Introduction: ZOMBIE FART MAKER Anaerobic Composter

About: Crazy about composting
I'm not responsible for any damage to anyone or anything caused while building and operating this device.
You might blow yourself into pieces if you don't take the special safety warnings serious [USE VERY NARROW METAL PIPES].
Make and use it at your own risk.


Rotting biomass put inside plastic bags causes a lot of problems:

• No control over the release of horrible smells.
• Leakage of stinky juice on the platform.
• Sometimes the bags just explode due to sheer pressure built inside by the gas.

I'm thinking about designing a anaerobic system which eliminates the said issues.

Step 1: The Benefits of Using ZFM for Composting

  • Produces compost faster than any aerobic system, since all the biomass is digested into a rotting pulp and degrades rapidly.
  • No digging/turning is needed at all, just leave it alone and come back later to claim your black gold.
  • Absolutely no gas/juice leakage
  • Cool geeky looks
  • Totally Environment friendly
  • Apartment friendly [You can even use it inside your bedroom]

Step 2: Build It

The basic idea is putting the biomass inside any plastic bottle (bigger = better), put a hole using a needle in the lid, and close the lid tight, then connect an air balloon as an air-lock to the lid, to collect any gas that is being produced.

Pictures will be added later

Step 3: Use It

  1. Simply put any biodegradable material you got into the tank, you can mince the larger ones for easier insertion and faster composting.
  2. Pour some water into the tank, at least enough to drown 1/4 of the materials
  3. Close the lid and put on the air balloon.
  4. Then just leave the ZFM alone and come back a week later.
  5. Once the balloon is totally bloated, it's time to get rid of the gas by one of these two methods:
    • Simply release all the gas at a well ventilated area.
    • Use the "EARTH CHILLER" system to turn methane of it into CO2 [Prevents global warming], EARTH CHILLER is nothing but a piece of very narrow metal pipe where one end is equipped with a tap.
      • You must connect the balloon to the open end of the pipe, place a flame in front of the tap, and open the tap, to burn all of the releasing gas. Be careful to not burn yourself or other stuff, the flame can be very violent and big depending on the balloon size and fullness.

Step 4: Variations

I guess it's better to divide the project into two variations, a lite, and a pro.
The lite version will be very easy and cheap to make, but more maintenance needing. The pro version is a bit harder and more expensive to make, but it reduces maintenance very well.


Lite version:

Just an air-balloon connected to a container, and you have to remove the balloon and get rid of the gases periodically (or else the balloon might explode).

Cons & Pros:

  • If the device is in your bedroom, it's easy to carry a balloon full of gases into the yard to release the gases.
  • cheap
  • easy construction
  • Suitable for indoors small scale composting
  • more work during maintenance


Pro version:

Any BIGGG container equipped with a balloon/barometer and also a metal valve on the lid. The other end of the valve must be connected to a very narrow metal pipe, to eliminate chances of explosion. The only maintenance is placing a flame in front of the valve, and open it.

Cons & Pros:

  • The gas can be fed to a compressor for storing into a can for using as fuel [got any ideas on how to do it?]
  • Awesome Steampunk looks [Especially if you paint it metallic copper or brass color]
  • Suitable for large scale outdoors composting
  • Less maintenance [Just watch the balloon/barometer to see if there's too much gas, open the valve, and please your inner pyromaniac kid >;)
  • Hard to move, and thus unsuitable/dangerous to maintain indoors, unless:
    • You accept the risk of burning the gases indoors, or use a long hose to transport the gases outdoors.
  • Harder construction
  • More expensive
