First, it's a misconception that we are selling mostly to the pulp and paper industry. Actually, our material is sourced from the pulp and paper industry, so it's a high value-added application, but most applications are outside of pulp and paper.
Potentially we often compete against petrochemicals. In the case of biomaterials, it's a very difficult fight. Most biomaterials or bioproducts don't necessarily have all the specifications of petrochemical-based materials, and, of course, these have been spec'd in. Customers expect such a high level of performance even though it may not be necessary. CNC actually enhances the properties of materials and allows bridging the gap in the case of biomaterials. That is just one aspect.
In other applications, for example in oil well services, we have displaced the petrochemicals that were traditionally used, because of the exotic properties of our materials. Our material has a very high-charged density, and we're able to perform much better in lower quantities than the traditional petrochemical-based materials.
