The Cubie can be emptied into an above-ground barrel or a buried tank for storage, and pumped out as needed for use as fertilizer., or be periodically pumped out and removed by a certified hauler.
Urine as Fertilizer
The urine of one person contains about 10lbs of nitrogen, 1 pound of phosphorus, and 2 pounds of potassium, enough to fertilize 4000-5000 sq.ft. of gardens, lawns, shrubs, or trees, or grow enough wheat to make 365 loaves of bread.
Urine diversion is the most affordable solution for managing nitrogen and phosphorus to reduce water pollution. Urine diversion cost only 1/10 as much as conventional solutions such sewers and Innovative and Alternative (I/A) septic systems. Compositng toilets and urine diversion qualifies as an I/A approach in the MassDEP regulatory framework.
