Polyhydroxyalkanoates

They just sort of sit there.

So the two main ones that are both biodegradable and bio-based are made from compounds PLA and another compound called PHA.

So PLA plastic is chemically made and it's often using wheat or corn starch.

But there's another complexity.

So they could be recycled oil plastics, but they're still made from oil.

So yeah, that's the overview of bioplastics.

But then the PHA plastic, this is the one that PHA compounds can be biodegradable and bio-based.

So PHA naturally occurs and it's stored on microbes as energy reserves.
