virtsankeruulla
Virtsankeruulla is a term used in speculative biology and science fiction to denote a concept for a waste-processing unit that recycles urine into usable nutrients within closed ecological systems. The concept can refer to either a living microbial consortium designed to metabolize urea and related compounds, or a bio-hybrid device that combines biological processes with engineered machinery. The term is fictional and used primarily in world-building and theoretical discussions about life-support systems.
Etymology and usage: The name is a constructed compound drawing on Finnish roots such as virtsa (urine)
Concept and design: In biological variants, virtsankeruulla envisions a coordinated microbial community that converts urea into
In fiction and theory: The virtsankeruulla unit is often depicted as a modular component of space habitats,
