Securing important industry certification opens new opportunities for developing functional, compostable products including straws, cutlery, cups, and food packaging
Woburn, Massachusetts--(Newsfile Corp. - November 13, 2024) - CJ Biomaterials, Inc, a division of South Korea-based CJ CheilJedang and a primary producer of polyhydroxyalkanoate (PHA) biopolymers, has secured Biodegradable Products Institute (BPI) certification for its full range of PHA masterbatches and compounds available to the US market. These products combine the best properties of PHACT™-branded PHA and polylactic acid (PLA), offering enhanced performance and sustainability attributes for a variety of end products, including drinking straws, cutlery, cups, rigid packaging, and flexible packaging.

BPI is the leading certification body for compostable products in the United States, providing third-party verification that raw materials and products meet ASTM standards for compostability in commercial compost environments. Their certification process includes tests for biodegradability, disintegration, heavy metals, and ecotoxicity. In addition to passing these tests, BPI requires that all products also meet their standard of prohibiting intentionally added fluorinated chemicals.

The following PHACT products are now all BPI certified:

Masterbatch

PHACT™ MA1250P
PHACT™ MA1250P-1
PHACT™ MA1250P-2

Compounds

PHACT™ CA1270P
PHACT™ CA1270PF
PHACT™ CA1240PF

New PHA compound leverages CJ's unique amorphous PHA formulation and expands their portfolio of product grades suitable for straw manufacturing that began with their industrially compostable grade: PHACT CA1270P.

Woburn, Massachusetts--(Newsfile Corp. - November 20, 2024) - CJ Biomaterials, Inc., a division of South Korea-based CJ CheilJedang and a primary producer of polyhydroxyalkanoate (PHA) biopolymers, recently completed a series of successful trials producing straws from the new PHACT™ PHA compound: CB0400A. By using their unique grades of amorphous (aPHA) and semi-crystalline PHA (scPHA), CJ has succeeded in developing a compound that is well tailored for straw manufacturing. All PHACT grades used in the compound are certified as OK Biodegradable Marine by TÜV Austria, and marine degradability certification of the final compound is currently underway.

"The market is increasingly looking for safe, biodegradable and compostable solutions for food serviceware applications, such as straws," said Max Senechal, Chief Commercial Officer of CJ Biomaterials. "PHACT CB0400A is an example of how we can rapidly develop and trial unique PHACT PHA compounds that meet market demands for specific performance attributes, such as softer, more durable straws that can also achieve marine degradability certification."

The new CB0400A compound leverages CJ's amorphous grade of PHA, PHACT A1000P, to reduce brittleness in straws and increase durability compared with incumbent compostable polymers. In CB0400A, aPHA is used in combination with S1000P, a new semi-crystalline grade of PHA launched earlier this year. This compound also expands the portfolio of PHACT grades available for straw manufacturing that began with CA1270P, which is well suited for transparent, industrially compostable straws.

PHACT PHA is made from renewable resources, carries US FDA food contact approval, and is certified as biobased by the USDA's BioPreferred program.
