Overview

Systematic review reveals energy recovery potential and computational trends for plastic and biomass co-pyrolysis in Latin America, highlighting pathways for circular fuel generation.

Key Points

  • Identify global research trends in plastic and biomass co-pyrolysis and evaluate its technological and thermoeconomic potential within Latin America's circular energy value chain.
  • Conducted a bibliometric analysis of global scientific literature from 2021 to 2025 to determine regional research contributions and thematic pillars.
  • Performed thermo-kinetic and thermoeconomic evaluations on a representative case study of empty fruit bunch co-pyrolyzed with high-density polyethylene.
  • Assessed modeling tools including Aspen Plus, COMSOL, and machine learning models alongside a SWOT analysis for industrial implementation.
  • Global publications on co-pyrolysis peaked at 123 in both 2024 and 2025, dominated by China (48%), India (14%), and the United States (11%), while Latin American output remained scarce despite high feedstock potential in Brazil (10.78 Mt plastic) and Mexico (5.9 Mt plastic).
  • Thermoeconomic evaluation showed that catalytic co-pyrolysis requires 303% more energy input than pretreatment, but the energy content of the resulting products exceeds untreated waste by >882 kWh/kg.
  • Machine learning models, including convolutional neural networks, deep neural networks, and LightGBM, predicted gas and bio-oil yields with high accuracy (R² > 0.9).
