Abstract


Pomegranate peel, a common agro-industrial byproduct, was studied for its conversion into microparticle biochar through pyrolysis at two temperature settings. The peel was oven-dried, pyrolyzed, ground, and analyzed using spectroscopy, microscopy, and conductivity methods. Biochar obtained at higher temperature showed lower yield but improved physicochemical qualities, including larger surface area, higher porosity, more alkaline pH, and enhanced electrical conductivity. These changes were caused by intensified thermal treatment, which promoted devolatilization, mineral concentration, and the formation of aromatic carbon structures. The presence of functional groups and enriched minerals supports the biochar’s role in improving soil fertility, nutrient retention, and overall soil health. This research also aligns with Sustainable Development Goals (SDGs): promoting waste valorization and circular use of resources (SDG 12), improving soil productivity for food systems (SDG 2), contributing to climate change mitigation through carbon sequestration (SDG 13), and fostering ecosystem restoration (SDG 15).
