Thomaston, GA, July 23, 2026 – GranBio announced today that it has reached a mutual agreement with Borregaard, a Norwegian company that operates one of the world's most advanced and sustainable biorefineries based on wood as a raw material. The agreement is a commercial resolution of a patent dispute concerning European Patent EP/NO 3089998, “Sulfite-Based Processes for Producing Nanocellulose, and Compositions and Products Produced Therefrom”.

“GranBio has built an outstanding technology portfolio since its inception,” said Luiz Oliveira, CEO, GranBio USA. “The team has put a great deal of time and effort into developing breakthrough technologies to solve some of the world’s most pressing challenges and we are keen to expand the licensing of our technologies as well as protect and leverage the value of our IP portfolio.”

Nanocellulose is an advanced material derived from the primary structural component of lignocellulosic biomass. It offers unique, tunable properties that significantly enhance material performance with applications across a vast spectrum of industries, including packaging, composites, coatings, construction materials, personal care, sealants, adhesives, and others. It provides a renewable alternative to petroleum and minerals‑based additives and products, supporting the transition to a more sustainable, circular economy.

“GranBio's extensive nanocellulose platform is supported by more than 23 patent families with over 77 individual global patents covering production processes, compositions, and applications,” said Kim Nelson, CTO, GranBio USA. “It is one of the most promising biomaterials of our time and its real-world impact has been thoroughly demonstrated. I am proud to say that we at GranBio have played a key role in the advancement of nanocellulose.”

The company has developed patented, industry-leading nanocellulose formulations for convenient drop-in use in a wide variety of downstream applications.

GranBio’s proprietary nanocellulose technologies are available for licensing.
