Abstract Large amount of wastes are burnt or left to decompose on site at landfills where they cause air pollution and nutrient leaching groundwater. Waste management strategies that return these food agricultural soils recover the carbon nutrients would otherwise have been lost, enrich improve crop productivity. The incorporation liming materials can neutralize protons released, hence reducing soil acidity its adverse impacts environment, security, human health. Biochar derived from organic residues is becoming a source input provides multifunctional values. be alkaline in nature, with level alkalinity dependent upon feedstock processing conditions. This study conducted characterization biochar pyrolysis process eggplant Acacia nilotica bark temperatures 300 °C 600 °C. An analysis was kinds determine their pH, phosphorus (P), as well other elemental composition. proximate by ASTM standard 1762-84, while surface morphological features were measured using scanning electron microscope. exhibited greater yield higher fixed possessing lower content ash volatile components compared eggplant. exhibits ability acacia bark-derived biochar. calcium carbonate equivalent, potassium (K), (P) levels biochars increased temperature increased. results suggest could beneficial resource for storing soil, addressing enhancing availability, particularly acidic soils.

Biochar produced from biomass based Empty Fruit Bunches (EFB) pyrolysis presents an alternative energy source. Biomass through the pelletization process will produce bio-pellets with higher density, while microwave achieves better efficiency and cost effectiveness. This two-step a product longer combustion duration thermochemical conversion efficiency. study aims to utilize EFB waste (pelletization pyrolysis) biochar as renewable approaching commercial standards. mass of 80, 100, 120 g were pyrolyzed in reactor power 450, 600, 850 W, time variations 20, 30, 40 min. The results showed that W 80 optimal conditions highest heating value (26.73 MJ/kg), moisture content (0.48%) volatile matter (12.56%), ash (22.33%), fixed carbon (64.62%). SEM-EDX analysis indicated increase (C) up 67.4%. It is expected combination assisted could become new for producing be commercialized. research was carried out address problem accumulating palm oil mills generating waste.
