Assessing the energy load and environmental footprint of potash fertilizer production in Iran.

ABSTRACT: The goal of this research was to analyze the energy and environmental impact of KCL and K2SO4 production and provide recommendations for enhancing energy efficiency and environmental practices. Data was collected through face-to-face interviews at two potash plants and the CML methodology was employed to assess impact categories. Inventory data for production inputs were sourced from the Ecoinvent, BUWAL 250, and LCA Food DK databases within the Simapro 8.03.14 software. The results showed that the production of one ton of K2O as KCL and K2SO4, required 7080.82 and 15691.5 MJ, respectively. Electricity accounted for 52.96% of energy input in KCL production, whereas fuel oil constituted 38.39% in K2SO4 production. Energy ratios, energy productivity and specific energy for K2SO4 was 0.40, 0.
