Zerocircle | Seaweed-Based PFAS-Free Packaging Materials

Zerocircle's approach starts with seaweed as a rapidly renewing biomass. Red, brown and green seaweed from farms in Gujarat and Tamil Nadu is processed into a powder, which is then converted into coatings and film-like materials. The company describes its processing as low-energy and built to preserve the natural properties of the polymer, avoiding synthetic additives.

The chemistry is designed around the strengths and limits of natural polymers. Rather than forcing the material to behave like plastic, Zerocircle formulates coatings that work with the native structure of the seaweed. This is intended to give stable barrier performance for grease resistance and a predictable end-of-life.

A central part of the delivery model is compatibility with existing production. Coatings are formulated to flow and process on standard converting lines with minimal adjustment, so paper converters can apply them without new capital equipment. This supports a partnership-led expansion model, in which Zerocircle works with distributors, converters and foodservice businesses rather than building every packaging format itself.

Customers engage through a pilot process. Brands trial coated products in real service conditions, then move to production volumes with converter partners. Pilots across restaurant networks in Mumbai, Bengaluru and New Delhi have been reported in the press. Product development follows a stage-gate pattern, with formats listed as available, launching soon or under development on the company's product pages.
