SQM's products are from natural origin. They are produced from Caliche Ore and Salar Brines, two natural resources found in the Atacama Desert in northern Chile.
In addition, 90% of the energy used in the production process comes from the sun.
SQM has approximately 4,000 hectares of solar evaporation ponds, allowing it to take advantage of significant amounts of energy.
·This method is only possible because the Atacama Desert has extremely high levels of solar radiation, which results in high evaporation rates and facilitates the process of concentration of salts in ponds throughout the year.
·All production processes have environmental impact studies and public access of online monitoring.
This production process makes it the KNO3 source with the lowest Greenhouse Gas emissions in the industry.
This calculation estimates the carbon footprint (tCO2 equivalents) related to the production of potassium nitrate fertilizer by metric ton. All emissions with GWP (Global Warming Potential) are included, and all the direct and indirect emissions from all materials directly related to the production of the particular fertilizer products listed in the Annex and delivered at the harbor.
Additionally, the calculation includes the estimated emissions from purchased energy and indirect emissions resulting from the production and transportation of raw materials and final products.
