One of the challenges in achieving Japan's goal of "Net Zero Carbon by 2050" is to reduce CO2 emissions in the manufacturing processes of the materials industry. At present, fossil fuels such as natural gas and heavy oil are used in the melting process of raw materials for glass production so there is an urgent need to develop combustion methods using fuels with low environmental impact.
This project focuses on ammonia, which does not produce CO2 when burned, is already widely distributed as a fertilizer and industrial raw material, and has the same storability and transportability as propane. An ammonia-oxygen combustion burner will be installed in the architectural glass production facility at the AGC Yokohama Technical Center to conduct demonstration tests of ammonia combustion technology. In addition to evaluating the effects of ammonia combustion on glass and the materials that comprise the melting furnace, AGC and its partners will develop a burner that can meet environmental standards and aim to deploy it in glass melting furnaces on a full scale. In the future, the project will consider expanding the applications beyond glass to other materials manufacturing processes, such as steel and aluminum.
The AGC Group has designated the promotion of sustainable management as one of the priority issues in its AGC plus-2023 medium-term management plan and has set a target of net zero GHG emissions from its business activities in 2050. To date, AGC has implemented a variety of measures to reduce GHG emissions from the glass manufacturing process, including the introduction of an oxygen combustion system with high melting efficiency, fuel conversion from heavy oil to natural gas, and the introduction of electric boosters for melting. AGC will continue to contribute to the realization of a sustainable global environment through the supply of products and technologies that contribute to the reduction of GHG emissions, energy saving, and energy creation.
