The Permanent and Insatiable
The Permanent and Insatiable is a series of dissolving cityscapes made of PET (Polyethylene terephthalate) plastics inside a bioreactor tank. Throughout the exhibition, an enzymic reaction slowly degrades the plastic sculpture. Investigating the tension between seemingly indestructible materials such as plastics, and synthetic bioorganisms designed to consume them, Xin Liu imagines a world where metropolitan cities with an excess of manmade materials are confronted by the appetites of natural microbes.

“Materials science seems to operate within two mythic extremes…synthetic materials designed to be so resistant and indestructible that they verge on a kind of supernatural longevity and engineered biomaterials, such as enzymes or microbes, designed to consume precisely these sorts of super-resistant materials. … pulled back and forth between two supernatural ideals: there is that which resists to the point of uncanny permanence, of eerie immortality, and there is that which consumes to the point of universal insatiability, of boundless hunger.”

In 2018, Xin Liu initiated and led research project MicroPET: developing a modular bioreactor for a plastic degradation payload at the International Space Station (ISS). It is an autonomous payload for enzymatic reactions and microbial cultivation with fully programmable serial passaging and sample preservation, developed in collaboration with MIT Media Lab Space Exploration Initiative, the National Renewable Energy Laboratory (NREL), Weill Cornell Medicine, Harvard Medical School, and Seed Health. The team successfully conducted the payload experiment in the International Space Station in December 2022. The project is recognized as one of The Best Inventions of 2023 in TIME magazine and has been accepted into Nature Partner Journal Microgravity. The research work seeded the conceptual and technical development of The Permanent and Insatiable.

All PET plastic materials come from everyday urban necessities, including olive oil bottles, salad containers, shampoo bottles, and countless drink bottles. Materials used in the project were all contributed by members of Xin Liu Studio in London.
