A surprising answer.
The way we handle toilet paper after use is not just a daily habit—it also reflects personal hygiene awareness, environmental protection, and the efficiency of our drainage systems. Although it may sound simple, the question “Should toilet paper be thrown into the toilet or the trash bin?” has sparked much debate because it involves many aspects to consider.

So, what is the correct action? In reality, the answer depends not only on the type of toilet paper used but also on the condition of the drainage system and the cultural practices of each area and household. These choices can affect our living environment, from preventing clogged pipes to reducing waste.

Should toilet paper go into the trash bin or the toilet? A simple act, but not everyone does it correctly.

That’s why it should be carefully considered, based on three factors:

1. Type of toilet paper

The type of toilet paper can significantly affect how it should be disposed of. Currently, there are many types on the market, from regular toilet paper to biodegradable paper. Regular toilet paper often does not dissolve quickly in water and may cause blockages if flushed down the toilet.

In contrast, biodegradable toilet paper is designed to break down easily in water, reducing the risk of clogs. This means that if you use biodegradable paper, flushing it may be a more reasonable option. However, if the paper is unsuitable, disposing of it in the trash bin is the safer choice.

To test dissolvability, you can try a simple experiment: put a sheet of toilet paper in a bowl of water and stir it with chopsticks. If it breaks apart into small pieces, it dissolves well. In that case, you can safely flush it without worrying about blockages.

2. Drainage system

The condition of the drainage system in your area also plays an important role. In places with modern and well-maintained systems, flushing toilet paper usually doesn’t cause major issues.

However, in areas with outdated or poorly maintained systems, flushing paper may result in serious clogs. These problems not only disrupt daily life but also incur costly repairs for the community. Therefore, understanding your local drainage system is essential before deciding.

3. Cultural habits

Cultural habits are another factor. In many countries, especially Western nations like the U.S. and most of Europe, flushing toilet paper is common and even encouraged. Their drainage and wastewater systems are designed to handle toilet paper effectively.

However, in other places, including Vietnam, throwing toilet paper into the trash bin is more common—often because drainage systems are weaker and prone to clogging.

So, should toilet paper be flushed or thrown in the trash?
The answer depends on several factors already discussed. If you use toilet paper that dissolves well and live in an area with a drainage system designed to handle it, flushing is convenient and reasonable. On the other hand, if you live somewhere with poor drainage or use paper that doesn’t break down easily, disposing of it in the trash is the safer choice—helping to prevent clogs and ensuring hygiene for your household.

Consider your specific situation and the information shared above to make the right decision—not only for yourself but also for the safety and health of the community.
