Abstract

This paper presents the results of a comprehensive study of four types of spent coffee grounds (SCG) obtained using different coffee brewing methods. Thermogravimetric analysis (TGA) was performed to study the thermal behavior of the samples, and elemental and technical analysis was performed to assess their calorific value. The main gaseous components released during the pyrolysis of the samples were identified using Fourier transform infrared (FTIR) spectrometry. The data obtained allowed us to characterize the composition and properties of SCG as a potential raw material for energy processing.
