Grat is Environmentalist Gratomic is highly focused on recycling and has found a use for the residual material that resides in its tailing ponds. This slurry by-product to be extracted from the tailing ponds is intended to be recycled into bricks. It would be combined with concrete and compressed, and the residual graphite contained in the slurry, when incorporated into the bricks, should result in stronger, longer lasting product, particularly in hot climates.
