Valorization of Cocoa Residues through Pyrolysis: Effect of Reaction Conditions on the Yield of Obtained Products Instituto Tecnológico Metropolitano - ITM - (CO), Colombia The increasing production of cocoa in Colombia is generating a large amount of agro-industrial residues, especially cocoa pod husk (CPH) and cocoa bean shell (CBS). Without proper waste management, these residues may cause environmental problems such as soil contamination and greenhouse gas emissions. This study focuses on the energy valorization of CPH through pyrolysis, which is presented as an eco-friendly alternative for bio-oil production. The biomass was characterized prior to pyrolysis through proximate and elemental analyses. It was then subjected to thermal pyrolysis in the range of 550–700 °C, heating rates of 10 and 100 °C/min, 140 ± 5 mL/min of N₂ (carrier gas), and isothermal reaction times of up to 10 min. Under these conditions, bio-oil yields were calculated. Subsequently, the bio-oil will be evaluated using gas chromatography coupled with mass spectrometry (GC–MS) to estimate its calorific value through empirical models reported in the literature. The results will provide new insights into residues from the Colombian cocoa sector, offering valuable information to strengthen energy recovery pathways, promote the circular economy, and support future studies in agro-industrial sustainability | |
