London's Sewer-Blocking 'Fatbergs' Are Going to Be Turned Into Biodiesel

UK officials can't exactly transform the Whitechapel fatberg—a 143-ton trash mass lurking in London's sewer system—into treasure, but they can turn it into fuel. As The Guardian reports, Scottish biodiesel producer Argent Energy plans to convert parts of the noxious blockage into an environmentally friendly energy source.

For the uninitiated, fatbergs (which get their names from a portmanteau of "fat" and "icebergs") are giant, solid blobs of congealed fat, oil, grease, wet wipes, and sanitary products. They form in sewers when people dump cooking byproducts down drains, or in oceans when ships release waste products like palm oil. These sticky substances combine with floating litter to form what could be described as garbage heaps on steroids.

Fatbergs wash up on beaches, muck up city infrastructures, and are sometimes even removed with cranes from sewer pipes as a last resort. Few—if any—fatbergs, however, appear to be as potentially lethal as the one workers recently discovered under London's Whitechapel neighborhood. In a news release, private utility company Thames Water described the toxic mass as "one of the largest ever found, with the extreme rock-solid mass of wet wipes, nappies, fat and oil weighing the same as 11 double-decker buses."

Ick factor aside, the Whitechapel fatberg currently blocks a stretch of Victorian sewer more than twice the length of two fields from London's Wembley Stadium. Engineers with jet hoses are working seven days a week to break up the fatberg before sucking it out with tankers. But even with high-pressure streams, the job is still akin to "trying to break up concrete," says Matt Rimmer, Thames Water's head of waste networks.

The project is slated to end in October. But instead of simply disposing of the Whitechapel fatberg, officials want to make use of it. Argent Energy—which has in the past relied on sources like rancid mayonnaise and old soup stock—plans to process fatberg sludge into more than 2600 gallons of biodiesel, creating "enough environmentally friendly energy to power 350 double-decker Routemaster buses for a day," according to Thames Water.

"Even though they are our worst enemy, and we want them dead completely, bringing fatbergs back to life when we do find them in the form of biodiesel is a far better solution for everyone," said company official Alex Saunders.

In addition to powering buses, the Whitechapel fatberg may also become an unlikely cultural touchstone: The Museum of London is working with Thames Water to acquire a chunk of the fatberg, according to BBC News. The waste exhibit will represent just one of the many challenges facing cities, and remind visitors that they are ultimately responsible for the fatberg phenomenon.

"When it comes to preventing fatbergs, everyone has a role to play," Rimmer says. "Yes, a lot of the fat comes from food outlets, but the wipes and sanitary items are far more likely to be from domestic properties. The sewers are not an abyss for household rubbish."

If You Want Your Cat to Poop Out More Hairballs, Try Feeding It Beets

Have you ever wondered if there’s a way to get your cat to poop out its hairballs instead of hacking them up? If so, you’re likely a seasoned cat owner whose tolerance for gross stuff has reached the point of no return. Luckily, there may be an easy way to get your cat to dispose of hairballs in the litter box instead of on your carpet, according to one study.

The paper, published in the Journal of Physiology and Animal Nutrition, followed the diets of 18 mixed-breed short-haired cats over a month. Some cats were fed straight kibble, while others were given helpings of beet pulp along with their regular meals. The researchers suspected that beets, a good source of fiber, would help move any ingested hair through the cats’ digestive systems, thus preventing it from coming back up the way it went in. Following the experiment, they found that the cats with the beet diet did indeed poop more.

The scientists didn’t measure how many hairballs the cats were coughing up during this period, so it's possible that pooping out more of them didn’t stop cats from puking them up at the same rate. But considering hairballs are a matter of digestive health, more regular bowel movements likely reduced the chance that cats would barf them up. The cat body is equipped to process large amounts of hair: According to experts, healthy cats should only be hacking hairballs once or twice a year.

If you find them around your home more frequently than that, it's a good idea to up your cat's fiber intake. Raw beet pulp is just one way to introduce fiber into your pet's diet; certain supplements for cats work just as well and actually contain beet pulp as a fiber source. Stephanie Liff, a veterinarian at Pure Paws Veterinary Care in New York, recommends psyllium powder to her patients. Another option for dealing with hairballs is the vegetable-oil based digestive lubricant Laxatone: According to Dr. Liff, this can "help to move hairballs in the correct direction."

