To arrive at this design, the project team first drew up a set of six criteria. The symbol should be striking as well as easily recognized and recalled. At the same time, it had to be unique and unambiguous so it wouldn’t be confused with other symbols. For practical reasons, it had to be a shape that could be stenciled onto containers. It needed to have some symmetry as well so it would be identifiable in different orientations. Finally, it had to be inoffensive, a design that wouldn’t have negative or problematic associations for any ethnic or religious groups.
