Viitorul hranei în spațiu: sticlele PET ar putea fi transformate în proteine și grăsimi comestibile

Researchers have developed a method to convert plastic waste into food for astronauts using genetically modified yeast. This project, funded by NASA, aims to address food supply challenges for long-duration space missions. The process involves breaking down PET plastic into smaller carbon-rich molecules, which are then transformed into proteins and fats by yeast. The resulting mixture can be 3D printed into biscuit-like discs. While the production cost is currently high, researchers believe it could decrease with improved efficiency. This technology may also have applications on Earth in isolated environments, addressing both plastic waste and food demand issues. However, public acceptance remains a significant challenge.
