SF6-alternative gases control of emissions separating unit

EPA estimates that increasing our national recycling rate from its current level of 27 percent to 35 percent would reduce greenhouse gas emissions by 11.4 million metric tons of carbon equivalent (MTCE, the basic unit of measure for greenhouse gases) over landfilling the same material.
