Submersible Design

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. Pioneering biological waste treatment processes can extract this phosphorus and nitrogen for use as a fertilizer, leaving the rest of urine almost harmless to aquatic life. Submersible Design’s kit gives users the opportunity to replicate the new technique at home and fertilize their plants with their own pee.

DrinkPee is a project by Rebecca Bray and Britta Riley.
