The document discusses harnessing energy from lignin through the LignoBoost process. Lignin is a complex polymer that gives structure to plant cell walls. The LignoBoost process extracts lignin from black liquor produced in pulp mills. This allows the mill to export excess energy rather than upgrading recovery boilers. Test results showed lignin can be profitably incinerated with coal to generate renewable energy. Overall, the process lowers CO2 emissions and allows pulp mills to supplement their income through lignin-based energy exports.
