The Environmentally Responsible Way to Dispose of Your Clunker

by

Access to a vehicle is a vital part of the daily routine for many of us residing in the US. Now, more than ever, we must consider the negative effects vehicles have on our environment. After all, we hear about greenhouse gas emissions and global warming daily. Ideally, not possessing a vehicle is the most earth-friendly option. In addition to saving on costs associated with vehicles such as car payments, auto insurance, fuel, and maintenance, our environment is spared some harm in the form of various pollutants cars produce.

Many times, however, regular use of a vehicle is necessary due to local infrastructure. Unfortunately, mobile sources such as cars, buses, and trucks are our main sources of air pollution, per the National Park Service. These types of vehicles account for more than half of all the air pollution in the US. Not surprisingly, automobiles are the top producer of the group.

The salvage yard- a vehicle disposal option fit for some.

You’ve probably heard of auto salvage yards. These businesses purchase junk vehicles from owners who no longer want them. Some salvage yards dismantle the vehicles and sell the parts directly to customers. Others invite customers to come track down components they are seeking and remove parts themselves.

This can be a decent option. You can get a small sum of money in your pocket. That eyesore-of-a-vehicle that has been sitting in your driveway, leaking oil, and causing neighborhood curmudgeons great displeasure, can be hauled away. However, there happens to be an option superior to that of part salvaging.

The little-known yet most responsible way to dispose of an old vehicle:  Recycling.

I have to confess, this is quite the novel concept to me. You can actually recycle your vehicle in whole. Essentially, it can be stripped down, shredded, and reusable parts can be sorted and distributed. Cars rank number one, annually, when it comes to recycled products in the world. Interesting, huh?

Passenger vehicles are composed of a variety of recyclable materials.

Cars consist of a variety of materials that can be effectively recycled. SellMax a scrap car service in Oceanside, was kind enough to provide me with a material breakdown of the average passenger vehicle they acquire. Main materials are as follows:

  • ferrous metal- 68 percent
  • plastic- 9 percent
  • non-ferrous metals- 9 percent; glass- 3 percent
  • tires- 3 percent
  • fluids- 2 percent
  • rubber- 2 percent
  • electrical parts 1 percent

I had the pleasure of speaking to a local car recycler in Salt Lake City and they affirmed that steel and iron, the ‘ferrous metal’ category, are the prime components of a passenger vehicle. Steel mills purchase shredded ferrous materials from scrappers. Usually, about 90 percent of the steel and iron that a vehicle was composed of are recycled. The fascinating thing about steel is that it is 100 percent recyclable. Essentially, it can be recycled again and again without its quality being compromised.

Glass is another material that is 100 percent recyclable. It is one of the most sustainable materials on earth. Like steel, it can be melted down, repeatedly, without its quality being reduced.

Tires are another component that can be recycled and reused for many purposes, such as gravel substitute, playground flooring, and garden mulch, to name a few. Check out this article at nerc.org for additional uses and more details. One caveat with recycling tires is that they’re a significant source of micro plastic pollution. The good news is that we are coming out with better ways to recycle tires often. For instance, Katherine Gallagher of Treehugger states, “As recently as 2020, a team of chemists at McMaster University discovered a way to break down the rubber used in car tires to turn them into new ones. This innovative method, which consists of dissolving the polymeric oils by separating the sulfur-to-sulfur bond in the tires, is a promising step for the future of recycling.”

Recycling car materials can be beneficial in even more ways than you’d think

The environment considerably benefits from recycling of a variety of materials that make up passenger vehicles. According to the EPA, recycling metal uses about 74 percent less energy than making new steel. Recycling of rubber tires reduces dumping of worn tires in landfills, lakes, and other undesirable locations, per Recycled Rubber Facts. More than 90 percent of tires are being recycled and reused each year. As a result, large amounts of energy are saved, and greenhouse gas emissions are reduced.

