Efforts for Environmental Protection
Harima Chemicals Group endeavors to accurately monitor environmental impacts imposed by business activities through material procurement, production, disposal and recycling.
Environmental Load Flow Chart
- COD: Chemical Oxygen Demand. The amount of oxygen necessary to chemically oxidize and stabilize contaminants in water. Higher values indicate more contamination.
- NOx: A nitrogen oxide in exhaust gas generated from boilers, incinerators, etc. NOx causes photochemical reactions by ultraviolet rays, producing photochemical oxidants.
- SOx: A sulfur oxide in exhaust gas generated from boilers, incinerators, etc. SOx is one cause of acid rain.
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
In fiscal 2016, the usage of biomass fuel increased due to the increase in the number of operation days of the biomass power-generating facility, but by changing the waste heat boiler's fuel from heavy oil to waste oil*1, the usage of fossil fuel decreased. 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.
- Waste oil: Refers to the waste materials generated with business activities such as lubricant oil, wash oil, solvent, etc.
NOx and SOx Emissions / COD Values
In fiscal 2016, NOx decreased due to the decrease in the boiler operation as compared with fiscal 2015, but there was no fluctuation of SOx. Regarding water discharge, both the drainage discharge and COD increased.
Energy Conservation by the Introduction of Energy "Visualization"
We are introducing the "visualization" of energy required for business activities, with monitoring devices being installed and expanded around our domestic bases, to conserve energy in production activities by extracting energy loss and optimizing manufacturing conditions. The "visualization" also enhances the environmental awareness of each employee, which brings on-site improvements.
Breakdown and Transition of the Amount of Waste
FY2016 Flow and Outcome of Waste
Calculation range: Harima Chemicals and Harima M.I.D.
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.

Efforts by Related Companies
Harimatec Czech, s.r.o.
In light of the adoption of EU*3 Packaging and Packaging Waste Directive,*4 each member country is preparing internal regulations to establish an agency to collect and recycle packaging and packing waste.
In compliance with Czech's Recycling Act, Harimatec Czech has signed a contract with a government-authorized recycling management company EKO-KOM for its system.
The Act requires a company that purchases packaging in which products are filled, and sells/distributes the products in the Czech Republic to cover the recycling costs of waste packaging. In order to promote the recovery of waste packing, it is necessary to join EKOKOM system and make a quarterly payment for the costs according to the quantity of waste packaging.
Harimatec Czech actively participates in activities that increase the recycling rate of waste packaging.
- 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.
- EU (European Union): Political and economic partnership based on the Treaty on European Union. EU promotes cooperation of 28 member countries in a wide range of areas including the Economic and Monetary Union, the Common Foreign and Security Policy, and the Police and Judicial Cooperation in Criminal Matters.
- Packaging and Packaging Waste Directive: 1994 EU Directive (94/62/EC) defines the recovery and recycling of waste containers and packaging. Its objective is to harmonize the policies on waste containers and packaging management individually implemented in each member country while increasing the level of environmental conservation by a setting recycling rate as a goal to be achieved.
