Turn Your Poop Into Power -Methane Generator

Hi Friends Below are step by step instructions for a novice to build a system to produce methane from compost and store it in tanks for future use such as by converting a propane generator, available on the preplist, to run off your renewable methane. 

The generator will take a lot of prep work and testing, every model will be different so these general instructions should get you on the right path. 

I should also lead off by reminding everyone methane is a highly flammable gas and don’t do any of this in an enclosed space either. Safety is critical. 

Anyways here’s how to turn your poop into infinite renewable power…

"How to Build a Methane Production System from Compost"


Methane is a clean-burning, renewable energy source that can be produced through the anaerobic digestion of organic matter, such as food waste or animal manure. In this article, we will walk you through the steps to build your own methane production system from compost, starting from scratch.

Step 1: Gather the materials you will need

Before you begin, you will need to gather the following materials:

A container to hold the compost. This can be a simple plastic bin, or you can build a more elaborate system using barrels or tanks. The size of the container will depend on how much compost you plan to process at a time.

A gas collection system. This can be as simple as a plastic bag or balloon attached to the top of the container, or you can use a more sophisticated system with tubes and valves.

A gas storage tank. This can be a small cylinder or a larger tank, depending on your needs.

A burner or other device to use the methane. This could be a stove, furnace, or generator.

Step 2: Set up the container

The first step in building your methane production system is to set up the container for the compost. If you are using a plastic bin or similar container, you will need to drill a few holes in the top and sides to allow air to circulate. If you are using a more elaborate system with tanks or barrels, you will need to connect them using pipes or hoses.

Step 3: Add the compost

Once the container is set up, it's time to add the compost. You can use a variety of organic materials, such as food waste, yard waste, or animal manure. Mix the materials together well and make sure they are moist but not waterlogged.

Step 4: Set up the gas collection system

The next step is to set up the gas collection system. If you are using a simple system with a plastic bag or balloon, attach it to the top of the container using a rubber band or other fastener. If you are using a more sophisticated system with tubes and valves, follow the manufacturer's instructions to set it up.

Step 5: Wait for the methane to be produced

Now it's time to wait for the methane to be produced. This process can take anywhere from a few weeks to several months, depending on the size of the container and the type of compost you are using. As the methane is produced, it will be captured by the gas collection system and stored in the gas storage tank.

Step 6: Use the methane

Once you have collected enough methane, you can use it to fuel a burner or other device. Simply attach the gas storage tank to the device using the appropriate connectors, and turn it on. The methane will burn cleanly and efficiently, providing you with a renewable energy source.

Step 7: Prepare the generator

Before you can start using your methane to power the generator, you will need to prepare the generator itself. This may involve modifying the fuel lines or installing a new fuel regulator, depending on the specific model of generator you are using. Consult the manufacturer's instructions or a qualified mechanic to ensure that the generator is properly prepared for use with methane.

Step 8: Connect the methane storage tank to the generator

Once the generator is prepared, you can connect the methane storage tank to it using the appropriate connectors. Make sure all connections are secure and free of leaks.

Step 9: Adjust the fuel mixture

If your generator is designed to run on propane, you may need to adjust the fuel mixture to ensure that it runs properly on methane. Consult the manufacturer's instructions for guidance on the proper fuel mixture for your specific model.

Step 10: Start the generator and test it

Now you are ready to start the generator and test it using the methane you have produced. Follow the manufacturer's instructions for starting the generator, and listen for any unusual noises or other indications that it is not running properly. If you experience any problems, consult the manufacturer's instructions or a qualified mechanic for assistance.

Step 11: Monitor and maintain the generator

Once the generator is running smoothly, be sure to monitor it regularly and perform any necessary maintenance to keep it in good working order. This may involve cleaning the fuel lines, replacing the fuel filter, or other tasks as needed. By taking good care of your methane-powered generator, you can ensure that it runs reliably and efficiently for many years to come.


Building a methane production system from compost is a simple and rewarding project that can help you reduce your reliance on fossil fuels and contribute to a cleaner environment. With a little bit of effort and some basic materials, you can have your own methane production system up and running in no time.
