I. Introduction
Importance of composting shredded paper
Composting is an environmentally friendly way to recycle organic waste, including shredded paper. It helps reduce landfill waste, greenhouse gases, and the demand for virgin materials. Composting paper not only contributes to a greener environment but also provides nutrient-rich fertiliser for your garden.
Comparing recycling vs. composting shredded paper
Recycling and composting are both sustainable ways to manage paper waste. However, there are some differences between the two processes. For instance, recycling paper involves breaking it down into fibres and then reusing them to create new products. Composting, on the other hand, breaks down paper waste into nutrient-rich humus that can be used to enrich soil.
II. Benefits of Composting Shredded Paper
Great source of carbon
Shredded paper is an excellent source of carbon, also known as “brown materials” in the composting process. These materials help to balance the nitrogen-rich “green materials” like fruit and vegetable scraps, creating a healthy environment for microorganisms to break down the waste.
Helps soil retain moisture
Adding shredded paper to your compost can help the soil retain moisture, which is especially useful during dry seasons. This not only helps plants grow better but also conserves water resources.
Boosts soil volume
Composting shredded paper adds bulk to the soil, which improves its structure and promotes healthy root growth for plants.
Worms love it
Worms are attracted to compost heaps containing shredded paper. These beneficial creatures help break down the waste, aerate the soil, and provide nutrient-rich fertiliser in the form of worm castings.
III. Types of Paper Safe for Composting
Newsprint
Non-glossy newsprint, like newspapers and flyers, can be safely composted.
Cardboard
Non-waxed, non-glossy cardboard, such as corrugated boxes, can be composted. Be sure to remove any tape or staples before adding it to your compost pile.
Egg cartons
Non-glossy, non-waxed egg cartons made of paper or cardboard are safe for composting.
Toilet paper rolls
Toilet paper rolls, as well as paper towel rolls, are safe for composting.
Non-glossy, non-waxed paper products
Other non-glossy, non-waxed paper products like napkins and paper towels can also be composted.
IV. Types of Paper to Avoid or Use with Caution in Composting
Glossy and waxed paper
Avoid composting glossy or waxed paper, as they may contain chemicals that could harm the composting process or plants.
Printed paper with heavy ink
Printed paper with heavy ink or coloured printing should be used cautiously, as some inks may contain harmful chemicals.
Magazines
Magazines can be composted, but their glossy pages and heavy ink may slow down the decomposition process.
Greaseproof or parchment paper
Greaseproof and parchment paper are generally not recommended for composting, as they can contain grease, oil, or other residues that may harm the composting process.
V. Preparing Paper for Composting
Shredding paper
Shredding paper increases its surface area, allowing it to break down more easily in the compost pile. Cross-cut shredding is an efficient way to shred paper for composting. Learn more about the different types of shredders and how they work on our how paper shredders work page.
Soaking cardboard
Before adding cardboard to your compost, soak it in water to break down the fibres, making it easier for microorganisms to decompose.
Removing non-degradable elements
Remove any non-degradable elements such as tape, staples, or plastic windows from paper products before adding them to your compost pile.
VI. The Carbon-to-Nitrogen Ratio
The ideal ratio for composting
A healthy compost pile should have a carbon-to-nitrogen (C:N) ratio of about 25:1 to 30:1. This balance ensures that microorganisms have the right combination of nutrients to break down the organic materials efficiently.
Balancing the ratio with high-nitrogen materials
To achieve the ideal C:N ratio, combine shredded paper (high in carbon) with green materials like fruit and vegetable scraps, grass clippings, and coffee grounds (high in nitrogen). This helps to balance the nutrients and creates a suitable environment for decomposition.
VII. Composting Methods
Layering method
The layering method involves alternating layers of brown materials (shredded paper) and green materials (garden waste) in your compost bin. This technique helps maintain the proper C:N ratio and promotes efficient decomposition.
Lasagna composting method
Lasagna composting is similar to the layering method but incorporates additional materials such as kitchen scraps, leaves, and garden trimmings. This method creates a nutrient-rich compost that breaks down more quickly.
Aeration and maintenance
Regular aeration of your compost pile ensures that oxygen reaches the microorganisms, which is crucial for efficient decomposition. Turning the pile occasionally and keeping it moist will promote a healthy composting environment.
VIII. Factors Affecting Decomposition Time
Lignin in paper products
Lignin, a natural component of paper, can slow down the decomposition process. However, shredding paper and mixing it with other compost materials can help speed up the process.
Moisture, oxygen, and bacteria
A well-maintained compost pile with the right balance of moisture, oxygen, and bacteria will decompose more quickly. Ensure your compost pile remains moist and aerated for best results.
Estimation of composting time
The time it takes for paper products to decompose in a compost pile can vary depending on factors such as the type of paper, environmental conditions, and composting methods used. Generally, it can take anywhere from a few months to over a year for paper products to break down completely.
IX. Sustainable Alternatives to Paper Products
Compostable packaging
Switching to compostable packaging is a more sustainable option for businesses and consumers. These products can be composted along with other organic waste, reducing their environmental impact.
Eco-friendly packaging
Eco-friendly packaging made from recycled or sustainable materials can help reduce the demand for virgin paper products and decrease the overall environmental impact of packaging waste.
Recycled and organic materials
Using recycled and organic materials for paper products is another way to promote sustainability and reduce the environmental impact of paper waste.
X. Conclusion
Encouragement to compost paper products
Composting shredded paper is a simple and effective way to reduce paper waste and create a nutrient-rich fertiliser for your garden. It promotes sustainability and helps conserve valuable resources, making it a responsible choice for both individuals and businesses.

FAQS
Q: How long does shredded paper take to compost?
A: The time it takes for shredded paper to compost can vary depending on factors such as the type of paper, environmental conditions, and composting methods used. Generally, it can take anywhere from a few months to over a year for shredded paper to break down completely.
Q: Can you compost shredded paper with ink?
A: It’s generally safe to compost paper with soy-based or vegetable-based inks. However, it’s best to avoid composting paper with heavy ink coverage or glossy finishes, as they may contain chemicals that could harm your compost or garden.
Q: Mixing shredded paper into soil?
A: Mixing shredded paper into your soil can help improve soil structure, moisture retention, and overall soil health. However, it’s essential to balance the carbon-rich shredded paper with nitrogen-rich materials, such as green garden waste, to ensure a healthy composting environment.
Q: Grass clippings and shredded paper?
A: Combining grass clippings (high in nitrogen) with shredded paper (high in carbon) in your compost pile helps maintain the proper carbon-to-nitrogen ratio and promotes efficient decomposition. Layering these materials or using the lasagna composting method can create nutrient-rich compost for your garden.
Q: Shredded paper as fertilizer?
A: Shredded paper can act as a source of carbon and help improve soil structure when composted correctly. Although it doesn’t provide all the nutrients needed for plants, when combined with other compost materials, it contributes to creating a nutrient-rich compost that can be used as a natural fertilizer for your garden.
