Under the basic environmental preservation policy of striving to reduce our environmental impact and curb global warming in harmony with the global environment, Osaka Soda actively works to make effective use of resources (cyclic use), which includes recycling and in-house reuse of waste.
Osaka Soda has set a target of reducing the final landfill rate to less than 1% by fiscal 2030. In fiscal 2023, the final landfill volume was 1,679 tons, and the final landfill rate declined 1.7 percentage points year on year to 4.6% as a result of promoting recycling.
Final landfill rate
Osaka Soda strives to recycle brine mud generated from electrolysis. Since fiscal 2023, we have expanded related initiatives to all factories, making it possible to recycle waste.
Osaka Soda reduces waste through its system that recovers hydrochloric acid and steam from hydrochloric acid production facilities and liquid waste combustion facilities, reusing these as resources and energy. These facilities use organochlorine compounds, by-products of our manufacturing processes. Osaka Soda is also engaged in the conversion of organic sludge generated from wastewater treatment into fertilizer, and the sorting, collection, and recycling of garbage.
