Raw Materials

Ratio of Recycled Raw Materials (FY2022)

Ratio of recycled raw materials in incoming raw materials for the copper smelting business
14.9％

Ratio of copper from recycled raw materials in electrolytic copper
24.8％

Definition of Recycled Raw Materials

(1) Ratio of recycled raw materials in incoming raw materials for the copper smelting business)
(total dry volume of recycled raw materials processed at JX Metals Smelting Co., Ltd.*1) ÷ (total dry volume of primary and recycled raw materials processed at JX Metals Smelting Co., Ltd.) x 100 (Unit: %)

*1
However, the dry volume of recycled raw materials before pretreatment is calculated based on the pretreatment residue ratio if recycled raw materials are pretreated at JX Metals plants or affiliates, other than JX Metals Smelting Co., Ltd. and the dry volume of recycled raw materials before pretreatment is available.

(2) Ratio of copper from recycled raw materials in electrolytic copper
(amount of copper derived from recycled raw materials in copper anodes per year*2) ÷ (copper anode charge per year)

*2
Cumulative 12-month total of figures calculated monthly with (monthly copper anode charge in the electrorefining process at JX Metals Smelting Co., Ltd.) x (ratio of copper from recycled raw materials in copper anode*3).
*3
(Total amount of copper in recycled raw materials processed by JX Metals Smelting Co., Ltd. for the month) x (copper yield at Saganoseki Smelter & Refinery for the month) ÷ (total copper in net copper production at Saganoseki Smelter & Refinery for the month)
*4
In the electrorefining process, copper anodes are electrolyzed to produce electrolytic copper. Here, there is no input of copper components other than copper anodes. Therefore, the recycling ratio in copper anodes charged in the process is equal to the recycling ratio in electrolytic copper.

Energy

Energy Consumption
*
Energy consumption is calculated by applying the calorific value conversion coefficients for fuel and electricity as stipulated in the Act on Rationalizing Energy Use (currently, the Act on Rationalizing Energy Use and Shifting to Non-fossil Energy)
*
We revised calorific value conversion coefficients applied to electricity consumption, retroactively revising figures to fiscal 2020. (3.6 MJ/kWh is applied for electricity consumption).
Energy Consumption in Logistics Stages (Domestic)
*
Applicable to specified consigners as defined in the Act on Rationalizing Energy Use. Four Group companies fall under this definition: JX Metals Corporation, JX Metals Smelting Co., Ltd., Kasuga Mines Co., Ltd., and Pan Pacific Copper Co., Ltd.

Seawater usage at the Saganoseki Smelter & Refinery of JX Metals Smelting Co., Ltd. is calculated based on pumping capacity. Freshwater usage at the Saganoseki Smelter & Refinery of JX Metals Smelting Co., Ltd. and water usage at other operating sites are based on flowmeter readings or on invoices from the site’s respective water utility.
*2
The volume of water discharged into public waters (oceans and rivers) at each operating site represents the following: an amount calculated based on drainage weirs (Hitachi Works , Isohara Works, JX Metals Tomakomai Chemical Co., Ltd., and JX Metals Mikkaichi Recycle Co., Ltd.); an amount obtained by multiplying groundwater usage by a fixed rate (Kurami Works, Toho Titanium Co., Ltd.’s Chigasaki Plant); an amount from invoices (Toho Titanium Co., Ltd.’s Yahata Plant and Kurobe Plant); or an amount based on flowmeter readings (other operating sites). The volume of water discharged into the sewage system at each operating site represents the following: an amount calculated based on daily water discharge (TANIOBIS Co., Ltd.); or an amount based on flowmeter readings or on invoices from the site’s respective sewage utility for other operating sites.

Climate Change

CO2 Emissions From the Entire JX NMM Group (Scope 1 & 2)

This figure includes emissions from thermal energy (consuming steam, hot water, and cold water) supplied by third parties. The emission factors applied for Scope 2 calculation are as follows for domestic and overseas Group operating sites, respectively.
Domestic:
The latest adjusted emission factors per electric power utility published by the Ministry of the Environment and the Ministry of Economy, Trade and Industry are applied
Overseas:
Emission factors published by local power companies, national governments, or country-specific emission factors published in the IEA Emission Factors 2022, issued by the International Energy Agency (IEA), are applied

*1
Safety performance data is compiled on a calendar year basis (January to December).
*2
The number of casualties presented in this table includes work-related illnesses such as back pain and heat stroke.
*3
Each accident category is defined as follows.
  • Fatalities: Worker deaths resulting from work-related causes.
  • Occupational accidents with severe consequences: Accidents resulting in more than six months of lost work days or a disability grade.
  • Accidents with lost work days: Accidents requiring one or more days of absence from work for the purpose of examination, treatment or recuperation. These shall in principle be at a physician’s discretion. Note that this excludes “Occupational accidents with severe consequences.”
  • Accidents without lost work days: An accident that does not require one full day or more of absence from work as diagnosed by a physician, and in which the affected worker is able to go to work after the accident.
*4
Incidences related to the cause of the injury or illness, based on “Types of Accidents,” published by the Ministry of Health, Labour and Welfare.
*5
Both the frequency rate (the number of persons harmed or killed due to occupational accidents per million cumulative actual work hours) and the severity rate (number of work days lost per thousand cumulative actual work hours) cover Company employees and employees at other Group companies (including Toho Titanium).
*6
Safety statistics for subcontractor employees include not only those stationed permanently but also spot vendors. Note that these are subject to statistics for frequency rate and severity rate as of 2020. Cumulative work hours are calculated as follows: Number of permanently stationed subcontractor employees at the end of each month x number of operating days x 8 hours/day.
(Reference) In 2022, the frequency and severity rate of occupational accidents for all businesses in Japan were 2.06 and 0.09, respectively (Source: Ministry of Health, Labour and Welfare, “Survey on Industrial Accidents”)
*7
The Group defines a serious accident as one that results in four or more lost work days, and considers the occupational injury rate per 1,000 employees to be one of our key indicators for evaluation.
(Occupational injury rate per 1,000 employees (four or more lost workdays) = number of casualties with four or more lost workdays ÷ total number of employees (including employees of regular partner companies) x 1,000)
*8
No physical injuries were caused as a result of explosions/fires.
*9
While this includes Group companies and subcontractors, this data should be used only for reference as it is difficult to conduct follow-up surveys and aggregate working hours for subcontractors at overseas operating sites, and detailed data such as frequency rates are not disclosed.
