Iron Recycling - Cohen

recycling iron conserves energy and saves landfill space. It takes less energy to create iron and steel from recycled iron than from iron ore. Using recycled metals also helps mitigate some of the negative effects of the mining process, which is energy- and water-intensive and does lasting damage to the areas surrounding mines.
