Polyhydroxyalkanoate (PHA) is our bread and butter, and we produce PHA through green engineering, using food waste like bread crust and oil.
As more Fortune 500 companies are committing to plastic reduction in the coming years, bioplastics, and especially PHA, are generating interest as an alternative to petroleum-based plastic.
But what is PHA? And why are people only talking about it now?
Mother Nature’s microorganisms have been producing PHA granules well before the 1980s when scientists first discovered the capabilities of PHA as a plastic alternative. It’s impossible to know exactly when these microorganisms started producing PHA, but it’s pretty safe to say they’ve been producing PHA for millions of years.
Here’s a high level look at PHA production:
Bacteria need carbon, nitrogen, and phosphorus to feel comfortable to reproduce.
If the bacteria run out of phosphorus, they can no longer make DNA, and in turn, no longer increase their population. They’re starved for phosphorus, but rich with carbon.
Similar to a camel storing fat in its hump when food is scarce, the bacteria store this carbon for a rainy day.
The result is pearls rich in carbon chains.
Bioplastic and petroleum-based plastic are both basically chains of carbon atoms, meaning similar material and thus similar applications.
Now, let’s discuss Full Cycle’s patented process to produce PHA.
We use organic waste as the feedstock to grow the bacteria to make those pearls of PHA.
Organic waste means food waste, agricultural byproducts, paper and cardboard products, among others.
Using organic waste as a feedstock is a major differentiation compared to other biomaterial manufacturers. Full Cycle offers low-carbon intensive and low-cost biomaterial production.
There you have it, Full Cycle Bioplastic; addressing climate change, plastic pollution, and food waste with one solution, catalyzing the circular economy.

The biopolymer PHA has existed on Earth for millions of years since scientists first discovered polyhydroxybutyrate (PHB, in the PHA family) in 1925. Because fossil fuels were abundant, cheap, and readily available in the 1920s, PHA’s material properties did not become commercially interesting until recently.
As we become more aware of the scarcity of fossil fuels and environmental drawbacks of fossil fuel reliance, the desire for a sustainable alternative to petroleum-based plastics has grown.
PHAs: A Compostable Alternative to Plastic. 6 Answers to Your FAQsRead article
Plastic pollution is a problem everywhere. From the plastic bags blowing across our neighborhoods to the island-sized plastic gyres floating in the ocean, we encounter the plastic problem at every scale.
Many are asking what can we do about it? Are there any plastic alternatives that are actually sustainable? What about compostable plastics? Are they really compostable, or is it all just hype to get us to make us think our plastic problem has been solved?