The Automotive Recycler’s Association (ARA) has estimated that 24 million gallons of motor oil, 8 million gallons of gasoline and diesel fuel, 8 million gallons of engine coolant, and 5 million gallons of windshield washer fluid are collected annually, resulting in a reduction of air and water pollution.

Another favorable aspect of vehicle recycling is the positive impact it has on our economy. Additional data produced by the ARA asserts that the auto recycling industry employs more than 140,000 US workers at more than 9,000 locations around the country.

The takeaway…

It’s probably safe to say that the statistics clearly support the argument that vehicle recycling is the best way to dispose of an old car. The future of our environment looks a bit more promising if we consider the fact that nearly 12 million cars are recycled in the US each year. We can each do our part. We can continue to reduce, reuse, and recycle. And when the time comes to retire our aged vehicles, we can choose the option to recycle knowing that we have chosen the most environmentally responsible option that will, in fact, make a difference.

You can support Recycle Utah while also recycling your old car by participating in our Donate Your Car program. We partner with a local car recycler, Tear-A-Part Auto, who responsibly reuses/recycles vehicle materials and provides Recycle Utah a cash donation for your vehicle. Visit Recycle Utah’s Donate Your Car page for more information on our program.

Household Hazardous Waste

by

You can’t throw a can of antifreeze in the recycling, but the trash isn’t fit for it either. So, how do you dispose of hazardous products?

Notable hazardous household items are herbicides, pesticides, and oil. The average household in the U.S. contains around 3 to 10 gallons of hazardous material. Do not pour hazardous materials in the sink, on the ground, or put in a dumpster. These materials can contaminate soil, affect water treatment plants, and emit harmful chemicals. Though these chemicals may not be notably harmful in small amounts, accumulating exposure is a serious problem.

It is important to prioritize the management of harmful materials. The optimal choice to avoid these negative consequences is to find a natural alternative. If your car uses conventional oil, look into switching to synthetic and increasing intervals between service appointments. If you are unable to make this switch, be conscious of handling instructions on the label. For latex paints, add kitty litter or sawdust to the container to let it dry out and put it in the garbage. Using products entirely prevents chemicals from seeping into waterways. If some of the product remains, keep it in its original packaging with all labels intact. From here, collect the items in a thick plastic bag to prevent leaks and take it to the 3 Mile Canyon Landfill for proper management. And come to our free Household Hazardous Waste Collection Day on Saturday, April 30, 2022 at the Canyons Cabriolet parking lot!

Growing Food at Home

by

Spring is officially here! It’s time to pull out your gardening equipment and prep those planters. Growing your own produce is a great way to obtain natural, fresh fruits and vegetables, while also avoiding the food miles accompanying most grocery store produce. 8% of an average American’s carbon footprint is from food, with more than a quarter of that coming from the transportation of food. An ambitious gardener that replaces 20% of store-bought food with produce from their garden can reduce their carbon footprint by about 68 lbs of CO2 per year!

Another sustainable gardening practice includes planting pollinator-friendly plants, like cornflower, milkweed, and daisies. Pollinators are vital for the creation and maintenance of the habitats many animals rely on for food and shelter, including us! Approximately 35% of the food and fiber grown throughout the world depends on pollinators. By introducing pollinator-friendly plants into your garden, you can create a thriving, diverse environment.

Support the health of pollinators and yourself by cutting out toxic synthetic fertilizers. These fertilizers contribute very little to the ecosystem and structure of your soil, causing more harm than good. There are high levels of nitrates and nitrites in synthetic fertilizer that contaminate surface water through runoff, as well as decrease the fertility of your soil. Opt for organic fertilizers that are more sustainable and enrich your soil. Consider the health of the environment when gardening to create an area that is beneficial for you and the surrounding ecosystem!

What to Do With Dog Poo?

by

A man’s best friend or an infinite poop-producing machine? As much as we love our canine best friends, they can create a lot of waste. There is not a lot of information or even talk about what to do with their endless waste. Do you put it in the trash bin? You could, but it’s unsustainable and creates an unpleasant smell that no one wants. Can you compost it? Well, it depends.

