US energy and environmental technology company Frontieras North America has appointed Robert Portz as vice president of operations and engineering, according to Yahoo Finance, as the company advances towards the commissioning of its first commercial facility using its patented FASForm Solid Carbon Fractionation process.

Portz, a Charleston, West Virginia native, becomes the first West Virginian to join Frontieras' leadership team and the company's first executive-level hire in the state where its flagship plant is under construction.

He brings extensive experience in refinery engineering and greenfield operations. Portz is best known in the industry for building Wyoming Renewable Diesel Company from the ground up under Sinclair's umbrella, a greenfield operation that generated more revenue in its first year of production than the adjacent refinery. He subsequently served as technical manager at PBF Energy's Toledo Refinery, where he oversaw process engineering, process design, capital projects, DCS operations and laboratory functions.

Portz's connection to Frontieras predates his appointment. He first met company CTO and co-founder Joe Witherspoon during their overlapping tenures at Sinclair Oil, where the pair worked together on refinery engineering projects over approximately six years. When Witherspoon later described the FASForm process to Portz in 2024, Portz became an early private investor in the company's first offering before accepting the operational role.

Frontieras North America is commercialising its FASForm Solid Carbon Fractionation process, a patented technology designed to fractionate solid carbon as part of an energy and environmental technology application. The appointment of a vice president of operations and engineering at this stage reflects the company's transition from development into commercial-scale delivery as construction of its flagship facility progresses.

The hire positions Portz at the centre of Frontieras' operational build-out, drawing on his track record of commissioning and scaling complex energy processing facilities in regulated and technically demanding environments across the US energy sector.
