Abstract (en)
[origin: GB2545103A] Biofuel composition comprising waste coffee grounds (WCG). It is preferably solid, formed as briquettes, pucks or pellets, the pellets being suitable for combustion in a biomass boiler. Preferably it comprises at least 50% wt WCG, even more preferably at least 75%. At least half of this quantity is preferably made up of waste coffee grounds from the manufacture of instant coffee (IWCG). The biofuel may additionally contain a fibrous filler (sawdust, coffee bean husks), preferably less than 50% wt, and a binding agent (lignosulphonate, glycerol), preferably up to 10% wt. Other possible ingredients are oxidisers like sodium / potassium nitrate and processing agents like starch (also a binder). The biofuel preferably has a durability of at least 60% and a net calorific value of 16-24 MJ/kg. A method of producing such biofuel is also claimed, by compressing suitable feedstock into pellets etc. The WCG may be dried to a moisture content of 6-20%. Coffee oil is preferably extracted therefrom, then the WCG are mixed with other ingredients and the feedstock may be conditioned through treatment with steam, then pressed / extruded through a die having boreholes into pellets which are further cooled. A relevant apparatus is also claimed.
