The LunaRecycle Challenge, a $3 million competition by NASA, seeks innovative solutions to manage and recycle waste during long-term lunar missions. The goal is to reduce solid waste, improve sustainability, and minimize reliance on Earth-based supplies by creating closed-loop systems for waste management. Proposed solutions include autonomous robotic systems for waste sorting and processing, regolith-based material repurposing, water extraction from lunar ice, and organic waste conversion into resources like biogas. These approaches aim to address NASA’s requirements for mission self-sufficiency while inspiring advancements in terrestrial recycling technologies.
