Researchers at Queensland University of Technology have developed a recyclable and renewable barrier coating for paper and cardboard. Historically industrial coatings have included wax or thin plastic films such as polyethylene or polypropylene. However there is an inherent problem with these conventional coatings in that recycling is often very difficult. The novel QUT approach utilises a unique lignin-based formulation to facilitate the formation of a thin film that acts as a barrier to moisture. The lignin coating technology being developed at QUT is currently maintained as confidential information. We are currently seeking expressions of interest from a commercial partner to participate in a pilot trial and undertake further development with a view to licensing the technology.
