Bokashi composting is a fantastic method for breaking down food waste quickly and effectively—even items that traditional composting systems struggle with. But despite its flexibility, there are still clear dos and don’ts when it comes to what you should feed your Bokashi bin. Whether you're new to Bokashi or want to improve your composting results, knowing what can and can't go in is key to success.
What Can Go in a Bokashi Bin?
One of the biggest advantages of the Bokashi system is its ability to handle a wider range of food waste than traditional compost bins. Since Bokashi is an anaerobic (oxygen-free) fermentation process, it doesn’t rely on heat and airflow like standard composting.
Here’s what you can put in your Bokashi bin:
✅ Fruit and Vegetable Scraps
All peels, cores, and scraps from fruits and vegetables are welcome. Even citrus and onions—which are normally discouraged in traditional compost—can go in.
✅ Cooked and Raw Meat
Yes, Bokashi can handle both raw and cooked meat. Just make sure to chop it into smaller pieces and bury the fermented waste properly after processing.
✅ Dairy Products
Cheese, yogurt, and even small amounts of milk can be added to a Bokashi bin—something that’s a big no-no in traditional composting.
✅ Bread, Pasta, and Grains
All cooked or stale grains, including rice, pasta, and bread, break down well in Bokashi.
✅ Cooked Foods and Leftovers
Leftovers, including those with sauces, oil, or seasoning, are acceptable. Just be cautious of excess liquid and avoid soup-like waste.
✅ Eggshells
Crushed eggshells can go in, though they won’t fully break down—they’ll add calcium to your final compost.
✅ Coffee Grounds and Tea Bags
Coffee, tea bags (if not plastic), and filters are Bokashi-safe.
✅ Small Bones
Small chicken or fish bones will ferment and soften over time. Larger bones won’t fully break down and should be avoided.
What Not to Put in a Bokashi Bin
While Bokashi is flexible, it's not a free-for-all. Certain items can slow fermentation, attract pests, or interfere with the process.
❌ Liquids
Avoid adding soup, broth, milk, or other liquids. Too much moisture can lead to foul odors and disrupt the anaerobic process.
❌ Moldy or Rotten Food
While slightly spoiled food is okay, moldy or completely decomposed items may introduce the wrong microbes and create odor problems.
❌ Large Bones or Shells
Beef bones or shellfish shells are too tough to break down, even with Bokashi fermentation.
❌ Non-Food Items
Do not add plastics, paper towels, food wrappers, or biodegradable packaging—even if labeled "compostable."
❌ Excessive Oil or Fat
Small amounts from cooked food are fine, but pouring in used cooking oil or large amounts of greasy food can cause issues.
❌ Pet Waste
Bokashi is for food scraps only. Pet feces, litter, and bedding should not be added unless the system is specifically designed for it.
Final Thoughts
Bokashi composting is a game-changer for households looking to reduce food waste—including meat, dairy, and cooked foods. But like any system, it works best when you know what to put in and what to keep out. By sticking to the right inputs, you’ll produce nutrient-rich, pre-compost material that integrates beautifully into your soil.
