How to celebrate a plastic-free Halloween

Halloween is a time for costumes, candy, and creepy fun but it’s also one of the most plastic-heavy holidays of the year that is more trick than treat for our ocean.

From synthetic outfits to single-use sweet wrappers, the spooky season can leave a haunting mark on the environment – and our seas are no exemption. Devil tridents, vampire capes, cat ears, masks, fake cobwebs, and polystyrene pumpkins may help set the spooky scene, but most are made from plastic and used only once. That means that these items often end up in landfills or polluting our waterways and ocean.

However, with a little creativity, you can enjoy all the thrills of Halloween without the plastic waste. So instead of scaring the planet, try these simple swaps to reduce your plastic footprint and keep your Halloween frightfully fun and eco-friendly:

Make Your Own Treats

Skip the plastic-wrapped sweets and whip up homemade goodies like fudge, cookies, or toffee apples. You’ll find plenty of recipes online, and with a bit of smart shopping, you can avoid plastic packaging altogether.

Packaging from crisps, sweets and lollies was the 2nd largest group of items found during our beach cleans in 2024

For trick-or-treaters, you could buy loose sweets like pick 'n mix and serve them in paper bags or compostable containers. Not only will you reduce plastic waste but you will be able to hand out equal proportions to all visitors at the door without worrying about running out before the night is over.

Create your own custom costumes

Shop-bought Halloween costumes are often made from plastics such as polyester and worn only once. Instead, get creative this year with cardboard, old cotton sheets, or curtains. These materials can be recycled or reused next year and guarantees no copy cats.

If you already have a costume or mask, why not reuse it or pass it on for someone else to use next year? Better yet, arrange to swap costumes with friends or family so they can use it next year instead.

Remember you can also buy and donate shop-bought costumes to a charity shop. Just remember to keep the original packaging as charity shops often need fire safety labels to resell items.

Ditch the Wet Wipes

When it does come to removing your makeup or face paint, a simple bar of soap, solid cleanser or plastic-free scrub will do – no need for wet wipes.

You can buy reusable fabric makeup removers, too. Simply wet the cloth under a tap, wipe your face and hey presto! To clean, just rinse under the tap with some soap.

Avoid using disposable tableware

Planning a Halloween party? Try to use reusable plates, cutlery, and glasses to cut down on plastic waste and packaging. Old jam jars can make quirky, ocean-friendly drink glasses and you could even get guests to decorate them with spooky designs for extra flair as a fun activity to do between bobbing for apples and carving a pumpkin.

Consider using eco-friendly cleaning products

After the festivities, clean up with natural, plastic-free products. Use dish soap bars and wooden brushes for washing up, using soaps or washing up liquid made from natural ingredients will also avoid scary chemicals entering our waterways. For spills, you could swap paper towels for reusable cloths or sponge wipes.

Recycle as much as possible after your party

Check your local council’s website to see what can be recycled at home or dropped off at collection points. The more you recycle, the less ends up in landfill or gets blown into rivers and the ocean.
