The present invention relates to a solid burnable fuel composition which contains a major proportion of spent dried coffee grounds for forming into high density pellets, synthetic fire-logs and fire kindling products. A homogeneous mixture of at least 50% coffee, with 30% or less by weight of a combustible binder is compressed and extruded in the form of fire-logs. A pellet fuel comprising entirely coffee provides a higher energy fuel source than prior art fuel sources. Coffee has a higher calorific value than hardwood, providing an efficient fuel material requiring less combustible binder, such as wax, than prior art fire-logs, and offering a higher energy value pellet than wood without added binder.
