A few earth-saving green features of the Eco mug... - This porcelain mug is manufactured in energy-saving kilns powered by natural gas, one of the cleanest forms of energy available today. - 3% recycled porcelain is used in the clay formula in producing this mug, even though it increases the production cost of the product. - The manufacturing site for the Eco mug has established its own water recycling plant in an effort to further reduce its carbon footprint on the earth. - Residual heat from the kiln is directed to the drying line of the factory, maximizing the use of energy within the facility. - The Eco mug comes with a small tag printed on recycled paper featuring all of the above information, to minimize the unnecessary use of paper in packaging.
