Every October, families rush to pumpkin patches to pick out the perfect gourds. Some use them to carve spooky jack-o'-lanterns, while others place them outside their homes as decor. Unfortunately, the fascination with the colorful fruit fades once Halloween ends, and most pumpkins end up in the trash.

A 2020 poll conducted by the UK-based non-profit Hubbub found that over fifty percent of the 24 million Halloween pumpkins that British citizens bought that year were destined for the landfill. Things are no better in the US, where about a billion pounds of pumpkins get tossed out and left to rot in landfills annually. In addition to the massive amount of food waste generated, the rotting fruit also emits large amounts of methane — a greenhouse gas even more potent than carbon dioxide.

Fortunately, this pollution problem is easy to solve. We can all help eliminate the food waste by keeping the edible portions of the fruit during carving. Roasted pumpkin seeds make a nutritious snack, while the flesh can be transformed into a delicious soup, a tasty puree, or a lip-smacking pie.

Once Halloween is over, drop your jack-o'-lanterns at a local compost collection center if possible. Better still, see if your city or town hosts a pumpkin smashing event and have fun tossing yours on the ground with your friends. Don't worry, the remains will be collected and composted once all the gourds have been smashed.

There are many other ways to ensure the fruit does not end up in landfills. Fill your hollowed-out pumpkins with grains and leave them in the yard or hanging from a tree for birds, squirrels, and other garden critters to enjoy. If your pumpkin is too far gone to salvage, bury it in your backyard — your garden will be all the happier for it.

Have a safe and sustainable Halloween!
