Ardagh Glass has successfully produced glass packaging using biofuel in a furnace during an industrial fuel switching trial at its Knottingley, UK facility. The trial resulted in a reduction of CO2 emissions by 242 metric tons compared to emissions from the same furnace operating entirely on natural gas.The £6 million (US$8 million) industrial fuel switching trial was funded by the UK Government’s Net Zero Innovation Portfolio program and led by Glass Futures, the UK-based Global Centre of Excellence for glass R&D, Innovation and Training.
