American Resources (AREC) said Thursday it has expanded the first phase of its buildout of its refining campus in Marion, Indiana, to include four production lines.

The production lines will be capable of processing recycled and primary feedstocks, providing over 16,000 metric tons of annual separated and purified oxide capacity, the company said.

Initial production is expected in Q3 and the complete commissioning of phase 1 is anticipated throughout the year, American Resources said.
