Environmental ConservationEnvironmental objectives and performanceIn advancing its environmental activities, Tokai Carbon undertakes initiatives focused on the following four targets.(1) Legal complianceWe carefully confirm the requirements of relevant laws, ordinances, community treaties, and agreements and properly comply with them.In 2018, we had no business locations in violation of key regulatory limits or standards, and we had no cases of environmental lawsuits or penalties.(2) Zero environmental claimsEven when within standards outlined in relevant laws, ordinances, community treaties, and agreements, we appropriately respond to any incidents that could cause trouble for the local community.No significant environmental claims were made against Tokai Carbon in 2018.(3) Reducing CO2 emissions per unit productionTokai Carbon has established medium-term goals for its environmental activities.In 2018, each of our business divisions increased its production volume relative to the year earlier, and CO2 emissions rose as a result.In addition, CO2 emissions per unit production rose because maintenance at a carbon black plant required the temporary shutdown of in-house power generation facilities there and because of a relative increase in production of electrode products requiring comparatively high amounts of energy to produce.(4) Reduction of industrial wasteIn 2018, the volume of industrial waste generated rose compared to the prior year. This increase occurred because of higher production volume in response to strong demand, lower transfers of valuable waste, and efforts to upgrade/repair facilities and dispose of idle assets.By continuing to separate waste by type and pursuing value-added options in line with social conditions, we aim to further reduce the amounts of waste we send out for consigned treatment, or for final disposal in a landfill.Industrial waste generation and treatment (Consolidated, Japan)(t)Action2012(Base year)201620172018Vol. consigned3,8413,1043,2814,027 Portion of above sent to landfills1,7027771,0061,790CO2 Emission and Per Unit Production Data (Tokai Carbon Co., Ltd.)Units2012(Base year)201620172018CO2 emissionsThousand tons635 527 608 671 Graphite electrode businessThousand tons194 138 163 184 Carbon black businessThousand tons385 357 398 437 Fine carbon businessThousand tons54 31 44 47 Other businessesThousand tons2 2 3 3 Per unit production (vs. 2012)%100.0 96.1 100.5 101.9 Water Usage and Discharges of Environmentally Hazardous Substances into Water (Tokai Carbon Co., Ltd.)Units2016*12017*12018*1Water use1,000m³2,6122,6982,761BOD emissionskg2,3851,0621,461COD emissionskg10,1749,4736,944NOx emissionst571663672SOx emissionst6641,0311,162Total nitrogen*2t–4.75.4Total phosphorus*2t–0.20.2*1 Data-gathering period: April to March of the following year.*2 Reporting scope: Business locations that could impact the bodies of water specified in the Ministry of the Environment’s “Environmental Quality Standards for Water Pollution” attached table titled, “Environmental Quality Standards for Conservation of the Living Environment (Coastal waters, lakes).”36TOKAI CARBON ANNUAL REPORT 2018
