A review on environmental assessment of thermochemical conversion technologies for energy generation from crop residue

Year: 2024

Type: article

Abstract: The world's energy consumption is on the rise due to the growing population. Biomass has great potential as an energy source for producing solid and liquid fuels from waste. The environmental impact of various biomass conversion technologies has developed a subject of interest between academic and industrial experts. Bioenergy has been adopted as a sustainable and environmentally friendly solution to reduce human-caused greenhouse gas emissions . The life cycle assessment provides insights into the environmental significance associated with the manufacturing chains of biofuels. This review article focuses on biomass conversion through thermochemical processes, including combustion, torrefaction , pyrolysis , and gasification, and analyzes the environmental effects of these technologies through LCA models. In the global warming potential impact category, pyrolysis is initiated to have the least impact related to other thermochemical conversion processes, with the order being pyrolysis < gasification < torrefaction < combustion. In conclusion, thermochemical biomass conversion technologies have the potential to generate fuels with low carbon emission properties compared to open burning.
