Pyrolysis of Onion Peel Waste: Investigation of Comprehensive Pyrolysis Index, Reaction Mechanism, Kinetic, and Thermodynamic Properties Using TGA Analysis

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
The rising demand for onion production results in significant waste, harming the environment. Onion waste is unsuitable for animal feed and difficult to dispose of due to its strong odor and potential for phytopathogen growth. Pyrolysis is a promising method for repurposing food waste, requiring minimal infrastructure and offering rapid processing and ...
