What Is Type 7 "Other" Plastic—and Should You Avoid It?

When you flip over a plastic container and see the number 7 inside the recycling triangle, you’re looking at what’s known as "Type 7 – Other." Unlike plastics numbered 1 through 6, which are more clearly defined, Type 7 is a catch-all category. It includes newer plastics, bioplastics made from plant-based materials like corn, and products made by combining different types of plastics that don’t fit into other categories.

One of the most concerning materials under this label is polycarbonate (PC), which often contains BPA (Bisphenol A). This chemical has been linked to hormonal disruptions and other health issues, especially when the plastic is heated or worn down over time. Because of this, experts often recommend steering clear of polycarbonate containers—especially if they’re meant to hold food or drinks. While some Type 7 plastics are innovative—like compostable bioplastics designed to reduce environmental impact—others pose real health and recycling challenges. The problem is, "other" doesn’t just mean different—it often means less transparent. Many recycling centers won’t accept Type 7 plastics due to uncertainty about their composition, which means they’re more likely to end up in landfills or the environment. The best approach? Read labels carefully. Avoid any marked "PC" or recycling code 7 if you're using them for food or beverages. Opt instead for safer, more recyclable materials like glass or plastics labeled 1, 2, 4, or 5 when possible. When in doubt, especially with reusable items like water bottles or food storage, choosing BPA-free alternatives is a small step that can make a big difference over time.
