What is made of type 6 plastic?

Everyday Items Made from Plastic #6

When you grab a takeout coffee with a plastic lid, eat with a disposable fork, or pop in a DVD, you're likely handling plastic #6—also known as polystyrene, or more specifically, expanded polystyrene (EPS) and solid polystyrene. This rigid, clear plastic is commonly used in a range of everyday products because of its stiffness and low cost.

Plastic #6 is found in many familiar household and single-use items. Think about disposable plastic cutlery, clear plastic cups for cold drinks, and those rigid lids that seal paper coffee cups. You’ll also find it in CD and DVD cases—remember those transparent plastic cases from the early 2000s?—as well as some types of plastic clothes hangers and food packaging trays.

While convenient, plastic #6 poses serious environmental and health concerns. It’s not easily recyclable in most curbside programs, and when it ends up in landfills or waterways, it breaks down slowly, contributing to long-term pollution. Worse, when burned or heated, polystyrene can release styrene, a chemical linked to health risks with prolonged exposure.

Many cities and countries are now restricting polystyrene products, especially food containers, in favor of more sustainable alternatives. As consumers, being aware of the plastics we use—and choosing reusable or compostable options when possible—can make a real difference.

Next time you reach for a plastic fork or a foam takeout container, take a moment to check the recycling code. If it’s a 6, consider whether there’s a greener alternative at hand. Small choices add up.
