Commercial charbroilers pollute more than trucks

Restaurateurs may be the next on the chopping block with air quality regulators after a new study revealed that  commercial charbroilers emit even more particulate matter into the air than diesel engines.

“Emissions from commercial charbroilers are a very significant uncontrolled source of particulate matter…more than twice the contribution by all of the heavy-duty diesel trucks,” said Bill Welch, principal development engineer for the study at UC Riverside’s Center for Environmental Research and Technology (CE-Cert).

“For comparison, an 18-wheeler diesel-engine truck would have to drive 143 miles on the freeway to put out the same mass of particles as a single charbroiled hamburger patty.”

A proposed control — a device that removes grease from the exhaust and traps it in water — will be tested  at the CE-CERT test laboratory . Researchers will evaluate the air stream released by the commercial charbroiler before and after they pass through the control device and measure how effective it is.

According to Welch, the testing involves “cooking a lot of hamburger patties,” but they don’t go to waste. After the emissions test, the hamburger patties are donated to a Redlands Regional food bank.
