Energy and Environmental Simulation of Landfill Gas-Based Power Generation Systems: A Case Study from Macaúbas Landfill, Brazil
Short Introductive summary
This work investigates the energy and environmental performance of electricity generation from landfill gas (LFG) at the Macaúbas Landfill in Sabará, Brazil. A comprehensive Python-based model was developed to simulate thermodynamic behavior, emission profiles, and life cycle impacts of LFG-powered engines (Jenbacher JGS 420 GS-B.L). The simulation integrates real operational data to estimate conversion efficiency and greenhouse gas (GHG) mitigation potential, validated through stoichiometric combustion and assessed under the IPCC AR6 (GWP100) methodology. Preliminary results reveal a net energy generation of approximately 22 MWh per month and a significant reduction in GHG emissions—up to 86% lower than conventional grid electricity. The study demonstrates the potential of LFG valorization as a low-carbon strategy for Brazilian waste management, while also outlining future integration of Pressure Swing Adsorption (PSA) and steam reforming for biomethane and biohydrogen production, advancing circular bioenergy and decarbonization goals.
