After use, wet wipes are usually tossed in the trash bin or flushed down the toilet. Either option has hefty consequences. Flushing wet wipes actually causes problems for sewer systems due to not breaking down as easily as toilet paper (namely because they contain plastics). So instead of coming apart, wet wipes accumulate in pipes and catch any oils or fats that come their way. The more wet wipes get thrown in the toilet, the more they grow in the sewers until they become blockages known as "fatbergs." These congealed lumps of non-biodegradable matter can reach tens of thousands of pounds and cost any city unfortunate enough to have them millions.
What about the wet wipes that get hauled off to landfills? They’re no better. Wet wipes contain a dangerous cocktail of preservatives, alcohol, fragrances, and moisturizing and cleaning agents. This makes incredibly effective at eliminating bacteria, to the point where they kill off the bacteria and enzymes that help break down the solid waste in landfills. Composting them won’t be of much help since wet wipes take a long time to degrade, if at all.
Then there’s the matter of what happens if and when wet wipes break down. Simply put, they don’t. Not completely. Wet wipes turn into microplastics over time, which are essentially tiny bits of plastic nearly invisible to the naked eye. They’ve been the subject of much research because of their impact on marine life forms. According to Dr. Sean Anderson, California State University, Channel Islands associate professor of environmental science and resource management, animals that eat microplastics by accident suffer for it.
"Microfibers and microplastics can displace critters' natural food and natural behavior. The critter may need to work more and use more energy; it may block their intestinal tracts," explained Anderson. "This stuff is a sign of the weight of our footprint on our planet."
And instead of just staying in the ocean, microplastics can make their way back to us through the food we eat. As per Romper.com, University of California, Davis researchers discovered that about a quarter of the fish sampled from Californian and Indonesian fish markets are loaded with "man-made debris" such as plastics. The exact effects of microplastics on the human body has yet to be fully established, but some researchers think that they may cause inflammation or toxicity.
