What are Brown Paper Bags?

Brown paper bags, a common sight in supermarkets and grocery stores, are typically made from kraft paper.

The term ‘kraft’ comes from the German word ‘kraft,’ meaning ‘strength,’ which is appropriate given the high durability and tear-resistance of these bags. They are often used for carrying groceries or as lunch bags due to their sturdy nature.

The production process of brown paper bags begins with softwood trees like pine, spruce, or fir. These trees are chipped into small pieces, which are then cooked under high pressure in a mixture of water and chemicals.

This process, known as the kraft process, separates the lignin (a complex organic polymer that gives wood its strength) from the cellulose fibers. The result is a strong, brownish pulp that is then rolled out into large sheets to create kraft paper.

One of the main reasons why brown paper bags are brown is because they are unbleached. Unlike white paper bags, which go through a bleaching process to remove the natural color of the wood pulp, brown paper bags retain their natural color.

This makes them more environmentally friendly since the bleaching process uses harmful chemicals that can pollute waterways.

Brown paper bags are not only strong and versatile but also biodegradable and recyclable. But does this mean they can be composted? In the next section, we will delve into this question and explore whether or not brown paper bags can be added to your compost pile.

Can You Compost Brown Paper Bags?

The good news is, yes, you can compost brown paper bags. They are made from a natural material, wood pulp, which is biodegradable and breaks down over time. This makes them an excellent addition to your compost pile.

Brown paper bags fall into the category of “brown” compost materials, which provide carbon for your compost. The carbon in these materials, also known as ‘browns,’ helps to balance the nitrogen-rich ‘greens’ like fruit and vegetable scraps, coffee grounds, and grass clippings. A well-balanced compost pile should have a mix of both ‘greens’ and ‘browns’.

However, it’s critical to note that not all brown paper bags are created equal when it comes to composting. Some may be coated with a thin layer of plastic or wax to increase durability, which does not break down in compost.

Similarly, if the bag has been printed with colored ink, it might contain heavy metals or other toxins that could be harmful to your compost pile and, ultimately, your garden.

Before adding brown paper bags to your compost pile, it’s essential to ensure they are free of these non-compostable elements. If you’re unsure whether your brown paper bags are safe to compost, it’s best to err on the side of caution and leave them out.

The Process of Composting Brown Paper Bags

Composting brown paper bags is a relatively straightforward process, similar to composting other types of ‘browns’ such as leaves or cardboard. Here’s a step-by-step guide on how to do it.

Step 1: Preparing the Brown Paper Bags

Before you add the brown paper bags to your compost pile, you need to prepare them. This involves checking for any plastic or wax coatings and removing any metal staples or handles that won’t decompose. If the bag has colored printing, try to remove those sections if possible to avoid introducing potentially harmful chemicals into your compost.

Step 2: Shredding the Bags

Once you’ve prepared the bags, shred them into smaller pieces. This increases the surface area, making it easier for the microorganisms in your compost pile to break down the material. You can do this by hand or use a shredder if you have one.

Step 3: Adding the Bags to Your Compost Pile

Now you’re ready to add the shredded paper bags to your compost pile. Remember, balance is key in composting. For every part ‘green’ material (like vegetable scraps or grass clippings), you should add about two parts ‘brown’ material (like your shredded paper bags). This helps ensure a good carbon to nitrogen ratio, which is crucial for effective composting.

Step 4: Maintaining Your Compost Pile

After adding the brown paper bags, continue to maintain your compost pile as usual. This includes turning it regularly to aerate it and ensure even decomposition, keeping it moist but not waterlogged, and adding more ‘greens’ and ‘browns’ as necessary.

Step 5: Checking Your Compost

Over time, the brown paper bags will break down along with the other materials in your compost pile. When the compost is ready, it should be dark, crumbly, and smell like earth. If you can still see recognizable pieces of brown paper bag, it may need more time to decompose.

Advantages of Composting Brown Paper Bags

Composting brown paper bags has several advantages that make it a worthwhile practice for both gardeners and environmental enthusiasts alike. Let’s delve into these benefits.

Environmental Benefits

One of the most significant advantages of composting brown paper bags is the positive impact it has on the environment. By composting, you are diverting waste away from landfills where it would otherwise decompose and release methane, a potent greenhouse gas.

Also, since brown paper bags are made from wood pulp, composting them helps to return these natural materials back to the soil, completing the organic life cycle.

Soil Improvement

Brown paper bags, like other “brown” compost materials, are rich in carbon. When composted, they help to improve the structure of your soil, making it more fertile and better at retaining moisture. This can lead to healthier, more vigorous plants in your garden.

Waste Reduction

Composting brown paper bags also contributes to waste reduction. With millions of paper bags used every day around the world, composting provides a practical and eco-friendly way to dispose of these bags instead of sending them to a landfill or recycling facility.


Making your own compost with brown paper bags and other organic waste can save you money on garden soil and fertilizers. Compost is a free, nutrient-rich soil amendment that can enhance the health and productivity of your garden without the need for costly chemical fertilizers.

Challenges and Solutions in Composting Brown Paper Bags

While composting brown paper bags has numerous benefits, it’s not without its challenges. However, with a bit of knowledge and the right approach, these can be easily overcome.

Challenge 1: Plastic or Wax Coatings

Some brown paper bags come with a thin layer of plastic or wax to increase their durability. These coatings do not decompose and can contaminate your compost pile.

Solution: Always check the bag thoroughly before adding it to your compost pile. If you notice a shiny, water-resistant coating on the bag, it’s best to leave it out of your compost.

Challenge 2: Colored Inks

Colored inks used on some paper bags can contain heavy metals or other toxins. When added to compost, these toxins can eventually end up in your garden soil.

Solution: Try to remove sections of the bag with colored printing before composting. If this isn’t possible, it’s better to err on the side of caution and not compost these bags.

Challenge 3: Slow Decomposition

Brown paper bags are high in carbon and can take longer to decompose compared to ‘green’ materials. This can slow down the overall composting process.

Solution: Shred the bags into smaller pieces to speed up decomposition. Maintaining the right balance of ‘greens’ and ‘browns’ and regularly turning your compost pile can also help accelerate the process.

Challenge 4: Attracting Pests

Like any compost pile, if not managed correctly, composting brown paper bags can attract pests like rodents or insects.

Solution: Ensure your compost pile is well-balanced and not too wet. Covering your compost pile with a layer of brown materials like leaves or straw can also help deter pests.
