In 2016 The Georgia Institute of Technology won the CommUnity grand prize for their design of a natural herbicide to promote natural alternatives to highly toxic chemical herbicides on Georgia Tech’s campus and in the surrounding community.

Team leader and ESW member Grace Brosofsky experimented with several prototypes before discovering that the chemical d-Limonene, found in the skins of juiced citrus fruits,  would make an effective herbicide. In one of their experiments, Brosofsky and her team found that their prototype outperformed other organic herbicides currently on the market.
