Chlorine plants in the U.S. pollute the air with hundreds of pounds of mercury each year, but a new report by the nonprofit Oceana finds that its would actually be cheaper for them to start using mercury-free methods. The report looked at 115 plants in the U.S. that are already using the cleaner technology, which is used in 90 percent of U.S. chlorine production, and found that conversion would pay for itself within five years by saving over $100 million in energy costs, while eliminating 4,400 pounds of mercury emissions from the five plants that still use the old technology.
