Soy reduces pork emissions

On a lighter news, if you want your meat to have lesser carbon footprint, find out if the pork you’re eating comes from a swine barn sprayed with soybean oil.

You heard it right. Not only is soybean oil being used to make your pork deliciously fried, it can also address dust and odor problems within hog facilities. In a study conducted by Purdue University and University of Missouri researchers, soybean oil-treated swine barn showed an average 20% decrease in methane emissions and a 19% average reduction in carbon dioxide emissions during a 12-month period.

The treated barn emitted about 65 percent less particulate matter than the untreated barn. Researchers suspected controlling dust also would lead to reduced greenhouse gas escapes.

Some of the challenges using soybean oil in treating swine barn are costs, clean-up process which is said to be more difficult (and more expensive), and other minor technical difficulties, which the researchers said can be overcome with good engineering.

Apparently, more research is still needed to make it economically feasible.
