Efforts for Reducing Environmental Loads

Harima Chemicals Group endeavors to accurately monitor environmental impacts imposed by business activities through material procurement, production, disposal and recycling.

(Note) The aggregation method was revised in FY2011 regarding the methods for estimating the quantity of raw materials and the products.

Harima Chemicals Group, Ltd. is proactively tackling the reduction of substances of concern (SOC) generated during business activities. Furthermore, making an effort on the reduction of waste, promotion of recycling , and proper management are the activities aimed at the construction of a recycle-based society.

Reduction of Environmental Load Substances

Fuel Use

The consumption of fossil fuel increased in FY2015 compared to 2014 due to the increased use of kerosene for boilers other than the biomass power generation equipment.
As a result, CO2 emission increased. Fuel conversion to natural gas will be promoted, and thorough energy saving activities will be tackled for the continuous reduction of the substances of concern.

NOx and SOx Emissions / COD Values

Both NOX and SOX decreased in FY2015 compared to FY2014 due to the decreased operation of boilers.
Regarding the discharged water, the quantity was decreased but COD was unchanged. We will continuously carry out the monitoring of NOX , SOX and COD and will implement the reduction measures.

FY2014 Flow and Outcome of Waste

Zero Emissions*1

Zero Emissions Continued
In the past, the final landfill rate was shifting around 2% or higher.
Most of the waste sent to landfill was the incinerated ash from biomass fuels*2 since it contains a high ratio of Na and K. However, after many discussions and studies, we have been able to use the ash for producing cement since FY2005. We achieved the final disposal rate of 1% or lower in FY2006 and our zero emissions have been solid since.
In FY2010, recycling of our waste glass became possible, and as we continued reducing our waste, the amount of waste sent to landfill reached zero in FY2011.
We are committed to maintain our zero emissions for the future.
Transition of the amount of fuel use
Calculation range: Harima Chemical and Harima M.I.D.
Zero emissions: The concept proposed by the United Nations University that aims to formulate a new resource-circulating society by utilizing every waste product from one industry for a raw material in another and reduce every kind of waste to zero. Harima Chemicals strives for "reducing the landfill ratio of general and industrial waste generated from business establishments to 1% or less of the total amount".
Incinerated ash generated by a biomass boiler: The tall oil byproduct, which is the fuel for biomass boilers, contains acid decomposition of soap due to its manufacturing process. Since this byproduct contains a large amount of sodium sulfate (the ash content of approximately 1%), it used to be sent to landfill without being recycled for cement.
