How Human Waste Helps Mexican Farmers and the Environment | Global Ideas | DW


Artificial fertilizers are banned on Tomas Villanueva’s farm in the small town of Tepetixtla on Mexico’s west coast. All products are fertilized with homemade human manure. He says poo and pee have a bad image, but the composting process means it’s hygienic – and better for the soil and biodiversity.

Agricultural runoff from artificial fertilizers harms soil and insects and pollutes water in Mexico, so some farmers, like Villanueva, are turning to composted human feces and urine to feed crops with the nutrients they need. need. The process also saves water and reduces pollution because excrement is not discharged into sewers. Much of the country’s raw sewage flows directly into rivers, lakes and the sea.
