Can You Compost Paper Towels?
Unveiling the Truth Behind Disposal Myths
Composting has become a widely accepted practice in sustainable living, and many everyday household items are finding their way into compost bins, including paper towels. They are primarily composed of cellulose fibers derived from plant material, which means they biodegrade rather well. Most paper towels can be composted, providing they haven't been contaminated with substances that are not suitable for composting, such as oils, chemicals, or non-organic matter.
The compostability of a paper towel can depend on its usage and what it has been exposed to. Clean, unused paper towels are excellent for compost as they serve as a source of carbon—a vital ingredient in the composting mixture. Even those lightly soiled with water or organic material like food residues are typically good candidates for composting. However, paper towels used with cleaning chemicals, grease, or to clean up anything potentially harmful to the composting process should be avoided.
In any composting system, the balance between carbon-rich 'browns' and nitrogen-rich 'greens' is crucial for effective decomposition. Paper towels, when added appropriately, can help maintain this balance. While considering their compostability, it's also essential to look for paper towels made from recycled materials, as these are more eco-friendly choices that complement the composting ethos of reducing waste and promoting a closed-loop system.
Understanding Composting
Composting is a natural process involving microorganisms like bacteria that break down organic materials into nutrient-rich soil. It's essential for enriching gardens and contributing to environmental sustainability.
Basics of Composting
Composting is the controlled decomposition of organic materials, such as leaves, fruit and vegetable scraps, and yes, occasionally paper towels. It relies on the balance of nitrogen and carbon, which are essential components of this biological process. Nitrogen-rich materials, often green, provide proteins and enzymes necessary for microbe growth, while carbon-rich materials, typically brown, offer energy. Maintaining the right balance between these elements is crucial for efficient composting.
Nitrogen (green materials): includes grass clippings, vegetable scraps, coffee grounds
Carbon (brown materials): includes dry leaves, branches, shredded paper towels
Benefits of Composting
Composting offers multiple benefits to the environment and garden ecosystems. It recycles kitchen and yard waste, reducing the amount of garbage sent to landfills. This process results in the production of nutrient-rich soil that improves soil structure, moisture retention, and plant growth. Compost also introduces beneficial microorganisms to the soil, aiding plant health and resistance to disease.
Reduces landfill waste
Produces nutrient-rich soil amendments
Enhances soil structure and health
Supports beneficial bacteria and fungi
Composting Process
The composting process involves four key elements: microbes, oxygen, water, and temperature. The harmonious interaction of these elements leads to the breakdown of organic material. The microorganisms require oxygen to thrive, which is supplied by turning or aerating the compost regularly. Water is equally essential, as the microbes need the right moisture level to prosper. Finally, temperature plays a role in speeding up decomposition; a warmer heap will generally decompose materials faster.
Optimal conditions for decomposition:
Aeration: Regular turning adds oxygen
Moisture: Should be maintained at a level similar to a wrung-out sponge
Temperature: A hot compost pile can reach between 130-160°F
by ensuring these conditions are met, organic materials break down over time into a compost that can enhance soil and support the environment.
Types of Paper Towels
When considering the compostability of paper towels, it is crucial to distinguish between those that can be composted and those that cannot, often contingent upon their chemical treatments and ink content.
Compostable vs Non-Compostable Paper Towels
Compostable Paper Towels: These are typically made from biodegradable materials such as fibrous plant pulp, which includes recycled paper or bamboo. When unused or soiled with organic material, such as food residues, they can be broken down by microorganisms.
Unbleached Paper Towels: Often a brown color, they are free from chemical whiteners and are fully compostable.
Bleached Paper Towels: These can vary in compostability. While bleached with chlorine dioxide — a chemical also used to purify drinking water — not all bleaching processes impede compostability.
Non-Compostable Paper Towels: Some paper towels contain synthetic fibers or are heavily chemically treated, which may not break down easily or could introduce harmful substances into the compost.
Synthetic Fiber Towels: May not break down in a composting system.
Heavily Dyed Towels: Colors might indicate the presence of inks and dyes that are non-compostable.
Chemical Treatments and Ink
Chemicals and ink treatments on paper towels impact their suitability for composting.
Chlorine and Chlorine Dioxide: The use of these chemicals in the bleaching process is not universally detrimental to compostability. However, one must be cautious as some treatments might render the towels non-compostable.
Dyes and Inks: The presence of dyes and/or inks, particularly in decorative or printed paper towels, often makes them unsuitable for composting due to potential toxins.
Composting Paper Towels
Composting paper towels is generally feasible since they are made from organic materials that decompose. However, specific conditions and types of usage affect their suitability for composting.
Composting Used Paper Towels
Used paper towels that have not been in contact with greasy substances or harsh cleaning products can be added to compost. They serve as a carbon-rich material, or 'brown', balancing out the nitrogen-rich 'greens' like food scraps and yard waste. It's important to shred or tear the paper towels into smaller pieces to accelerate the composting process.
