Message• Drop-in biofuels from Kraft BL are cost competitive
• Added value from increased pulp production capacity
• Biofuel production is an efficient way to utilize a pulp mill energy surplus
• Hydrogen supply and refinery energy integration are critical issues for lignin separation and upgrading
