What happens to the food we digest after it leaves our bodies? Is it waste to be discarded or a resource to be reused? Looking for answers, director Rubén Abruña embarks on an investigative and entertaining quest through 16 cities across 4 continents. He follows the poop trail from the long Parisian sewers to a huge wastewater treatment plant in Chicago. The presumed solution, adopted around the world, to use the semi-solid remains of the wastewater treatment process as a fertilizer, proves to be a living nightmare, because they contain heavy metals and toxic PFAS chemicals. Can excreta be used to grow food and ease the imminent fertilizer scarcity?
Following the screening: Discussion with director Rubén Abruña and Andreas Doerne (Holistic Compost Lab) + presentation of the book „Holy Shit“ by publisher Undine Löhfelm.
