Q

What is UBE's project planned for the Cornerstone Energy Park (CEP)?

UBE Corporation, a major manufacturer of chemicals in Japan, has been a global supplier for more than 120 years and has over 30 years of safe dimethyl carbonate (DMC) manufacturing experience. To enhance its presence in the U.S., UBE C1 Chemicals America Inc. (UCCA), a wholly owned subsidiary of UBE Corporation, is building a new manufacturing facility at the Cornerstone Energy Park (CEP) in Waggaman, Louisiana. UBE Corporation made its final investment decision for the UCCA project in February 2024, and the project received local permitting approvals in November 2024. This project will produce essential components for energy storage systems. This will be UBE's first large-scale facility in the U.S. and establish the first reliable domestic U.S. production and supply of these vital materials.

Q

What products will be manufactured by UCCA?

The UCCA facility will produce dimethyl carbonate (DMC) and ethyl methyl carbonate (EMC), both critical components used in energy storage systems that support products such as electric and hybrid vehicles, data centers and portable technology like phones and drones. Once constructed, the facility will produce the first reliable domestic U.S. supply for these vital materials. UBE's unique nitrite process was pioneered in the 1970s and allows for efficient production of DMC with reduced environmental impact and fewer by-products.

Q

What is dimethyl carbonate (DMC) and ethyl methyl carbonate (EMC)? How are they made?

Dimethyl carbonate, or DMC, is a colorless, low-toxic liquid that will be produced using UBE's proprietary process. This method dramatically minimizes by-products dramatically compared to conventional processes and reduces environmental impact. The chemical is a key ingredient in lithium-ion batteries, enhancing battery performance and lifespan by delaying the degradation of protective electrolytes.

Ethyl methyl carbonate, or EMC, is a solvent for electrolytes, which plays a significant role in how well lithium-ion batteries function overall. It is a clear liquid created by combining high-purity DMC with high-purity ethanol (a common type of alcohol). As part of the electrolyte solution, EMC improves battery performance, especially at low temperatures.

UBE's established manufacturing process ensures that both DMC and EMC are produced with high purity, which is crucial for the performance of energy systems.

Q

Why is this project needed?

UCCA will establish the first domestic U.S. supply of DMC and EMC. To date, most of these important materials in the energy storage supply chain have been imported from China. Establishing a domestic, stable supply chain is critical to ensure reliable access to materials essential for manufacturing energy storage systems that support products such as electric and hybrid vehicles, data centers and portable technology like phones and drones, and domestic chip manufacturing. As energy consumption in the U.S. increases, systems that store energy for later use will be key to meeting increasing demand. UCCA stands ready to help the U.S. meet that need with products made here at home.

Q

How would the manufacturing process and materials be handled for this project?

UCCA will oversee the construction and management of the Waggaman facility, upholding its commitment to safety and sustainability. UCCA will own the facilities and the produced materials and provide its specialized product expertise. Cornerstone Chemical Company will supply some feedstocks and utilities needed for the project.

Q

Will UCCA's new facility and its production process be safe?

UCCA's project is being planned and managed with the same rigorous commitment to safety and sustainability that is characteristic of all UBE facilities. The project is designed to increase site efficiencies and reduce by-products, resulting in cleaner processes and even safer operating practices.

Q

What are UCCA's safety and response plans for this project?

At UBE, safety and preparedness are our priorities. UCCA will utilize CEP's trained response personnel and site safety resources as part of this project. CEP has its own onsite fire station, emergency operating center, medical center, paramedics, and nursing team. Response personnel are trained and equipped to respond quickly to any emergencies that may arise onsite.

Q

Will UCCA's project impact the environment?

UCCA is committed to minimizing its environmental impact across all facilities it operates. UBE's proprietary nitrite process for producing DMC is highly efficient and generates fewer by-products compared to traditional methods, enabling the company to produce these critical components with a significantly limited environmental impact compared to other existing plants and processes in the industry.

Q

Would the production process or the completed facilities involved in the UCCA's facility be noisy, dusty or odorous?

UCCA designs its projects and facilities with careful consideration for the health and safety of its neighbors, workforce and the environment. This project will result in limited noise and odors, and will not produce dust.

Limited noise: UCCA will comply with any applicable noise regulations. Rotating equipment, such as compressors, create noise in a DMC/EMC plant. However, this commonly used equipment does not project noise beyond the site.

Limited odors: UBE's production design is compliant with all required regulations. Any potential for odor during the production process will be carefully monitored and mitigated.

No dust: DMC/ EMC products are in liquid form and shipped in ISO containers by truck. There is no dust produced during production or transportation. Some waste from production is solid. UCCA will treat solid waste using required and regulated processes so as not to impact areas outside of CEP.

Q

What is the estimated local economic impact (e.g., wages, salaries) of this project?

The UCCA project represents a significant $700 million investment in Jefferson Parish, which will boost industrial competitiveness and advance sustainability with minimal environmental impact while creating 50-60 new, full-time, skilled positions in the Waggaman community. This equates to an annual labor income surpassing $17 million. An analysis by GNO Inc. estimates that during the construction phase of the project, nearly 2,000 temporary jobs will be created generating an estimated $133 million in labor income with a $491 million capital expenditure.

Q

Will UCCA's project create new career opportunities in Jefferson Parish?

Yes, the UCCA facility represents a significant $700 million investment in Jefferson Parish, which will boost industrial competitiveness and advance sustainability with minimal environmental impact while creating 50-60 new, full-time, skilled positions in the Waggaman community. This investment will create valuable clean energy jobs and strengthen Louisiana's leadership in the chemical manufacturing supply chain, further developing southeast Louisiana's manufacturing workforce.
