Sustainable PHA

Fully Biodegradable

Readily Compostable

Fully Customizable

Initial applications for our PHA pellets

We collaborate with you to deliver specifically formulated pellets to meet your unique material performance requirements.

Injection molding
Injection molding

This grade is particularly well suited for rigid, moldable products such as caps, jars, bottles, and other small packaging items that are difficult to recycle.


Our Fiber grade pellets are a sustainable alternative to petroleum-based polyester; for melt spinning of fibers into shoes, activewear, backpacks, rope, etc.


Our Film grade PHA pellets have been developed for film and sheet applications to meet the needs of flexible packaging that is difficult to be recycled.

What is PHA?

Products made from our materials are designed to minimize their impact on the planet and contribute to a truly circular economy.

What is it?
What is it?

PHA is a family of biopolyesters that can be produced naturally by bacteria and other life forms. PHB is one of the many types of PHA.

Why is it unique?
Why is it unique?

Unlike PLA and other biopolymers, PHA can biodegrade in many environments, including the oceans.

Where is it used?
Where is it used?

YOPP pellets can be used in injection molding, fiber extrusion, additive manufacturing, and other plastic substitute applications.

How can I use it?
How can I use it?

We deliver YOPP pellets to melt processors to be formed into a wide range of products.

Biodegradable, Biobased, Recyclable: Isn’t it all the same?

No! These terms are completely different and knowing their differences is key when talking sustainability.

Our Solution

Our PHA biopolymers are biodegradable and biobased. When no longer needed, the goods created from our PHA can fully biodegrade in any environment where biology is


Relates to where the carbon in a material came from. In this case, from living organisms. If it is rapidly renewable, then yes it is biobased.


It means something can breakdown by microorganisms, fungi, etc. Note: Not all of these materials can be fully broken down and only in certain select environments.


The Myth of Recycling.
Only 8.4% of plastics in
the US are recycled.
The rest ends up in

Biobased & Biodegradable

These polymers are produced using rapidly regenerative feedstocks (plants, wastes, residual gases) and will biodegrade at end of life. While some of these polymers only biodegrade in certain environments, PHAs will biodegrade in most natural environments, including the oceans.

  • PHA
  • PLA
  • PBS
  • Starch blends

Biobased & Non-Biodegradable

While these polymers are made using rapidly regenerative feedstocks (mostly plants), they will not biodegrade once they are no longer needed. These polymers have the same molecular structure as their fossil-based counterparts.

  • Bio-PE
  • Bio-PET
  • Bio-PA
  • Bio-PTT

Fossil-Based & Non-Biodegradable

The majority of today's polymers fall into this group. They are made with ancient fossil carbon (from petroleum) and will not biodegrade.

  • PE
  • PP
  • PET

Fossil-Based & Biodegradable

These polymers are produced using ancient fossil carbon (generally from petroleum) but due to their molecular structure, they have the ability to be biodegradable.

  • PBAT
  • PCL
