Can recycled plastic products contain hidden toxic chemicals?
Yes. Recycled plastic pellets contained phthalates, organophosphates, and non-phthalate plasticizers at levels that could leach into products made from them.
What's actually in it
Recycled plastic pellets are made by grinding up old plastic products and melting them into new material. Whatever chemicals were in the original products come along for the ride. Flame retardants from electronics, plasticizers from food packaging, and pesticides from agricultural plastic all mix together in the recycling stream.
Products made from recycled plastic, including toys, containers, and household items, can contain a cocktail of chemicals that weren't intentionally added.
What the research says
A 2026 study in Sci Total Environ tested recycled plastic pellets for phthalates, non-phthalate plasticizers, and organophosphate flame retardants.
All three chemical classes were detected in recycled pellets. Phthalates like DEHP and DBP were the most common, carried over from food packaging in the recycling stream.
Organophosphate flame retardants from electronics and furniture were also present. These chemicals weren't supposed to be in food-contact materials, but recycling mixes everything together.
Products made from this recycled material can leach these chemicals during use, especially if they contact food, water, or skin.
