Processed solid burnable fuel composition
First Claim
1. A clean burning processed solid fuel composition providing an improved flame output for use in the manufacture of fire-logs, fire starters and fuel pellets, consisting essentially of:
- at least 50% by weight of dried spent coffee grounds;
at most 40% by weight of a normally solid combustible binder; and
the balance selected from at least one of a coking agent and a cellulosic material, the coking agent being at most 10% or less by weight of the total composition.

Abstract
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.
