MIT’s CERBERUZ Team Secures Dual Victory in NASA LunaRecycle Challenge
In a breakthrough that could reshape the economics of lunar habitation, a student-led team from the Massachusetts Institute of Technology has taken first place in both the Prototype and Digital Twin tracks of NASA’s LunaRecycle Challenge. The competition, part of NASA’s Centennial Challenges series, asked innovators to devise ways to reuse, recycle, or up-cycle waste generated on long-duration missions to the Moon. MIT’s Composites for Extraterrestrial Recycling By Engineering the Reuse and Upcycling of Zotek (CERBERUZ) team delivered a system that converts otherwise unusable packaging and other debris into a composite feedstock suitable for on-site manufacturing of spare parts and tools.
The MIT team’s dual win demonstrates a viable pathway for turning lunar trash into valuable resources, potentially reducing the need for costly resupply missions from Earth and offering a template for sustainable material cycles on future off-world outposts.
From Waste to Workhorse: How CERBERUZ Turns Trash into Tools
The CERBERUZ approach is built around a compact injection-molding machine affectionately named PERSEPHONE. The system first separates incoming non-biological waste into two streams: thermoplastics and everything else. All material is then ground into a fine powder, blended, and loaded into the injection molder. Within the heated barrel, the thermoplastics melt while the remaining particles—most notably fragments of Zotek F30, a closed-cell thermoset foam used for aerospace packaging—remain suspended as reinforcing filler. The resulting molten mixture is injected into precision molds, producing high-quality composite parts that can be replicated quickly and reliably.
Zotek F30 presented a particular challenge because, as a lightweight thermoset foam, it has no established recycling pathway on Earth. The CERBERUZ team’s insight was to treat the foam not as waste but as a structural additive, enhancing the mechanical properties of the final composite. As graduate student José Soto, the pre-processing lead, explained, “We had big shipments of Zotek coming in, and one person can carry them on their head like it’s nothing. The box is the size of a person.” By incorporating this abundant, low-mass material into the feedstock, the team maximizes the usable mass derived from each shipment.
Crucially, the entire process relies solely on mechanical operations powered by electricity. It avoids water-intensive methods, chemical depolymerization, and the generation of secondary chemical waste. This design philosophy aligns with the harsh constraints of a lunar environment, where water is scarce and any introduced chemicals could pose contamination risks.
Digital Twin: DEIMOS Predicts Performance Before Production
Complementing the physical hardware, the team developed a digital twin called DEIMOS (Digital Environment for Intelligent Modeling of Operational Systems). Using data harvested from real production runs, DEIMOS simulates how different blends of recycled material and part geometries will behave during molding. The model predicts critical outcomes such as mold fill, warpage, and shrinkage risk, allowing astronauts to evaluate the feasibility of a part before committing limited resources to its fabrication.
This predictive capability is especially valuable on the Moon, where material, energy, and time are at a premium. By running virtual trials, crews can prioritize the most promising designs, reducing the likelihood of failed prints or wasted feedstock.
Team Structure and Institutional Support
The CERBERUZ effort grew out of the MIT Space Resources Workshop, a co-curricular initiative founded in 2017 that brings together students passionate about building systems for lunar and Martian exploration. The team blends expertise from four MIT departments—Aeronautics and Astronautics, Mechanical Engineering, Electrical Engineering and Computer Science, and Materials Science and Engineering. Faculty advisors include former NASA astronaut Professor Jeffrey Hoffman and research scientist George Lordos, who also serves as the lead advisor.
According to MIT News, “What impresses me most about this team is the quality of leadership,” Lordos said, highlighting team lead Lanie McKinney and co-leads Palak Patel (manufacturing and materials characterization), Lilly Etzenbach (digital twin), and José Soto (pre-processing). Their coordinated effort allowed the project to progress from a Phase 1 selection in 2025 through Phase 2 milestones, culminating in a final demonstration in the summer of 2026.
Implications for Lunar Sustainability and Earth-Side Applications
The dual victory in NASA’s LunaRecycle Challenge signals that closed-loop material cycles are moving from concept to demonstrable technology. By converting packaging and other waste into a feedstock for additive or subtractive manufacturing, future lunar habitats could drastically cut the mass of supplies that must be launched from Earth—a factor that directly influences mission cost and feasibility.
Beyond the Moon, the CERBERUZ methodology offers a template for waste reduction in remote or resource-constrained environments on Earth. The reliance on mechanical processes, the avoidance of water and chemicals, and the use of a digital twin for process optimization could be adapted for offshore platforms, disaster-relief camps, or isolated research stations where logistics mirror the challenges of space.
- Mechanical recycling eliminates the need for water-intensive or chemical-heavy processes.
- Digital twin integration enables predictive manufacturing, reducing trial-and-error.
- Use of Zotek F30 transforms a problematic foam into a reinforcing filler, increasing material efficiency.
- Cross-disciplinary collaboration leverages expertise from aeronautics, mechanical, electrical, and materials engineering.
- Financial backing includes $925,000 in prize money, earmarked for further development through the Space Resources Works initiative.
Funding, Milestones, and Future Directions
The LunaRecycle Challenge awarded the CERBERUZ team a total of $925,000 in prize money across its two winning tracks. The team intends to reinvest these funds into the Space Resources Works program, a continuation of the MIT Space Resources Workshop’s mission to develop practical technologies for extraterrestrial resource utilization.
While the system has been demonstrated successfully in a terrestrial test environment, the next logical step is a field trial in a simulated lunar habitat. Such a test would evaluate the system’s performance under reduced gravity, limited power, and the radiation environment expected on the Moon. The digital twin, DEIMOS, would be a critical tool in adapting the process parameters to those conditions.
Broader Context: Recycling in the Fourth Industrial Revolution
The CERBERUZ achievement sits at the intersection of several Fourth Industrial Revolution (4IR) trends: advanced manufacturing, digital twins, and sustainable resource cycles. By integrating a physical recycling line with a data-driven simulation environment, the team exemplifies how Industry 4.0 principles can be extended beyond Earth-bound factories to off-world outposts.
Moreover, the project underscores the role of generative AI and machine learning in optimizing material blends and predicting manufacturing outcomes. While the source material does not detail specific AI algorithms, the existence of a digital twin suggests that data analytics and predictive modeling are already being leveraged to enhance system reliability—a hallmark of smart manufacturing in the 4IR era.
