What is PHA?
PHA (polyhydroxyalkanoate) is a bio-based polymer created through natural fermentation. It is designed to perform like conventional plastic in everyday use while being capable of safely biodegrading at end of life. It represents a next generation material developed to reduce the long-term environmental impact associated with traditional plastics.
How is PHA different from other sustainable materials?
Unlike many conventional plastics, recyclable plastics or so-called compostable materials, PHA is designed to fully biodegrade without leaving persistent microplastics behind. Many compostable plastics require tightly controlled industrial facilities to break down effectively. PHA can biodegrade in a broader range of natural environments, including soil and marine conditions, making it fundamentally different from materials that merely fragment.
What does the transition to PHA look like?
We guide partners through the full process, from initial consultation and product design through testing, specification and rollout. Our founder-led team remains closely involved to ensure a smooth transition aligned with brand, operational and sustainability goals.
Does PHA perform like conventional plastic?
Yes. PHA is engineered to meet the functional and durability standards required for commercial applications. It offers strength, heat resistance and usability comparable to conventional plastics, allowing brands to transition without compromising product performance.
What happens if PHA ends up in landfill or the ocean?
PHA is designed to biodegrade safely even when waste systems fail. In natural environments, including marine conditions, it breaks down without leaving persistent microplastics behind. It does not require special bins or tightly controlled industrial facilities to begin its biodegradation process.
Is PHA recyclable or compostable?
PHA can be composted in appropriate composting systems and is compatible with certain organic waste streams. However, its key advantage is that it does not rely solely on industrial composting to break down safely, unlike many other compostable plastics.
Is PHA commercially competitive?
Yes. Terra Sol’s PHA products are commercially competitive with conventional materials. In most cases, transitioning to PHA is a shift in material, not an increase in budget. Supported by Australian manufacturing and scalable production, we help brands transition without disrupting operational efficiency.
