The document describes a device called the Guldkannan Towa, which is part chamber pot and part watering can. It is designed to collect human urine, which can then be diluted and used as a natural fertilizer for gardens. Urine contains nitrogen that is similar in composition to commercial fertilizers. The durable plastic Guldkannan Towa can hold up to 10 liters of "liquid gold" urine and keep odors contained. When the urine is diluted and applied to soil, garden yields are reported to be up to seven times higher than without fertilizer. The device sells for 595 SEK including VAT and is available in Europe.
