A major point of differentiation for NanoPaper is our knowledge of micro-particle technology and our ability to design polymers that self-assemble on the surface of pulp, which in turn substantially modify the characteristics of the ensuing products. We believe that the impact of novel polymer technologies on the pulp and paper industry can be revolutionary. NanoPaper has developed a number of advanced additives and processes that address the core industry challenges.
- Green Additives for Increased Strength
NanoPaper is developing improved additives to increase strength of paper and board made from recycled fibers as well as virgin fiber. This becomes important as the industry looks for ways to increase recycled content without sacrificing strength. By making paper or packaging with increased strength at a given basis weight, paper manufacturers can utilize less fiber. Customers benefit through stronger, lighter packaging that lowers shipping and transportation costs. This results in a supply chain with a smaller environmental and carbon footprint.
- Advanced Retention & Attachment Chemistry
NanoPaper has developed retention chemistry that overcomes many limitations of current methods. Our technology allows higher loadings of less expensive fillers for office papers, thus decreasing the consumption of virgin pulp and lowering costs without affecting look or feel. Moreover, our attachment chemistry increases retention of optical brightening agents (OBA). OBA loss into wastewater is both an environmental issue and cost driver, so that retaining them on the paper through our technology can offer significant benefits.
- Eco-friendly Coatings for Paper
Nanopaper has developed 100% fluorine-free alternatives to traditional grease-resistant barrier coatings for paper. While fluorinated coatings have been utilized for years to impart oil and grease resistance to paper, recently concern has developed over the health risks associated with these compounds. Legislation has mandated a 95% reduction in these compounds over the next few years, and subsequent elimination by 2015. Nanopaper's extensive experience with polymer-based coatings enables us to develop solutions employing polymers from both traditional and naturally-derived materials.
- Improvements in Paper Processing
In addition to its product development initiatives, NanoPaper is investigating improvements to paper processing intended to improve its efficiencies and decrease its environmental impact. One R&D program is developing treatment additives for wastewater produced by the paper and pulp industry. Another R&D program is developing process chemistries that reduce energy usage of paper and pulp mills through more efficient dewatering or faster drying.
