Why MIT’s CERBERUZ team’s win matters for lunar sustainability
MIT’s Composites for Extraterrestrial Recycling By Engineering the Reuse and Upcycling of Zotek (CERBERUZ) team captured first-place honors in both the Prototype and Digital Twin tracks of NASA’s LunaRecycle Challenge. Their system transforms packaging waste and other non-biological debris into composite feedstock that can be injection-molded into spare parts and tools directly on a lunar outpost, dramatically cutting the need for costly resupply missions.
According to MIT News, the CERBERUZ team’s approach—an injection molder nicknamed PERSEPHONE combined with a digital twin called DEIMOS—grinds, melts, and molds lunar trash into high-quality components, offering a practical pathway to on-site manufacturing that could keep future moon habitats free of bulky landfills.
Background: the LunaRecycle Challenge and the lunar waste problem
Establishing a permanent human presence on the Moon demands sophisticated spacecraft, habitats, life-support systems, and a constant flow of supplies from Earth. Every shipment brings packaging, insulation foams, and other disposable items that, without a recycling strategy, would accumulate into “mountains of waste.” Shipping spare parts and tools from Earth is astronomically expensive, so NASA’s Centennial Challenges series introduced LunaRecycle to spur solutions that could reuse, recycle, or upcycle space waste for longer-duration missions.
The challenge explicitly encouraged concepts that could also have terrestrial applications, reflecting the broader 4IR goal of turning waste streams into valuable resources. The CERBERUZ team answered this call by designing a closed-loop system that operates without water or hazardous chemicals—critical constraints for an environment where every kilogram and every watt of power is precious.
How the CERBERUZ system works
The core of the solution is an injection-molding machine called PERSEPHONE. The process unfolds in three stages:
- Separation: Non-biological waste is sorted into two streams—thermoplastics and everything else.
- Grinding and mixing: All materials are pulverized into a fine powder, then combined. The mixture is loaded into PERSEPHONE where thermoplastics melt, suspending the remaining particles in the molten plastic.
- Molding: The composite feedstock is injected into custom molds, producing parts ranging from simple brackets to more complex tools.
A particularly stubborn component of lunar waste is Zotek F30, a closed-cell thermoset foam used for aerospace packaging. Zotek cannot be recycled by conventional means because it is a thermoset, not a thermoplastic. The CERBERUZ team ingeniously repurposes Zotek as a reinforcing filler within the molten feedstock, turning a lightweight, otherwise unusable material into a structural advantage.
Because the system relies solely on mechanical processes powered by electricity, it avoids water-intensive steps and eliminates secondary chemical waste. This aligns with the Moon’s limited resources and reduces the environmental footprint of manufacturing on the lunar surface.
Digital twin: DEIMOS enhances reliability
Alongside the physical hardware, the team created DEIMOS (Digital Environment for Intelligent Modeling of Operational Systems), a digital twin of the injection-molding process. By feeding data from real production runs into DEIMOS, the model predicts how different material blends and part geometries will behave—forecasting mold fill, warpage, and shrinkage risks before any material is actually molded.
This predictive capability is vital for lunar operations where material, time, and energy are at a premium. Astronauts could use DEIMOS to simulate a part’s performance, ensuring that the limited feedstock is not wasted on a defective component.
Team composition and leadership
The CERBERUZ effort grew out of MIT’s Space Resources Workshop, a co-curricular program that has been assembling interdisciplinary student teams since 2017. The winning team brings together undergraduate and graduate students from four MIT departments: Aeronautics and Astronautics, Mechanical Engineering, Electrical Engineering and Computer Science, and Materials Science and Engineering.
Key advisors include research scientist George Lordos (lead advisor) and former NASA astronaut Professor Jeffrey Hoffman. Leadership within the team is distributed among:
- Lanie McKinney – team lead, emphasizing design choices that avoid water and unrecoverable chemicals.
- Palak Patel – co-lead on manufacturing and materials characterization.
- Lilly Etzenbach – co-lead on the digital twin development.
- José Soto – pre-processing lead, who highlighted the logistical challenge of handling large volumes of lightweight Zotek foam.
Lordos praised the “quality of leadership” and noted that each sub-team pursued cutting-edge research in lunar sustainability.
Milestones, prize money, and future plans
The competition timeline spanned several phases. CERBERUZ was selected as a Phase 1 winner in 2025, progressed through Phase 2, and secured milestone prizes in both the Prototype and Digital Twin tracks. The final demonstration took place in the summer of 2026, culminating in a total prize award of $925,000. The team intends to reinvest these funds into the Space Resources Works initiative, aiming to further develop and possibly commercialize the technology for both space and Earth applications.
Implications for the Fourth Industrial Revolution
The CERBERUZ achievement exemplifies how Industry 4.0 principles—digital twins, additive manufacturing, and data-driven process optimization—can be adapted to extreme environments. By demonstrating a closed-loop, low-resource recycling loop, the project aligns with broader 4IR goals of circular economies and sustainable manufacturing.
On Earth, the same methodology could be applied to remote mining sites, disaster zones, or offshore platforms where water and chemical supplies are limited. The ability to turn mixed waste streams into functional components without hazardous by-products resonates with the growing demand for clean-technology solutions in the renewable-energy and smart-city sectors.
Key takeaways
- The CERBERUZ system converts lunar packaging waste—including hard-to-recycle Zotek foam—into composite feedstock for injection molding.
- PERSEPHONE operates without water or chemicals, making it suitable for the Moon’s resource-scarce environment.
- DEIMOS provides a digital twin that predicts part quality before manufacturing, conserving limited feedstock.
- The team’s interdisciplinary approach and strong leadership were critical to winning both prototype and digital-twin tracks.
- The $925,000 prize will be funneled back into further research, potentially bridging space-based recycling with terrestrial circular-economy initiatives.
FAQ
What is the LunaRecycle Challenge?
It is a NASA Centennial Challenge that asks participants to devise technologies for reusing, recycling, or upcycling waste generated during long-duration lunar missions.
How does the CERBERUZ system handle thermoset foam like Zotek F30?
It grinds the foam into powder and incorporates it as a reinforcing filler within the molten thermoplastic feedstock, creating a composite material that can be molded into parts.
Why is water avoidance important for lunar manufacturing?
Water is scarce on the Moon, and transporting it from Earth is costly. Processes that rely on water or generate water-based waste are impractical for sustained lunar operations.
What role does the digital twin DEIMOS play?
DEIMOS models the injection-molding process using data from real runs, predicting outcomes like mold fill and shrinkage so astronauts can validate designs before committing resources.
Will this technology be useful on Earth?
Yes. The approach of mechanically processing mixed waste into reusable composite feedstock aligns with circular-economy goals and could be adapted for remote or resource-limited terrestrial sites.
Conclusion
The MIT CERBERUZ team’s dual victories in NASA’s LunaRecycle Challenge showcase a pragmatic, technology-driven path toward lunar self-sufficiency. By converting otherwise unusable waste into functional parts through an electricity-only, water-free process—and by pairing it with a sophisticated digital twin—the project not only addresses the immediate logistical hurdles of a Moon outpost but also offers a template for sustainable manufacturing in the broader Fourth Industrial Revolution. As the space community moves toward permanent habitats, solutions like PERSEPHONE and DEIMOS will be essential to turning the Moon from a waste-laden depot into a cradle of in-situ resource utilization.
