Abstract: The carbon footprint and water footprint (WF) is an indicator of environmental effected and water consumption both direct and indirect greenhouse gas emission and water use in manufacturing. CF and WF concept can be applied to companies to evaluate about sustainability of product and production process. This paper aims to evaluate the existing carbon footprint and water footprint of superabsorbent polymer (SAP) process per ton SAP following Thailand greenhouse gas management organization (Public organization) for CF and global water footprint standard, respectively. The evaluation scope is cradle-to-gate (B2B) that cover raw materials transportation, raw materials, process, packing and transferring. Superabsorbent polymer (SAP) have been developed over 20 years in the world. These polymers have ability to absorb and retain large volume of liquid without water soluble. They are made from partially neutralized, lightly cross-linked polyacrylic acid that are low solids levels, and are dried and milled in to white granular solids. SAP are extremely swell to a soft gel in water that in some cases can be up to 99wt% water. The major of SAP consumption is for hygiene application e.g. baby diapers, adult incontinence and napkin. Calculation data base on actual yearly consumption. Simplified flow diagram was calculated, raw material which is small consumption values are grouped and evaluated. Total utilities consumption was calculated that complies with financial report. Calculated values were already deducted administrative activities. Accord to limitation of emission factor, the equivalent factors were implemented for calculation. The evaluation results of total carbon footprint was 4,467.09 kgCO2e per ton SAP which materials, process, raw materials transportation , packing and transferring and were 79.03%, 17.67%, 1.95% and 1.35% respectively. Meanwhile the evaluation results show total water consumption of SAP process requires The results showed total WF of SAP process requires 30.47 m3 H2O per ton SAP, which 99.83% and 0.17% of blue and gray water, respectively. WF of each sector which raw materials transportation 02.00%, material 97.37%, manufacturing process 2.26%, packing and transferring 0.16%.
