The Environmental Protection Agency has its eyes on pollution
from backyard barbecues.
The agency announced that it is funding a University of California project
to limit emissions resulting in grease drippings with a special tray to
catch them and a “catalytic” filtration system.
The $15,000 project has the “potential for global application,”
said the school.
The school said that the technology they will study with
the EPA grant is intended to reduce air pollution and cut the health hazards
to BBQ “pit masters” from propane-fueled cookers.
Charged with keeping America’s air, water and soil clean,
the EPA has been increasingly looking at homeowners, especially their use
of pollution emitting tools like lawn mowers.
The school is proposing two fixes to reduce emissions from
barbecues. First, they want to cut back on grease flare-ups. The idea: “A
slotted and corrugated tray is inserted immediately prior to meat flipping,
and removed immediately after. This short contact time prevents the tray
from over-heating and volatilizing the collected grease. This collected
grease will then drip off into a collection tray and can be used at the pit
master’s discretion.”
But, total capture isn’t “practical,” so a filter and
fan are proposed for installation. “The secondary air filtration system
is composed of a single pipe duct system which contains a specialized
metal filter, a metal fan blade, a drive shaft, and an accompanying power
system with either a motorized or manual method. This system can be powered
by either an exterior electric motor with a chain-driven drive shaft,
directly spinning the fan blade, or a hand-powered crank,” said the project
write-up.
The grant is part of the EPA’s “National Student Design Competition
for Sustainability Focusing on People, Prosperity and the Planet
(2014).”
The expected results, according to the proposal:
“We expect to limit the overall
air pollution PM [particulate matter] emissions from barbecuing and
to alleviate some of the acute health hazards that a barbecue pit master
can experience from inhalation. The particulate matter present during
cooking with and without the grease diverter and PM2.5 filters will be
tested and compared to that of current data using a conventional propane
barbecue using a fumehood chamber with detectors at CE-CERT. Personal
exposure of PM2.5 will also be monitored throughout the experimentation
period to determine the degree of acute exposure of particulates to
the cook.”
