Under the corporate philosophy of “Contribute to the healthy enhancement of daily living and industry based on our chemical technology,” Maruzen Petrochemical has committed substantial resources to its business activities with the aim of fulfilling its social responsibilities and enhancing corporate value ever since the establishment of the company in 1959. Moreover, Maruzen Petrochemical became a member of the Cosmo Energy Group in 2016, which enabled the company to maintain stable business operations to the present day with the support of all stakeholders.
Positioned as the ethylene center of a petrochemical complex, the primary role of Maruzen Petrochemical is to procure raw materials from petroleum refining companies and to provide a stable supply of products to the derivative companies as customers of the company. Maruzen Petrochemical intends to strengthen its collaboration with other members of the petrochemical complex to achieve the healthy development of the overall organization. Moreover, the company is making a sincere effort to expand its lineup of chemical products for the industrial and specialty chemical businesses with the objective of creating a new earnings pillar.
Furthermore, the company is implementing carbon-neutral measures throughout the entire supply chain, including trading partners, by further promoting technological development in the decarbonization field with the intention of realizing carbon net zero within the ethylene center and supplying carbon-dioxide-free technologies and chemical products in the future.
Because Maruzen Petrochemical handles large quantities of hazardous substances and high-pressure gases, safety is the highest priority. Recognizing the serious risks to safety and the environment, the company is maintaining zero-accident zero-disaster operations by protecting the health and safety of all employees and the local community in an effort to be the Number One Company for Safety.
The Maruzen Petrochemical Group will continue to evolve as it endeavors to be a company that is even more attractive and trusted by society and its stakeholders; the executives and employees of the Maruzen Petrochemical Group, therefore, humbly ask for your further understanding and support moving forward.

PRESIDENT, REPRESENTATIVE DIRECTOR Katsuyuki Funahashi
