DIY drinkpee

Drinkpeedrinkpeedrinkpee is a project by Britta Riley and Rebecca Bray about the role our bodies play in larger ecosystems. It's an installation about the Urine to Fertilzer DIY Kit; Derive houseplant fertilizer and ocean-safe water from your pee!

"We all think of human pee as gross and something that ought to be vigorously “cleaned up” or sanitized. However, human urine is actually sterile (unlike faeces, urine is bacteria-free). This liquid by product of our daily lives can be a rich food source if it gets into the RIGHT part of the right ecosystem. Now, most human urine travels untreated into the waterways and is a significant cause of eutrophication, a toxic condition caused by harmful algae blooms, in the oceans. The excess Nitrogen and Phosphorus in our urine overfeeds algae (like Red Tide) and effectively suffocates fish. However, a pioneering biological waste treament process being used in Switzerland can extract this phosphorus & nitrogen for use as a fertilizer, leaving the rest of urine almost harmless to aquatic life. This kit gives users the opportunity to replicate the new technique at home and fertilize their plants with their own pee.

Users will test their urine before the reaction. Then, they will add an enzyme, wait for their urine to hydrolyse, and then add Magnesium Chloride. A sediment will build up at the bottom of the jar. Using a filter, they will pour off and flush the liquid, leaving the fertilzer in the jar. They can add water and the seeds included in the kit to grow their own watercress in the glass container used for the reaction."

Should men be able to give birth to children?

Koert van Mensvoort: Is the artificial womb frankenstein-like symbol of (male) engineers trying to steal the magical womb from women? Or… is it a feminist project and needed to reach through equality between the sexes? I personally lean towards the latter. To me it feels like progress if a girl can tell a guy to carry the womb for a change.
