FIELD: chemistry.

SUBSTANCE: invention relates to a method of making fuel briquettes, which involves mixing carbon filler with ground coal, adding a binding substance and briquetting the mixture under pressure. The carbon filler, which is in form of aluminium wastes, anode paste and electrodes in amount of 25.1-85.00 wt %, is dry-mixed with ground brown coal until a 100% dry mass is obtained, followed by addition of the binding substance to the dry mass. The binding substance used is bitumen or polyvinyl alcohol in amount of 2-10 wt %, in excess of 100% of the dry mass. If polyvinyl alcohol is used as the binder, hydrophobic additives are added to the obtained mixture in amount of 1-5 wt %, in excess of 100% of the obtained mixture.

EFFECT: improved properties.
