Do products made from recycled plastic contain more toxic chemicals?

What's actually in it

Products labeled "made from recycled plastic" are everywhere now: storage bins, garden furniture, playground equipment, reusable bags, and even food containers. The idea is that recycling old plastic into new products is better for the planet. But recycling doesn't remove the chemicals already in the plastic.

Old plastic carries whatever was mixed into it during its first life: phthalates, flame retardants, UV stabilizers, and other plasticizers. When that plastic gets melted down and reformed, those chemicals come along for the ride. In some cases, mixing different types of recycled plastic actually concentrates the chemicals.

What the research says

A 2026 study in Science of the Total Environment tested recycled plastic pellets (the raw material used to make new products) for phthalates, non-phthalate plasticizers, and organophosphate flame retardants.

The pellets contained measurable levels of all three chemical groups. Phthalates were the most commonly detected, but organophosphate flame retardants showed up too. These are the same chemicals that get banned from children's products, yet they can sneak back in through the recycling stream.

The problem is that recycling mixes plastics from many different sources. A pellet might contain material from old electronics, car dashboards, food packaging, and vinyl flooring, each carrying its own cocktail of additives. The result is a chemical grab bag.

For products that touch food or skin, this is a bigger concern, like recycled plastic cutting boards, food storage containers, or children's playground equipment. Heat, UV light, and physical wear cause these chemicals to leach out over time.

If you want to avoid this chemical roulette, be cautious about recycled plastic items that contact food, drinks, or skin. For food storage, stick with glass or stainless steel. For kids' play areas, natural materials like wood are a safer bet. Recycled plastic is fine for things like park benches or fence posts where chemical leaching matters less.
