Go Green With a DIY Waste Audit

Go Green With a DIY Waste Audit

Think of landfills as acne on the face of our planet: The more junk we bury, the worse the breakout is. An average person generates 4.5 lbs of waste a day, and the EPA says 75 percent of that could be recycled. On top of that, it's estimated that 21.5 million tons of food waste goes to landfills each year.

Unlike puberty, this problem won't go away with time unless we become conscious about waste. This Earth Day get down and dirty in your dumpsters and perform a waste audit. It's an easy and effective way to measure what you're producing. When it's completed you'll have a better understanding of the waste you create and how to reduce it.

Assess your options

Before diving in, you need to see what options are available for waste diversion in your area. You may already have a curbside bin for recycling and compost, just make sure you know what materials are appropriate for each. Many county websites offer information about local services and resources. Pay attention to the plastic numbers that are accepted in your area because they differ by region.

If you don’t have a municipal recycling or compost hauler then you’ll have to research alternatives. There are a multitude of redemption centers and independent recycling services to choose from. Make sure to take note of exactly what materials each place does take, because not every type of plastic or food waste is accepted. Some local farms may take your compostables, or you could start your own compost pile or bin at home if you have the space.

Understand your habits

Designate a week for the audit and make sure everyone sharing your home understands the process. Make a log for yourself that includes the following categories: item, material, amount and stream. (Stream refers to where the item would be sorted: either landfill, recycling or compost.)

Place the log by the waste bins and record each item as it goes in. Be as specific as possible about the materials and measures. A cereal box, for example, is made up of a plastic bag (landfill), cereal (compostable) and the box itself (recyclable). In that case you would note that each item was sorted into a different bin and estimate the amount of cereal. Make a distinction between pre-consumer (ends of veggies) and post-consumer (uneaten carrots) food waste.

Clean up your act

When you've finished recording you'll have an idea of what's passing through your household. Use your results to adjust your consumption habits.

Are you using a lot of molded plastics that can’t be recycled in your area? Maybe you should buy a reusable cup that can be brought to your favorite coffee shop instead of needing a new one for each visit (many places do not compost the paper cups that are coated with plastic). Few places recycle the types of cups used for iced beverages, but even if you can recycle it, the relatively common practice of shipping the waste to Asia is not very green.

Did no one eat that huge pot of white bean soup or the three bunches of kale from the market? Consider cutting down, or cutting out altogether, the food items you see that are not being touched. Sure, we’d all like to eat healthier, but if no one is actually making beet smoothies then that’s just a weekly waste.

Food packaging often makes up a large part of household waste. This is where a steady relationship with local farmers and vendors can come in handy. Farmers markets allow you to bring reusable bags to pack up produce, rather than buying it prepackaged in plastic, or worse, Styrofoam. Farmers that do use packaging—those little green plastic baskets that are often used for berries, for example—may be open to taking it back once you are finished with it. If markets are not easily accessible then consider buying in bulk.

Seek out options that work for you and remember that a zero waste lifestyle doesn't develop overnight. Small changes to your habits can have a huge impact over time.

Just in time for Halloween, scientists at Cornell University have published some frightening research, especially if you're an insect!

The ghoulishly named ogre-faced spider can "hear" with its legs and use that ability to catch insects flying behind it, the study published in Current Biology Thursday concluded.

"Spiders are sensitive to airborne sound," Cornell professor emeritus Dr. Charles Walcott, who was not involved with the study, told the Cornell Chronicle. "That's the big message really."

The net-casting, ogre-faced spider (Deinopis spinosa) has a unique hunting strategy, as study coauthor Cornell University postdoctoral researcher Jay Stafstrom explained in a video.

They hunt only at night using a special kind of web: an A-shaped frame made from non-sticky silk that supports a fuzzy rectangle that they hold with their front forelegs and use to trap prey.

They do this in two ways. In a maneuver called a "forward strike," they pounce down on prey moving beneath them on the ground. This is enabled by their large eyes — the biggest of any spider. These eyes give them 2,000 times the night vision that we have, Science explained.

But the spiders can also perform a move called the "backward strike," Stafstrom explained, in which they reach their legs behind them and catch insects flying through the air.

"So here comes a flying bug and somehow the spider gets information on the sound direction and its distance. The spiders time the 200-millisecond leap if the fly is within its capture zone – much like an over-the-shoulder catch. The spider gets its prey. They're accurate," coauthor Ronald Hoy, the D & D Joslovitz Merksamer Professor in the Department of Neurobiology and Behavior in the College of Arts and Sciences, told the Cornell Chronicle.

What the researchers wanted to understand was how the spiders could tell what was moving behind them when they have no ears.

It isn't a question of peripheral vision. In a 2016 study, the same team blindfolded the spiders and sent them out to hunt, Science explained. This prevented the spiders from making their forward strikes, but they were still able to catch prey using the backwards strike. The researchers thought the spiders were "hearing" their prey with the sensors on the tips of their legs. All spiders have these sensors, but scientists had previously thought they were only able to detect vibrations through surfaces, not sounds in the air.

To test how well the ogre-faced spiders could actually hear, the researchers conducted a two-part experiment.

First, they inserted electrodes into removed spider legs and into the brains of intact spiders. They put the spiders and the legs into a vibration-proof booth and played sounds from two meters (approximately 6.5 feet) away. The spiders and the legs responded to sounds from 100 hertz to 10,000 hertz.

Next, they played the five sounds that had triggered the biggest response to 25 spiders in the wild and 51 spiders in the lab. More than half the spiders did the "backward strike" move when they heard sounds that have a lower frequency similar to insect wing beats. When the higher frequency sounds were played, the spiders did not move. This suggests the higher frequencies may mimic the sounds of predators like birds.

University of Cincinnati spider behavioral ecologist George Uetz told Science that the results were a "surprise" that indicated science has much to learn about spiders as a whole. Because all spiders have these receptors on their legs, it is possible that all spiders can hear. This theory was first put forward by Walcott 60 years ago, but was dismissed at the time, according to the Cornell Chronicle. But studies of other spiders have turned up further evidence since. A 2016 study found that a kind of jumping spider can pick up sonic vibrations in the air.

"We don't know diddly about spiders," Uetz told Science. "They are much more complex than people ever thought they were."

Learning more provides scientists with an opportunity to study their sensory abilities in order to improve technology like bio-sensors, directional microphones and visual processing algorithms, Stafstrom told CNN.

Hoy agreed.

"The point is any understudied, underappreciated group has fascinating lives, even a yucky spider, and we can learn something from it," he told CNN.
