From vegetable scraps to coffee grounds, various items from your kitchen can go straight into your compost pile. But what about disposable plates? Or plastic plates?

You’ve used them for picnics, parties, or just a quick meal when you don’t feel like doing dishes. They’re convenient, but can you compost paper plates? This guide will answer your question and give you a deeper understanding of composting disposable paper plates.

Decoding the Enigma of Composting Paper Plates: An In-Depth Guide

Can You Compost Paper Plates?

Your Doubts About Composting Paper Plates

Composting can sometimes feel like a complex science. You know that it’s an excellent way to recycle kitchen waste, but when it comes to paper plates, you might have some doubts. After all, they’re not exactly the same as food waste like vegetable peels or coffee grounds.

You might be wondering, are paper plates safe to compost? Will they break down in your compost pile or bin? And what about those with colorful designs or glossy coatings – aren’t those treated with chemicals?

You may also be worried about the time it takes for these plates to decompose. Unlike food scraps, paper plates seem so much more substantial and durable, leading you to question if they’ll ever break down into usable compost.

These concerns are completely valid, and before you toss those paper plates into your compost bin, it’s essential to get accurate information.

The last thing you want is to compromise the quality of your compost or harm your garden with toxic substances unknowingly. This guide is designed to address your doubts, provide clear answers, and empower you to make informed decisions about compostable plates.

The Truth: Can You Compost Paper Plates?

To answer your burning question – yes, you can compost paper plates. In fact, paper plates are an excellent source of carbon, a vital component for the composting process. Carbon-rich materials, often referred to as ‘browns,’ help balance out the nitrogen-rich ‘greens’ like vegetable scraps and coffee grounds.

However, it’s not as straightforward as tossing all your used paper plates into the compost pile. Some considerations need to be made. Not all paper plates are created equal, and some may not be suitable for composting.

Plain, uncoated paper plates are the best for composting. These are generally safe and will decompose reasonably quickly. They’re free from any plastic or wax coatings, making them an excellent addition to your compost heap. Bamboo plates are another variety of compostable paper plates.

However, if the paper plates are glossy, or if they’re coated with plastic or wax, things get a bit more complicated. These coatings are added during the manufacturing process to make the plates more durable and resistant to food and liquid, but they can also slow down the decomposition process and potentially introduce unwanted chemicals into your compost.

Similarly, paper plates with colorful designs or prints can be problematic. The inks used in these designs can sometimes contain heavy metals or other harmful substances. While many companies now use soy-based inks that are safer for composting, it’s not always easy to tell what kind of ink has been used.

So, while you can compost paper plates, it’s crucial to be discerning about what types of plates you’re adding to your compost pile. Stick to plain, uncoated plates where possible, and if in doubt, it might be safer to leave them out.

What You Need to Know: Coatings on Paper Plates

One of the biggest concerns when composting paper plates is the presence of coatings. Many paper plates are coated with a thin layer of plastic or wax to make them more resistant to liquids. While this makes them great for serving food, it also complicates the composting process.

Plastic-coated paper plates are the most problematic. The protective layer of plastic coating is not compostable and will not break down in your compost pile. Worse, it can introduce microplastics into your compost, which can then end up in your garden soil. Microplastics are a significant environmental concern and can harm soil health and biodiversity for a very long time.

Wax-coated paper plates are a bit of a grey area. If the wax is petroleum-based, it’s not ideal for composting. However, some plates are coated with vegetable-based or paraffin waxes, which can break down over time. That said, they will decompose much slower than uncoated paper plates and may leave a waxy residue in your compost.

Similarly, paper plates with a glossy finish often have a coating of some sort. This could be a varnish or a type of ink, both of which can slow down decomposition and potentially introduce chemicals into your compost.

The best advice is to stick to plain, uncoated paper plates if you plan to compost them. If the plates are coated, try to identify what kind of coating it is. If it’s plastic or an unknown substance, it’s best to err on the side of caution and not compost them.

If the coating is wax, consider whether you’re willing to wait longer for the plates to decompose and potentially deal with a waxy residue in your compost.

Your Guide: How to Compost Paper Plates

Now that you know what types of paper plates can be composted, let’s go through the process of turning your used biodegradable plates into nutrient-rich compost.

Identify the Type of Plate

As discussed earlier, not all paper plates are suitable for composting. Before adding them to your compost pile, check if they’re coated with plastic or wax. If they are, it might be better to dispose of them in your regular waste or recycling bin. If you’re unsure, the best way to find out is to do a quick water test. Pour some water on the plate. If it beads up and doesn’t soak into the plate, it likely has a plastic or wax coating.

Prepare the Plates

To speed up the composting process, tear the plates into smaller pieces. This increases the surface area and makes it easier for the microorganisms in your compost pile to break down the material. Also, prepare the plates by removing any leftover food residue, especially meats and dairy products to avoid attracting pests.

Add to Your Compost Pile

Add the torn-up paper plates to your compost pile or bin. Remember that paper plates are considered ‘brown’ materials, so you’ll need to balance them with an appropriate amount of ‘green’ natural material like vegetable scraps, coffee grounds, or grass clippings.

Turn Your Compost Regularly

Turning your compost helps speed up the decomposition process by aerating the pile and distributing moisture and heat evenly. Aim to turn your compost once a week.


Patience is key when it comes to composting. Depending on the conditions in your compost pile, it may take anywhere from a few months to over a year for the paper plates to fully decompose.

Tips for You: Speeding Up the Decomposing Process

You’ve added your paper plates to the compost pile, but you’re impatient. You want to see those plates turn into rich, dark compost as soon as possible. Here are some tips to help speed up the decomposition process:

Shred Your Plates

The smaller the pieces, the quicker they will decompose. Tearing your paper plates into small pieces before adding them to the compost pile increases the surface area, allowing for more efficient breakdown by microorganisms.

Balance Your Browns and Greens

Composting requires a balance of carbon-rich ‘browns’ (like your paper plates) and nitrogen-rich ‘greens’ (like vegetable scraps). A good rule of thumb is to aim for a ratio of 3:1 browns to greens. This provides the optimal conditions for organic matter decomposition.

Turn Your Compost Regularly

Turning your compost pile helps distribute heat and moisture evenly, speeding up the decomposition process. Try to turn your pile once a week using a pitchfork or shovel to maintain a healthy compost pile.

Maintain Moisture Levels

Compost needs moisture to decompose effectively, but too much or too little can slow down the process. Your compost pile should be as damp as a wrung-out sponge. If it’s too dry, add some water. If it’s too wet, add more browns to absorb the excess water.

Use a Compost Accelerator

Compost accelerators contain microorganisms that speed up the decomposition process. They can be purchased from garden stores or online.

Other Household Items for the Compost Bin

Here are a few other common disposable items you can toss into your composting bin, some include a link to our article, so be sure to read more about these because there are some important details when composting each of them correctly and safely.


Composting paper plates can be a bit of a challenge. You need to identify the type of plates, prepare them correctly, and balance your compost pile. It requires effort and patience, but is it worth it?

The answer is a resounding yes. Home composting paper plates not only reduces your carbon footprint but also provides your garden with nutrient-rich compost. It’s a win-win situation for both you and the environment.

Remember, the key to successful composting is understanding what you can and cannot compost. Not all paper plates are created equal, and it’s crucial to avoid composting plates coated with plastic or unknown toxic chemicals. Stick to plain, uncoated plates, and you’ll be on your way to creating fantastic compost for your garden.

So next time you’re cleaning up after a picnic or party, don’t just throw those dirty paper plates in the trash. Consider composting them instead. Your garden, and mother nature, will thank you!
