A solid burnable fuel composition which contains a major proportion of spent dried coffee grounds is described. The fuel composition includes at least 50% dried spent coffee grounds and a combustible wax which are mixed together and compressed into a suitable shape for combustion. The fuel composition may further include a small amount, 10% or less, of a coking agent useful to control burn rate and to prevent cracking of compressed fuel during combustion. Small amounts of cellulosic material may also be incorporated to improve the structural properties of the composition. Due to its superior heat and flame production, dried spent coffee grounds are an excellent fuel source for processed fuel products such as fire-logs and fuel pellets. The advantage is a hotter, cleaner burn which produces less soot and smoke, releases fewer harmful pollutants and provides a brighter flame over a longer period of time.

The biomass log fuel has not been commercialized due to difficulties in mass-producing the logs at low cost. The current invention solves this problem by introducing a three-step compaction process: pre-compaction, final compaction, and ejection. While a rotary feeder / compressor is used to perform pre-compaction, a ram driven by a toggle mechanism performs final compaction rapidly and efficiently. A press implementing the three-step compaction is designed and described. This invention should improve the cost-effectiveness of biomass solid fuel or feedstock.Biomass materials such as yard waste, corn stover and switchgrass are compacted at high pressure to form dense “biomass logs” without binder or heat. Biomass logs serve as a solid fuel for heating buildings, and as feedstock for bio-reactors for liquefaction or gasification. Densifying the uncompacted fluffy biomass reduces space needed for storage, decreases the number of vehicles needed to transport biomass, and increases the energy density of fuel.
