How to Convert a Gas Generator to Run on Trash

Converting a gas generator to run on biomass or other waste materials can be a great way to recycle trash that would otherwise end up in a landfill. It allows you to generate electricity or power equipment using free and renewable fuel sources. Here is a step-by-step guide on how to modify a gas generator to run on trash.

Gather the Necessary Materials and Tools

To convert your gas generator, you will need:

Construct the Gasifier Stove

The gasifier is where biomass like wood, sawdust, or other carbon-rich waste materials are heated with a restricted air supply to produce "syngas". There are many gasifier designs, but a simple one can be made from a metal drum.

Connect the Generator and Gasifier

You need to securely connect the two components to carry the syngas into the engine:

Modify the Generator

The generator needs some key modifications to be able to run on syngas instead of gasoline:

Prepare and Load Biomass Fuel

The gasifier requires carbon-rich biomass fuel like:

Fuel preparation:

Loading into the gasifier:

Generate Electricity!

You are now ready to startup your waste-to-energy generator:

  1. Start the air blower connected to the gasifier.
  2. Open the gate valve so syngas flows into the generator.
  3. Use the pull cord or battery to start the generator.
  4. Adjust the gas valve until the engine runs smoothly without shutting off.
  5. Congratulations! You are now generating power from waste biomass!

Running a generator from trash takes some DIY skills, but can be very rewarding. You can turn piles of unused waste materials into useful electricity or mechanical power completely off-grid!
