If you are one who believes that some of the best things in life are free, then the Towa by Swedish startup Guldkannan is for you.

The Towa is a device to help gardeners around the world put the nitrogen-rich power of urine to work in their gardens. Instead of flushing away what some believe to be the world’s best, and certainly completely natural and free fertilizer, one can simply deposit their “liquid gold” into the Towa, then use it to water the garden.

The ergonomically designed combination chamber pot and watering can hold 10 liters, is easy to carry, and comfortable to sit on. Made of recyclable and durable Polypropylene, the can will withstand weight up to 150 kilos (about 330 pounds) and seals tightly to contain the urine, protecting the nitrogen and preventing odor.

Gardeners need only dilute the urine with water and apply it to their soil for yields, according to Guldkannan, as much as seven times higher than would be achieved without fertilizer. Although the Towa is not available in the US, gardeners interested in using their own natural fertilizer can certainly do so: be creative.

If you really get into the idea, next June 21 you can participate in Pee on Earth Day when people all over the world are encouraged to “Peecycle.”
