Some traditional nonstick pans can release microscopic particles as they wear down, but how you cook and the materials you choose make a meaningful difference.

This guide focuses on microplastics as physical particles, not chemical PFAS. And while cookware isn’t the primary global source of microplastics, certain materials and cooking habits can contribute over time. The goal isn’t to eliminate every possible exposure. It’s to understand what matters and make practical, informed choices in your kitchen.

Microplastics are small plastic particles that form as larger plastic materials break down over time. While definitions can vary slightly, they’re generally understood to be pieces smaller than five millimeters, and often much smaller at a microscopic level (NOAA).

They come from two main sources:

• Primary microplastics, which are manufactured at a small size (like microbeads once used in cosmetics)

• Secondary microplastics, which result from the gradual breakdown of larger plastic items through heat, friction, sunlight, or general wear

Research shows that microplastics are now present across many parts of daily life, including air, water, and food systems, largely because plastics are so widely used and slow to degrade. Once formed, these particles can persist in the environment and continue to fragment into even smaller pieces over time (National Library of Medicine, 2023).

In the context of cookware, the key distinction is that microplastics are physical particles, not chemical compounds. That means they’re tied to materials that contain plastic components and how those materials wear down with use, rather than being inherent to all cookware.

Not all cookware behaves the same way. Whether microplastics are a concern depends largely on the material and how it’s used.

Traditional nonstick (Teflon)

Many conventional nonstick pans use PTFE, a type of fluoropolymer. As a plastic-based coating, PTFE can degrade physically over time.

• Scratching, especially from metal utensils

• Repeated high-heat cooking

• Long-term wear

These factors can increase surface wear and may contribute to the release of microscopic particles over time. The U.S. Food and Drug Administration (FDA) maintains that PTFE cookware is safe when used as intended, but proper use and maintenance are key to preserving performance.

Ceramic nonstick

Ceramic nonstick cookware uses a silica-based coating, a pure form of sand, rather than plastic polymers.

• Does not rely on PTFE or similar materials

• Performs best at low to medium heat

• Offers a smooth cooking surface without plastic-based coatings

Because it is not a plastic-based coating, ceramic nonstick is not associated with microplastic shedding in the same way traditional, PTFE-based coatings can be.

Stainless steel, cast iron, and carbon steel

These materials contain no plastic components.

• Stainless steel relies on technique rather than coatings

• Cast iron and carbon steel build natural cooking surfaces over time

Because there is no applied polymer layer, these materials do not shed microplastics.

In most kitchens, exposure is less about a single product and more about how cookware is used over time.

The biggest contributors tend to be:

• Cooking at excessively high heat: High temperatures can accelerate the breakdown of coated surfaces

• Using metal utensils on nonstick cookware: Scratching weakens the surface and shortens its lifespan

• Cooking on visibly worn or damaged pans: Flaking or degraded coatings are more likely to shed particles

• Holding onto cookware long past its useful life: All materials wear down eventually, especially with daily use

If you’re unsure whether it’s time to replace a pan, look for clear signs of wear:

• Flaking or peeling on the cooking surface

• Deep scratches that expose underlying layers

• Rough or uneven texture where food sticks more easily

• Noticeable loss of nonstick performance

These are practical signals that a pan is no longer performing as intended, regardless of material.

You don’t need to overhaul your kitchen. A few small shifts can make a meaningful difference.

• Use low to medium heat for coated cookware

• Stick to wooden or silicone utensils on nonstick surfaces

• Replace heavily worn pans when performance declines

• Use different materials for different tasks

For example, you might use ceramic nonstick for eggs and vegetables, and switch to stainless steel or a no-coating option like our Titanium Pro pan when cooking at higher heat.

This kind of mix helps reduce wear on any one piece of cookware while giving you better results overall.

Every cookware material has strengths and trade-offs. The goal is to choose what fits your cooking style.

Ceramic nonstick

• Great for everyday cooking and easy cleanup

• Best at low to medium heat

• Uses a plastic-free, PFAS-free coating

Titanium (no coating)

• Built without applied coatings

• Handles high heat and searing

• Durable over long-term use

Stainless steel

• No coating, highly durable

• Ideal for browning and sauces

• Requires cooking technique

Cast iron / enameled cast iron

• Excellent heat retention

• No synthetic coatings

• Heavier, slower to heat

Microplastics can feel like a big, abstract concern. But in the kitchen, the reality is more grounded.

Cookware is just one piece of a much larger picture. And within that piece, the most important factors are simple: what your cookware is made of, how you use it, and when you replace it.

Cooking is already an act of care. Understanding your tools is part of that process. Over time, those small, thoughtful decisions help create a kitchen that feels more intentional, more comfortable, and more aligned with how you want to cook.
