Your definitive expert resource for sustainable, stylish costumes you'll love and rewear
This comprehensive guide is designed to inspire, educate, and empower you to celebrate Halloween without the environmental cost
Why This Matters — Halloween Waste in Numbers
of Halloween costumes contain non-recyclable oil-based plastics
costumes discarded annually in the US alone
of costumes are worn only once
tonnes of plastic waste in the UK - equivalent to 83 million plastic bottles
Halloween has become one of the most wasteful holidays of the year, generating massive environmental damage through single-use costumes and decorations.
Environmental Impact Timeline
The synthetic materials used in most costumes—primarily polyester, nylon, and other petroleum-based fabrics—can take 20-200 years to decompose, meaning every cheap costume purchased today will outlast multiple generations.
When these materials break down, they release harmful chemicals into soil and waterways, while contributing to the growing microplastic pollution crisis affecting marine ecosystems.
The Financial Scale
- $11.6 billion in total Halloween spending expected for 2024
- $3.8 billion on costumes alone
- 5.4 million kilograms of textile waste from Halloween costumes annually
- Less than 1% of these materials recycled into new garments
By switching to eco-friendly alternatives—costumes made from natural fibers, organic cotton, or DIY repurposed materials—you can significantly reduce this environmental impact while often saving money and creating more unique, personal looks.
