This study explores the physical and chemical characteristics of biomass ash resulting from the direct burning of coffee parchment (CP) to determine its potential as a catalyst in gasification processes. CP, a common residual of coffee production, is usually burned to reduce waste generation, leading to the production of significant amounts of ash. Through the use of advanced analytical methods such as Scanning Electron Microscopy with Energy Dispersive X-ray Analysis (SEM-EDX), X-ray fluorescence (XRF), and Thermogravimetric Analysis (TGA), this study provides a comprehensive assessment of the ash's physical features and chemical composition. The results indicate high levels of potassium and calcium, with minor amounts of magnesium and silicon present in the ash, suggesting its potential suitability for catalytic purposes due to its distinct composition. By comparing the ash with other catalysts derived from biomass, the study underscores its unique properties and potential benefits in improving gasification efficiency and reducing environmental impact. Ultimately, this research supports sustainable management of agricultural waste by proposing the conversion of a widely available residual into a valuable resource for renewable energy production, thereby contributing to the progress of a circular economy. © 2026 Author(s)
