ALTERNATIVES TO SINGLE-USE SOY FISH CONTAINERS

Single-use soy sauce "fish" containers are common in many sushi and takeaway businesses, but they’re a big contributor to plastic waste. These tiny plastics are rarely recycled, often end up as litter, and can harm marine life.

Luckily, there are practical, stylish, and cost-effective alternatives that align with your business needs and your customers’ expectations.

WHY SWITCH?

• Environmental impact: Small plastics are a major pollutant and escape waste streams.

• Customer preference: More customers want waste-free options and appreciate reuse.

• Cost savings: Buying in bulk and reducing unnecessary use adds up over time.

UPCOMING SOUTH AUSTRALIAN BAN ON SINGLE-USE PLASTIC SOY SAUCE CONTAINERS

South Australia will ban single-use rigid plastic soy sauce containers under 30ml.

This ban comes into effect on 1 September 2025. Banned products cannot be supplied following this date.

LOW WASTE AND REUSABLE SOLUTIONS

Here are four alternatives to consider, each adaptable to different budgets and needs:

1. Self-Serve Soy Sauce Station

• Best for: Dine-in and takeaway customers.

• How it works: Set up a refillable soy sauce dispenser with small reusable cups nearby.

• What to use: Glass or stainless-steel sauce containers, ceramic pourers, or commercial pump-style dispensers.

Tips:

• Clearly label and monitor for cleanliness.

• Offer signage: “Help us reduce waste—only take what you need.”

2. No Soy Sauce Single-use Containers for Dine-In Customers

• Best for: Any business offering dine-in seating.

• How it works: Provide soy sauce in reusable dispensers at tables or a shared condiment station.

• Benefits:

  • Enhances the dining experience.

  • Eliminates unnecessary waste.

Tips:

• Train staff to exclude single-serve sauce for dine-in by default.

3. Refillable Mini Bottles for Regular Customers

• Best for: Loyal takeaway customers.

• How it works: Sell or provide a reusable mini soy bottle (like stainless steel or glass) for regulars to refill. You can use a deposit option for bottles.

• Example: Some businesses offer branded, refillable containers as part of loyalty programs or meal kits.

• Benefits:

  • Encourages repeat business and reuse.

  • Reduces packaging costs over time.

Tips:

• Pre-fill bottles ready to swap for customers.

  
  

4. Bulk Soy Sauce in Compostable Containers

• Best for: Takeaway customers who still need a container.

• How it works: Fill certified compostable cups with lids using soy sauce from a bulk container.

• Compostable options: Sugarcane, cornstarch, or bio plastic cups with lids.

Tips:

• Provide only upon request.

  • Let customers know how to dispose of them properly (e.g., compost bin).

    
    

TIPS FOR SMOOTH IMPLEMENATION

• Ask First: “Would you like soy sauce today?” instead of adding it automatically.

• Start Small: Trial a soy sauce station or compostable option before a full rollout.

• Promote Your Efforts: Let your customers know what you’re doing and why it matters. Display a small sign or create a social media post.

IT ALL ADDS UP

Ditching single-use soy sauce fish is an easy, visible way to show your customers you care about sustainability. Whether you’re using refillable dispensers, bulk pump bottles, or compostable containers, your efforts can lead to lasting change—without compromising on flavour or customer service.
