Can you flush paper towels? No, you should not flush paper towels. Paper towels are a staple in our daily lives, offering convenience for cleaning and drying tasks. However, many people mistakenly dispose of paper towels by flushing them down the toilet, leading to significant plumbing and environmental issues. This article explores why paper towels are not water-soluble, why they should never be flushed, and the differences between paper towels and other paper products.

What is Non-Solubility in Paper Towels?

Paper towels are designed to be highly absorbent and durable. Their non-solubility means that they do not break down or dissolve in water, unlike toilet paper, which is specifically engineered to disintegrate when exposed to water, making it safe for flushing. The key difference lies in their composition and the presence of wet strength agents used in the manufacturing process.

The Impact of Non-Solubility

  •  Impact on Household Plumbing Flushing paper towels can lead to severe blockages in household plumbing systems. Unlike toilet paper, which dissolves and passes through pipes easily, paper towels remain intact, causing clogs that can be expensive to repair.
  • Impact on Municipal Sewer Systems On a larger scale, paper towels can cause significant problems in municipal sewer systems. Blockages can lead to sewer overflows and increased maintenance costs, impacting public infrastructure and the environment.

Testing Paper Towel Non-Solubility

To understand the non-solubility of paper towels, various absorbency experiments can be conducted. These experiments demonstrate how paper towels absorb water but do not dissolve, showcasing their durability and strength.

  1. Absorbency Tests

By conducting absorbency experiments, one can observe which paper towel brand is more absorbent and how much water is absorbed by a paper towel. The most absorbent paper towels will soak up water efficiently, but their structure remains intact, highlighting their non-soluble nature.

      2. Interpreting Results

The results of these experiments reinforce the need to dispose of paper towels properly, as their robust construction prevents them from breaking down in water.

Comparing Paper Towels to Other Paper Products

  • Toilet Paper

Toilet paper is designed to be water-soluble and safe for flushing. It breaks down quickly in water, preventing clogs in plumbing systems.

  • Facial Tissues, Paper Towels, Wet Wipes, Handkerchiefs, and Napkins

These products are not water-soluble and should not be flushed. They are manufactured to be durable and absorbent, making them ideal for their intended uses but unsuitable for disposal via toilets.

  • Recent Developments

In recent years, water-soluble wet wipes have appeared on the market. These wipes dissolve in water but are also more prone to tearing. Achieving both durability and solubility in paper products remains challenging. Therefore, it is crucial to check if a product is flushable before disposing of it in the toilet.

The Role of Wet Strength Agents in Papermaking

Wet strength agents are crucial in the papermaking process, particularly for products like paper towels that need to retain strength when wet. These agents increase the paper's resistance to disintegration when exposed to water. The amount of wet strength agent used can significantly impact the quality of the paper towel. For instance, paper towels require a higher dose to ensure they don't fall apart when wet, contributing to their high absorbency and non-solubility. This is why the most absorbent paper towels, which are excellent at absorbing water, should not be flushed as they do not dissolve like toilet paper.

Proper Disposal of Paper Towels

  • Household Waste Management

Always dispose of paper towels in the trash rather than flushing them. This prevents plumbing issues and contributes to better waste management practices.

  • Commercial and Public Spaces

Ensure that clear disposal instructions are provided in commercial and public restrooms. Use designated bins for paper towel disposal to prevent clogs and maintain hygiene.

  • Recommendation for Public Restrooms

In settings where proper disposal is harder to manage, such as kindergartens and schools, it is advisable to use pull-out toilet paper for hand drying. This type of toilet paper, even if accidentally flushed, will not cause blockages.

Educating Consumers

Consumer education is vital in promoting proper disposal habits. Clear labeling on packaging and public awareness campaigns can help inform people about the differences between water-soluble and non-soluble paper products and the importance of correct disposal methods.


Understanding the non-solubility of paper towels and their proper disposal is crucial for maintaining plumbing systems and protecting the environment. By educating consumers and promoting responsible disposal practices, we can reduce the occurrence of clogs and support sustainable waste management.
