Effective waste management is critical for the sustainability of long-term space missions. This project proposes an innovative approach to upcycling polyethylene (PE) waste into valuable byproducts through an integration of thermal, chemical, and photodegradation methods using a centrifuge-based system. The process transforms PE into hydrocarbons and organic acids, which can be repurposed for synthesizing polymers, additives for fuel, and raw materials for bioplastics. This approach reduces dependence on Earth resupply missions, enhances resource efficiency, and addresses safety and sustainability challenges. The proposed methodology leverages chemical catalysts such as Platinum on Alumina and Strontium Titanate, enabling high-yield conversions under low-gravity conditions. By closing the loop on material reuse in space, this technology represents a significant advancement over traditional waste recycling methods.
