However, Carbonyx uses a proprietary, environmentally friendly process to produce what it calls Cokonyx, a synthesized replacement for traditional coke.
Burdette said bringing the company and this process to the state was an "incredibly significant recruitment."
"We're going to show the world how it's done," he said. "We're going to show them that you can use coal in an environmentally friendly way and change the economy of this country."
West Virginia Coal Association President Bill Raney called the new plant a "building block" that could demonstrate to the world that West Virginia can be a leader in effective and efficient use of natural resources.
"This is the maximum use of West Virginia coal," Raney said. "These new processes are going to demonstrate what we've been saying all along: West Virginians know how to do it."
Gaur said the company was attracted to the state not only because of its natural resources but also because of the leadership and attitude shown by its government from Tomblin down to local Jackson County officials.
"From Day 1 when I stepped into the state ... each and every one (of them) put every step forward in the best possible way to walk the extra mile to get this project to where it's at," he said.
"I'm glad to be here and what a wonderful new home you have given to our carbon alloy facility."
Early Thursday, the state Economic Development Authority approved a 10-year, $15 million low-interest loan package to Carbonyx to help the company finance the purchase of its initial round of equipment.
Burdette said this would likely be the only round of special financing for the company. He said the company would likely finance its later expansions on its own.
Carbonyx plans to break ground at the Millwood site next spring. Gaur said it should take 18 months to 2 years after the groundbreaking to have the plant fully up and running.
