How is PHA made?
PHA is made through an industrial microbial fermentation process, which is a fancy way of describing a process that’s similar to brewing beer (or at least, more similar to brewing beer than the chemical process used to produce other bioplastics). We're brewing a plastic alternative!

The fermentation process starts with renewable resources, like plant sugars and vegetable oils. Then it uses bacterial fermentation (through bacteria and archaea cells) to create ‘polyester granules’. These granules are used to create the PHA lining – a cup lining made entirely from renewable resources. The paper cup we apply the PHA lining to is sourced from FSCTM certified forests.
This aligns with the principles of a circular economy.
