How MetGen might actually make this happen in the 21st century
Bioproducts people are fond of saying "you can make anything from lignin -- except money" .... so I liked your headline.
Nonetheless -- lignin (in its crude form -- black liquor) is important for providing energy for pulp mills. My understanding is that in modern operations, basically all of it gets burned, and this is an important part of the process economics in P&P (they don't need much "external energy"). So what happens to those operations when we start diverting lignin to other uses?
The future needs different lignins from various fractionation methods of lignocellulosic biomass.
Perfect! This is the way.
