Marshall Isotopes Ltd. announced today, July, 2020, the successful completion of the transition from liquid fuel oil to natural gas (NG) as its energy resource. Natural gas is the cleanest of the fuels typically used for steam boilers, this transition is addressing global and local environmental issues by substantial reduction of the current CO2 emissions as well as particulate matter (soot), NOx and SO2. A special impact on the air quality is expected now at Marshall’s premises thanks to the significant reduction in the particulate matter (PM2.5) emissions. Therefore, the transition of Marshall to the NG era will lower the air pollution levels and improve the cleaner environment.
