  • Process for making fuel cubes from straw
    Patent number: 5352252
    Abstract: A process for making fuel cubes from straw includes the steps of drying and cutting the straw, adding lime to the straw and applying ammonia to the straw. The straw is then placed in a densification machine or cuber where solid bricks are formed. The ammonia breaks down the natural crystalline lattice structure of the straw's cellulose thus allowing it to be compacted.
