Abstract
The aim of the current study was the evaluation of the environmental performance associated with the production of stevia glycoside powder using conventional and green cultivation and processing techniques; these techniques aim to reduce the bitter aftertaste of stevia glycosides. Environmental performance was evaluated using the Life Cycle Assessment methodology. The data were collected from farmers and stevia-processing companies, as well as from validated literature sources, environmental databases, and a laboratory-scale analysis of the new techniques. Various environmental impact categories, such as climate change, freshwater consumption, and eutrophication, as well as ecotoxicity, were examined. Regarding precision agriculture, it seems that steadily reducing inputs to the fields leads to a reduction in emissions in most of the impact categories studied. The addition of the new processing technologies leads to a further decrease in their environmental footprint.
