Can You Compost Envelopes? A Simple Guide to Sustainable Recycling

In our efforts to live more sustainably, composting has become an increasingly popular way to reduce waste and create nutrient-rich soil for plants.

Many of us are familiar with composting food scraps, leaves, and yard waste, but what about envelopes? Can they be composted too?

In this article, we will explore whether envelopes can be safely composted and provide some guidance on how to go about it.

Understanding Envelopes

Envelopes are commonly made from paper, which comes from trees. However, not all envelopes are created equal.

Some envelopes have additional features like plastic windows or adhesive strips. It’s essential to consider these elements when deciding whether or not they can be composted.

Plain Paper Envelopes

If you have plain paper envelopes without any additional features, they can generally be composted. Paper is organic material and will naturally break down in a compost pile.

However, it’s a good idea to shred or tear the envelopes into smaller pieces before adding them to your compost bin. Smaller pieces will decompose more quickly, ensuring a faster and more efficient composting process.

Windowed Envelopes

Many envelopes have plastic windows, which present a challenge for composting. The plastic windows are usually made from materials like polyethylene, which do not break down easily in a composting environment.

It’s best to remove the plastic windows from these envelopes before composting the paper part. You can do this by simply tearing off the plastic or cutting it out. The paper portion can then be composted, while the plastic should be disposed of in your regular recycling bin.

Envelopes with Adhesive Strips

Envelopes with adhesive strips are another common type. These strips often contain materials that are not compostable, such as synthetic adhesives or tapes.

It’s important to remove these adhesive strips before composting the envelopes. Gently tear off or cut out the strip and discard it in the regular trash bin. The remaining paper envelope can then be safely added to your compost.

Colored Envelopes and Glossy Paper

While plain paper envelopes can be composted, it’s important to note that colored envelopes and envelopes made from glossy or coated paper may contain dyes or chemicals that are not suitable for composting.

These materials can take longer to break down and may introduce harmful substances into your compost. It’s best to avoid composting colored or glossy envelopes and instead recycle them through your local recycling program.

Frequently Asked Questions

What paper Cannot be composted?

Certain types of paper should not be composted due to their chemical composition or treatments that hinder the decomposition process. Here are some examples of paper that cannot be composted:

a) Glossy or coated paper: Glossy magazines, brochures, and paper with a shiny coating are typically not suitable for composting. The coating often contains chemicals or materials that impede the natural breakdown of the paper.

b) Colored paper: Colored paper may contain dyes that are not environmentally friendly or may take longer to decompose. It’s best to avoid composting colored paper and recycle it instead.

c) Paper with a high ink content: Paper that has been heavily printed with ink, such as newspapers or flyers, may contain inks that contain toxic substances. These substances can be harmful to plants and soil organisms, so it’s advisable to recycle such paper instead of composting it.

What are 3 things you shouldn’t compost?

While composting is a great way to recycle organic waste, there are certain items that should not be composted. Here are three examples:

a) Meat, dairy, and fish: These food products can attract pests and create unpleasant odors when composted. Additionally, they break down slowly and can introduce pathogens into your compost pile.

b) Oily or greasy food waste: Foods cooked in oil or containing excessive grease should not be composted. Grease and oils can create a barrier in the compost pile, preventing proper airflow and impeding the decomposition process.

c) Pet waste: While composting animal manure from herbivorous animals like cows or horses can be beneficial, pet waste should be avoided. Pet waste may contain harmful bacteria or parasites that can persist in the compost and pose a risk to human health.

What are five items you should not compost?

To ensure a successful and healthy composting process, it’s important to avoid composting certain items. Here are five examples of items you should not compost:

a) Plastic or synthetic materials: Plastic bags, wrappers, or any synthetic materials should never be composted. These items do not break down and can contaminate your compost with microplastics.

b) Diseased or insect-infested plants: Including plants that are diseased or infested with pests in your compost can spread the problems to your garden. It’s best to discard these plants in your regular trash or consult local guidelines for safe disposal.

c) Coal or charcoal ashes: Coal or charcoal ashes should not be composted as they can contain harmful substances, such as heavy metals, which can be detrimental to plant growth.

d) Glossy magazines or coated paper: As mentioned earlier, glossy or coated paper should not be composted due to the presence of chemicals or materials that impede decomposition.

e) Synthetic chemicals or treated wood: Items such as pressure-treated wood, plywood, or anything that has been chemically treated should not be composted. These materials can release harmful substances into your compost, affecting its quality and safety.

By avoiding these items and focusing on organic waste, you can maintain a healthy compost pile and produce nutrient-rich soil for your garden.


Composting is a fantastic way to reduce waste and contribute to a more sustainable future. While plain paper envelopes can be composted, it’s important to consider any additional features such as plastic windows or adhesive strips.

Removing these elements and shredding the envelopes into smaller pieces will help speed up the composting process.

Remember to avoid composting colored or glossy envelopes and recycle them instead.

By being mindful of the materials we compost, we can create nutrient-rich soil and make a positive impact on the environment.
