PHA Coffee Cups

The Future of Coffee Cups is Here: PHA-Lined Cups

For the past two years, we’ve been quietly trialing PHA coffee cups—one of the most exciting breakthroughs in sustainable packaging.

PHA (polyhydroxyalkanoate) is a biopolymer created through a natural microbial fermentation process, much like brewing beer. The PHA we use is derived from corn starch sugars and oils. Bacteria feed on these sugars, producing ‘fat’ that forms the raw material for PHA.

What makes PHA truly revolutionary?

• Certified home compostable (AS 5810) – Breaks down naturally in backyard compost.
• Marine biodegradable (ASTM D 6691) – If it accidentally ends up in the ocean, it will safely biodegrade, unlike other bioplastics.

Unlike traditional takeaway cups, PHA-lined coffee cups contain zero fossil-based plastic. However, because PHA is a synthetic polymer (a type of bioplastic), it technically falls under the category of ‘plastic’—meaning we can’t label them as ‘Plastic-Free’ under current regulations.

Why This is Big News

We’re not just launching a new product—we’re looking to transition all our cups to PHA. As pioneers in the home compostable packaging space, we know how important it is to release them at the right price point.

Compared to other compostable cups, PHA cups are the most anticipated innovation yet. With the potential to eliminate 1.8 billion single-use plastic cups used in Australia each year, they represent a massive step toward a truly circular economy.

Performance & Availability

PHA cups work exactly the same as traditional paper cups. We’ve rigorously tested them for:
✅ Leak resistance
✅ Temperature control
✅ Wall thickness
✅ Taste neutrality

Expect them in 8oz, 12oz, and 16oz sizes.

PHA vs. PLA: What’s the Difference?

Most compostable cups on the market today use PLA (polylactic acid), a plant-based plastic derived from corn. While PLA is certified compostable in industrial facilities, it does not break down in home compost or marine environments, often leading to confusion and improper disposal. That’s why we do not offer them.

PHA, on the other hand, is home compostable and marine biodegradable, ensuring it returns to nature wherever it ends up.

What’s Next?

Right now, PHA cups cost 15% more than our current home compostable cups. Instead of raising prices, we’re working on the best strategy to introduce them in 2025.

To disposal:

• Home compost
• FOGO*/Green kerbside bin where accepted
• Dedicated cup recycling program
• Backyard burial
• Landfill bin

Even if this product can break down in the environment, we recommend proper disposal and never in the nature!
