How to Recycle Urine [5 Ways]

Every time you visit the restroom, valuable chemicals flush down with your urine. The human body produces nitrogen and phosphorus – vital nutrients for plant growth – in its urine!

Recently, researchers from Finland have discovered a way to extract them efficiently and profitably.

Urine is mostly water but contains urea, the chemical form of nitrogen that our bodies have removed as waste.

Additionally, you can extract excess phosphorus from this natural resource to be used again instead of being thrown out with the wastewater!

We will show you the ways to recycle urine safely.

Ways to Recycle Urine

1. Urine can be Recycled and Used as a Fertilizer

For generations, farmers and gardeners have used urine as a natural fertilizer for their crops and plants.

Modern technology has allowed us to take this ancient practice to a new level; we can now recycle and purify urine as an efficient form of nutrient-rich fertilizer.

Not only is the product non-toxic with minimal environmental impact, but it has also been proven to give gardens and greenery superior results while reducing overall water consumption.

Urine recycling is no longer something in science fiction – it’s a reality that even the most amateur gardeners can succeed.

2. Collect Urine in a Clean Container

Collecting urine in a clean container is an important step in many medical tests. Some of the most common samples requested include: testing for pregnancy, monitoring kidney function, and checking the levels of certain minerals in the body.

No matter your sample’s purpose, gather it properly and store it in a secure place away from any potential contaminants, like dirt or bacteria.

Carefully pour your collected urine into a sterile container and store it in a cool spot away from direct sunlight until you bring it to your doctor or laboratory.

Collecting and storing urine properly allows doctors to accurately interpret test results and provide tailored medical treatment for each individual.

Remember to label the container with your name and date so healthcare professionals can ensure that they have the correct sample for testing.

3. Dilute the Urine with Water

Diluting the urine with water can be a beneficial tactic to flush out any unwanted compounds in the body, such as drugs.

Not only is this approach helpful for decreasing detectable levels of certain substances, but it also helps reduce the concentration of metabolites eliminated in your urine.

It’s important to note that you should use this practice sparingly and under the guidance of a doctor, as drinking excessive amounts of water is not always recommended–it could even be dangerous in some cases.

Diluting urine with water can be an excellent way of cleansing your system, but it’s wise to seek professional advice first.

4. Use Diluted Urine on your Plants or Garden

Urine can be an effective way to nurture your plants and garden. Diluting it with water is key – when used in 10-20 parts water to 1 part urine, you create a nutrient-rich liquid fertilizer that your plants will love!

Urine is packed with nitrogen, phosphorus, and potassium, all essential for healthy plant growth, yet most flush it away.

Give yourself a chance to conveniently support the health of your garden simply by collecting and diluting pee before applying it directly to your outdoor green spaces.

You can join countless other eco-friendly homeowners who use their urine as a fertilizer to reduce waste and give back to the environment.

5. Urine Can also be Used to Clean Surfaces

Urine is a product of the body and is generally thought of as waste and something we want to get rid of, but believe it or not, it has many uses!

Urine can clean surfaces, such as bathrooms or kitchen counters. This method has been used for centuries in certain parts of the world. 

It’s an effective disinfectant that is natural and eco-friendly. It can also be used in place of expensive cleaning products, so you’ll save money and help keep your environment cleaner at the same time.

With a little bit of elbow grease, you’ll have a perfectly shiny surface without harsh chemicals.

Be Sure to Wash Your Hands After Handling Urine

One important habit to maintain for good health is washing your hands thoroughly after handling urine. We often forget that urine contains bacteria, which can transfer to our hands.

Unless we wash them properly afterward, those same bacteria can get into the body through cuts or other electrical pathways. 

Proper hand washing will help reduce the chance of getting a bacterial or viral infection from coming into contact with someone’s urine.

Therefore, pay attention to this simple but effective way of protecting your health and safety: always wash your hands after handling urine.

Can We Recycle Urine on a Large Scale?

Yes, urine can be recycled on a large scale. Several cities and organizations worldwide are already implementing successful urine recycling programs.

One example is a long-standing urine recycling program that collects urine from public toilets and transports it to treatment facilities where it is converted into fertilizers for agricultural use. The program has been successful in reducing the amount of nitrogen and phosphorus in wastewater, which can cause environmental problems.

Similarly, another project aims to collect urine from public toilets and convert it into fertilizers for agricultural use. The project is expected to collect and treat a large amount of urine per year, which will reduce the amount of nitrogen and phosphorus in wastewater and provide a sustainable source of fertilizer for farmers.

In addition, several organizations and companies are working on large-scale urine recycling projects, which can provide significant environmental benefits such as reducing waste and pollution, conserving water resources, and providing a sustainable source of nutrients for agriculture.

Benefits of Recycling Urine Safely

Recycling urine safely can provide several benefits for the environment and human health. Here are some of the key benefits:

  • Reducing Water Usage: Recycling urine can reduce the amount of freshwater used in agriculture, as it provides a sustainable source of plant nutrients. This can help to conserve water resources, particularly in areas where water scarcity is a concern.
  • Reducing Wastewater Pollution: Urine contains high nutrients such as nitrogen and phosphorus, which can cause eutrophication in water bodies if not properly treated. Recycling urine safely can prevent these nutrients from entering water bodies and causing environmental problems.
  • Providing a Sustainable Fertilizer Source: Recycling urine can provide a sustainable source of fertilizer for agriculture, reducing the need for synthetic fertilizers that can have negative environmental impacts. Additionally, urine-based fertilizers are effective in improving crop yields and soil quality.
  • Improving Soil Health: Urine-based fertilizers contain organic matter, which can help to improve soil health and increase soil carbon sequestration. This can help to mitigate climate change by reducing greenhouse gas emissions.
  • Saving Energy: Recycling urine can also save energy by reducing the need for energy-intensive wastewater treatment processes.

Overall, safely recycling urine can provide a range of environmental and agricultural benefits, as well as contribute to sustainable development and reduce human activities impact on the environment.

The Bottom Line

Urine can be recycled and used in various ways, such as fertilizer, a cleaning solution, and even for medical testing. Collect it properly in a clean container and dilute it with water to reduce the concentration of any unwanted compounds or bacteria before use or disposal.

Be sure to wash your hands afterward for maximum hygiene and safety! Recycling urine is a great way to reduce waste and give back to the environment.

Giving urine another chance is beneficial not only for the environment but also for our health. So next time you flush, consider recycling your urine!


What can be made from urine?

Almost all of the nitrogen found in urine is contained within urea, a chemical that has become one of the most popularly used forms of nitrogen fertilizer worldwide.

How long is urine Good left?

It is important to keep your urine sample cold and refrigerated at all times to ensure accuracy.

Bacteria in the urine will multiply if not stored properly, so discard any samples older than 24 hours.

How is urine recycled in space?

Through the use of a distillation assembly, urine is heated and boiled, and the resulting vapor is processed through a water filtration system. Chemical purification is applied to the water until it reaches a state that is safe for use by the crew.

This process has the benefit of reducing costs associated with transporting water to the station from Earth, which can be heavy and expensive.

Does urine remove waste?

The human body eliminates toxins and waste materials through urine, using the urinary system as a filtering mechanism. The process involves a network of tubes and ducts that are interconnected with the digestive system and blood vessels.

By removing these waste materials, the urinary system contributes to the overall functioning of the body, ensuring that it operates effectively.
