Terra Sol, an Australian design studio, and EcoPHA, a biotechnology innovator. Together, developing breakthrough solutions in PHA bioplastics.

Most "eco" cups hide a fossil fuel lining - for example PLA, PE or Aqueous.

At Terra Sol, we do things differently. We use PHA lining that is certified compostable, meaning it will disappear naturally in any environment within 3-6 months.

PHA is a unique biopolymer made from natural, renewable sources such as plants, rather than fossil fuels. Unlike most bioplastics, it’s produced through a microbial fermentation process which uses ingredients like plant-based sugars and vegetable oils, resulting in a lining made entirely from renewable materials.

Many people assume recycling is the best solution for paper cups, but most paper cups can’t actually be recycled through curbside bins. In reality, composting is where real environmental progress is being made. That’s why our cups are designed to avoid outdated recycling systems altogether. They break down naturally, safely, and completely - no special infrastructure required.

At Terra Sol, innovation is a team effort. We proudly collaborate with scientists and policymakers, including CSIRO, Murdoch University, Recycle Mate, APCO, local governments and our biotechnology partners at EcoPHA.

Together, we're building real-world solutions that drive lasting change for people and the planet.

Australian made takeaway coffee cups, lids, ice cream cups, straws and cutlery.

We're developing our next range to include plates, salad boxes, smoothie bowls and more, with opportunities to collaborate on personalised designs.
