Lunar micturition comes with unexpected benefits.
The role human excretions play on earth has recently preoccupied an American-based research team. More specifically, the biochar made from solid human excrement, which has proved ideal as fertiliser once microplastics and chemicals have been removed from it.
Mixing the biochar with nutrients from urine could provide 15% of the phosphorus needed to produce crops. For nitrogen and potassium, the figures rise to 17% and 25% respectively. Proportions that can be adjusted to comply with individual needs of crops.
The process could significantly reduce transport costs and emissions associated with disposing excrement, as biochar itself weighs a fraction of solid faeces.
Coated bacteria can also support agriculture, while penguin faeces influence the atmospheric conditions.
