A renewable fuel, PKS is attracting attention worldwide from the perspective of carbon neutrality because it offers an effective way to help limit CO2 emissions. Indonesia is the world’s second-largest producer of palm oil. PKS, a palm oil mill residue, is available in large quantities.
The DIC Group made the decision to adopt PKS, despite the fact that is more costly than coal, the principal fuel currently used to fire the Karawang Plant’s boilers, because it is a solid fuel like coal with an essentially equivalent calorific value.
Since being acquired by PT. DIC Graphics as a subsidiary in 2012, the Karawang Plant has seen steady growth in production volume, which has driven up energy consumption. Curtailing the resulting sharp increase in CO2 emissions is thus a challenge facing the plant. In 2017, the plant introduced PKS on a trial basis and realized an annual decrease in CO2 emissions of approximately 5,000 metric tons by replacing around 12.0% of the coal used to fire its boilers with PKS.
Beginning in fiscal year 2018, the plant has increased the portion of coal replaced with PKS to 25.0% with the goal of boosting its annual reduction of CO2 emissions to 10,000 metric tons from the 2016 level and in doing so to contribute to a decrease in overall CO2 emissions by the DIC Group of approximately 2.0%.
The DIC Group has set a target for the reduction of its overall CO2 emissions of 7.0% from the fiscal year level by fiscal year 2020, an average annual decrease of 1.0%, in line with which it is taking steps to lower energy consumption and carbon footprint. To these ends, the Group has invested in the installation of biomass boilers, wind power facilities, solar power facilities and cogeneration systems, among others, with the goal of helping to combat global warming.
