The B9 mill with a single machine will replace two existing 1960s vintage machines (No. 7 and No. 8) at the Botany site, increasing capacity from the current 250,000 metric tpy to around 345,000 metric tpy. The new machine will use 100% recovered fiber. Compared with the old machine and facility, the new mill (approximately a $400 million project) will reduce energy and water use per unit of paper production and will improve overall environmental performance of the facility. It will be designed specifically to minimize environmental impacts such as noise, odor, and water discharges.
The new machine will produce lighter-weight, higher-strength packaging grades, not previously available in Australia, which in turn, will allow for a wider range of corrugated box constructions, along with opportunities for innovation, according to Amcor.
