GLOBAL TRENDS IN DISSOLVING PULP - SPECTRUM MAGAZINE DEC 2017

According to Rod Young, RISI’s Chief Economic Advisor, the turnaround of dissolving pulp supply and demand over the last decade has been nothing short of amazing. World demand for dissolving pulp began trending steeply upwards in the early years of the current decade and has continued to grow above the rate of GDP. A lot of the increase in demand is due to substitution for cotton. The current estimate is that dissolving pulp demand will hit 7.6 million tonnes this year.

The key challenges are maintaining high yield and productivity while ensuring consistent pulp quality. ANDRITZ technology for the production of dissolving pulp is based on many years of experience with chemical pulp fiberlines and intensive R&D on high alpha-cellulose dissolving pulp grades.

Our experience with biofuels has further led us to design the system with special features considering the optimal methods for by-product recovery and reutilization.