Don't Pour Alcohol on Your Bed Bugs—Try These Tips Instead

Getting bed bugs is a nightmare experience, one that’s sure to cost you oodles of time, money, and emotional distress. The bugs are painfully hard to purge from your household, and it’s getting even harder as they become more resistant to common insecticides. Unfortunately, home remedies are often no match for these parasitic insects. Dousing them with rubbing alcohol (a tip you'll often hear) won’t kill them; in fact, it might just burn your house down, as a woman trying to rid her Cincinnati apartment of bed bugs found out recently. As The Washington Post reported, the alcohol in that case was too close to the flame of a candle or some type of incense, and ignited. It wasn't an isolated incident.

In the last 10 years or so, people trying to kill bed bugs with alcohol have started several house fires across the U.S., including a different incident in Cincinnati just two weeks ago. So short of burning down your entire house and starting over, how do you get rid of them?

The short answer is: Give up on the idea of saving money and call an exterminator. According to 2014 research, plenty of DIY bed bug-killing remedies are woefully ineffective. Rubbing alcohol, in fact, only killed half of the insects sprayed by the Rutgers University researchers in that study. Researchers have found that other recommended home remedies, like moth balls, foggers, or ultrasonic bug repellers, are even less effective. And don’t even think about using “natural” type products that use essential oils as the main ingredient. They might smell nice, but they won’t help your bug problem.

But before you call in the big guns, there are a few effective, concrete steps you can take to reduce your infestation. As Rutgers bedbug specialists Changlu Wang and Richard Cooper wrote in their bed bug fact sheet, putting your belongings in plastic storage bins or garbage bags is a good place to start. Since the bugs don’t like to climb on smooth plastic, this can help contain the infestation. Just make sure to treat whatever you’re putting inside the bags or bins first by putting them through the hot laundry, steaming, heating, or freezing them.

You’ll need a mattress encasement, too. This will keep the bugs that have already infested your mattress from escaping, meaning they won’t be able to feast on you anymore and will die of starvation. Nor will any new bugs be able to get inside to nest. You’ll want to make sure it’s a scientifically tested brand, though, since not all mattress encasements are bite-proof or escape-proof for bed bugs. (Most experts recommend the Protect-a-Bed BugLock encasement, which costs about $81 for the queen-sized version.)

Next, pick up some bed bug traps. Set them up under the legs of your furniture and around the perimeter of rooms to help detect new infestations and reduce existing ones. According to Wang and Cooper, a one-bedroom apartment might need eight to 12 of these traps, while bigger apartments will require more.

You’ll want to expose all your belongings to extreme temperatures before you even think about touching them again. Putting them through the washer/dryer on its hottest setting will do the trick to kill both bugs and their eggs, but if you need to eradicate bugs lurking in items you can’t wash, you can freeze them in plastic bags (as long as your freezer gets down to 0°F). You can also kill them with a steam cleaner, especially if you need to purge them from your couch or other upholstered furniture.

If you’ve still got a large number of bugs lurking in your house, you can tackle them with a vacuum cleaner, sucking them out of seams, zippers, trim, and other furniture crevices. But you’ll want to use a stocking or some other method of protecting your vacuum from being infested itself. (See Figure 6 here.)

Some research has also found that desiccant dusts that dehydrate bugs to death, like diatomaceous earth and silica gel, can be effective at controlling bed bug infestations (silica gel in particular) when spread around the perimeters of rooms, on bed frames and couches, and on furniture legs.

As we mentioned before, you’ll probably want to consult a professional even if you do all of the above, because if you miss even one bug or egg, you'll be back to where you started. The cost of an exterminator pales in comparison to the cost of throwing out everything you own, moving homes, and then realizing you’ve brought the bed bugs with you anyway.

The bad news for anyone who’s already infested is that prevention really is key when it comes to bed bugs. So brush up on what the pests look like, make sure to check your hotel room for them when you travel, and if you spot them in your apartment, make sure to warn your neighbors.
