I don't know if standards are the most important thing right now. Lignin is produced in powder form, which is not always very consistent. What we really need to do is develop technologies that make this lignin powder usable by the plastics industry.
A good example of this is what we're doing with Domtar. The company's lignin powder is transformed into small granules that look like the plastic granules used in the plastics industry to produce moulded or extruded objects.
I don't really see the need to establish standards. It's more a question of developing solutions that allow existing industries to use these new bio-materials.
