Introduction

Bokashi composting is an anaerobic fermentation process that uses beneficial microorganisms to break down all types of food waste, including meat and dairy. It’s an excellent method for urban dwellers and those who want to compost indoors without odors or pests.

What is Bokashi?

Bokashi is a Japanese term meaning “fermented organic matter.” The process uses a specific mix of microorganisms (typically including yeasts, photosynthetic bacteria, and lactic acid bacteria) to ferment food waste in an anaerobic environment. Unlike traditional composting, Bokashi is a pre-composting process that prepares waste for final decomposition.

Benefits of Bokashi

- No pests
- No odors
- Easy to manage
Nutrient Retention
- Preserves nutrients
- No leaching
- High-quality end product
- Rich in beneficial microbes

Getting Started

Equipment Needed
- Bokashi bin (airtight container)
- Bokashi bran (microbial inoculant)
- Food waste collection container
- Compost bin or garden space
Choosing a Bin
- Commercial Bokashi bin
- DIY airtight container
- Size: 5-gallon minimum
- Must have drainage
Bokashi Bran
- Commercial product
- DIY recipe
- Contains effective microorganisms
- Preserves waste

The Process

Collection
- Collect food waste
- Chop into small pieces
- Drain excess liquid
- Keep container sealed
Layering
- Add thin layer of waste
- Sprinkle Bokashi bran
- Press down to remove air
- Repeat until full
Fermentation
- Keep container sealed
- Drain liquid regularly
- Wait 2 weeks
- No turning needed

Maintenance

Liquid Management
- Drain every 2-3 days
- Dilute 1:100 for fertilizer
- Use as drain cleaner
- Don’t let accumulate
Temperature
- Room temperature ideal
- Avoid direct sunlight
- Keep away from heat
- Monitor for warmth
Odor Control
- Should smell sweet/tangy
- Bad smell indicates problems
- Add more bran if needed
- Check for air leaks

Troubleshooting

Bad Odors
- Too much liquid
- Not enough bran
- Air getting in
- Wrong materials
Mold
- White mold is normal
- Green/black mold is bad
- Add more bran
- Check container seal
Slow Fermentation
- Too cold
- Not enough bran
- Too dry
- Wrong materials
