Kuraray Co Stock Price, News & Analysis

KURARAY CO UNSP/ADR (symbol: KURRY) represents American depositary receipts of Kuraray Co., Ltd., a company in the chemicals industry within the basic materials sector. According to public disclosures from its subsidiary, Calgon Carbon Corporation, Kuraray owns a business that manufactures and distributes activated carbon products used in purification and filtration applications around the world.

Calgon Carbon is described as a wholly owned subsidiary of Kuraray Co., Ltd. (TYO: 3405). Through this relationship, Kuraray is connected to activated carbon technologies that address demanding purification needs in areas such as drinking water, wastewater, pollution abatement, and industrial and commercial manufacturing processes. The subsidiary’s activities indicate that Kuraray’s portfolio includes materials and technologies that support water treatment and environmental management.

Business activities through Calgon Carbon

Calgon Carbon states that it manufactures and/or distributes activated carbon products derived from coal, wood, and coconut sources. These products are available in granular, powdered, pelletized, cloth, and sheet form. The company highlights that these materials are used in more than 700 distinct purification applications. This includes treatment of drinking water and wastewater, air and gas purification for pollution abatement, and various industrial and commercial processes that require contaminant removal.

The subsidiary also operates reactivation facilities where spent granular activated carbon (GAC) is thermally treated and returned to service. In published technical work, Calgon Carbon describes a proprietary custom municipal reactivation process used to treat PFAS-laden GAC from potable water treatment. The process is designed to remove PFAS compounds from the carbon and thermally destroy them, allowing the carbon to be reused while addressing concerns about these contaminants.

PFAS-focused water treatment capabilities

Calgon Carbon reports that its FILTRASORB branded granular activated carbon has been used for more than two decades in applications that remove PFAS compounds from drinking water, wastewater, and industrial streams. The company cites peer-reviewed studies and regulatory test methods showing that its reactivation processes can achieve high destruction removal efficiency for PFAS compounds and reduce them to non-detectable levels in the treated carbon and emissions under the test conditions described.

The subsidiary notes that GAC is widely recognized in regulatory discussions as a technology for PFAS treatment, and it positions its FILTRASORB products and reactivation services as tools for drinking water utilities and industrial users that need to comply with PFAS-related standards. These activities suggest that Kuraray, through Calgon Carbon, participates in segments of the chemicals and materials market focused on environmental remediation and water quality.

Global footprint via subsidiary operations

Calgon Carbon reports that it is headquartered in Pittsburgh, Pennsylvania, and that it operates manufacturing, reactivation, innovation, and equipment fabrication facilities in the United States, Asia, and Europe. In Europe, the company states that it operates under the Chemviron name. This global footprint indicates that Kuraray’s activated carbon business reaches multiple regions and serves customers in diverse regulatory and industrial environments.

The subsidiary also notes that it operates multiple reactivation plants in the United States and additional facilities in Europe and Asia, and that it manages what it describes as a large network of GAC reactivation facilities. These facilities support the recycling of spent activated carbon and the management of PFAS-laden carbon streams, which the company links to reduced landfill use and lower greenhouse gas emissions compared with continuous replacement with virgin activated carbon.

Relationship between Kuraray and Calgon Carbon

Calgon Carbon states that it was acquired by Kuraray Co., Ltd. in March 2018. It describes Kuraray as its parent company and notes that the combined organization offers complementary products and services in activated carbon and filtration media, equipment, and related services. Through this ownership, Kuraray is associated with purification solutions used in water treatment, air treatment, and industrial processing.

While detailed segment reporting for Kuraray is not provided in the available data, the information from Calgon Carbon indicates that a significant part of the group’s activity in basic materials includes specialty carbon materials and filtration media aimed at environmental and water quality challenges, including PFAS treatment and reactivation of spent carbon.
