Introducing the first plastic-free, home compostable soy fish dropper.

The problem

These tiny fish are used for seconds, but last centuries, harming the environment and potentially adding microplastic to our food. It’s time to let them go.

We've created a compostable sauce dropper that's soy much better.

Unlike single-use plastics that float around forever, Holy Carp! is made of renewable plant pulp that readily decomposes, leaving nothing behind but nutrients for the soil.

Place in the organics bin or compost and Holy Carp! will disappear in a few weeks.

The tide is turning against single-use plastic, with a ban in South Australia, and more on the way. We've designed Holy Carp! to be Plastic Ban Compliant in all markets.

Our story

In 2020, we launched the Light Soy lamp to shine a light on the big problem with small plastics, like the iconic soy fish, and to help stop ocean pollution at the sauce. Since then, we’ve inspired thousands of people to rethink waste and supported the cleanup of more than 32 tonnes of plastic.

But sushi’s problem with single-use plastic hasn’t gone away.

The soy fish are cute and convenient, but while they serve their purpose for just a few minutes, they can persist in the environment for hundreds of years. Once they escape into nature, they can harm marine life and break down into microplastics… potentially ending up in our food supply.

They’ve become a symbol of a wasteful, linear economy that’s harming both people and the planet.

Almost 40% of all plastic produced each year is used for packaging (source). The world consumes nearly a trillion single-use plastic sachets annually (source), and we estimate that 8–12 billion soy fish have been used since their invention in the 1950s.

Those plastics haven’t disappeared. They remain in landfills and the environment, slowly fragmenting into ever smaller pieces. Scientists now find microplastics everywhere: from the deepest ocean trenches to the summit of Mount Everest and even in our brains.

For the past five years, we’ve been highlighting this problem. But awareness alone isn’t enough. We’ve always wanted to find a better alternative than simply “going without.”

At the same time, single-use plastic bans are coming. A ban has already started in South Australia, and hopefully more will follow.

We've been collaborating with leading sushi restaurants and award-winning designers Vert Design, to create a solution that is practical, planet-friendly, commercial and still provides the same spark of the joy as the original soy fish.

Holy Carp! lets you enjoy sushi without leaving plastic in your wake. It's a small change, but we truly believe every drop matters.

Holy Carp! and a range of sustainable 'sushiware' products will be available in 2026. If you'd like to stock Holy Carp! in your business, enquire now to get the first catch.