Suitable for composting:
Towel materials: 100% recycled, unbleached
Types of use: Water spills, vegetable drying, clean soil
Issues with Grease and Chemicals
Paper towels exposed to grease, oil, or butter should not be composted because these substances can attract pests and slow down the decomposition process. Similarly, if paper towels are used with cleaning products, they might contain harmful chemicals that could disrupt the compost ecosystem. These items are better disposed of in the trash.
Unsuitable for composting:
Towels used with: Greasy substances, synthetic cleaning agents
Potential issues: Pest attraction, compost contamination
Best Practices for Paper Towel Composting
Composting paper towels is a straightforward process, but it's important to distinguish between materials that can be included in the compost bin and those that should be left out to maintain a healthy composting balance between brown and green materials.
What to Include in Your Compost Bin
Brown Material:
Paper Towels: They are excellent sources of carbon and can be added to your compost as brown material. Ensure they are:
Made from 100% recycled material or biodegradable.
Free from chemical contaminants.
Additional Acceptable Browns:
Cardboard and napkins can also be included, given they're not coated with plastic or wax.
What Not to Compost
When it comes to composting, not all paper towels are suitable. Avoid composting paper towels that have been used to clean up:
Meat or dairy products, as they can attract pests and cause odors.
Greasy residue, which can interfere with the composting process and is not as readily broken down.
Animal waste, since this can introduce pathogens to your compost.
Not to Compost:
Paper towels labeled as antibacterial or those used with cleaning chemicals.
Products that have a shiny or plastic-like surface, as they probably contain materials that do not break down easily in a compost system.
Impacts on the Environment
Composting paper towels instead of disposing of them in landfills is a more sustainable and eco-friendly practice. When organic matter, such as paper towels soiled with food residues, is composted, it breaks down into carbon dioxide, water, and biomass, which enriches the soil without releasing significant amounts of methane—a potent greenhouse gas commonly generated in landfills due to anaerobic decomposition.
Recycling facilities may not accept paper towels because they can't be recycled once they are contaminated with food, grease, or chemicals. Composting paper towels, however, diverts them from the waste stream and reduces the environmental impact. It circumvents the problem of organic matter occupying landfill space, where its breakdown would otherwise contribute to methane emissions.
Here's a comparison of outcomes when composting paper towels versus sending them to a landfill:
Aspect Composting Paper Towels Sending to Landfill Methane Production Minimal or None High Carbon Dioxide Released during aerobic composting Released during aerobic and anaerobic breakdown Soil Health Enhances with nutrients and beneficial microorganisms No benefit Sustainability Promotes recycling of nutrients and responsible waste management Contributes to waste problem
Composting paper towels, particularly those made of eco-friendly materials, reduces the overall environmental impact by minimizing greenhouse gas emissions and supporting a recycling-oriented approach. This practice fosters a more responsible waste management system and aligns with sustainable living principles.
Alternative Solutions
When considering eco-friendly alternatives to composting paper towels, several sustainable options emerge. These solutions aim to reduce household waste and support environmental well-being.
Reusable Cloth Towels: One can utilize cloth towels made from recycled materials or sustainable fabrics. These towels can be washed and reused many times, significantly cutting down on paper waste.
Microfiber: Captures dirt and liquid effectively.

Table Comparing Alternatives:
Alternative Material Lifetime Compostability Cloth Towels Varies (cotton, bamboo, etc.) Multiple uses Reusable Biodegradable Towels Recycled Paper Single use Biodegradable Sponges/Scrubbies Plant Fibers/Recycled Plastic Multiple uses Depends on Material
In conclusion, by consciously selecting alternatives to traditional paper towels, individuals can positively impact the environment by reducing the amount of paper towel waste and embracing more sustainable practices.
Implementation in a Home Garden
In the context of a home garden, composting paper towels can be a simple yet effective way to produce nutrient-rich compost. Gardeners can add paper towels to their compost bins or piles as a carbon-rich material, which helps to balance the nitrogen found in food scraps and green waste. The process contributes to creating mulch that can later be used to enrich the garden soil.
When incorporating paper towels into a compost bin, it is important to ensure they have not been used with chemicals that could harm the composting process. Only add paper towels that are free from inks, dyes, or grease. Those used for mopping up water or organic materials are typically safe to compost.
The composting time for paper towels can vary, but they generally break down within two to six weeks. For optimal decomposition, shred or tear the paper towels into smaller pieces before adding them to the compost. This increases the surface area and accelerates their integration into the compost.
Recommended Composting Steps:
Check for Safety: Verify paper towels are free from harmful chemicals.
Prepare Material: Tear or shred paper towels.
Composting Ratio: Balance with appropriate green waste.
Monitor: Keep an eye on moisture level and turn pile regularly.
