Things You'll Need
Sawdust briquettes are compressed blocks of sawdust that have been soaked and pressed at high pressure. These briquettes can then be used as fuel for heating or cooking. Compressed briquettes from sawdust, plant waste and waste paper are often used in undeveloped areas as a means of turning waste into cooking fuel. For the homeowner, these briquettes can provide a way to dispose of wood waste and cheaply heat the house.

Fill the bucket up about halfway with sawdust, fill the rest up with water. Allow the sawdust to soak for at least one hour, or until it begins to form a slurry.
Scoop the sawdust into the brick press and follow the instructions for pressing. Every press is different, but you will likely either need to push down on a lever or tamp the press down tight yourself.
Pull the compressed brick out of the press. Leave the brick out in the sunlight until it is completely dry. This will take different amounts of time based on your climate, but it could be several days. Place the bricks under an awning while drying if it begins to rain.
Try adding some paper to your sawdust when soaking to make a faster burning brick. Add wood ash to make the brick more sturdy.
