Quick and clear answers to your key questions

What is marine-safe PHA?

PHA is a material made through a natural biological process. Tiny living organisms are fed plant-based sugars and naturally produce PHA as they grow. The result looks and works just like regular disposable tableware, but when it's done, the organisms in soil and the ocean break it down completely, leaving nothing harmful behind.

How is PHA different from other sustainable materials?

Unlike recyclable plastics or other compostables, PHA fully biodegrades without leaving persistent microplastics. While most compostables require tightly controlled industrial facilities, PHA can break down in natural environments, including soil and marine conditions. It does not fragment. It returns safely to nature.

What does the transition to PHA look like?

We work with you from start to finish. That means helping you choose the right products, testing them in your environment, and supporting the rollout so everything runs smoothly. We stay involved the whole way through, so switching feels straightforward, not disruptive.

Does PHA perform like conventional plastic?

Yes. PHA looks and works just like the disposable tableware you already use. It handles heat, holds its shape, and performs the way you'd expect, so switching to Terra Sol doesn't mean compromising on anything.

What happens if PHA ends up in landfill or the ocean?

It breaks down. Unlike most compostables, PHA doesn't need to be sent to a special facility to biodegrade. Whether it ends up in soil, the ocean, or landfill, the organisms already present there will break it down naturally, leaving nothing harmful behind.

What bin do Terra Sol products belong in?

Ideally the compost bin, but that's not the whole story. Most compostable materials only break down properly in industrial composting facilities. PHA doesn't rely on that. It breaks down naturally in soil and the ocean, which means it's doing the right thing even when it doesn't end up in the right bin.

Is PHA commercially competitive?

Yes. In most cases, switching to Terra Sol is a material change, not a price increase. We're backed by Australian manufacturing and scalable supply, so you're not paying a premium just to do the right thing.

Who makes the PHA in Terra Sol products?

The PHA in Terra Sol products is made by EcoPHA Biotech, backed by CSIRO and Murdoch University. Through Solara Corporation, a joint venture between Terra Sol and EcoPHA, Terra Sol holds exclusive commercial rights to a scientifically validated PHA supply chain.
