Institute of Civil Engineers: From Haiti to Mars: a Giant Leap for Human Waste
US non-government organisation Sustainable Organic Integrated Livelihoods (SOIL) has developed a thermophilic composting system for human waste in Haiti, where only a quarter of the population has access to proper sanitation.
The resulting compost is both safe to handle and rich in nutrients – potentially enough to grow the same amount of food previously eaten.
Sanders concludes, ‘The engineering community must accept that use of inorganic fertilisers is unsustainable, while also recognising the huge potential that human waste has to play in the recirculation of nutrients throughout the environment.’ Certainly life on Mars will not be possible without it.”
