Hokkaido Refinery | Environmental initiatives
This Refinery began operations in 1973 with the aim of becoming the "park factory of the northern land" based on our basic stance of "creating Refinery that is loved by local people," and has since provided a stable supply of oil to northern Japan. I have tried my best.
With the aim of harmonizing with the natural environment of Hokkaido, we have not only reduced the environmental impact on air and water quality, but also used low-benzene gasoline and sulfur-free (sulfur content of 10 ppm or less) gasoline. We have achieved results through initiatives such as creating products that do not place a burden on the environment and reducing waste, such as installing volatile hydrocarbon recovery equipment in lorry shipping facilities. We will continue our activities to make further improvements.
Employees working at our Refinery not only further raise their awareness of safety and the environment, but also recognize that each and every one of them is a global citizen, and work tirelessly to pass on Hokkaido's rich nature to the next generation. We will continue to accumulate.

Promotion of energy conservation
In order to use limited energy efficiently, our Refinery has implemented detailed energy management by introducing high-efficiency equipment and setting operational control values. We will continue to promote energy conservation with the aim of reducing unit energy consumption by more than 1% per year on average over the medium to long term.
Initiatives to reduce waste
Our Refinery established new zero-emissions activities in fiscal 2002, and has expanded our activities with the goal of achieving zero emissions in fiscal 2008. As a result, we achieved this goal in fiscal 2006, two years ahead of schedule. Currently, in order to further promote zero emissions, we have set a goal since fiscal 2015 to reduce the amount of final (landfill) disposal to less than 0.1% of the amount generated, and we have been achieving this goal every year.
*Definition of achieving zero emissions: The amount of final (landfill) disposal is less than 1% of the amount generated.
In addition, at our Refinery, we are considering improving waste from the perspective of "3R {Reduce, Reuse, Recycle}," and we have also formed a group of 11 neighboring companies. We are collaborating with other organizations such as the Tomakomai Zero Emission Network to gather information and proceed with our activities.

Environmental measures
Air pollution prevention measures
Flue gas desulfurization equipment that reduces SOx
At our Refinery, boilers and heating furnaces generate sulfur oxides (SOx), nitrogen oxides (NOx), and dust. To reduce the burden on the environment, we have installed flue gas desulfurization equipment for SOx and smoke denitrification equipment for NOx. Soot and dust are removed using electrostatic precipitators and filters. Through these reduction measures, we are complying with the pollution control agreement's exhaust gas standards, which are stricter than the Air Pollution Control Act.
Water pollution prevention measures
Our Refinery uses industrial water to cool products and semi-finished products. After use, we measure the hydrogen ion concentration (pH), chemical oxygen demand (COD), suspended solids (SS), and n-hexane extractables content of water after use, and comply with the effluent standards set by pollution control agreements. I am.
Soil pollution prevention measures
In 2003, the Soil Contamination Countermeasures Act came into effect, making it mandatory to conduct a soil contamination investigation when a designated facility that uses hazardous substances is closed down or when the governor recognizes that there is a risk of health damage.
Based on the Soil Contamination Countermeasures Act, Refinery conducts surveys to ascertain the status of soil contamination and investigate potential risks.
Initiatives to control chemical substance emissions
Volatile hydrocarbon recovery equipment
Among the chemical substances emitted from this Refinery, the substances subject to the PRTR Law (Act on the Promotion of Ascertainment of Emissions of Specified Chemical Substances into the Environment and Promotion of Management Improvement) include benzene and toluene contained in crude oil and naphtha. , xylene, etc.
To control chemical emissions, we use highly airtight floating roof tanks to store volatile substances, and we have installed volatile hydrocarbon recovery equipment in our lorry shipping facilities.

Factory green space and biodiversity
Refinery has been engaged in greening activities since the beginning of its operations under the harsh environment unique to Tomakomai, including sea breezes and volcanic ash.
In order to protect the trees planted on the premises from the sea breeze, we have installed net fences and created rocky mountains, and are now growing approximately 12,000 trees, including Japanese white birch, Japanese black pine, and other trees.
In addition, more than 100 double cherry blossom trees that are over 40 years old have been planted along the straight road on the south side of the premises, and are open to the public during the cherry blossom viewing season every year and are well received.

In August 2010, we received the "Social and Environmental Contribution Green Space Evaluation System'', which is a certification system for evaluating and certifying excellent greenery with a high level of contribution, operated by the Urban Greening Organization. It has been certified as a green space.
Since our operations began in 1973, we have been promoting environmental communication by creating green spaces at our plants, giving due consideration to biodiversity, and consciously working to coexist with wild birds and other plants and animals that live on our premises.
Corporate forest
Since December 1996, corporations and other corporations have taken advantage of the Forestry Agency's "Corporate Forests" system to participate in the maintenance of national forests and carry out social and environmental contribution activities. We manage the forest under the name "Appenai Water Forest". The contribution of this forest to the environment has been evaluated as absorbing 212.9 tons of carbon dioxide over 10 years.
In May 2008, we newly leased 4.5 ha of revenue-sharing afforestation in Tomakomai City.
This area was damaged by fallen trees in Typhoon No. 18 in 2004, and in June 2008, 102 elementary school students from the city were invited to participate in a tree-planting experience, and 6,500 trees of Scots spruce, white birch, and double cherry trees were planted. Did.
This forest has been named the "Idemitsu Green Natural Forest,'' which was chosen by elementary school students who participated in the tree-planting project, and will be maintained over the next 80 years.
According to the Forestry Agency evaluation method, the environmental contribution of the "Idemitsu Appenai Water Source Forest" and the "Idemitsu Green Natural Forest" in 2021 is 32.7 tons of carbon fixed and 3,957 cubic meters of water storage benefits in the basin.
In recognition of the above activities, in 2019, we received promotion to the certification label "Superlative Stage" (the highest stage) in the green certification system SEGES, which is implemented by the Urban Greening Organization, a public interest incorporated foundation. This Refinery is the first in Hokkaido to be certified.
