In a world-first move, South Australia has enacted a ban on single-use plastic soy sauce dispensers shaped like fish, commonly known as “shoyu-tai” or “Lunch Charms.” Effective from September 1, 2025, this legislation targets pre-filled plastic containers holding less than 30ml of soy sauce, which are frequently used in takeaway sushi meals. The ban is part of a broader initiative aimed at reducing single-use plastics and their environmental impact.
Environment Minister Dr. Susan Close emphasized that these tiny plastic containers often end up as litter, contributing significantly to street and marine pollution. Marine ecologist Dr. Nina Wootton warned that their resemblance to small fish poses a risk to marine life, which may ingest them.
Why Fish-Shaped Soy Sauce Containers Harm the Planet
- They are made of single-use plastic that often ends up in oceans.
- Small size makes them nearly impossible to recycle effectively.
- They contribute to microplastic pollution affecting marine life.
- The production and disposal increase carbon footprint and waste.
While plastic sachets remain legal, the government encourages alternatives like bulk dispensers in sushi shops. The legislation also bans other single-use items, including plastic cutlery and polystyrene containers. Environmental advocates have welcomed the move but stress the need for broader systemic changes, such as reducing plastic production and holding businesses accountable, to tackle ocean pollution more effectively.
This ban positions South Australia as a leader in environmental policy, setting a precedent that other regions may follow in the global effort to combat plastic pollution.
