Life cycle inventory data for power production from sugarcane press-mud

Area of Science:

• Biomass energy conversion
• Sustainable energy systems
• Life Cycle Assessment (LCA)

Background:

• Sugarcane press-mud is a residual biomass with potential for energy production.
• Life Cycle Assessment (LCA) requires detailed Life Cycle Inventory (LCI) data for accurate environmental evaluation.
• Previous studies may lack comprehensive LCI data for integrated bioenergy processes.

Purpose of the Study:

• To present the methodology for calculating the Life Cycle Inventory (LCI) for power production from sugarcane press-mud.
• To establish a comprehensive LCI dataset for a system utilizing sugarcane press-mud as feedstock.
• To support future environmental assessments of bioenergy systems producing bioethanol, biomethane, or hydrogen.

Main Methods:

• Foreground data for bioethanol production was obtained from lab-scale experiments.
• Material and energy flows for purification and power production stages were modeled using Aspen Plus®.
• Life Cycle Inventory (LCI) for catalyst manufacturing was compiled from literature and Ecoinvent database.

Main Results:

• Detailed LCI data for a multi-stage process including bioethanol production, purification, syngas production, and power generation.
• Inclusion of ancillary processes such as biomethane production and catalyst manufacturing.
• A comprehensive dataset suitable for comparative environmental analysis of different bioenergy pathways.

Conclusions:

• The developed LCI provides a robust foundation for environmental impact assessment of sugarcane press-mud valorization.
• The methodology allows for detailed analysis of energy and material flows in complex bioenergy systems.
• This data article facilitates future research on sustainable energy solutions derived from biomass.
