Broadening Compostability Certification: Why Hawai‘i Bill 83 Falls Short

As Hawai‘i County moves forward with Bill 83, a measure aimed at reducing disposable plastic and polystyrene foodware, the intent is clear: protect our environment, align with zero-waste goals, and foster a sustainable future. These objectives deserve strong support; however, the current language in the bill amendment restricts compostability certification to only BPI or CMA. This raises critical concerns that could undermine the very progress it seeks to achieve.

Compostability standards are essential for ensuring that products marketed as “compostable” truly break down in real-world industrial composting conditions. Yet, requiring certification solely from BPI or CMA creates unnecessary barriers for manufacturers and Islanders. BPI and CMA are reputable, but they are not the only entities capable of validating compliance with ASTM standards and other stop gaps of human and environmental safety for compostable products. See here for a comprehensive comparison of certification standards.

By excluding other accredited certifiers, the ordinance risks:

• Limiting innovation: Emerging certifiers and technologies that meet ASTM standards would be shut out, slowing the adoption of new sustainable materials.
• Increasing costs: Businesses may face higher certification fees and logistical hurdles, particularly small local vendors who already operate on thin margins.
• Reducing accessibility: Hawai‘i’s geographic isolation amplifies these challenges, making it harder for local businesses to comply without significant expense or delay.

The bill rightly references ASTM D6400 and D6868 standards which are the technical benchmarks that define compostability in industrial settings. These standards are the backbone of credible certification. Instead of mandating specific organizations, the ordinance should require proof of compliance with ASTM standards from any independent, accredited third-party certifier. This approach ensures integrity without stifling competition or innovation.

A More Inclusive Path Forward

Other jurisdictions have adopted flexible language, allowing certification from any recognized body that verifies ASTM compliance. Being less restrictive maintains environmental rigor, encourages market diversity, and supports local businesses by reducing unnecessary bottlenecks.

Bill 83’s goals are commendable, but its certification clause needs refinement. Compostability should be about science and standards, not brand names. By broadening the scope beyond BPI and CMA, the County can uphold environmental integrity while fostering an inclusive, innovative marketplace that benefits businesses, consumers, and the planet.

By including additional compostability certifiers, Hawai‘i County can champion sustainability for all of Hawai’i without creating exclusivity that hinders environmental protection and progress.
