The three main components to make a DIY bokashi bucket are a bucket, a strainer, and a valve. When attaching the valve to the bucket, we just need to make sure there is no leakage. The rest of the process is super simple to do. It may not need electricity or heavy tools, should take approx. 20-30 minutes and costs less than $5 bucks.

Let's jump in on the fun and see some ideas to get started.

Main materials:

  • 5-gallon bucket / 18-20L paint bucket
  • Water valve
  • Strainer

Helper tools:

  • Knife
  • Marker

Step 1: Mark the size of the valve on the bucket


Using a pen or marker, trace around the water valve.

Step 2: From the marked circle, cut the opening hole for the valve


To cut the hole, you can use a knife and work it through. Depending on how thick your bucket is, this process may take longer or faster.

This step takes the longest amount of time in the process if you're doing it with a knife tool. To speed things up you may use a drill.

While cutting, scoop around the circle a few times to make sure the valve fits snugly. Get rid of the little pieces that fall out after you're done.

Step 3: Hook the valve onto the bucket


To make sure there is no leakage, you can wrap some Teflon tape around the neck of the valve. To be extra sure, you can fit another pipe to the opposite side of this valve. The two provide pressure on both sides to make sure it's water-tight.  And with this, you are basically done constructing the bokashi bucket. Told you this was super easy :)


As we are done creating our bokashi bucket, all we gotta do every day is:


And voila!

Updates on the bokashi bucket

We've been adding food scraps to the bucket–mainly fruits, veggies, egg shells. The smell is slightly sour. It gives me that kind of "ugh, um" re-action but it is not too bad. Looking inside the bucket, I see some beautiful white mold developing.


After adding in some grapefruit peels, I notice that that contents even smell nice and sweet. No houseflies have been buzzing near. No rats or other insects have been near the bin. Although I did spot a few ants here and there, they are insignificant in number. I'm very happy with the progress so far.

After making some homemade EM (effective microorganism), I tried it out in my bokashi bucket. You could make your own EM from the yogurt whey liquid. It contains millions of lactic acid bacteria. I mixed the EM with 10 parts water. In this bottle is the beneficial LAB.

Mix containing thousands of good microbes

With this, we can add a few mists of some good microbes into the bucket.


From what I've seen so far, there is no foul smell, no black mold and not too many ants around. There is some white mycellium growing.

If you're interested, I show you how to make your own EM in this post. Check it out later!

One week after lid shut closed

After the bucket is full, we shut the lid closed. This is what it looks like inside after one week in:

White mycellium developing in bokashi

It is beautiful, beautiful white fuzz developing. I am pleasantly surprised to catch this sight. Feels like white Christmas has come early to our house. And the smell seems like it's rushing out when we open the lid. Quite strong but it dissipates quickly.

Let's wait for another week. We may see some more magic happening.

I'll keep you guys updated as it's coming along.

Have fun DIY your bokashi

There are many other  ways to go about this. Hopefully, this post has sparked some ideas for you to get started with composting. I had fun making it with my dad. Enjoy & share your creations! We'll need to take this baby for a spin for the next few weeks. Until then, cheers and see you again here next time.
