ENTEK Lithium Separators, the only producer of “wet-process” lithium-ion battery separator materials owned and based in the United States, recently announced that Chicago-based BuiltWorlds member Clayco will serve as its design-build contractor for a new facility in Indiana. Clayco’s services will include design, engineering, procurement, construction, and concrete self-perform for the project.
ENTEK previously announced its plans in March to establish operations in Indiana, investing $1.5 billion in a new Terre Haute production facility. The project, which marks ENTEK’s largest investment thus far, will create up to 642 new family wage jobs by the end of 2027 and support the growing electric vehicle (EV) industry across the United States.
“We’re absolutely thrilled to confirm Clayco as our design build contractor on this momentous undertaking in Terre Haute,” said ENTEK CEO Larry Keith. “We’re embarking on a project that will have positive impacts on the local and larger economy, as well provide a key component required for the electrification of vehicles to further US climate goals — and a partner like Clayco brings the experience to make informed decisions to help us achieve our objectives.”
Clayco brings significant experience in the electric vehicle segment from projects with companies such as SK On and Group14 (which recently announced the world’s biggest factory for production of advanced silicon battery materials that is being designed and built by Clayco). Clayco has also delivered manufacturing plants throughout the entire electric vehicle supply chain, including battery component and mineral plants for anode and cathode providers, lithium-ion battery cell production plants, and vehicle manufacturing and assembly plants. With this experience, Clayco brings the focused perspective of plant and process requirements for projects like ENTEK’s new facility.
For ENTEK, Clayco will design and build the production facilities in Terre Haute, Indiana to house equipment for the production of lithium battery separators within approximately 1.4-million-square-feet of floor area. Clayco will provide multi-discipline design and engineering of the plant required to support ENTEK’s manufacturing process. In addition, Clayco will self-perform the concrete foundations, flatwork, tilt up wall panels, and concrete paving. At peak, construction is anticipated to reach approximately 400 workers. Clayco is in the initial stages of planning a series of community outreach events to begin to engage the local subcontracting community.
“We are very excited to work with ENTEK as well as the local community on this terrific project,” said Anthony Johnson, President of Clayco’s Industrial Business Unit. “Clayco is proud to be an industry leader in the design, engineering, and construction of manufacturing plants to support the growing US electric vehicle industry. We are incredibly honored to play such a significant role in ENTEK’s growth.”
BuiltWorlds’ Construction Tech Conference is intended to look holistically at how technology is influencing the way we build – from pre-construction through construction functions, in the office as well as in the field. Leading technology adopters, mature solution providers, and upcoming technology solutions gather each year to take the pulse of trends across the industry at the BuiltWorlds Construction Tech Conference.
