- They’re kinder to your knives than harder surfaces like glass or steel, but they might require a bit more frequent sharpening than wood boards.
- Always prioritize certifications (GREENGUARD, NSF) and avoid boards with strong chemical smells.
- When you make the right composite board choice, you can be certain that you are cooking safe and not being introduced to exposure to toxins.
- By following these safety measures, the user can avoid exposure to toxins that might be present in unsafe cutting boards.
What Are Composite Cutting Boards?
Composite cutting boards are a popular choice in many kitchens. But what exactly are they? Let’s break it down.
What Are Composite Cutting Boards Made Of?
Composite cutting boards aren’t made from a single piece of material like solid wood. Instead, they’re made by combining different things. Think of it like making a cake – you mix different ingredients to get the final product. These “ingredients” usually include:
- Wood fibers: Tiny pieces of wood, kind of like sawdust, but finer.
- Paper: Sometimes, recycled paper is used.
- Resins: These are like a strong, food-safe glue that holds everything together.
Types of Composite Boards: Bamboo vs. Paper-Resin (Epicurean, Richlite)
There are a couple of main types of composite cutting boards:
- Bamboo cutting boards: These are made from bamboo strips that are pressed and glued together. Bamboo is technically a grass, but it’s very strong and grows quickly, making it a popular sustainable choice.
- Paper-Resin Composites: Brands like Epicurean and Richlite use layers of paper that are soaked in resin and then pressed together under high heat and pressure. This creates a very dense, durable material. The paper-resin composites come in a variety of colors, most notably the orange-brown color cutting boards.
How They’re Made: Binding Processes and Adhesives (Formaldehyde Concerns)
The way composite cutting boards are made is important for safety. The key is the resin, or glue, that’s used.
- The Process: Imagine making a sandwich. You layer the wood fibers or paper, then add the resin. Then, everything is pressed together with a lot of force and heat. This hardens the resin and makes the board strong.
- Formaldehyde Concerns: Some older types of resins used to contain a chemical called formaldehyde. Formaldehyde can be harmful if you breathe in too much of it. This is why it’s important to choose boards that are labeled “formaldehyde-free.” It is important to note that most resins used these days are food safe, and most do not contain formaldehyde.
Are Composite Cutting Boards Toxic?
This is the big question! Are composite cutting boards toxic? The short answer is: it depends on the specific board and how it’s made. But generally, if you choose wisely, they are safe.
Key Chemicals to Watch For
Here are some things to keep in mind:
- Formaldehyde in adhesives: As mentioned, some older adhesives (glues) used to contain formaldehyde. This is less common now, but it’s still a good idea to look for boards that specifically say they are “formaldehyde-free.”
- Microplastics: Good news! Composite cutting boards are not typically made with plastic, so you don’t have to worry about tiny bits of plastic (microplastics) getting into your food. This is a concern with plastic cutting boards, but not with composites.
- BPA and Phthalates: These chemicals are sometimes found in plastics, but they’re rarely used in composite cutting boards. Still, it’s always good to check for certifications (more on that below).
Certifications Matter: GREENGUARD, NSF, and FDA Compliance
The best way to know are composite cutting boards toxic is to look for certifications. These are like gold stars that show the board has been tested and meets certain safety standards.
- GREENGUARD: This certification means the board has low chemical emissions, so it won’t release harmful chemicals into the air.
- NSF: The NSF (National Sanitation Foundation) checks that products are safe for use with food.
- FDA Compliance: The FDA (Food and Drug Administration) in the US sets rules for food safety. A board that’s FDA-compliant meets these rules.
Off-Gassing: Does the Smell Mean Toxins?
Sometimes, new composite cutting boards have a slight smell. This is called “off-gassing.” It’s usually not a sign of dangerous toxins, but it’s a good idea to wash the board thoroughly before using it. If the smell is very strong or doesn’t go away, it’s best to contact the manufacturer.
Composite Cutting Boards and Knives
How do composite cutting boards affect your precious kitchen knives?
