🌌 Sol-Cycle — Cryo-Shatter: Turning Martian Waste into Infrastructure

Team: Sol Cycle
Challenge: NASA SpaceTrash Hack 2025 — Designing a Martian Waste Management System
Prototype Name: Cryo-Shatter
Mission: Revolutionize recycling on Mars through ultra-low-energy waste-to-infrastructure technology.

🚀 The Problem

A 3-year Mars mission with 8 astronauts would produce around 12,600 kg of inorganic waste — plastics, metals, packaging, glass, textiles, and more.
Shipping trash back to Earth is impossible. Recycling it traditionally is energy-prohibitive.
So, how can astronauts turn their own waste into something useful for survival?

💡 The Solution — Cryo-Shatter

Cryo-Shatter transforms Martian waste into concrete-strength building material using Mars’s extreme cold and sound waves.

⚙️ How It Works

1. Cryo Exposure – Waste is left outside overnight to naturally freeze at –87 °C, becoming glass-brittle.
2. Resonant Frequency Shattering – Ultrasonic waves (8–30 kHz) shatter frozen materials by frequency, separating metals, plastics, glass, and ceramics.
3. Material Sorting – Automated sorting yields 15+ pure materials.
4. Ice-Waste Matrix (IWM) – Sorted powders are mixed with Martian ice to form a 23 MPa concrete-strength composite that doubles as emergency water storage.

🧱 What We Built

A working prototype visualization demonstrating:

• Cryo-Shatter process stages
• Ice-Waste Matrix composition
• Structural applications: habitat extensions, domes, greenhouses, and radiation-shielding roads

🌠 Converts 12,600 kg of mission waste into ~180,000 kg of construction materials
⚡ Uses 96% less energy than Earth-based recycling methods
