====== 5. Plastics Processing (Stage 2, Pyrolysis for Fuel) ====== * '''Physical Mechanism''': Thermal decomposition (400-600Β°C, low oxygen) breaks polymer chains into hydrocarbons via cracking and depolymerization, yielding gases/liquids (gasoline 30-40%, diesel 40-50%, wax 5-10%). * '''Components''': Pyrolysis reactor ($10K pilot, $100K-$1M full), condenser ($2K) for liquids, emissions scrubber ($5K). * '''Ideas for Optimization''': Use AD scum (80-90% plastics recovery) as input; mild biomass mix tolerated but slows (10-20%)βpre-sort with flotation ($2K). * '''End Goal/Varied Applications''': Turn 10 tons/day (or 2-5 tons post-competition) into fuels/wax ($5K-$10K/day); Earth: Power units; asteroids: Fuel analogs from trace polymers. Ideologically, "distillation" refines waste into usable energy. * '''Time/Cost''': 1-2 hours/ton; $110K pilot.
