ESL Upper-Intermediate Lesson Plan - Uses of Urine

Reading Comprehension


Have you ever contemplated the value of your own pee? With over 7 billion inhabitants on planet earth, we are producing an average of 10.5 billion litres of waste a day. What if we could use our pee to benefit the world instead? In fact, scientists in Bristol university have already proven that that they can power a smart phone using urine. And more and more subsistence organic growers in the US and Europe are turning to human urine as an effective fertiliser. But using pee in our every day lives is not a new concept, let's have a look at how it helped us to progress scientifically and industrially in the past.

Urine and the Fashion Industry

The ancient Romans used to collect urine from public urinals where it was used to remove tough stains from clothes. Dirty clothes would be placed in a vat of pee and mixed with water. A worker would get into the tub and stomp on the clothes to beat the dirt out, much like a modern day washing machine. Business was so good that merchants involved in the collection of urine had to pay a pee tax to Emperor Vespasian. Apparently, when his son complained that it was a disgusting idea, he supposedly retorted “Money doesn't stink”.

Keep Your Whites White and Your Colours Bright

Urine is a rich source of urea. If left to decay, urea becomes ammonia. In the past ammonia was used to soften and tan animal hides. Soaking the skins in urine also helped to remove hair and bits of flesh. Urine was of great importance in the 16th century UK, where clothes were made from mainly wool, flax or silk. The dyes they used to colour the cloth were made from natural ingredients such as berries, flowers, leaves and roots. So they needed a mordant - an agent that binds the colour to the material. Urine was an excellent mordant and many families made and dyed their own clothes with their own urine.

Killer Pee

Gunpowder's main ingredient is potassium nitrate. Before it was mass-produced in factories in the 20th century, people used the naturally occurring nitrogen from pee to make it. According to a DIY gunpowder instruction manual, written by physician and geologist Joseph LeConte, you needed to mix leaves, ash and straw with manure. Every week you would add human and animal waste to the pit. The concoction was stirred regularly and after a few months nitre would appear at the surface as a white salt.

Urine was also used in another unusual wartime situation. During World War 1, soldiers were advised to soak a cloth in pee and cover their noses with it, thereby diminishing the effects of a chlorine gas attack.

Urotherapy and Home Remedies

Urotherapy is the practice of drinking, massaging or bathing in your own urine. Proponents claim that urine has anti-bacterial, anti-viral and anti-fungal properties. Opponents to this therapy deny there are any benefits to drinking ones own urine and indeed may even cause harm. In spite of its unappealing origins, pee is a popular home remedy in the treatment of athletes foot and acne. Because urine is so sterile, it can even be used to wash out a wound (if you do not trust the local water supply). Some baseball players have even admitted to urinating on their hands as a preventative measure against blisters. Other uses include the treatment of: insect bites, arthritis, diabetes, rabies, tuberculosis, cancers, heart disease, digestive disorders, prostate problems, malaria, asthma, colds, flu, burns, skin disorders...etc.

Only a couple of hundred years ago it had a very useful purpose for clothes – it protected them from insects. Robes were kept near a chamber pot under the bed and the strong smelling ammonia emanating from the pee killed the moths before they destroyed the garments. And last, but not least, urine helped to give our ancestors a gleaming smile. Before the invention of toothpaste, people used it to brighten and whiten up their teeth.