How Composite Surfaces Affect Knife Edges
- Gentler than glass/stainless steel but harder than wood: Composite cutting boards are a good middle ground. They’re not as hard as glass or stainless steel cutting boards, which can quickly dull your knife blades. But they’re a bit harder than solid wood boards, which are the gentlest on knives.
- Scratch resistance vs. knife dulling over time: Composite boards are pretty resistant to scratches, which is good for hygiene. However, because they are a bit harder than wood, they might dull your knives slightly faster over time.
Tips to Protect Your Knives
Here’s how to keep your knives in top shape:
- Use sharp blades: A dull knife is actually more dangerous than a sharp one because you have to use more force. Keep your knives sharp!
- Avoid serrated knives: Serrated knives (the ones with jagged edges) can be a bit rough on composite surfaces.
- Regular honing and maintenance: Honing your knife regularly (using a honing steel) will keep the edge aligned and sharp.
Composite vs. Other Materials
Let’s compare composite cutting boards to other popular materials.
| Material | Pros | Cons |
|---|---|---|
| Composite | Durable, eco-friendly, knife-friendly | Potential for toxic glues |
| Plastic | Easy to clean, affordable | Prone to microplastics, scratches |
| Wood | Natural, gentle on knives | Can harbor bacteria if not maintained |
| Bamboo | Sustainable, hard surface | Often uses formaldehyde-based glues |
Composite vs. Plastic: Microplastics and Chemical Leaching
- Composite: No microplastics! Made from wood fibers or paper.
- Plastic: Can shed microplastics, especially as the board gets scratched. Some plastic cutting boards may also leach chemicals over time.
- For people that want to avoid cutting boards made of plastic, composite is a good choice.
Composite vs. Wood: Natural vs. Engineered Safety
- Composite: Engineered for durability and low porosity (meaning it won’t absorb liquids easily).
- Wood: Naturally beautiful and gentle on knives. Some wood types have natural antibacterial properties. However, wood can be more prone to warping and cracking if not cared for properly.
Composite vs. Bamboo: Formaldehyde in Glues
- Composite (paper-resin): Usually formaldehyde-free if you choose certified brands.
- Bamboo: Generally safe, but some bamboo cutting boards use glues that contain small amounts of formaldehyde. Look for “formaldehyde-free” labels.
How to Choose a Non-Toxic Composite Cutting Board
Here’s your checklist for choosing a safe composite cutting board:
Look for These Labels: Formaldehyde-Free, Food-Safe Resins
These are the magic words! Make sure the board is labeled:

Maintaining Your Composite Board
Proper care will keep your composite cutting board safe and in good condition for years.
Cleaning Best Practices: Dishwasher-Safe vs. Hand Wash
- Dishwasher-Safe: Many composite boards, especially the paper-resin types, are dishwasher-safe. This makes cleaning easy!
- Hand Wash: If you prefer to hand wash, use warm soapy water and a scrub brush.
Sanitizing Tips: Hydrogen Peroxide, Vinegar Solutions
To kill bacteria, you can sanitize your board after cleaning:
- Hydrogen Peroxide: Pour a 3% solution of hydrogen peroxide over the board, let it sit for a few minutes, then rinse.
- Vinegar Solution: Mix equal parts water and white vinegar. Spray or wipe the solution onto the board, let it sit for a few minutes, then rinse.
When to Replace: Deep Scratches and Warping
Even the best-cared-for cutting boards don’t last forever. Replace your composite board if:
- It has deep scratches or grooves where bacteria can hide.
- It’s warped or cracked, which can make it unstable and unsafe.
FAQs Composite Cutting Boards Being Toxic
Let’s answer some common questions:
Can composite boards harbor bacteria?
- Non-porous options (like paper-resin composites) are less likely to harbor bacteria than porous materials like wood. However, any scratches or grooves can become a breeding ground for bacteria, so regular cleaning and sanitizing are essential.
Are they safe for cutting raw meat?
- Yes, as long as you sanitize the board properly afterward. It’s always a good idea to have separate boards for raw meat and other foods to prevent cross-contamination.
Do composite boards contain microplastics?
- No! Composite boards are made from natural materials like wood fibers or paper, not plastic. This is a key difference between composite and plastic cutting boards.
