NETHERLANDS SHOWS URINALS TURN PEE INTO FERTILZER FOR LOCAL FOOD
Amsterdam's urine alone can fertilize 10,000 football fields' worth of plants.
Drink some water, quick!Peeing in public isn’t usually a government-sanctioned
activity. But a few weeks ago, Dutch officials lined up some
not-so-private urinals in an Amsterdam park and invited local men to
come and, well, partake. It was all in the name of the environment:
Instead of sending urine straight down drains, the local water district
wants to turn it into fertilizer for local farms.
Phosphorus extracted from the temporary park urinals will go to a
green roof in the city. And today, the water utility will launch a new
recovery plant designed to mine the phosphorus out of all of the
wastewater in the region. Amsterdam's pee alone can fertilize 10,000
football fields' worth of plants, according to officials.
The idea all began because the phosphorus from urine was causing
problems--it forms crystals, which were clogging local pipes. "We
thought, if we have to remove it, why not do it in a proper way," said
Peer Roojimans, who serves on the board of the water authority.
"Phosphorus is needed for survival for everything in life, but it’s a
limited product, and the mines are exhausted. Since everyone takes it
with us every day--and supplies it to our sewage treatment plant when we
go to the toilet--we wanted to develop a device that could reuse it."
After wastewater goes to the new recovery plant, the phosphorus and
nitrogen from the urine will be separated, cleaned, and transformed into
struvite, a slow-release fertilizer. New Dutch laws allow it to
officially be used on farms starting on January 1.
it seem that poo has been left out of the plan, Roojimans points out
that the entire wastewater treatment plant for the Amsterdam area--which
serves a million people--runs entirely on electricity that is produced
from solid waste.
