Overview

Simulation study evaluates biorefinery pathways for livestock and crop waste, demonstrating balanced co-digestion optimizes cost, energy, and emissions.

Key Points

To evaluate the technical, economic, and environmental feasibility of converting agricultural and livestock residues into bio-hydrogen, methane, and methanol through integrated biorefinery pathways.
Simulated three integrated biorefinery configurations using Aspen Plus® with a total plant processing capacity of 31.7 t/day (pig manure, cocoa mucilage, and coffee mucilage).
Conducted life cycle environmental assessments using the ReCiPe 2015 Midpoint methodology and evaluated economic viability with standardized engineering cost models.
Scenario 1 yielded 0.15 t/day of reformed hydrogen with an energy preheating demand of 193,365 kJ/h, producing 194.37 t/day of carbon dioxide equivalent in indirect and direct emissions.
Scenario 3 exhibited the lowest direct carbon dioxide mass flow at 9.28 t/day due to carbon utilization in methanol synthesis, but production costs exceeded total projected revenue.
Scenario 2 demonstrated the most viable operational compromise by balancing technical efficiency, environmental impact mitigation, and commercial profitability.
