The Lifecycle of Foam

by

Packing peanuts, food containers, coffee cups, and packaging material you might know as Styrofoam. In fact, Styrofoam is a Dow company trademarked name for extruded polystyrene foam (XPS) that’s used for insulation purposes. The foam we often encounter when we order large items online or pick up takeout for dinner is expand polystyrene foam (EPS).

Polystyrene is a type of plastic that begins in the manufacturing process as small synthetic beads. The beads are heated and molded to form several types of commonly used plastic, including CD cases, smoke detectors, disposable razors, and other hard plastics. During the heating process, the beads can be expanded and molded to form EPS and XPS foam. EPS and XPS foam are expanded between 40 and 80 percent of the original volume and consist primarily of air. It’s inexpensive to manufacture, simple to transport due to its lightweight nature, and is a semi-durable and reliable product. So, what’s the problem?

EPS and XPS foam are notoriously difficult to recycle due to our municipal recycling infrastructure. In the landfill, it can take around 500 years for it to decompose. When EPS and XPS foam end up in our natural environment, it leaches into our water and soil systems as component cells. The health risks of the component cells in our natural environment are daunting with some experts suspecting them to be carcinogenic.

To help prevent the pollution of EPS and XPS foam in our environment, use alternative products to foam, encourage your local and online businesses to switch to paper products,  and vote for policies and politicians that will create bans of foam in your community.

Our Grocery Choices: Some Recycling Packaging Conundrums

by

We often hear about nixing the plastic bag for a reusable and that’s easy. What about some of the more complex sustainability conundrums as we stroll through the grocery aisles?

  1. Styrofoam: Always looks for an alternative. Eggs? Choose paper. Meat? Buy directly from the butcher.
  2. Yogurt: Small containers or the big tub? Select the big tub unless you won’t be able to finish it to avoid the food waste.
  3. Soup stock: Nix the non-recyclable Tetrapaks (often used for stock and alternative milks). Choose concentrated stock in small glass jars or cubes.
  4. Kid lunch items: The cute single-use items are screaming to be purchased (mini applesauce, juice boxes, Lunchables, etc.), but they are single-use and end up in the landfill. Pack your own goodies in reusable containers and save money.
  5. Coffee and tea: Standard plastic coffee bags that are mixed with paper or metal are not recyclable. Buy in bulk with your own containers or buy coffee in a metal container and avoid using the individual coffee pods. Tea can also be purchased in bulk but if individual bags are preferred, they are compostable. Prioritize teas in paper packaging rather than plastic or mixed-material packaging.

Packaging is complex and ever-changing. If in doubt, always choose paper, metal, or glass over plastic. Plastic was an amazing invention at one point in history, but we are now seeing the environmental repercussions. Glass and metal can be recycled endlessly without degrading in quality. Paper is easily recyclable and usually compostable. It’s the smart choices we make now that will benefit our children down the road.

Recycled Metal is Always Precious

by

Metals are elements mined from ores. Unlike glass and plastics which are produced from natural resources, we can’t make more metal like iron, aluminum, lead, copper. That keeps the demand and value of used metal high. Nearly all metals are infinitely recyclable without degradation. Scrap metal dealers pay recyclers for their scrap metal. They haul Recycle Utah’s mixed metal dumpster to a scrap metal yard where it is sorted, separated from non-metallic material, crushed, and compacted into large blocks. These are transported to a steel mill where they are melted in furnaces into metal sheets and ingots. We should be diligent about recycling metal. Recycled metal is vastly cheaper than mining ore. It significantly reduces manufacturers’ use of natural resources and energy. It provides recyclers some steady income.

So, what metals go into our curbside recycling bins? If it’s metal and food came in it, put it in your bin and make sure it is 90% clean. Labels do not need to be removed. Recycle aluminum cans, trays, pans, and foil. Keep top tabs attached to or inside crushed cans. Put steel and tin cans, metal bottles and caps into your bin as well.

What goes into Recycle Utah’s metals dumpster? Any non-hazardous item containing at least 70% metal! For example: washers, dryers, stoves, microwaves, bed frames, bikes, grills, cast and wrought iron, cans, golf clubs, tools, and car parts.

Reach Out for Sustainably-Produced Goods

by

Demand for recycled materials fluctuates over time. Now, because the demand for cardboard is low, our local recyclers are paying to have it stored. However, cardboard continues to be
diverted from the landfill by our local recyclers and that is an important consideration. (Like food waste, cardboard is biodegradable, and as such, produces methane gas as it breaks down.)

One market trend that remains is consumers opting to purchase sustainably-produced goods.
Sustainable shopping feels good. It reflects our concerns about the environment at a time of
dramatic climate change, visible increases in land, air, and water pollution, a growing
scarcity of natural resources, a decrease in animal populations, and increasing reports of the ill effects of chemical additives to a wide range of products. Our buying more sustainably-
produced goods put pressure on retailers to purchase a larger amount and variety of recycled material. It creates new and different jobs and fosters research and product development.

In order to bolster their authenticity, loyalty, and revenue, retailers are having to pay attention to consumers’ increased demand for sustainable products. It is happening. There are ever more rigorously tested, high-quality sustainably made products for sale. Read their labels and make product comparisons. Choose to be in the growing group of Americans who are shopping sustainably and know by doing so, you are increasing the demand for recycled materials.

The (Un)Sustainability of Tetra Paks

by

“Is this recyclable?”, “Which bin does this go in?”, and “What is this even made of?” are questions us recyclers are often asking ourselves while we examine a package searching for the small recycling symbol and trying to determine the material it’s made of. Recently, packaging has become more obscure with waxy-paper-like rectangular cartons that we find in our local stores containing non-dairy milks, broths, juices, soups, and other foods.

Cartons are made primarily with paperboard and are either aseptic or non-aseptic. Aseptic cartons, or shelf-stable cartons, include paperboard, an internal aluminum layer, and a plastic seal. Non-aseptic cartons, or refrigerated cartons, don’t have the aluminum layer, and thus have a shorter shelf life and require refrigeration.

When compared to glass jars, tin cans, and retort pouches, the aseptic and non-aseptic cartons require less energy to produce and are drastically lighter, making their production and transportation carbon footprint smaller. However, aseptic and non-aseptic cartons are very difficult to recycle due to their mixed-material composition.

Here in Summit County, non-aseptic cartons can be recycled as plastic, but aseptic cartons cannot be recycled due to their aluminum lining. Tetra Pak, the Swedish-Swiss conglomerate producing aseptic cartons, stamp the recycling symbol on their cartons but only 30% of their cartons are actually recycled. Without a machine specialized in separating each material in an aseptic carton, it cannot be recycled. Recycle Utah’s recommendation is to purchase your goods in glass jars and tin cans as those are materials that can be reused and recycled without losing quality.