One solution that has grown popular is Biodegradable poop bags. But one of the major problems with this solution is that these bio bags are meant to be composted, not landfilled, yet that’s where they usually end up. While meant to be better for the environment, sending compostable bags can be worse than sending regular plastic bags. According to a San Francisco zero-waste coordinator, “Anything that goes into the landfill and degrades is worse than something that goes in and doesn’t.” Once they start degrading, they produce methane, a potent greenhouse gas. Compostable bags should be composted(1).

But, where can you compost dog poop? Can you put it in the yard scraps bin? Not necessarily, many municipal composting facilities don’t want dog poop. There is an option of composting the poop yourself, but it’s much more complicated than regular composting. Animal waste contains pathogens that can be harmful to humans, so avoid mixing it with your food scraps. One website will show you step-by-step how you can create your own dog poo composter(2), or buy a pre-made dog poo composter(3). 

Another option is to offer flushable poop bags, but that means facilities would have to flush large amounts of poop down the toilet, overwhelming septic systems, and putting a drain on water when there is already a drought. The other alternative would be for the dog owner to take the poop bag home, which is highly unlikely. Poop also has the potential to become a source of energy. It can be anaerobically digested, where it is broken down into organic materials, producing biogas that can be used for energy and a residue that can be used as compost on plants. Wasatch Resource Recovery, in North Salt Lake, has an anaerobic digester they use to turn organics into energy, but they don’t allow dog poop just yet. 

There is still uncertainty around what is the best solution to deal with dog poop. There are working options, but many require expensive facilities. In Salt Lake City, there are dog poo services that will pick up your dog poop for you, but they ultimately end up dumping their pickings in garbage cans. 

So what is the best method for disposing of dog poo? First, the poop must be picked up. Poop does not just “eventually go away.” It harbors lots of viruses, bacteria, and parasites, many of which are harmful to human health. The best solution for disposal, while not desirable, is to send it to the landfill, a case of catch-22. 

If you decide to use biodegradable bags, you must make sure the bags have undergone rigorous testing to prove their claims. A good sign is if they make a representation of what conditions their products were tested under. Paper bags are also a more sustainable option compared to plastic, but no matter what bag you choose, we, unfortunately, have to throw them in the trash for now. 

In conclusion, I reached out to the sustainability departments in Portland, OR, and Santa Cruz, and my research was confirmed. Both cities also currently have no option for animal waste except to landfill it. For now, it is a waiting game with the best foreseeable option being a biodigester.

The Secret to a Productive Garden

by

My garden exploded last year and I know exactly why. The spinach, arugula, kale and radishes, especially, were out of control. I promised my fellow plot gardeners that I’d reveal my secret this spring. Ready? Biochar.

This ancient soil addendum, once used by pre-Columbian Amazonians, is a solid material obtained from the carbonization of biomass. Ancient civilizations would dig deep trenches, fill them with food and agricultural waste, burn the waste then cover it with soil. The practice of ‘Pyrolysis’ involved the use of very high heat and low oxygen, today produced in specialized capsules. The result? Biochar: a carbon dense, porous, rich, dark and charcoal filled soil.

Studies are showing that this amazing soil amendment helps to absorb and hold water, nutrients, toxicity, in addition to increasing carbon storage. The soil acts as a carbon sink to help absorb our over-abundance of Carbon Dioxide that we humans emit. Hefty roots, higher plant yields, less water usage water and carbon absorption – amazing!

Best yet, a single application of biochar lasts for many years. Home gardeners need less than 10% in the top six inches of soil, often mixed with compost. This includes pots! Mix it in with your hands or a small rake. Fortunately, farmers are starting to catch on to the secret, too. Where to buy it? Most gardening stores carry it and we’re also fortunate to have GoBiochar (www.gobiochar.org) in the area. My secret has been revealed and I can’t wait for the next summer 2022 explosion.
