Compost n.3 is the third episode of Compost series. An artistic project that combine science, video art and digital sculpting and is ispirated by the recent studies of Donna Haraway on the concept of Chtulucene: not a post human world but a human compost world characterized by a continuous process of composition and decomposition. In Compost n.3 a female body navigating in a liquid landscape infiltrated by technology becomes the lifeblood of a possible regeneration for a hybrid human/non-human being, the only hope for a now damaged planet. A world in which each new configuration of matter carries with it the remnants of the previous configurations. This process of transformation and renewal questions the very role of the individual and reconnects both to Western and Eastern myths of birth and to the mysteries of the chthonic world to experience a metamorphic process in continuous evolution after the ecological catastrophe.
