KINGSPORT — BAE Systems announced Thursday it will pursue installing an “enclosed thermal treatment furnace” that could eliminate the need for “open burn” activities at the Holston Army Ammunition Plant. A joint Army-BAE Systems study weighed 25 different technologies to identify methods to safely decontaminate and dispose of site-specific waste. “It determined that mature technology known as a Car Bottom Furnace could treat a large portion of the explosives-contaminated materials and is the best option to reduce the environmental impact,” a news release from BAE, the plant’s operating contractor, noted. BAE pointed out the pursuit of the furnace technology is dependent on government funding.
