SOx emissions during FY2020 increased by about 26% year on year. At THPAL, emissions rose by about 90% due to factors such as fuel properties and adjustments to operating conditions. NOx emissions increased by about 14% year on year. Soot and dust emissions decreased by about 15% year on year. At CBNC, emissions fell by about 58% due to factors such as the effects of fuel properties.
Each emissions figure was calculated based on the measurement of flue gas.
The COD*1 pollutant load in FY2020 decreased by about 11% year on year. The BOD*2 pollutant load increased about 15% year on year. Many SMM Group business sites face onto Japan's Seto Inland Sea and are subject to controls on the total amounts of COD, nitrogen and phos-phorous emissions under the Act on Special Measures Concerning Conservation of the Environment of the Seto Inland Sea.
The volume of freshwater usage decreased by about 5% year on year to about 35 million m3. In this calculation, diversion water,*3 which is unrelated to production, is excluded from withdrawal and release at mines. The volume of seawater usage increased by about 15% year on year. This was attributable to an increase in production volumes at the Toyo Smelter & Refinery.

An overview of releases and transfers of chemical substances based on Japan's Pollutant Release and Transfer Register (PRTR) system in FY2020 is as follows.
The number of data-submitting sites in the SMM Group was 23 (26 in FY2019). The Group had 40 substances requiring registration (42 in FY2019).
The total released and transferred amount (releases + transfers) came to 1,907 t, a decrease of about 14% year on year, mainly due to a decrease in manganese transferred outside of business sites resulting from a decrease in the volume of iron clinker¹ to undergo final disposal as industrial waste after being generated as a by-product at Shisaka Smelting Co., Ltd.
The amount discharged into the atmosphere decreased by about 44%. The main factor behind this was a decrease in releases of dichloromethane at the Ome District Division. In addition, there were no discharges of ozone-depleting substances. Dis-charges into water decreased by about 6% year on year.
The SMM Group has long been making efforts to reduce industrial waste in Japan and the amount of wastewater sludge (mining waste) that undergoes final disposal from the mine-affiliated Toyo Smelter & Refinery. The total final disposal amount in FY2020 was 51 kt, which was a decrease of about 20 kt from FY2019. The main factor behind this decrease was a decrease in the final disposal volume of iron clinker at Shisaka Smelting Co., Ltd.

The SMM Group has established two e-learning courses on environmental laws with the objective of raising levels of compliance. Employees, especially managers and supervisors involved with environmental laws and regulations and internal environmental auditors, are taking part in those courses. The e-learning course on Japan's main environmental laws covers ten laws that are deeply related to the businesses of the SMM Group and provides explanations of mandatory standards and notification procedures. As failing to comply with these requirements constitutes a violation of the law, employees must be certain to keep them in mind when conducting business. Given not only compliance with regulations and obligations, but also the voluntary risk management and information disclosure demanded of businesses today, the Group offers an e-learning course called Environmental Laws, Basic that serves as a stepping stone for properly conduct-ing business. This course covers 12 laws, including the Basic Environment Act and the Basic Act on Biodiversity.
