HEBER CITY, Utah (AP) -- Bill Hartlieb's welding shop smells like restaurant grease.
That's because Hartlieb has set up a small-scale refinery to recycle used vegetable oils from dining establishments into biodiesel fuel to power cars and trucks.
He's among a growing number of Utahns -- fed up with high gas prices -- who are using and making biodiesel and straight vegetable oil fuel, or SVO.
The practice is illegal under federal law.
Hartlieb, however, disputes the hobby violates the Clean Air Act. He says vegetable oil fuels release fewer emissions than petroleum.
