Is there plastic in coffee cups?
Disposable coffee cups typically have a plastic resin, or polyethylene, lining. Polyethylene is a petroleum-based plastic, requiring thousands of barrels of oil to line our paper cups every single year. Beyond the fossil fuel requirements, single-use plastics present another issue: proper disposal. Like many other kitchen products, the pods and cups used inside these coffee machines often contain plastic materials. Studies find these materials can shed microplastics, which are then released into the coffee—and emerging research suggests that long-term exposure to microplastics in general may compromise health.
Do Starbucks cups have microplastics?
Here’s why 👇 ❌ They’re not just paper: Most of these “paper” cups are also lined with plastics, such as polyethylene, to make them sturdy and waterproof. However, that lining breaks down in hot liquids, releasing millions of hormone-disrupting compounds, including microplastics. The paper cups are lined with wax, plastic, and glue to make them more waterproof, so they don’t break down and spill hot coffee all over you. But this also means they shouldn’t be microwaved. Not only could the plastic and glue melt and become red hot you also don’t want chemicals seeping into your latte.
What cups don’t have microplastics?
For hot drinks, the best option is to use a reusable cup made of stainless steel, ceramic, or glass, as these materials do not shed microplastics. Both the cups and lids are made of fiber-based paper board with a bioplastic liner. The new cups will be rolled out in select markets across 14 states including California. I think it’s a great start and I’m thrilled Starbucks is doing this, said Susan Keefe, director of SoCal Beyond Plastics.Why some locations are eliminating plastic cups. The backstory: For years, Starbucks has faced growing concerns over plastic waste, particularly as cold drinks have surged in popularity. In April 2024, the company announced new cold cups made with up to 20% less plastic.
