The plant planned for Centralia, which has just received $US42 million ($A47 million) in project financing, has already marked the start of construction.
Following 12 months of work it should be completed sometime during the first quarter of 2015.
Once online, it is projected to have a process capacity of about 200 short tons per hour and employ about 25 individuals.
Coalview director David Schwedel said the company had worked diligently to bring the project through to fruition.
“We are grateful to the state of Washington for their cooperation and for the assistance of our entire working group,” he said.
Coalview Centralia was financed by Florida energy technology investor Schwedel along with Coalview Investment Partners.
It also received $26.5 million in environmental facilities revenue bonds from the Washington Economic Development Finance Authority.
“Centralia has a highly qualified mining, administrative and finance talent pool and we are looking forward to working with local constituents to move this process forward,” Coalview Recovery Group president David Henry said.
According to the company’s website, Coalview has been evaluating waste reserves and design systems for mining and reclamation sites since the early 1990s.
It specialises in the removal and processing of waste materials and is the only company with a sample extraction technique, an in-house laboratory, design and operating techniques.
