Advanced Refining Concepts LLC said last week it started construction on the second phase of its refinery at Tahoe Reno Industrial Center.
The expansion will double production to 200,000 gallons a day of motor and industrial fuels, which the company produces from natural gas or biogases.
Separately, the Sparks-based company said its founders, Rudolf Gunnerman and Peter Gunnerman, have been issued a patent covering the basic components of the company's production process.
