It may happen by accident. After cooking a batch of bacon, a tiny amount of grease slips out of a pan and into the sink drain. Perhaps the intent was to dump the grease into another container first and then rinse the pan under the tap, but instead, it went right down the drain.
The problems with this can happen even to those who have good grease etiquette. That is, instead of letting a kitchen sink get clogged with grease, a person actively works to drain pans with grease into jars or into the trash.
In their travels, these bits of grease form into cave-like substances known as stalactites. These substances can cause sewer systems to back up and overflow creating a serious environmental hazard.
A team of researchers at North Carolina State University are observing these substances. They hope to be able to find out more about how they build up and break down chemically so that policies can be implemented in large cities where this problem of grease build-up is most prevalent.
In the meantime, most any restaurant owner or home dweller will want to take care to keep from having a kitchen sink stopped up with grease on their hands. As often as possible, always dump grease or fat runoff from cooked meats into jars. These can be reused to cook some foods again.
Another option for avoiding a kitchen sink clogged with grease is to simply dump the grease into the trash. Restaurants must adhere to grease control rules that are in place in various local communities. It should be noted that some residue may still end up in the sewer as pans are washed.
The grease in question comes from households and restaurants. Citizens are routinely asked to dispose of their cooking grease, oil and fat in the trash instead of the sink, but even in the most conscientious households, some usually manages to slip out with the wash water.
“People try to discharge their oil and grease properly, but over time, you can get a fair amount of oil and grease from washing pots, pans and dishware,” Ducoste told LiveScience. “The cumulative impact could be substantial. It’s that long-term consistent discharge of that oil and grease, even if it’s a small amount at a time, which could lead to problems.”
The problem gets worse in areas with high populations or large numbers of restaurants. Ultimately, Ducoste said in a statement, “if we know how — and how quickly — these deposits form, it may provide scientific data to support policy decisions related to preventing sewer overflows.Read Whole Article Here“
