Toyo Glass: Japan's First* Large Glass Melting Furnace Using Oxy-Fuel Combustion Begins Full Operation
Toyo Glass has commenced full operation of Japan's first large glass melting furnace utilizing oxy-fuel combustion at its Chiba Plant. This innovative method eliminates the need for air, reducing greenhouse gas emissions per furnace by roughly 20% and eliminating large brick regenerators, thereby advancing low-carbon and resource-saving manufacturing.

Toyo Glass Co., Ltd. (Headquarters: Shinagawa-ku, Tokyo; President and Representative Director: Shingo Noguchi; hereinafter "Toyo Glass"), a consolidated subsidiary of Toyo Seikan Group Holdings, Ltd. (Headquarters: Shinagawa-ku, Tokyo; President and Representative Director: Takuji Nakamura), commenced operation of one large glass melting furnace for glass bottles utilizing an oxy-fuel combustion method on March 31, 2026, at the Toyo Glass Chiba Plant (Kashiwa City, Chiba Prefecture).
The oxy-fuel combustion method is a combustion process that uses high-concentration oxygen instead of air. By introducing this method, combustion without nitrogen becomes possible, improving the heat transfer efficiency to the glass. As a result, greenhouse gas (GHG) emissions per melting furnace are reduced by approximately 20% compared to conventional methods while maintaining standard production volumes.
Furthermore, the adoption of this method eliminates the need for a regenerator, which uses large amounts of heat storage bricks. The company promotes manufacturing with low environmental impact from both the aspects of "low carbonization" of the manufacturing process through energy efficiency optimization and "resource conservation" through equipment streamlining. Furthermore, Toyo Glass will pursue the reduction of environmental impact throughout the entire lifecycle of its products, delivering valuable containers that contribute to the decarbonized management of its customers.
*This is the first introduction of the oxy-fuel combustion method in a glass bottle melting furnace with a production capacity exceeding 200 tons/day in Japan (as of March 2026, according to Toyo Glass research).
Background of this Initiative
In the glass bottle industry, GHG emissions pose an industry-specific challenge because high-temperature combustion in melting furnaces requires a significant amount of energy. Toyo Glass has long been committed to promoting energy conservation and recycling, aiming to balance its business activities with global environmental preservation. The introduction of this oxy-fuel combustion method was launched in May 2024 as one of the most critical measures contributing to energy conservation and the realization of a decarbonized society. After a preparation and construction period of approximately two years, it has now commenced operation.
Future Outlook
This initiative serves as a model to drive the decarbonization of the glass bottle industry...
