Household sealed cell alkaline and zinc carbon batteries may be recycled for use in steel making as follows. The batteries are pulverised then run through an acidic bath to neutralize the alkaline electrolyte. Next the materials are rinsed, then dried and mixed with granulated carbon steel typically in a ratio of 5 parts battery material to 95 parts granulated carbon steel. The mixture is compressed into briquettes for introduction into steel making furnaces.

Les piles alcalines et de zinc-carbone scellées d'usage domestique peuvent être recyclées pour être utilisées dans la fabrication de l'acier de la façon suivante. Les piles sont pulvérisées, puis disposées dans un bain d'acide pour neutraliser l'électrolyte alcalin. Ensuite, les matériaux sont rincés, puis séchés et mélangés à de l'acier ordinaire en grains typiquement selon un rapport de 5 parties de matériau de piles pour 95 parties d'acier ordinaire en grains. Le mélange est comprimé en briquettes pour alimenter les fours servant à la fabrication de l'acier.
