What is the primary difference between PHA and PLA?

The biggest difference is degradability. While PLA is technically compostable, it requires strict industrial composting facilities (high heat and pressure). In contrast, our PHA is home-compostable and marine-degradable, meaning it naturally breaks down in backyard compost bins or ocean water without leaving toxic microplastics.

Does PHA require pre-drying like PLA?

No. PLA and PETG are highly hygroscopic and require careful pre-drying before extrusion or 3D printing to prevent brittleness and stringing. Our PHA filament is stable and can be printed directly without drying, saving significant operational time.

Is PHA safe for food contact packaging?

Yes. Our 100% bio-based PHA (such as our CitrusCycle™ line) is completely safe, non-toxic, and friendly to the body. It leaves no chemical residue upon degradation, making it superior to conventional PETG.

Key Takeaways

PHA is marine-degradable and home-compostable, while PLA requires strict industrial composting facilities.
PHA eliminates the 4-hour pre-drying bottleneck associated with PLA and PETG during 3D printing and packaging processes.
PHA completely degrades into natural organic matter, eliminating the risk of microplastic residue left by traditional bioplastics.

For years, PLA (Polylactic Acid) has been the default "eco-friendly" plastic for 3D printing and packaging. However, as sustainability standards evolve, its limitations have become obvious.

PLA only degrades in industrial facilities, and without proper disposal, it acts much like traditional plastic, taking centuries to break down in landfills or oceans. Enter PHA (Polyhydroxyalkanoate)—a true bio-polymer synthesized by microorganisms that degrades natively in nature.
