worldwide ecological sanitation projects in 2007
Capturing and reusing nutrients from wastewater and excreta can potentially replace 20–100 % of current chemical fertilizer use depending on the country [60], decrease carbon dioxide emissions from wastewater treatment plants (Jönsson 2019), and ameliorate problems of eutrophication [34].

Acceptance of human excreta derived fertilizers in Swedish grocery stores

Diverter ridge sticks up high enough to touch your butt. Urine side is too flat; if you pee too quickly it will wash over into the poop bucket. Fecal opening is too oblong; does not fit a standard 5 gallon bucket. Urine drain is metric and does not fit American plumbing sizes.
This one here is smooth plastic that is easy to clean. Also this design has a lip at the edge of the separator that extends down into the bucket, so any liquid that hits the edge goes straight into the bucket instead of down the underside of the funnel and down the outside of your tube and onto the floor. The drain hole is bigger which forced me to upgrade from a waterhose that kept getting clogged anyway.
I purchased vinyl tubing with 1 1/4” inner diameter and it fit exactly. This item does fit on a 5 gallon bucket. I’m in the process of building a wooden box to attach to a regular round toilet seat.
Most soil bacteria prefer well-oxygenated soils and are called aerobic bacteria and use the oxygen to decompose most carbon compounds.
According to a Swedish study, every 1,000 liters (264 gal.) of urine contains 600 g (.66 lbs) apiece of phosphorous and potassium and 900 g (1 lb.) of sulphur. Combining both solid and liquid waste, a single human produces 4.5 kg (9.9 lbs) of nitrogen per year, according to the World Health Organization.
Reverend Henry Moule’s invention of the earth closet in 1860.2,3The most basic version of the earth closet was a seat above a bucket filled with “fine dry earth, charcoal, or ashes.” Pulling a handle caused fresh earth to fall into the bucket from above. More elaborate versions included closets on adjacent floors, connected via a chute in the wall.3
