Food waste is a year-round concern. Still, the large Thanksgiving meal presents a particular challenge when it comes to preventing it. You’re buying many more ingredients. You’re making large-scale recipes, with lots of potential leftovers. You may just be even more preoccupied with everything else going on around you.
But there are ways to reduce food waste and therefore your environmental impact, even around the holidays. Here are a few tips geared toward Thanksgiving dinner.
This Halloween season has come to an end. The trick-or-treaters had their fun and jack-o-lanterns across Chicagoland are getting cleared from stoops.
While throwing these past perfect pumpkins into the trash might seem like a good option, it’s not the best for our planet.
When tossed, pumpkins end up in landfills as food waste. Buried under heaps of trash, they rot and release methane — one of the most potent greenhouse gasses. Food waste makes up 37% of Cook County’s landfill material, according to the University of Illinois Extension.
But there is a very cathartic and environmentally friendly way to dispose of Halloween gourds: a pumpkin smash!
These events are exactly what they sound like — a chance for people to smash their beloved jack-o-lanterns into a compostable mess using a baseball bat or other creative methods. Once smashed, the chunks are transferred to composting sites across Illinois. Composting reduces methane creation and transforms the pumpkins into useful organic material – like nutrients for soil or mulch.
As the Halloween season comes to a close, millions of costumes will begin making their way to landfills, many of which have only been worn a single time. A research report completed by Fairyland Trust and supported by Hubbub examined this Halloween costume waste system and how to potentially reduce the amount of waste sent to landfills.
For many Americans, pumpkins mean that fall is here. In anticipation, coffee shops, restaurants and grocery stores start their pumpkin flavor promotions in late August, a month before autumn officially begins. And shoppers start buying fresh decorative winter produce, such as pumpkins and turban squash, in the hot, sultry days of late summer.
But these fruits – yes, botanically, pumpkins and squash are fruits – don’t last forever. And they may not even make it to Halloween if you buy and carve them too early.
As a plant pathologist, gardener and self-described pumpkin fanatic, I have both boldly succeeded and miserably failed at growing, properly carving and keeping these iconic winter squash in their prime through the end of October. Here are some tips that can help your epic carving outlast the Day of the Dead.
Pick a healthy pumpkin and transport it carefully
This may seem obvious, but shop for a pumpkin in the same way that you shop the produce aisle. Whether you plan to carve them or not, choose pumpkins that are not damaged, dented or diseased. Is the stem loose? Is there a clear break in the rind? Are there any water-soaked spots on the exterior?
Post-harvest diseases – those that occur after the pumpkin is removed from the vine – can happen anywhere between the field where they were grown and your front step. A bruise or crack will allow opportunistic fungi, bacteria, water molds and small insects to invade and colonize your pumpkins. Keeping the rind defect-free and stem intact ensures your prized pumpkin a longer shelf life.
The trip home also matters. Most of us transport pets, kids, muddy hiking boots and food in our cars, which makes our vehicles giant petri dishes harboring common environmental molds and bacteria. Some of those microbes could colonize your unsuspecting pumpkins.
Secure your pumpkins en route to your house so they don’t suffer bruising or stem breakage. My family often uses seat belts to protect ours. Once home, don’t carry your pumpkin by the stem, which can lead to breakage, especially if it is big and heavy.
Keep them clean and dry
Pumpkins spend most of their lives in fields, developing on top of soil that teems with fungi, bacteria, water molds and soil-dwelling animals like nematodes, insects and mites. Removing these organisms, and any eggs they may have affixed to your pumpkin’s rind, will help preserve it.
To get rid of them, wipe down your pumpkins, preferably with a bleach wipe or two. This is especially important if you plan to carve them: Piercing the dirty rind with a sharp tool will introduce these eager visitors deeper into the heart of your pumpkin. Be sure to use clean tools as well. Microbes can reside and multiply on small amounts of pumpkin debris stuck in the teeth of dirty carving knives.
Even if you are not carving your pumpkin, wiping it down isn’t a bad idea, since it may have small bruises or cracks that are easy to overlook.
Hollow pumpkins out thoroughly, but don’t overdo it
Much of the work of carving a pumpkin involves separating the fibrous strands and seeds inside it from the harder pulp that makes up the pumpkin’s walls. As you scoop out the pumpkin’s innards, thoroughly inspect the inside walls for soft rotten patches or dark tissues, which may have been colonized pre- or post-harvest by bacteria, fungi or water molds. Diseased pumpkins sometimes produce an off-putting smell, so use your nose as well.
If you find these issues as you carve, you may want to try carving another pumpkin. You can also paint your pumpkins instead of carving them, which averts the need to peer inside.
Some online tutorials and YouTube videos recommend thinning out pumpkins’ walls to better allow candle or LED light to pass through. But if you make the walls too thin, your jack-o’-lantern’s fangs will become inward-curving skin tabs as the pulp desiccates and deforms. A toothless jack-o’-lantern scares no one.
Another advantage of maintaining thicker walls is that it enables you to try a 3D carving. This involves shaping the pumpkin’s surface as you would carve a piece of wood, without breaking through the shell, and can produce dramatic results.
Some people soak their carved pumpkins in diluted bleach or vinegar water after completing them. But this technique is a double-edged sword: Adding more free moisture to your masterpiece invites windblown mold spores and rain-splashed bacteria to colonize it. However, applying a light coating of petroleum jelly or vegetable oil to all the exposed parts can extend the shelf life of your sculpted squash.
Protect your creation
October is a wet month with frequent rains in many parts of the U.S. Rain falling on your jack-o’-lantern will invite every mold in the neighborhood to take up residency in or on it. For this reason, I recommend keeping your pumpkins on a covered porch or displaying them from indoors in a window.
It’s OK if some mold forms inside it, as not all fungi cause soft rots – diseases that produce wet spots that spread, become mushy and turn black. If a pumpkin does become overly moldy on the inside walls, move it outdoors to avoid producing a lot of spores in your home.
When your pumpkin does start to mold and collapse, don’t throw it in a landfill. Put it out for your neighborhood deer or atop your compost pile. Or find a spot in your yard where you can watch it degrade over time, until it turns back to soil in time for next year’s pumpkin patch.
Resale has taken off among those looking to save the planet and spend less on gifts during what can be the most wasteful time of the year — the December holidays. This year’s supply chain delays have provided extra motivation.
With consumers shopping online more than ever before, Republic Services is bracing for an influx of discarded packaging material during the holiday season and is asking consumers to make sure they are recycling materials correctly. There’s significant need for recycled paper due to the unprecedented demand for household paper products and cardboard during the pandemic.
The holidays will be different this year, but you can create a new tradition that supports the community.
The Center for Biological Diversity’s updated Simplify the Holidays website helps gift-givers think outside the box with gifts and traditions that encourage creativity, increase connection, ease stress, save money, reduce waste and help the environment.
Use the SoKind registry to create wish lists for gifts people want. Both the website and registry include alternative gift idea lists with categories such as homemade gifts, charitable donations, experiences, time and more
