ST1-04: Borregaard demo plant for BALI™ biorefinery concept operational

Borregaard is one of the world's most advanced biorefineries with leading positions in lignin performance chemicals, specialty cellulose and wood based vanillin. Over the last five years Borregaard has directed substantial resources towards development of the BALI™ biorefinery concept which includes a sulfite pretreatment step and yields a water soluble lignin. The lignin is easily separated from the cellulose pulp by filtration, yielding a pure cellulose fraction well suited for enzymatic hydrolysis. The concept has been scaled up in a 1.2 MT/day greenfield demo plant which became operational in 2012. Initial findings from the demo plant will be shared.
