SHELTON, Conn. — Bic Consumer Products USA’s new FlameDisk offers consumers a convenient, portable alternative to charcoal. FlameDisk, which uses ethanol as its main fuel ingredient, heats up quickly and is cleaner than charcoal. The portable disk, which fits most charcoal grills, is ready to use in minutes after lighting and provides a steady flame for between 35 and 45 minutes — about the same rate as charcoal. With no ashes or soot to remove, cleanup is easy. Once FlameDisk is cool, the aluminum container can be thrown away. FlameDisk retails for $4.99 for one disk.
