1. A method of forming a solid blast furnace fuel product which does not risk generation or release of a hazardous substance, comprising the steps of;

  • (a) creating a water lean well mixed mixture of coke breeze and/or coal fines and water to form free carboxy ions on the surface of the carbon particles;

    (b) dissolving styrene polymer resin in a hygroscopic solvent;

    (c) combining the dissolved styrene resin in the water and coke breeze and/or coal fines mixture and well mixing the combination, to react the surface with the mixture of hygroscopic solvent and styrene to form free carbon ions by exchange of the styrene polymer resin in the hygroscopic solvent for water;

    (d) emulsifying polyvinyl acetate in water, adding the emulsion to the combination of set (c) and well mixing the resultant to react the polyvinyl acetate with the styrene resin;

    (e) subdividing the resultant of step (d) into segments and applying pressure to each segment to create hard, non-degradable solid fuel objects.
