Piss Spew Recycle • Full

From the sterile corridors of the International Space Station (ISS) to the most arid deserts on Earth, the ability to reclaim water from urine and emesis (piss and spew) is not just a feat of engineering; it is a necessity for the future of our species. 1. The Science of Urine Reclamation (Piss)

Researchers have engineered Saccharomyces boulardii (a type of yeast) to act like bone-forming cells. This "osteoyeast" accumulates calcium and phosphate from urine in its vacuoles and "spews" or secretes them as extracellular vesicles.

Liquid organic waste mixes, including stomach acids and partially digested organic carbon, present treatment challenges due to their low pH. However, industrial facilities can route these carbon-heavy streams into anaerobic digesters. Microorganisms break down the organic compounds to produce methane gas, converting a waste stream into renewable energy. Key Technologies Driving Biological Recycling piss spew recycle

If you are looking for ways to handle or "recycle" the nutrients or materials in a safe environment, consider these options: 1. Composting (Urine Only)

Before advanced purification begins, raw sewage undergoes standard municipal treatment. Heavy solids settle out, and mechanical screens filter out large debris. The remaining liquid enters biological reactors where billions of beneficial microbes consume organic matter, breaking down carbohydrates, fats, and human waste. Step 2: Microfiltration / Ultrafiltration From the sterile corridors of the International Space

Many dry cities now use recycled water. It provides a steady supply of water that never runs out. : Recycled water helps grow crops during droughts. Parks : Cities use it to water grass and trees.

Liquid waste, long considered useless and toxic. Microorganisms break down the organic compounds to produce

Urine represents less than 1% of total wastewater volume, yet it contains roughly 80% of the nitrogen and 50% of the phosphorus found in municipal sewage. These two elements are the primary ingredients in commercial fertilizers.

In the International Space Station (ISS), astronauts have been recycling urine into drinking water for over a decade. The Urine Processor Assembly (UPA) uses vacuum distillation: urine is boiled at low pressure (lowering the boiling point), water vapor is collected and condensed, while the brine residue is discarded. The distillate is then combined with other humidity condensate and passed through a series of filters and catalytic oxidizers. The result? Water cleaner than what most Earthlings drink.

: Wastewater treatment plants use advanced filtration, chlorination, and often UV light to strip out bacteria, chemicals, and solid waste.

: Some advanced cities mix treated water back into the drinking supply. Overcoming the "Yuck" Factor
