Palm oil is an unusual suspect in creating a tremendous amount of air pollution, according to a CU-Boulder study.

Palm trees may be a symbol of paradise, but campus researchers have discovered a dark side to the tropical icon.

The production of palm oil, used in many cosmetics, soaps, lotions and packaged food, is wreaking havoc on the environment. Methane bubbling from a single palm oil wastewater lagoon in one year is roughly equivalent to the emissions of 22,000 passenger vehicles in the U.S., according to CU-Boulder researchers.

Furthermore, global methane emissions from palm oil wastewater could equal 30 percent of all fossil fuel emissions from Indonesia, a primary exporter of palm oil.

But don鈥檛 boycott your products just yet. The researchers posed a solution to the wastewater problem, published in the聽Nature Climate Change聽journal: use the methane as a renewable energy source.

鈥淭he industry has become a poster child for agriculture鈥檚 downsides, but capturing wastewater methane leaks for energy would be a step in the right direction,鈥� says Philip Taylor, the study鈥檚 lead author and postdoctoral researcher at CU-Boulder鈥檚 .

Captured gas can be used to fuel power plants at a cost comparable to traditional fuels. If collected last year, the amount of methane released could have met the electricity needs of a quarter of Malaysia鈥檚 population of 29 million people.
