چکیده
Highlights Cottonseed oil (CSO), a cotton byproduct, has advantages for climate change compared to other seed oils. Results show that the cultivation phase is main impact driver all vegetable oils analyzed in this study. Refined CSO (U.S.) can reduce impacts by up 83% as analyzed. Abstract . Edible are major source of and an environmental concern processed food industry. This study consists cradle-to-grave life cycle assessment (LCA) refined U.S. cottonseed global soybean oil, canola palm sourced from Indonesia Malaysia. Considering equivalent deep frying, they on 1 kg basis. Analysis includes sensitivity analyses modeling allocation choices mixes well uncertainty analysis. analyzed, which favors because it co-product. 83%. Overall, was top performer six eight categories evaluated. When ranking oils, preferred choice. Despite being choice, there tradeoffs with CSO, such water scarcity. In context global-scale commercial frying applications, e.g., McDonald’s daily French fry production 9 million tons per day, switching represents potential savings 1,130 2,188 CO2-eq d-1. For fast-food chains seeking their impacts, may be useful applications. However, opportunities exist improvement use efficiency phase, reinforces need continuous improvements agriculture.
