Summarized Process of Building a Biogas Generator

digester process explainedMost of us like the idea of producing power free of charge and without polluting the environment at our home backyards. Today, thanks to “biogas to power” technology, this is possible for everyone. Not only is this technology being massively used in less developed countries like India, but it is becoming of great use to many people in the developed world a s well.

If you are one of those people who understand the importance of keeping your environment clean and free of pollution, then this kind of project might be perfect for you. Having passion for tinkering and building things yourself will help you as well. Maybe you have your own garage with plenty of tools, some free space in your backyard and you would like to lower your electricity bill? Starting your own biogas digester project can be great fun that pays for itself.

Making your own biogas digester, which is a part of the Liberty generator, is very simple, especially if you make a small sized one first just to test the method. Below are the simple steps you have to take to make your own small scale gas digester from stuff you can buy for peanuts. Cost efficiency is always important and if you have a way to test things before making them bigger and expensive, it is really a no brainer.

  • First you find a suitable container for the small scale digester. It can be an airproof box or a plastic barrel that was previously used for something else. The important thing is that it has no holes in it and won’t leak out or leak in air. Make sure the cover fits tightly and won’t leak as well.
  • The next step is to make a hole for the gas to go out of the digester, make with any electric tool or if you are using the plastic barrel you can also use a hot rod to make the hole. Position it on top as the gas will go up in the above container of gas.
  • The third step is to set up the biogas container, again it has to be airproof and put above the digester to catch all the gas. You can connect the two with a tube or some other similar equipment.
  • After that you can put in organic material in the digester for decomposition and seal it airtight. You have to create an anaerobic environment which means you can’t let any air in for the bacteria to work properly. Once the manure or other organic material is in, let it work for 10 to 15 days or so. If you open the digester in the meantime you will damage the environment bacteria needs for gas production.

This is a very simple concept you can try at home. The whole gas digester in Liberty generator is a bit more complicated to build, but also much easier to use once built. While you don’t need any special equipment for the test you will need some specialized gear you can get in any home depot stores in your neighborhood.

As said earlier, it is a good idea to make a small biogas digester at a much smaller scale to learn how to make it work properly for most efficient gas production. It takes some effort for a complete newbie to learn it, but once you do you have a great little asset you can use to save money and make the world cleaner in the process.

Here is a short video how to make a very small and simple biogas digester similar to Liberty generator, but with much smaller capacity and unstable environment.
