Abstract
The global demand for potassium-based fertilizers, such as potash, has surged due to its essential role in agriculture. This study explores the potential of agricultural waste, specifically sesame seed waste and rice husks, as sustainable sources for potash production. The aim of the research was to determine the percentage composition of compounds and elemental concentrations in both materials, using X-ray diffraction (XRD) and Atomic Absorption Spectroscopy (AAS) techniques. Results revealed that rice husks contained 38.33% potassium oxide (K2O), 17.26% calcium oxide (CaO), and 6.25% sulfur trioxide (SO3), while sesame seed waste exhibited a higher potassium concentration of 58.04% K2O. Elemental concentration analysis showed rice husks to contain 35.49 mg/kg potassium, and sesame seed waste had a notably higher concentration of 55.91 mg/kg potassium. Both materials demonstrated promising potassium content, positioning them as viable alternatives for potash production. The use of agricultural waste for potash extraction not only offers a sustainable solution for waste management but also provides an eco-friendly, cost-effective source for fertilizer production. These findings suggest that further developments in potash extraction techniques from these materials could significantly contribute to global agricultural and industrial needs.
Soybean is among the world's main commodities, and Brazil depends heavily on chemical fertilizers: approximately 80% of synthetic nitrogen, phosphorus, and potassium fertilizers are imported, with a consumption growth trend of 6%, and, in some crops, fertilizers can account for up to 40% of total inputs. On the other h...

Agricultural residues and biogenic wastes from food production are often poorly managed, contributing significantly to environmental pollution. This research repurposed such wastes as raw inputs for producing valuable products, thereby reducing pollution harmful to humans, animals, and plants. Rice husks, noted for the...

The study aimed to evaluate the potential use of sewage sludge–derived biochar as a soil amendment and nutrient source. Biochar was produced through torrefaction of municipal sewage sludge collected from a wastewater treat-ment plant located in the Upper Silesia region (Poland). The process was carried out at 250 °C fo...
