Homemade sawdust press into fuel briquettes
There is no denying that sawdust briquettes are one of the most efficient types of solid fuel used for home heating. They are high in calories, have low ash content, and are also easy to store, since they take up little space. So these guys decided to figure out how to make expensive pressed briquettes themselves and at home.
They invented a device, they collected the necessary sawdust from the village and began to press it, preparing firewood for the winter.
