AMG Advanced Metallurgical Group NV said Oct. 16 that AMG Vanadium LLC completed the feasibility study to replicate its existing Cambridge, Ohio-based recycling facility, which will more than double its capacity to process spent catalysts.

Spent catalyst is a hazardous oil refinery and power plant waste, and the company recycles it into products including ferrovanadium, nickel and molybdenum.

The company's board approved the start of engineering work and is considering several possible locations near AMG Vanadium's existing plant.

Construction is expected to start in mid-2019 and finish in early 2021, resulting in over 35,000 tons of incremental spent catalyst processing capacity and over 6 million pounds of incremental vanadium production capacity. The announced expansion replaces the previously planned 30% expansion of the existing facility.
