No Certs. No Service.
We hate greenwashing too. We are proud of the research, testing and certifications done to create the drinking straw that can change the world.

The use of PHAs for foodservice applications is a new innovation but the highly biodegradable properties of PHA are well known and have been studied by the scientific community for well over a decade.
The development of phade® involved a rigorous testing and certification process performed by numerous independent labs and third-party certification bodies. When examining any products claiming to be green, sustainable, or eco-friendly, look for these gold standards in testing. We proudly display our certifications, so that when we say that phade® is working better for the planet, you know we have the stats to prove it.
BPI Certified Industrial Compostable

The result: phade® passed the standard requirement (at least 90% biodegradation within six months) in these conditions.
TUV Certified Industrial Compostable

The result: phade® met the standard requirement (at least 90% biodegradation within six months) in these conditions.
phade Industrial Compostable Certifications
Industrial compostability is determined by ASTM D6400 Standard Specification for Labeling of Plastics Designed to be Aerobically Composted in Municipal or Industrial Facilities, which is a pass/fail standard. To pass ASTM D6400, the product must:
- Biodegrade at least 90% within six months.
- Disintegrate such that after composting for no more than 12 weeks, no more than 10% of the product’s original dry weight may be found in a 2 millimeter screen fraction.
- Be non-toxic.
- Contain no Heavy Metals or Fluorine.
BPI has certified our phade® straw as industrially compostable because it has passed ASTM D6400.
TUV Austria – has also certified our phade® straw as industrial compostable using the same ASTM D6400 pass/fail test and certification requirements as BPI.
TUV Certified for Home Compostability
The results: phade® exceeded the standard requirements for certification. Using ISO 14855, phade® biodegraded at least 90% in 90 days (the standard being within one year), and using ISO20200, phade® achieved 100% disintegration within 61 days (the standard being at least 90% of test material reduced to less than 2mm after 26 weeks). phade® passed TUV’s safety requirements for toxicity.
Phade TUV Home Compostable Certification

TUV Austria has developed a home compostable certification and has certified our phade straw as home compostable.
To obtain TUV certification for home compostable, a product must:
- Biodegrade at least 90% within one year (using ISO 14855).
phade met this requirement within 90 days. - Disintegrate such that after 26 weeks of composting at least 90% of the test material has been reduced to less than 2 millimeters (using ISO 20200).
phade achieved 100% disintegration within 61 days. - Be non-toxic such that the product exerts no negative influence on quality of the compost.
- Contain no Heavy Metals or Fluorine.

Marine Biodegradation
ASTM – D6691
The result: met the standard requirement (90% biodegradation in 180 days) in just 98 days. Residual Water Raman Spectroscopy: Complete biodegradation, no microplastics. Residual Water NMR Spectroscopy: Complete biodegradation, no microplastics.
phade Marine Biodegradability Product Testing
ASTM D6691– Standard Test Method for Determining Aerobic Biodegradation of Plastic Materials in the Marine Environment by a Defined Microbial Consortium or Natural Sea Water Inoculum
- ASTM is an international standards setting organization with over 30,000 members who represent producers, users, consumers, government, and academia from more than 140 countries.
- Tests performed at OWS Laboratory in Belgium.
- Marine Biodegradation Test Results: 90% Biodegradation in 98 Days using gas evolution to measure biodegradation.
- Note that the positive control of cellulose (paper) reached 92% biodegradation in the same time period.
- Nothing will ever show 100% biodegradation because the microorganisms consuming the material will grow and reproduce, which accounts for the remaining percentage of biodegradation that cannot be captured through gas evolution.
Residual Water – Raman and NMR Spectroscopy Tests
Raman Spectroscopy
- A non-destructive, analytical technique used in many applications where microscopic, chemical analysis and imaging is required.
- Commonly used by polymer manufacturers to identify small particles in a film or material (for quality control purposes) and by pharmaceutical companies to identify compounds and for quality control purposes.
NMR Spectroscopy
- An analytical chemistry technique used in quality control and research for determining the content and purity of a sample, as well its molecular structure.
- Has an even higher sensitivity than Raman, and provides good resolution even on a very small sample.
Phade Residual Water – Raman and NMR Results
- The remaining water (residual water) after a marine biodegradation test of phade® was collected for additional spectroscopy testing.
- The solids remaining in the water were inorganic salts from the seawater inoculum used in the test.
- Both spectroscopy and NMR spectroscopy showed no phade material remaining in the residual water after biodegradation.
- phade = Complete biodegradation and NO microplastics.
Testing conducted at University of Georgia Lab (Raman Spectroscopy) and Danimer Scientific Laboratory, Athens, GA (NMR Spectroscopy).
