Continuous pyrolysis converts low-grade and landfill-extracted plastics into petrochemical-grade hydrocarbon oils and purified resins for virgin-plastic manufacturing and closed-loop plastic-to-plastic recycling. Patented fully-continuous modular reactors (scalable up to 75 TPD) target up to 50% lower CAPEX versus incumbents and include purification tech for TetraPak/MLP resin recovery.
